Question: What’s the difference between the NADH/NAD+ and the NADPH/NADH ratios?

So the NADH to NAD ratio and the NAD pH to NADP plus ratio are things that are having real consequences as ratios and biochemistry that are dictating what's going on in our body. The NAD pH to NADH ratio is physiologically irrelevant, but is used as a biomarker of niacin status. So if you look at a biochemistry textbook, that's telling you how things work in the body you're going to see constant references to the NADH to NAD ratio or the NAD pH NADP plus ratio. And you're never going to see any reference to the NAD pH to NADH ratio.

Question: What if my ferritin is low, but other iron markers are normal?

I would first see whether getting more iron in your diet raises your transparent saturation or your iron saturation higher than 40%. If it does, then I wouldn't push it but if it doesn't or if your transparent saturation is significantly below 30%, then I think there's room to try to increase iron further.

If pushing iron up isn't the answer, I would try something like milk thistle or sulforaphane, things that are designed to promote gene expression for detoxification are antioxidant defense such as milk thistle and sulforaphane are generally also going to raise ferritin because ferritin is part of the protective response.

Question: Menstrual Migraines, Pregnancy, and HRT

What I think is happening is the estrogen is probably suppressing DAO when it's higher, but because it's staying suppressed, there's compensation that's happening for it to help minimize the histamine level. Whereas when the estrogen is cyclical, it's suppressing DAO when the body hasn't made any adaptations to low DAO. And that's sort of like sometimes women will get very strong problems with histamine coming off of a pregnancy because the DAO has been so high so long that all the other adaptations that you would have in other ways of breaking down histamine or down-regulating histamine receptors or whatever else, have all been... There's been no need for them. And so your body is maximally accustomed to DAO doing all the work for you.

Question: How do I know if biotin deficiency is causing my hair loss and fungal rashes?

The plasma or serum biotin level is not a good marker of biotin status because it's not very sensitive. And so, if you're in the bottom 10% of it, I would definitely take that as a red flag that you might have biotin deficiency, the best test for biotin, well, the gold standard for biotin deficiency is beta-hydroxyisovalerate in the urine after a leucine challenge. I don't know how you'd get anyone to give you that, but the next best thing is to get a urinary organic acid test that has as beta-Hydroxyisovaleric acid on it and I know that the Genova ION panel, which is the one I usually prefer has that, but a lot of other ones do too. So I, if you get one, I would just check and see whether the beta-hydroxyisovalerate is on the list of analytes.

Question: How do you know if skin problems are from zinc deficiency?

I would measure plasma zinc and if the plasma zinc, the sweet spot is around 120. If the plasma zinc is in the 70 to 90 range, that's borderline and if it's below 70, that's very clearly potentially related to skin problems. I think you have your answer right there. If your zinc's at 120, your skin problems, are not due to the zinc deficiency.

Question: Anxiety, Neurotransmitters, and Nutrition

So there's a few trans neurotransmitters that are particularly relevant. Histamine is a key anxiety neurotransmitter. Another neuro-transmitter that's relevant is dopamine and I don't see dopamine as primarily actually causing baseline anxiety.

Measurement of neuro-transmitters is very difficult but you can get some hints and make some inferences. I would say the Genova methylation panel and the Genova ION panel plus sporty would give you more than enough to probe this stuff.

Question: What are the best ways to stabilize blood sugar?

I would definitely be trying to lower the glucose response. And what I would do in such a situation would be to run a series of experiments on the type of carbohydrate, as well as the amount of carbohydrate, as well as the context of the meal to see. I would use that as the maximum and so define the carbohydrate load of the specific foods that you can tolerate within that range, and then once you have that, then you can experiment with other things like what happens if I add Apple cider vinegar to this regiment, what happens if I add whey protein, which can also help, what happens if I add glycine, which can also help.

The test is a great hint at what might be happening. But at the end of the day, what matters is what happens when you eat the meal you always eat.

Question: What are the best natural ways to lower cholesterol?

The top things that I would think of to lower cholesterol levels are number one, I'd get thyroid status thoroughly checked out. Number two, I would consider experimenting with a diet low in saturated fat or diet low in cholesterol to see how responsive your levels are to those things. Number three, I would experiment with some fiber supplements.  Number four, for people who are overweight, then normalizing body composition is an issue. Number five, I wouldn't use pantothenic acid. I would try pantethine.

Question: Does high B12 mean it’s not getting into the cell?

The right way to address that would be to measure serum or urine or both methylmalonic acid MMA, and that's a functional marker that's very specific to B12. If B12 was not getting into the cell, then methylmalonic acid is going to be high.
