Are you concerned about your bone health? Do you worry about osteoporosis? According to the CDC, more than 10 million Americans have low bone density that makes them more vulnerable to fractures. For many older people, a fracture can be devastating, reducing mobility and possibly even leading to death. What does the latest medical science tell us about how you can maintain strong bones?

Strong Bones:
You may have seen Halloween skeletons or even chewed the meat off a bone that you then dropped on a plate with a clatter. No wonder we usually think of bones as hard, unchanging objects. Dead bones are. But living bones are quite different. Strong bones are constantly undergoing change. Scientists call it remodeling. One set of specialized cells, osteoclasts, breaks bone tissue down and recycles it. Another set, the osteoblasts, builds bone back. Ideally, their activities are in balance. But if the osteoclasts start to get ahead, as they tend to do while we age, that can weaken bone. The result is low bone mass, known as osteopenia, or even serious bone loss called osteoporosis. This puts a person at risk for fractures.
Who Gets Osteoporosis?
Osteoporosis may have been less common a hundred years ago or more, when many people had to do manual labor that put stress on their bones. That helps for strong bones, so today’s sedentary lifestyles can undermine bone health. Although we think of osteoporosis as typically affecting postmenopausal women, men can lose bone mass too. Medications may contribute to the risk for bone loss. Steroids such as prednisone or methylprednisolone are especially risky if taken for a long period of time. Androgen deprivation therapy for prostate cancer is a risk factor specifically for men.
Diagnosing Osteoporosis:
Doctors assess bone mineral density with imaging called dual-energy X-ray absorptiometry, or DEXA for short. Then they compare the results on the scan to the results they would expect from a 30-year-old person. Results more than 2.5 standard deviations from that could result in a diagnosis of osteoporosis. A person who experiences a fracture without trauma, such as falling from standing height, is also suspected and often diagnosed with osteoporosis.
Non-Drug Approaches to Strong Bones:
People who want to keep strong bones need to focus on exercise. High intensity exercise can be helpful, but brisk walking may be enough. Tai chi and yoga are also popular. If you have been diagnosed with osteoporosis, be sure to check in with your doctor before you start a new exercise program. Building balance and core strength without increasing your risk of a fall (and thus a fracture) would be ideal. Our guest expert, Dr. Kendall Moseley, says the jury is still out on technology such as vibrating platforms, weighted vests or vibrating belts. More studies should show how valuable these could be.
Following a diet that supplies adequate protein, vitamin D and calcium is also crucial. If you must take a calcium supplement, calcium citrate may be well tolerated and absorbed.
How Do Doctors Treat Osteoporosis?
Physicians prescribe several different types of medications to help curb bone less and perhaps even build it back. Some of the oldest and least expensive are the bisphosphonates such as alendronate (Fosamax). These slow bone break down and give the osteoblasts a chance to catch up. They can be hard on the digestive tract, though, and they have been associated with a few rare but alarming side effects: jawbone deterioration and atypical thigh bone fracture. Most people seem to do well on them. Doctors generally prescribe them for up to five years.
Did You Forget Evista?
Another type of osteoporosis medicine is called raloxifene (Evista). It is appropriate only for women, because it is an estrogen modulator. It acts like estrogen in the bones and reduces bone loss. In the breast and uterus, it opposes estrogen activity. Raloxifene does double duty in reducing the risk of breast cancer as well as osteoporosis. Like all drugs, though, it has some worrisome side effects. It can increase the risk of blood clots that cause deep vein thromboses and strokes.
What About Prolia?
Denosumab (Prolia) is a monoclonal antibody that also interferes with osteoclasts. That is how it improves bone density. One thing to keep in mind about Prolia is that stopping it requires careful planning and backup medication. Otherwise, a patient can lose all the bone that was built rather quickly and may suffer debilitating fracture.

Hypertension is often called the silent killer, but osteoporosis might be considered a silent and deadly disorder. This is The People’s Pharmacy with Terry and Joe Graedon.
Terry
00:34-00:41
If an older person breaks a hip, the consequences can be disastrous. They often lose mobility and they may even die.
Joe
00:42-00:50
The focus for osteoporosis is usually on older women, but we should remember that men can also lose bone and become vulnerable.
Terry
00:51-00:57
There are drugs that hurt bone health as well as help build it back. What about supplements or exercise?
Joe
00:57-01:06
Coming up on The People’s Pharmacy, the science of strong bones, lifestyle, medication, and movement.

In The People’s Pharmacy health headlines, semaglutide has gotten a lot of attention over the past few years. If you don’t recognize this generic drug name, you probably do recognize the brand names. Ozempic for type 2 diabetes and Wegovy for weight loss. Both these medications are self-administered injections, but not everyone is enthusiastic about needles.
There’s also an oral form of semaglutide called Rybelsus. The FDA has approved it for treating type 2 diabetes six years ago, and so far it has mostly gone under the radar.
A new study published in the New England Journal of Medicine demonstrated that oral semaglutide at 25 mg a day helped people without diabetes lose significantly more weight than placebo. The randomized trial included more than 300 volunteers and lasted approximately a year and a half. This could be good news for people who have trouble accessing injectable semaglutide or keeping it cold. People taking semaglutide reported improved quality of life. They were also more likely to report side effects, especially digestive distress.

Aspirin has been available for well over 100 years, but the active ingredient has been used by native healers for thousands of years. In 1991, a research article in the New England Journal of Medicine reported that regular aspirin users were 40 to 50 percent less likely to die of colon cancer.
Now, 34 years later, another research paper in the New England Journal of Medicine reports that people taking aspirin had a significantly lower chance of colorectal cancer recurrence. Swedish scientists recruited patients after they’d had their tumors removed. The particular hotspot mutation called PIK3CA. The aspirin dose was 160 milligrams, or roughly half a standard strength tablet daily, for three years. 626 patients were randomly assigned to receive either aspirin or placebo. 7.7% of people taking aspirin experienced a recurrence of their colorectal cancer, whereas 14.1% of those on placebo had a recurrence. That was about a 50% relative risk reduction. 43% of the participants taking aspirin experienced a non-severe side effect compared to 35% of those on placebo. Serious adverse events occurred in 17% of aspirin takers compared to 12% of placebo recipients.
The authors conclude that low-dose aspirin represents an effective, low-cost treatment approach to prevent colorectal cancer recurrence in high-risk, genetically selected patients.

Nutrition experts have praised the Mediterranean diet as a way to reduce cardiovascular risk. It’s also been considered as a way to lower the likelihood of developing dementia and a natural approach to calming inflammation.
