Mastering Nutrition

Question: If my tryptophan is low, and I'm on a low-carb diet, would you recommend 5-HTP supplements or tryptophan supplements or both? There are multiple reasons why tryptophan could be low. It could be that you are not eating enough protein, or it could be that you have a high utilization of the tryptophan. I would look in the test and see if the 5-hydroxyindoleacetate is elevated — because if it is, then that would suggest high serotonin production, and that might explain the low tryptophan. If that is the case, you may want to look into other explanations. In this particular case, we have talked about high estrogen levels and how they might be one of those things. In which case the root cause is the high estrogen levels and you need to address it at that level. Repleting the tryptophan maybe isn't necessarily the goal unless you have symptoms that are related to low tryptophan levels. If you're overproducing serotonin, if anything, you might have symptoms that are more related to high serotonin levels.  You might not have any symptoms that are related to low melatonin levels, which is downstream from serotonin, in which case the main negative effect of depleting the tryptophan would probably be related to niacin because tryptophan is used to synthesize niacin — in which case the goal would probably be best served by supplementing niacin instead of tryptophan.  Something to note: if you're trying to put on lean mass and it's not working, it could theoretically conceivably be possible that serotonin overproduction would be depleting the tryptophan to the point where you didn't have enough tryptophan to put on the lean mass you want. If the tryptophan is being diverted into serotonin, that's why it's low, again, judgeable by whether 5-hydroxyindoleacetic is elevated, then it makes no sense to put 5-HTP into the system because your problem isn't that you have low serotonin. If anything, it's that you have a high serotonin.  The only other explanation I would say is if you have a low protein intake, you might need to increase your protein intake. But if that were the case, you would probably see other amino acids more across the board that were depleted and not just tryptophan.  This Q&A can also be found as part of a much longer episode, here: https://chrismasterjohnphd.com/podcast/2019/03/08/ask-anything-nutrition-feb-23-2019 If you would like to be part of the next live Ask Me Anything About Nutrition, sign up for the CMJ Masterpass, which includes access to these live Zoom sessions, premium features on all my content, and hundreds of dollars of exclusive discounts.

Question: What to do if signs and symptoms of zinc deficiency persist despite taking 75 mg zinc gluconate per day. You should do plasma zinc.  Also you know I kind of wonder whether you're taking that right. So if you're taking 75 milligrams of zinc like at one time then it's not surprising because you're absorbing like seven of those milligrams. The rest you are not.  To maximize absorption take them on an empty stomach in 10-15 mg which is typically the smallest dose available.  If you're doing that and the signs, the deficiency persist they're persisting when you're taking that, then it probably isn’t zinc related. If they're persisting until you take that and it goes away, then either you aren't absorbing the zinc well, or you're not taking it right. Those are the two things.  If you're not absorbing it well it could be a general malabsorption disorder, something causing loss of bile, or a polymorphism or genetic impairment in a zinc transporter, or low methylation which all can affect zinc transporters.

Question: Is a high value of arsenic a concern? Yes, arsenic is a toxin. You probably don’t want a lot of it, if it's just a little high it might not cause terrible damage. I would look at methylation if I saw high arsenic, because methylation is needed to get rid of arsenic.  Oh actually I should add that methylation supplements have been shown to help arsenic detoxification in areas of the world where arsenic was a serious concern.

Question Are low polyunsaturated omega-6 values on the ION test a concern? Not the total, but if the arachidonic acid levels are low I would look at low arachidonic acid intake, or inflammation, or oxidative stress. It would concern me because arachidonic acid is important to a lot of physiological functions, but I don't care about the total omega-6.

Question: When high selenium does not come down in response dietary efforts and cessation of supplementation, what's going on? Either there's high levels of selenium in the soil where your food is grown, or you have low methylation because methylation is needed to get rid of excess selenium.

This podcast discusses when it is recommended to take creatine if you don't have the MTHFR SNP, including improving physique and athletic performance, managing rare creatine synthesis disorders, and potential benefits for depression.

Question: When should tryptophan be taken on a keto diet? Night, day, both? Presumably you're doing this to try to increase tryptophan getting into the brain.  The best thing to do is to take it two to three hours away from other protein.  The second consideration is if you have an allotment of carbs that you concentrate at one time of day, then it would be best to take the tryptophan then. With the caveat being if you’re eating protein with the carbs. In that case it would be best to take it away from the protein + carb meal.  This Q&A can also be found as part of a much longer episode, here: https://chrismasterjohnphd.com/podcast/2019/02/24/ask-anything-nutrition-feb-17-2019/ If you would like to be part of the next live Ask Me Anything About Nutrition, sign up for the CMJ Masterpass, which includes access to these live Zoom sessions, premium features on all my content, and hundreds of dollars of exclusive discounts.

Question: Do you think there are true non-responders to creatine, or do you think that those apparent non-responders have some defects in methylation that makes typical doses of creatine sufficient only for other needs. Alex Leaf would be a great person to ask about this and he's not here right now…  [Alex appears] Alex, so Jen's question is are there true non-responders to creatine or do you just think that non-responders likely have some defect of methylation. It means the typical doses of creatine are only sufficient for their needs. Alex: I don't think that methylation is going to be relevant here. When you look at responders and non-responders, the difference seems to be in their ability to uptake creatine into muscle cells from the serum. So, it's very unlikely be related to methylation and it has to probably do with differences in creatine transporter abilities across cell membranes.

Question: How do I bring up low levels of arachidonic acid? Should I supplement with 250 milligrams? What brand is there from well-known company?  If you want 250 milligrams of arachidonic acid, eat an egg. I don't know anything about arachidonic acid supplements yet, except that they exist because you can eat eggs and you'll get plenty. Do you want to try the supplement? Well you can, but I don’t think it’s necessary.  You eat two eggs a day already, so eat four.  The oxidative stress and inflammation will consume the arachidonic acid, so look at that too.

Question: How to interpret the pattern of high citrate, low cis-aconitate, low glutamate, and high glutamine. The aconitate and citric acid are markers on the citric acid cycle where we metabolize most of our energy. If citric acid is high and isocitric acid is low, (this must be the Great Plains Test which doesn't have isocitrate/cis-aconitate) that would indicate oxidative stress. In terms of the glutamate being low --- if your glutamate is low and your glutamine is on the high side, then you probably have ammonia generation from somewhere that you're mopping up with glutamate. That would be my guess, but that's another can of worms to open.
