Question: If undercarboxylated osteocalcin has health benefits, and vitamin K2 decreases it, what does that mean for K2 supplementation? Short Answer: Vitamin K2 helps secure osteocalcin in bone matrix, where it is decarboxylated and released as an endocrine hormone in response to certain stimuli. When released, it acts to optimize insulin secretion, insulin sensitivity, fuel use during exercise, and male testosterone. This is a clip from a live Q&A session open to CMJ Masterpass members.

Finally, the long-awaited results of my self-experiments conducted from September through January are released! First, make sure you get my MTHFR Protocol, my free 7-page quick guide to optimizing and personalizing your methylation status, here: https://chrismasterjohnphd.com/blog/2019/03/01/start-here-for-mthfr-and-methylation The primary abnormalities in my metabolism during this pre-biotin period were 1) 15 minutes of paradoxical rise in ketones after eating rice, 2) paradoxical rise in lactate during fasting that is suppressed by my meals, and 3) a massively outsized lactate response to alcohol. The first two were provoked by an 18-hour fast and the last by undereating prior to the alcohol. These support a deficiency in the biotin-dependent, manganese-dependent, oxalate-poisoned enzyme pyruvate carboxylase. This is long, and if your time is limited, you may want to skip to "The Bottom Line" in this link: https://chrismasterjohnphd.substack.com/p/self-experiments-in-the-biochemically However, there are some major reasons to commit some time to reading the whole report: It serves as a crash course on the most relevant biochemistry of glucose, ketones, lactate, and ethanol across contexts that include general health, diabetes, infancy, and pregnancy. It includes a literature review of all of the relevant "normal" data. For example, what usually happens to lactate during fasting? What is the normal response of ketones to a glucose tolerance test at the 15-minute mark? How high should you expect your lactate to go up when you drink vodka, bourbon, or beer? I have laid out a model of self-experimentation that you can borrow from for your own experiments. There are many thought-provoking nuggets in here. For example: Is it possible that two pounds of extra body fat prevents peripheral neuropathy in me and perhaps others? I make the case that it may. Has your fasting glucose gone up on low-carb? See why mine went down after doing repeated glucose tolerance tests on myself (which I don't recommend at home!) And, learn why I can fast my way to a glucose of 70 or eat my way to a glucose of 70 and I would choose eating my way there every time.

For nearly 20 years, I have strongly suspected that I have a genetic disorder in synthesizing or recycling something that is absent or poorly available from plant foods, is very rich in organ meats, and is not present in any of the supplements I was taking when I was a vegan. After six months of research, testing, and self-experimenting, I now believe what I have been looking for is a mix of moderate genetic defects in biotin recycling, possibly combined with poor cellular uptake of biotin, and definitely combined with a defect in burning long-chain fatty acids for energy. The treatments for this, which I will be testing one at a time, will be high-dose biotin, high-dose riboflavin, possibly high-dose L-carnitine and glycine, and, if needed, an otherwise low-fat diet supplemented with C8-specific MCT oil.

Question: How do I get my ceruloplasmin up if copper doesn't raise it? Short Answer: Usually ceruloplasmin raises with copper, which may be important to protect copper from causing oxidative stress. If it does not raise in parallel, the usual suspects to look at are vitamin A and thyroid hormone. However, in this person's case, his own evidence from self-experiments suggest that he needs antioxidants to lower his transferrin saturation. Lowering his transferrin saturation may be the key to raising his ceruloplasmin. This is a clip from a live Q&A session open to CMJ Masterpass members.

Question: If I'm at risk of heart disease and phosphatidylcholine increases my TMAO, should I stop the supplement? Short Answer: On a scale of one to ten, my concern about TMAO and cardiovascular disease is a three. There are thousands of things that should be given equal weight as potential contributors to heart disease, but TMAO gets the most attention because the Cleveland Clinic has an incredible PR machine to spread their research, which serves to bolster their financial interest in marketing the test. That said, it is not a universal necessity to supplement with phosphatidylcholine. If you are concerned about your TMAO, you can try substituting trimethylglycine (TMG), and ultimately judge the value of each supplement by whether it is helping you in a demonstrable way.

This analysis of the recent study by the Hazen group at Cleveland Clinic published in Nature Medicine claiming erythritol contributes to cardiovascular disease shows the following: Why elevated plasma erythritol is likely to reflect thiamin deficiency and NADPH depletion from insulin resistance, inflammation, and oxidative stress Why the in vitro and mouse study blood clotting likely reflects osmotic stress with no relevance to the use of erythritol as a sweetener. Why I strongly suspect the Hazen group is hiding data, specifically the data that they obviously had a chance to collect and would have clinched their case but appears nowhere in their paper. Why even though I do not use erythritol as a sweetener, were I ever to think about doing so, the new Nature Medicine paper would play no role in my decision.

Question: How do I fix low blood sugar on vegan keto? Short Answer: Consider how important it is for your ketones to be elevated. Most likely you need to eat more protein, which will lower your ketones. I would aim for a minimum of 0.8 grams per kilogram of ideal bodyweight and consider using 1.2 grams per kilogram of ideal bodyweight. If this does not work, consider all of the nutrients involved in energy metabolism — all of the B vitamins, iron, copper, sulfur, magnesium, potassium — but especially biotin and B6 for their disproportionate role in gluconeogenesis. If the protein you need to normalize your blood sugar does reduce your ketones to a level that are not giving you the benefits you are looking for, you could consider raising them with exogenous ketones.

Short Answer: Plasma zinc is the single most important marker of zinc status. Urine zinc may decline faster in deficiency. Hair zinc increases with supplementation but does not decrease in deficiency. Plasma zinc is decreased by inflammation, oxidative stress, the ovulatory and luteal phases of the menstrual cycle, probably pregnancy and oral contraceptive use, and any kind of stress that leads to an adrenal output. If plasma zinc declines despite supplementation, corroborate that this reflects zinc status by showing normal hair zinc and low urine zinc. Use symptoms as the ultimate arbiter of whether zinc supplementation is helping. This is a clip from a live Q&A session open to CMJ Masterpass members.