Now, dermatologists have announced the results of a study showing that four months on a Mediterranean diet can reduce the severity of psoriasis symptoms. Almost half of the participants following a Mediterranean diet reduced their psoriasis score by 75 percent, and none of those on the control diet did so. The researchers conclude that this dietary strategy could be helpful along with medical treatment.

A new study of acupuncture for chronic low back pain called Back in Action produced positive results. 800 patients were randomized to receive either standard acupuncture of 8 to 15 treatment sessions, enhanced acupuncture, which included 4 to 6 maintenance sessions beyond the standard, or usual medical care alone.
Those in the acupuncture groups had significantly greater reductions in their pain-related disability than those in the usual care group. The authors conclude that, quote, these findings support acupuncture needling as an effective and safe treatment option for older adults with chronic low back pain.

Do cocoa flavanols normalize blood pressure? In the COSMOS study, people with systolic blood pressure under 120 were significantly less likely to develop hypertension if they were taking cocoa flavanols than if they took placebo pills. People whose blood pressure started higher did not get the same benefit. And that’s the health news from the People’s Pharmacy this week.
Terry
06:14-06:17
Welcome to the People’s Pharmacy. I’m Terry Graedon.
Joe
06:17-06:29
And I’m Joe Graedon. According to the CDC, over 10 million Americans over 50 have osteoporosis. That means their bones have become fragile and more vulnerable to fracture.
Terry
06:30-06:40
More than 40 million Americans have low bone mass or osteopenia. What can be done to prevent fractures, disability, and death from weakened bones?
Joe
06:41-07:00
To find out, we’re talking with Dr. Kendall Moseley. She is Associate Professor of Clinical Medicine in the Division of Diabetes, Endocrinology, and Metabolism at Johns Hopkins University School of Medicine. She also serves as medical director of the Johns Hopkins Metabolic Bone and Osteoporosis Center.
Terry
07:01-07:04
Welcome to the People’s Pharmacy, Dr. Kendall Moseley.
Dr. Kendall Moseley
07:05-07:10
Thank you so much for having me today. I’m very excited to chat with you both about a topic that’s near and dear to my heart.
Joe
07:11-07:48
Well, it’s near and dear to our hearts as well, Dr. Moseley, but I suspect that there’s a tremendous amount of confusion when it comes to bones because we’ve all seen skeletons. We’ve all had interactions with bones, perhaps in food. And it just always seems as if bones are so solid. And yet, in reality, bones are constantly breaking down and building up. It’s a very dynamic process. Could you just give us a quick overview on bone physiology?
Dr. Kendall Moseley
07:49-09:21
Absolutely. And I think you’ve highlighted something I always try to stress when I talk to groups of people is that bones are not these inanimate objects. I mean, we’re not these walking, kind of lumbering rocks moving down the street. In fact, we have this very important scaffold underneath our skin that enables us to walk and roll and twist and bend. And without a very strong scaffold, we’re kind of in trouble. So you’re right. Bones are dynamic. Our bones are always building up and they’re always breaking down.
And it’s that process of kind of building up and breaking down that allows us to be flexible, right? If we didn’t have remodeling of our bones, we’d be very stiff and brittle. But it’s that balance, that key balance of how our bones build up and how they break down that really dictates how strong our bones can be.
Clearly, you would prefer a lot more building up than breaking down. And at different parts in our life cycle or different times in our life cycle, we have different balances in that building up and breaking down. If you really want to get into the nitty gritty of the pathophysiology, which I think is important to understand because there are two very different types of cells that treatments for bone disease sometimes impact, we really boils down to these cells, one of which is called the osteoclast. It’s kind of like a little Pac-Man cell that’s responsible for breaking down our bone if it’s an area of injury or a little micro fracture. So that osteoclast will come in and kind of carve out a pit of bone so that the osteoblast, B as in build, can come in and fill in new bone. Again, to rejuvenate that area and to keep your bones flexible.
Terry
09:22-09:34
And I’m assuming that as we get older, there are more osteoclasts or they’re moving faster than the osteoblasts building our bones back. Am I wrong?
Dr. Kendall Moseley
09:35-10:58
No, I think that that’s a wonderful way to think about it. You know, the life cycle is complicated. You know, when I meet patients for the first time, and again, I’m in a metabolic bone clinic, so I see patients who generally come already with a diagnosis of osteoporosis or low bone density.
And when we’re sitting there talking to one another, we say, gosh, why aren’t your bones perfect? And believe it or not, what we do is we go all the way back to childhood because changes happen throughout the life cycle to bones. We build or gain bone. We’re building more bone than we’re breaking down until about the third decade of life.
So those osteoblasts are overtaking the osteoclast to give us nice, strong skeletons. So you might imagine how early childhood insults could impact the bones. In midlife, we have kind of a steady state where the blasts in the clasps are kind of remodeling at a usual rate, generally in balance with one another. At around the time of menopause that women go through, there is a steep decline in bone density, which is driven primarily by those osteoclasts, those Pac-Man cells that break down bone at a much more rapid rate than the osteoblasts are able to keep up with.
And men have an inflection point later on in life. They don’t go through a menopause per se, but about the time, about 70 years of age or so, again, that imbalance starts to shift, which favors the osteoclast or bone breakdown, where again, it’s kind of like a tortoise and the hare story that the tortoise is no longer keeping up with the hare and the bones will break down.
Joe
10:59-11:46
Dr. Moseley, I’m curious as to how things have changed, because I suspect that our ancestors, and when I say our ancestors, I’m not talking about Neanderthals. I’m talking more about our grandparents and our great-grandparents. they were probably spending a lot more time outdoors.
You know, farmers and just workers and, you know, both men and women were just physically more active than we are today. Today, I think we spend a lot of time sitting. And I’m curious as to how our lifestyles have affected bone health over the last, let us say, 50 to 100 years.
Dr. Kendall Moseley
11:47-13:01
Now, I think that that is a fair assessment. We know that activity movement is critical for bone health. You know, in fact, when we talk about the tenets of therapy for osteoporosis and low bone density, one of the things we always have to discuss in clinic is how can we get you more active? What kinds of exercises should you be doing? Because movement really stimulates those bones to kind of rebuild, grow, remodel.
And so absolutely, you know, back in the days when we were out and about, you know, in the farms or, you know, pushing things, you know, down the street. I think we did have a lot more activity related to our bones. I will also counter, though, you know, we didn’t live as long back in the day. And so that graph that I just kind of talked about with this aging process kind of inevitably causing slow and steady bone loss as we get older, a lot of the implications for weakened bone really don’t occur until that later stage in life where women are postmenopausal or men are older.
And so did we really see the full effects of osteoporosis and bone loss, you know, in prior generations when perhaps they didn’t live to be the older ages where the fracture started to manifest or people passed earlier from other conditions that we didn’t have treatments for?
Terry
13:01-13:19
Dr. Moseley, I want to just revisit something you said a few minutes ago and really bring it back up because a lot of people think of osteoporosis as a women’s problem. And you mentioned men get osteoporosis too. Tell us a bit more about that.
Dr. Kendall Moseley
13:20-14:28
Terry, thank you for bringing that up. It is a very important point. And oftentimes, you know, my practice is a lot of women in my practice, and oftentimes women will bring their significant others or their spouses and they listen to my spiel and they kind of turn to their spouse or significant other and they say, well, gosh, Maybe that means we need to screen you as well. And it’s true.
So men do get osteoporosis. It is a misconception that this is a woman’s disease. Statistically speaking, about 10 million Americans in the United States have osteoporosis greater than the age of 50. About 8 million of those individuals being women, 2 million being men, although even that statistic I counter. One big point is that we really under-diagnose osteoporosis. We don’t name it when we see it, and secondly it relies upon screening for osteoporosis and as we’ve just said men really we don’t see this as a man’s disease so are we screening men to even be able to make the diagnosis in that portion of the population so absolutely bones thin at different times in our lives but there are still other factors other disease states other medications that can threaten a man’s
Joe
14:28-14:56
skeleton just as easily as it can a woman’s well you mentioned medications and of course a lot of men who are diagnosed with prostate cancer are given hormone suppressing drugs, what we call antiandrogens. And I suspect that has a profound impact on bone strength and not just in men, in women too, because testosterone people think, oh, that’s a man’s hormone, but it’s responsible for bone strength in both men and women.
Dr. Kendall Moseley
14:57-16:11
Right, right. No, absolutely. So one of the biggest offenders and we, you know, the term is iatrogenic, meaning sadly, we as doctors do this to patients, I mean, deliberately, because oftentimes we’re treating another disease state and we have no choice, but we do give patients oftentimes medications that have side effects that directly hurt the bone.
One of those medications, in fact, is androgen deprivation therapy. So on prostate cancer with a goal to get testosterone levels to zero, we give them these hormone blockers. And it’s kind of like a menopause for men that they go through when we have that low testosterone. We know testosterone is converted into estrogen. So that causes low estrogen in men, which can hurt the bones. Women, there’s a corollary with breast cancer.
So our breast cancer survivors, we treat with drugs such as aromatase inhibitors, where again, we render estrogen levels to zero. And we see oftentimes a significant amount of bone loss associated with those medications as well. Probably the worst drug that we use, but oftentimes very, very necessary for patients with chronic inflammation or autoimmune disease would be things like steroids. So steroids, I always refer to as somewhat dirty drugs.
You know, if you need them, you need them, just like anti-cancer therapies. But those medications as well can really thin bones through a number of different mechanisms.
Joe
16:12-16:36
So the anti-estrogens for breast cancer, the anti-androgens for prostate cancer, and the corticosteroids that are used for so many different conditions, including autoimmune disease and asthma and COPD, all of those medications can have a profound effect. Should everybody who’s taking one of those medications get a bone scan?
Dr. Kendall Moseley
16:37-18:07
In my humble opinion, absolutely. And I think most guidelines would agree. I, you know, it depends on timing. So the low hanging fruit, the easy answer would be with your anti-estrogen medications and your anti-testosterone medications. And certainly if you know an individual is going to be treated with those drugs, it’s usually for a longer period of time.
So anti-estrogen medications upwards of five to 10 years in many breast cancer survivors. Anti-androgen medications oftentimes not as long, but sometimes two years or more. And in those patients, you absolutely do want to get a screening bone density test and anticipate that in fact those medications are going to thin the bones and ideally jump ahead of that problem.
And again, we have interventions we can use pharmacologically and lifestyle-wise to anticipate the bone loss and obviously treat it before it becomes a problem. Steroids are a little bit trickier. Steroids in general, we say that if a patient is going to be on a dose of prednisone or an equivalent of 5 milligrams or more for 3 months or more continuously, that would be a dose at which you certainly would want to get a screening bone mineral density test, potentially treat to prevent bone loss, depending on what that screening bone mineral density test shows, and then follow the patient more closely.
We’re not as worried about the inhaled steroids. We’re not as worried about steroid injections that patients oftentimes will get for joint pains and arthritis. It really is the systemic steroids that cause the most problems.
Terry
18:08-18:15
You’re listening to Dr. Kendall Moseley, Medical Director of the Johns Hopkins Metabolic Bone and Osteoporosis Center.
Joe
18:16-18:21
After the break, we’ll learn the difference between osteopenia and osteoporosis.
Terry
18:21-18:24
If you break a bone, does that mean you have osteoporosis?
Joe
18:25-18:27
What are the options for treating osteoporosis?
Terry
18:28-18:30
Exercise might be helpful. Which ones are best?
Joe
18:31-18:33
Should you be wearing a weighted vest?
Terry
18:39-18:42
You’re listening to The People’s Pharmacy with Joe and Terry Graedon.
Joe
18:51-18:54
Welcome back to The People’s Pharmacy. I’m Joe Graedon.
Terry
18:55-19:13
And I’m Terry Graedon.
Joe
19:13-19:21
Today, we are talking about bones. How would you know if your bones are strong or vulnerable to breakage?
Terry
19:21-19:27
What options are available to maintain bone health? Are some exercises better than others?
Joe
19:27-19:52
We’re talking with Dr. Kendall Moseley, Associate Professor of Clinical Medicine in the Division of Diabetes, Endocrinology, and Metabolism at Johns Hopkins University School of Medicine. Dr. Moseley is Clinical Director of the Division of Diabetes, Endocrinology, and Metabolism at Johns Hopkins. She’s also Medical Director of the Johns Hopkins Metabolic Bone and Osteoporosis Center.
Terry
19:53-20:17
Dr. Moseley, I think there are a lot of kind of long, complicated words that we need to deal with in this interview that people may have heard or maybe not have heard, but are not completely certain what does it mean. So let’s start with the difference between osteopenia and osteoporosis.
Dr. Kendall Moseley
20:18-24:09
Right. I think that’s a great question. There’s a lot of big words in the bone
field, and those would be the big ones that patients bring to the office. So we have to think about bone density and bone health and bone strength along a spectrum.
So, you know, spectrums are uncomfortable for a lot of people. We like to have our bins, our diagnoses. And so in the bone world, we divide things into normal. We say osteopenia, although we are getting away from that term. We more so use low bone density and then frank osteoporosis.
And the World Health Organization would define those three terms based on a T-score. And what is a T-score? So To make a diagnosis, to screen for osteoporosis, we use a very specialized scan called a DEXA scan. It’s a dual energy X-ray absorptiometry scan. You can see why we call it DEXA. And it’s basically a fancy X-ray. And it’s a 2D interpretation of bone quantity, usually looking at the spine, looking at the hip. And it’s two different locations in the hip. It’s the total hip and the femoral neck.
And sometimes we even look at a forearm in certain circumstances and disease states. And it’s that fancy x-ray, again, that we use to follow osteoporosis, but more importantly, to diagnose it in those in whom we’re worried that they have thinner bones. That T-score is really just a standard deviation. And the standard deviation is that individual’s bone compared to that of a 30-year-old, which seems very unfair. But as I said earlier in the segment, we really gain bone until about the age of 30. So we’re kind of comparing that patient to what their ideal should have been back in the day.
A T-score, anything between 0 and negative 1 is considered normal, so normal bone density. Anything between negative 1 and negative 2.5 or 2.4, excuse me, is considered low bone density or osteopenia. And anything less than or equal to a negative 2.5, again, negative 2.5 standard deviations from normal is considered osteoporosis. And that’s what spits out on the reports, and that’s oftentimes what patients bring to the clinic.
Although it’s very, very important to insert a big caveat here. People with low bone density or osteopenia can still fracture. In fact, the majority of fractures, which is the take-home message, we’re trying to prevent broken bones, the majority of people who fracture actually are in the osteopenia or low bone density range as compared to the osteoporosis range bone density. So if someone comes to clinic and maybe that DEXA scan says the T-score is a negative 1.5 or it’s a negative 1.8, which technically, again, is osteopenia or low bone density. If that same patient has also had a fracture, a fragility fracture, that patient has osteoporosis.
So it doesn’t matter to me what this screening scan shows. If that bone has broken in a fragility manner, and gosh, I get that question all the time, too, so I’m going to beat you to it. What is a fragility fracture? This is a fracture of the spine, hip, pelvis, wrist, upper arm from standing height or less.
So slipping outside on an icy street and bracing your fall with your wrist, if you break that wrist, that is a fragility fracture. Stepping out of the bathtub and maybe the floor is a little bit slippery and you come down hard on your hip and you have a hip fracture, that is osteoporosis.
Falling out of a two-story building or a motor vehicle accident and you break your pelvis, that’s just lucky, you know, walked away with just one broken bone. So, again, fragility fractures, no matter what that bone density test is showing, whatever that score says, if you have a fragility fracture, you have a diagnosis of osteoporosis, that should be treated. It’s akin to having a heart attack, right? I don’t need a cath if you’ve had a heart attack to tell me you have cardiovascular disease and we have to take that seriously.
Joe
24:09-24:51
I’ve got a question for you because our grandson, who’s seven, was running the other day at camp and he tripped and he fell and he broke his arm. That happens a lot to kids. You know, they fall off the jungle gym or they fall off their bicycle and they land and out goes their arm and boom, they’ve broken it. Now, they don’t have osteoporosis.
Why would a woman who falls in a similar situation, maybe while riding a bicycle, why would she be automatically defined as osteoporotic?
Dr. Kendall Moseley
24:53-26:07
Well, a woman who falls off a bicycle, that’s considered traumatic, right? So maybe it’s less than standing height because she’s sitting down on a bicycle, but she’s fallen off of a moving object going presumably at a fairly rapid speed and you get entangled in the wheels, etc.
So I would probably talk through the logistics of that particular fall, and I would probably walk away saying that was more traumatic than atraumatic. Getting back to kiddos, they’re a different bird. So again, falling off of a jungle gym, that’s from a height higher than standing height.
Kiddos also have just very different bones. So their bones are kind of built to be a little bit more flexible. They’re a little bit more rubbery. They remodel at a faster rate. And so they do oftentimes get these fractures, you know, tripping, falling, bonking their heads. We had that a couple of weeks ago in our household. We know those fractures heal very rapidly.
Where we start to worry in kiddos, and this is probably beyond even the scope of our discussion today, is when there are multiple fractures, low trauma fractures, you know, situations in which it doesn’t make sense that that arm or that leg breaks. And then there’s a whole host of genetic conditions that oftentimes we will screen for to make sure that, in fact, that child doesn’t have a metabolic disease.
Terry
26:07-26:42
Well, I think it’s important for parents to realize that a situation like that requires extra attention. But we’re not going to follow through on that any further. What I’d like to do is go back to your idea that a fracture might institute treatment.
And what I mostly hear from people my age, women my age, is that they have been told by their doctor that they have to take a drug because of the osteoporosis.
Joe
26:42-26:47
And a lot of them don’t want to take a drug. Or the osteopenia in some cases.
Terry
26:47-27:08
Or the osteopenia. And the most popular drugs are the bisphosphonates like alendronate, which used to be called Fosamax. So what options are there for treating osteoporosis? Is bisphosphonates where you start? Or are there other things people can do?
Dr. Kendall Moseley
27:10-29:57
Now, when I talk to patients, I always break it down into, gosh, what are things that you can leave here with? What is your to-do list going to look like? And that can be things like calcium, vitamin D, exercise, protein, other healthy lifestyle interventions, and we can get into that absolutely.
And then there’s things that maybe I need to do, you know, when the prescription pad may need to come out. When we think about osteoporosis and how we treat osteoporosis, again, we love our bins in medicine. It helps to organize our thoughts and kind of talk to people about how we’re thinking about their disease state. And osteoporosis is no different. We think about it on a spectrum. So is the osteoporosis mild?
You know, in a mild case of osteoporosis, maybe just low bone density, no prior fractures. We sometimes use a tool called a FRAX calculator that comes up in the guidelines. If we’re seeing signals that things are generally fairly positive, we might just recommend lifestyle interventions, calcium, vitamin D, some good exercise, protein, et cetera. As we move further down into the different bins, we get into different categories. So moderate osteoporosis or low bone density, where again, the DEXA scan is giving us data, we don’t like to see the numbers are decreasing. There’s maybe an increased falls happening at home. The FRAX calculations are more elevated.
That might be a category in which, in addition to lifestyle interventions, we might recommend medical therapy, usually something more mild. You know, if we think about it as a swimming pool, we start in the shallow end and get a little bit deeper. That might be an oral bisphosphonate. For women, we use things called selective estrogen receptor modulators, which act on the estrogen receptors within the bone. As we wade deeper into the pool, we get into the more, you know, severe osteoporosis or, excuse me, high-risk osteoporosis or severe osteoporosis. In those categories, that’s when we start using, again, in addition to lifestyle interventions, the calcium, the vitamin D, and the exercise, that might be a place at which we do start to recommend more intense pharmacotherapy. That might still just be an oral but it may be an infusion, it may be an injection, depending on the case.
What I think, though, doesn’t always matter. I think everything comes down to forming a relationship with a patient and talking through what the patient’s concerns are about their bones, what their concerns are about the logistics of a medication. Because if I think you need a daily injection, but you don’t want to do anything, there’s no point in us kind of not reaching any sort of conclusion in terms of treatment. If you’re in a very high-risk fracture category, we might want to start with a bone-building drug. But if you tell me all you’re willing to do is an oral pill once a week, I’d rather not let perfect be the enemy of good. And we might start with something milder, despite what I think.
Joe
29:57-30:24
Dr. Moseley, you’ve mentioned exercise a couple of times, and we’ve gotten all kinds of recommendations with regard to exercise. You know, it has to be bouncy exercise. You have to jump up and down. You have to stress your bones. And then we’ve heard from other experts who say, you know, if you do Tai Chi, it’ll actually be good for your bones.
Terry
30:24-30:24
Or yoga.
Joe
30:25-30:37
Or yoga will be helpful. And so there’s just a lot of confusion around the best kind of exercise or it’s just exercise in general. Walking, will that be helpful?
Dr. Kendall Moseley
30:39-32:45
Yes, yes, and yes. So my take home with patients is always just keep moving. Just keep moving. We all have physical limitations, right? There are patients who can’t, you know, run. They can barely walk. Oftentimes they’ll come in in a wheelchair and a walker, but it’s important that they move their bodies. Walking counts in terms of exercise. There are two, you know, big picture issues when we think about exercise and bone or movement and bone. And the first is, yes, is there a way that we can kind of physically tax or stress bone in a way that promotes healthy bone remodeling and bone building. And there are data in individuals who use high-intensity exercise.
There was a trial called the LIFTMORE trial looking at women and men, older women and men, with supervised high-intensity exercise about three times per week and showing, in fact, there was benefit to the bone. And this is heavy weights. This isn’t just your little two or three pounders that you’re using, but in fact, supervise, you know, high weight, high intensity exercise, and they gained bone. Is that possible for all patients, to all patients have access to that sort of exercise and gyms and equipment, et cetera? Not necessarily.
So the second thing we need to think about with exercise and the importance of exercise is, gosh, how do we keep you upright and fracture free by virtue of the fact you’re not falling? So if we can strengthen individuals, lower body strength, core strength, and you can get that just through walking or through yoga or through Pilates, you know, really making sure that you have a sense of self in space, keeping you from falling, that’s a victory in and of itself as well when it comes to bone strength. So, yes, I mean, would we love everybody out there lifting, you know, 30-pound weights and a supervised setting and potentially gaining some bone? That would be lovely.
But I think realistically speaking, we all bring different limitations to a clinical setting. And just moving, again, just getting those legs working, just getting a sense of balance, sending people to physical therapy for balance training and core and posture, that can be just as important as getting them into a gym.
Terry
32:45-33:30
Dr. Moseley, there’s something else I’d like to ask you about while we’re on this topic of physically stimulating our bones. Something that’s gotten some buzz is vibration. And there are people who have purchased pads that they stand on that vibrate to try to help their osteoporosis. there is also a device that I saw, I think it has been cleared or approved, I’m not sure which, by the FDA. You wear it like a fanny pack. It’s a belt called an Osteoboost and it vibrates for half an hour a day, provided you wear it that long. Are these devices of any use?
Dr. Kendall Moseley
33:32-35:28
I think the jury’s still out. I get those questions all the time in clinic because, Again, I’m very encouraged that patients want to feel empowered with their health and they want to do things other than just take a pill or do an injection. I think it’s important. It’s a partnership that way. What can you do? What do I need to do to strengthen your bones?
So vibration plates and these vibratory belts that are out there now, I think they’re trying to get at the pathophysiology of bone remodeling, which is, again, stressing bone, targeting mechanoreceptors that live in the bone that cause release or non-release of hormones that could be detrimental to bone remodeling and bone strength. And I think there’s promise there in the idea that it’s targeting, again, these mechanoreceptors in the bone.
What we don’t have with either the vibratory plates or the belt are fracture data. So there are some data potentially showing stability of bone density with the use of these different devices. There are some data potentially showing some improvement in bone density. With the belt, it was only tested in individuals with low bone density or osteopenia. We don’t know in an osteoporosis population. The vibratory plate data is kind of all over the place. But what we don’t have with those devices is fracture prevention data. And that’s always hard to get. Even in the drug trials, you need thousands and thousands of study subjects to determine if that intervention is going to reduce fracture risk.
So we may never have that information. So what I tell patients when they bring those, you know, pamphlets to the office or that printout or that clipping from a newspaper article is they say, I don’t think that these devices are going to hurt you at all. I think, in fact, they potentially could be beneficial to you. And how can we work those devices into our treatment plan so that, Again, you are doing things at home that may be beneficial to your bone, but I’m also keeping tabs on your bone density. And we, again, can decide together if we need to ratchet up your treatment plan to the point where we need pharmacotherapy.
Joe
35:28-35:38
Dr. Moseley, I’ve been seeing a lot lately about weighted vests or sort of backpacks that are supposed to be good for you. Any thoughts about that?
Dr. Kendall Moseley
35:39-36:37
Weighted vests are going to fall into the vibratory plate category and even these belts. And it’s the idea that you want to put deliberate strain on your bones to encourage them to remodel more actively.
And again, this is a space where we maybe have some data showing stability of bone density, maybe a little bit of improvement in bone density. We do not have fracture data showing that weighted vests are beneficial to bone health. My challenge I have with them is depending on the vest, and there’s so many different types out there, they sometimes can cause low back pain. They can cause posture problems.
We certainly don’t want anyone falling over from their weighted vest. So if there’s any hint that the vest might cause instability in the patient, I tend to be against them. But gosh, if it’s one more tool hanging by the front door that encourages someone to go outside and take a walk with their weighted vest on, by all means, I’m very optimistic that this could be something, again, to motivate people to take their bones into their own hands.

Welcome back to The People’s Pharmacy. I’m Joe Graedon.
Terry
37:56-38:13
And I’m Terry Graedon.
Joe
38:13-38:23
There are now numerous medications to improve bone health, but they all have some side effects. Which are the safest and most effective?
Terry
38:23-38:41
The FDA first approved a drug called raloxifene in 1997 to prevent postmenopausal osteoporosis. The brand name was Evista. Although other osteoporosis medications approved around the same time are still in wide use, raloxifene has almost disappeared.
Joe
38:42-38:52
Why don’t doctors consider raloxifene for osteoporosis? This medication has another important benefit that has seemingly been forgotten.
Terry
38:52-39:18
Today’s guest is Dr. Kendall Moseley, Associate Professor of Clinical Medicine in the Division of Diabetes, Endocrinology, and Metabolism at Johns Hopkins University School of Medicine. Dr. Moseley is Clinical Director of the Division of Diabetes, Endocrinology, and Metabolism and Medical Director of the Johns Hopkins Metabolic Bone and Osteoporosis Center.
Joe
39:20-40:00
Dr. Moseley, we’d like to talk about treatment first and some of the medications that you do prescribe. And I’m just curious about a drug that seems to have been forgotten. I mean, it never really gained much popularity, but it’s, I think, kind of an interesting medication called raloxifene because it has both, I’ll call it pro-estrogen and anti-estrogen activity, which seems like an oxymoron. Like, how could that possibly be?
But could you just give us a quick overview of a drug that seems to have gotten kind of dusty in the dustbin of history?
Dr. Kendall Moseley
40:02-43:08
Sure. I don’t think of it that way as a dusty drug. We actually use a fair amount of it in our clinics because it has a role in osteoporosis care. So raloxifene is what we call a SERM. It’s a selective estrogen receptor modulator. And as you indicated, it has stimulatory properties at the level of the bone and actually inhibitory properties to tissue such as the breast and the uterus.
So raloxifene is actually similar to a drug called tamoxifen that many women and men have heard of it that’s used as an anti-breast cancer medication in that patient population. So raloxifene, for starters, because it’s a selective estrogen receptor modulator, is not to be used in men. It is solely to be used in women. And we generally, as I was talking about those bins of risk, the low, the moderate, the high risk, and very high risk, we generally reserve that medication for individuals in a low to moderate risk category. And that’s because we have data showing that raloxifene, in fact, does reduce the risk of vertebral compression fractures.
And again, we look at different types of bones and different fractures. We don’t have as much data demonstrating that raloxifene actually reduces the risk of hip fracture. And so when we have patients who maybe have low risk or moderate risk osteoporosis, it’s spine predominant, we see that that’s the lowest site. Oftentimes we will use raloxifene. It’s a daily pill. It’s easy to take. It’s easy to stop. It has a relatively low side effect profile.
So probably the first thing I warn women is beware, your hot flashes may come back once you start this medication. Some run for the hills when I bring that up. Others say no problem. It doesn’t typically last forever, but certainly for the first few weeks or so, those hot flashes can come back. The other side effect that’s certainly more serious than the hot flashes would be that it can increase the risk of blood clots and stroke as a result.
So if there’s a patient who has a history of blood clots or a clotting disorder or pulmonary embolus, again, that would not be a medication of choice. The reason it is appealing to a lot of women and certainly even our use in clinic is it doesn’t necessarily come with the more scary side effect profile that some of the other drugs have. So, again, you can start it and stop it at any time without any ramifications, no rebound bone loss. You can take it indefinitely as long as the patient is tolerating it without concern for jaw necrosis or atypical femur fractures that, again, come up with some of our other drugs. So it’s fairly easy to use. It’s inexpensive. We don’t typically have to fight the insurance companies too terribly hard to get it prescribed. So that’s helpful.
And we actually wind up using raloxifene a fair amount for, again, those patients who come in and they acknowledge that their bones are less than perfect. They’re concerned about their bone health, but perhaps they’re similarly concerned about medication side effects. And again, in the interest of not letting perfect be the enemy of good, if what we decide upon is raloxifene, this daily pill that may not have that hip fracture prevention data, it’s certainly better than nothing. So again, in our bone clinics, we do use it.
Joe
43:08-43:51
And the thing that I think a lot of women find very attractive about raloxifene is that it It has a breast cancer prevention piece as well as, as you pointed out, a vertebral fracture prevention piece. So it’s sort of a double benefit.
But let’s move on, Terry, to some of the other medications because, as you’ve already mentioned, there are some pretty serious side effects. And you mentioned atypical femur fracture. We want to talk about the tooth problem. And we want to talk about some of the newer drugs that are injectable that once you get them, it may be in your body for six months or longer.
Terry
43:51-44:04
But let’s take that one at a time. So let’s start with those bisphosphonates that Joe was alluding to. What drugs are we talking about? When do you use them? What do people need to know about them?
Dr. Kendall Moseley
44:06-47:19
Right. So we can start, I guess, with the bisphosphonate category. And bisphosphonates are probably the old guard of the osteoporosis regimen. I mean, they started, you know, greater than two decades ago with use of these. And probably the one most people have heard about is alendronate.
Alendronate is a once-a-week pill that’s a little bit challenging to take. You take it first thing in the morning, full glass of water, nothing else to eat or drink for an hour, no going back to bed. And these medications, the way that they work in the bisphosphonate category is they are drugs that effectively get incorporated into the bone, into the hydroxyapatite matrix of the skeleton. And once these drugs are incorporated into the bone and they come in proximity of those Pac-Man cells, see here those cells come back again.
When those Pac-Man cells come along and encounter these bisphosphonates, they effectively render the Pac-Man cells, the osteoclast, useless. So they can’t break down bone anymore. they’re incorporated into the skeleton, so they do have a lasting effect. And when I talk to patients about these, we kind of think about it like coats of paint, right? So with each year that you’re on these drugs, you kind of paint the wall once again and once again and once again, and the paint can accumulate, which is why there can be concern about long-term use of these medications.
And I’m going to throw five years out there, but there’s no rule that five years is a maximum amount of use you can do these. But after about five years of use, we do start to consider a pause in therapy in the appropriate patient because of these layers of pain and this, you know, potential paralysis of the Pac-Man cell and paralysis of a bone remodeling process can cause adynamic and potentially more brittle bone.
You know, if your bones are frozen and they can’t rebuild and remodel themselves, we worry that that’s not healthy either for the skeleton because we do start to encounter very rarely atypical femur fractures where kind of there’s a hip fracture that happens below the, you know, kind of along the thigh, which is not anticipated, or we can see jaw complications with jaw erosion, that things can get infected, all stemming from this idea that brittle old bone can’t rebuild, remodel, and heal itself as easier as, you know, refreshed bone. There’s an IV formulation of that pill now called zoledronic acid. It’s administered once a year.
So in patients who really aren’t good at swallowing pills, patients who have esophageal disorders, history of ulcers, which can be a side effect of the alendronate therapy or the oral bisphosphonates, this once a year drug can be quite helpful. It’s given through the vein over about 30 minutes. That one, typically three to five, although again, with an asterisk in the appropriate patient, sometimes we go shorter versus longer. But that drug two, similar side effect profile with rare risk, again, of these atypical femur fractures and jaw necrosis.
But I always like to pause there and say, you know, these are rare side effects and we have to always consider the alternative, which are what are our real concerns about you breaking your hip or breaking your spine or losing bone in the context of that new steroid that you’ve been prescribed. So it’s always a balance talking about side effects of medicine, which they all have, and the benefit of the drug at the end of the day and reducing fracture risk. Oftentimes we have to 50 to 60 percent.
Terry
47:19-47:32
And I’m supposing that there’s no really good way to predict ahead of time who might be at higher risk for one of those really awful side effects like an atypical femur fracture.
Dr. Kendall Moseley
47:33-49:37
Yes, I mean, I wish I had a crystal ball. I mean, we do know that there are certain individuals at higher risk for the more rare but real side effects. So jaw necrosis, in general, the risk will be higher in, let’s say, cancer patients. So they get bisphosphonates at much higher doses, much more frequent doses.
But even in osteoporosis patients, and it would typically be in the setting of what we consider to be invasive dental work. So this is if you are having an extraction, you’re having an implant, you’re having a bone graft where there’s kind of deliberate invasion of the jaw bone itself that can become subsequently infected. and the concern is that bone once infected can’t heal itself well and can, you know, erode over time. We get questions a lot about things like root canals or what about, you know, braces.
Sometimes our orthodontists are worried about braces or bridges, caps. Those are not invasive. We’re not getting into the jaw in those contexts. So again, we’re less worried about that and the jaw necrosis complication. Atypical femur fracture is something that typically we have observed, and it’s been really since the onset of alendronate. Women used to get a prescription for alendronate in one hand and hormones in the other hand, and it was see “see you again never.”
So we’ve learned now that with longstanding bisphosphonate use, we can see these atypical femur fractures. And that’s why I gave that five-year number a little bit ago, which is where after about five years of use, We don’t see a precipitous increase in atypical femur fractures, but we certainly start to consider, is this medication actually necessary? Because that long-term use can be a problem.
We see increased risk in individuals on bisphosphonates who’ve also been treated with long-term steroids. Both conditions can cause this adynamic or frozen bone. And we know that Asian women are at higher risk for atypical femur fractures. So that’s something that we always want to consider when meeting with the patient, again, on that yearly basis to decide whether or not it’s appropriate to continue therapy versus discontinue the therapy.
Terry
49:38-50:12
Now, Dr. Moseley, let’s assume that your patient has been on a bisphosphonate for five years, has stopped, comes back to you in a year or two, and you say, that osteoporosis, it’s still a problem. We’re going to move on to the next category of drugs. You have those bone-building drugs, but there’s a problem with them as well. You mentioned before that raloxifene, the SERM, is easy to stop, but some of these bone-building drugs, they could be hard to stop.
Dr. Kendall Moseley
50:13-50:25
Well, I want to kind of push back a little bit on the bone-building. I think the drug you may be referring to is denosumab, which actually is a drug, which is an anti-breakdown drug, first and foremost.
Joe
50:26-50:42
And Dr. Moseley, a lot of people are not familiar with generic names like Alendronate or Denosumab. So we’re talking about Fosamax in the case of the bisphosphonates, and Prolia is the brand name for Denosumab.
Terry
50:42-50:46
Or is it pronounced Prolia [pro-LEE-ya]? I’m never sure exactly how, and I’ve heard it both ways.
Dr. Kendall Moseley
50:47-52:44
I’ve heard it in both scenarios as well. You could probably use them interchangeably. And I’m glad you said that too. The academician in me has been taught never to use the trade names.
But no, the denosumab, the prolia, or prolia, however you’d like to inflect that, that’s the one that’s an anti-breakdown drug that has more anabolic properties. So if you want to gain bone, oftentimes we do see more improvements statistically at the spine and the hip with that every six-month injection.
But indeed, and I’m glad you brought this up, Terry, because it’s important, that drug, once you start it, it can be challenging to stop. That drug works very differently from the bisphosphonates. It is what’s called a RANK ligand inhibitor, which basically interferes with how the osteoclast and the osteoblast communicate with one another. But it’s a monoclonal antibody, meaning it doesn’t get permanently incorporated into the skeleton. Rather, it’s given every six months because it’s almost as though the clock strikes midnight when you stop it.
And all of these cells, all of these osteoclasts that have been kind of paused for the duration of the use of the medication, if you stop it abruptly, they wake up and have a party and can actually break down your bone at a very rapid rate to the point at which we’ve even seen spontaneous vertebral compression fractures in patients who stop their medication without talking with their doctor first. So that drug gets every six months. It is not impossible to stop. In fact, we’re looking as a society at different transition mechanisms, usually, and almost, actually, I’ll say almost always with the use of a bisphosphonate to try to prevent this rebound effect of the drugs to see if patients can stop the medication. but it can be very challenging.
So that drug is not for those who come to see me and don’t want to take anything or those who oftentimes have a difficult time making it to their clinic appointments. That is a drug for individuals highly committed to their bone health and very dedicated to a treatment course of 5, 10 or even beyond that years.
Joe
52:45-53:28
Dr. Moseley, what about estrogen? I mean, estrogen, it seems like a roller coaster ride. Back in the, oh, I’d say 1970s, 1980s, Premarin was the number one most prescribed drug in America. Just about every woman who was going through menopause was put on Premarin. It’ll take away your hot flashes. It’ll build your bones. It’ll make you feel sexy. I mean, it’s the greatest.
And then of course along came the women’s health initiative and then oh my goodness no estrogen it’s too dangerous and now it seems like estrogen is coming back again tell us a little bit about estrogen and bones.
Dr. Kendall Moseley
53:29-55:08
Yes, well I mean, that’s uh, you’re right it’s a very very hot topic now and I think we’re all kind of re-evaluating how we think about estrogen not just for bone health but also women as they’re going through the perimenopause, you know, did we kind of throw the baby out with the bathwater, so to speak?
We love estrogen for bones. You know, as I described earlier, women lose a tremendous amount of bone density through their perimenopause due almost entirely to this decline in estrogen. It’s like we take the brake off of the osteoclasts and they wake up and they break down a lot of bones. So we absolutely like estrogen for bones.
What’s happened though, is that estrogen is really not first-line treatment for osteoporosis or low bone density, in part due to the fact that we do have these data potentially in older women showing increased cardiovascular risk, increased cancer risk. So we don’t typically use it as a first-line drug to treat osteoporosis or prevent bone loss. But if we do see women who are on estrogen for other purposes, maybe they’re on it for vasomotor symptomatology or mood or difficulty with sleeping, We certainly will keep those women off on their hormones, excuse me, and potentially add additional therapy down the road for bone health if we feel that it’s warranted.
So we’re probably going to see that pendulum continue to swing back. There is a committee being formed as we speak to reevaluate this exact question about the role of menopause hormone therapy and osteoporosis treatment to see, again, if maybe we got a little bit ahead of ourselves and underestimated the importance of estrogen and bone health, particularly in younger women. as they go through the early stages of their menopause.
Terry
55:09-55:21
Dr. Moseley, unfortunately, I don’t have these generic names on the tip of my tongue, but drugs like Forteo, for example, now, is that a drug that is meant to build back bone?
Dr. Kendall Moseley
55:22-57:04
Absolutely. I’m glad we’re spending some time on this because it’s a very important category of medications, these anabolic or bone-building drugs that we use in these high-risk fracture individuals. So very low bone density, multiple fractures, oftentimes failing other drugs, where we have to turn to this category of bone building drugs.
And there’s a few, luckily, in that category now. So starting with your self-injection medications for up until about two years, we’ve got abaloparatide and teriparatide, also known as Tymlos and Forteo. And these are subcutaneous injections that patients, in fact, give themselves. And sometimes we see those eyebrows shoot straight up when that seems to be a tall ask for the patient. But it’s a self-injection for up to two years. It’s actually parathyroid hormone, interestingly enough. So we’re harnessing the body’s own hormone, giving it back to patients in a pulsatile fashion, which can increase bone density.
And then the other drug that’s slightly newer approved in 2019 called romosozumab or Evenity, which are subcutaneous injections administered monthly in a healthcare setting for up to one year, so 12 sets of injections. It should be noted that all of the bone-building drugs, the abalaparatide, the teriparatide, and the romosozumab, after that one- to two-year treatment duration have to be followed by an anti-breakdown drug. If they’re not followed by an anti-breakdown drug, either an oral bisphosphonate, an IV bisphosphonate, or denosumab, in fact, those patients very sadly can lose whatever bone they’ve gained while on treatment back down to baseline, which is always a very, very sad day when we see those patients in clinic because it’s a wasted opportunity to build good bone.
Joe
57:05-57:40
Dr. Moseley, there’s one important area that we have not talked about, and that is fall prevention. You know, we talk a lot about exercise. We talk about other lifestyle changes, but avoiding a fall may be the most important thing of all in preventing a fracture of the hip or even a fracture of arms or legs or goodness knows what else. So how can not just women, but older men avoid a fall that could lead to a fracture?
Dr. Kendall Moseley
57:41-59:36
Right. No, I think that’s a tremendous question. In fact, every clinic visit, when I see patients, we go through, have you had any falls this year?
The first step is assessing the home. And I think the majority of falls happen in the home and it might be a throw rug. It may be furniture that’s too close together. It may be, you know, plastic toys from the grandchildren underfoot, pets. I’m not saying get rid of the grandchildren or the pets, but we do have to be conscientious about our home environment to make sure there’s grab bars on the shower.
Make sure that the impediments to just walking aren’t challenging. Some people choose to move to single-story homes, you know, if stairs become too difficult. I think that’s also something to consider. But then there’s also the strengthening itself, the balance and the posture.
So oftentimes we fall when we become unstable. Sometimes we don’t have a choice. There’s neuropathy, excuse me, that sets in due to nerve conditions, diabetes, et cetera. Sometimes there’s low vision that we have very little control over. But those things that we can modify, lower body strengthening, posture, core strength, which certainly over time become weaker, people become more stooped. all of those things lead to increased risk of falls.
And then finally, we have to really, as clinicians especially, reevaluate those medication lists. I think geriatricians or, you know, boneheads, people across the board agree that a lot of times falls happen because of the medicines we put people on. And this can be anything from anti-diabetes medications, which can cause dips in blood sugar and cause some dizziness, to different types of nerve medications that may cause dizziness over treatment of blood pressure, where blood pressure is quite low.
I see many, many falls in the context of maybe overly aggressive medication regimens, or maybe patients just aren’t talking about how they feel dizzy every single time they stand up after that new blood pressure medicine was added. But we really owe it to our patients to make sure that every drug on that medication list needs to be there, particularly as it pertains to fall safety.
Terry
59:37-59:51
Dr. Moseley, we have only two minutes left of time. So I am going to ask you to summarize, please, your pillars of treatment, the things that we all need to take away from our conversation today?
Dr. Kendall Moseley

Oh, so many pillars and so little time. So we started with lifestyle. It absolutely is important that patients really follow as healthy a lifestyle as possible. Calcium is important for bone…
Terry
01:00:03-01:00:04
How much?
Dr. Kendall Moseley
01:00:03-01:00:09
I know there’s a lot of debate. So calcium, the recommendation…
Joe
01:00:07-01:00:09
How much and what kind?
Dr. Kendall Moseley
01:00:09-01:01:27
So exactly. So the boneheads and even the cardiologists agree that calcium for those with established bone disease, again, this is not a healthy community dwelling population, but those who make it into a bone clinic who are at risk for fracture, 1200 milligrams a day, ideally through diet, ideally, but there are dietary restrictions.
So if you have to take a supplement, calcium citrate is the supplement of choice. It’s better absorbed. You don’t have to take it with a meal. And in fact, it does not require an acidic environment for absorption.
Vitamin D, very important. Ideally, we’re shooting for a blood level anywhere between 20 to 30 nanograms per milliliter, depending on what guidelines you look at. And for some patients, that might mean 1,000 units a day. For others, 5,000 units a day. For others, prescription strength. So that’s something to work on with their physician.
Exercise so resistance training and walking counts about 150 minutes per week as high intensity is tolerated and then finally protein we really protein is having its moment so we want to aim for 0.5 grams of protein at least per pound of body weight because we know we lose muscle as we get older and that’s critical for bone health so lifestyle factors and then obviously the pharmacologic strategies as we discussed earlier if absolutely necessary.
