Question: If total carnitine is low, should I supplement?

Supplementation does increase the acylcarnitine fraction and total carnitine to near normal levels. But I'm not clear about whether it's worth worrying about. So, if the total carnitine is low, but the free carnitine is normal, then total carnitine is low because the acylcarnitines are low. I wouldn't be too worried about the acylcarnitines being low. I would be very worried if the acylcarnitines were very high and overwhelming the total pool of carnitine, 'cause that would suggest a metabolic problem.

Question: Isn’t taking copper with zinc self-defeating?

No. So, the competition between their absorption is not that bad. And if it was bad, everyone would be deficient in both of them because all foods that contain one, contain the other.

Question: Insulin resistance from fat invading muscle cells?

I think increased free fatty acids in the blood. That's going to be a normal reaction to dietary fat and I think that if you have increased fatty acids than increased glucose, that you have more energy to dispose off. And if you have more energy to dispose of, and you don't dispose off the energy, then that's going to cause insulin resistance.

Question: How do carbonated water, magnesium, and potassium affect pH?

If you drink carbonated water, the CO2 is going to give up hydrogen ions to become carbonic acid, which is going to give up hydrogen ions to become bicarbonate. So making bicarbonate from CO2 is acidic taking bicarbonate is alkaline. So the thing you have to keep in mind here is that the reason bicarbonate is alkaline is because it makes CO2.

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.

Question: What range of folate and homocysteine are good for MTHFR?

So 18 to 22 nanograms per milliliter for serum folate and then for homocysteine, I would say seven to nine, I think eight is right smack in the middle and it's fine. No harm in getting down to five, if you can get there but I wouldn't, if you're in the seven to nine range, I wouldn't worry about it.

Question: Do Ketogenic Diets Lower Glutathione?

And so what a ketogenic diet does is put you in a low insulin to glucagon ratio longterm and the insulin to glucagon ratio is what is used for the body to perceive whether it has enough energy to invest in making glutathione. And so the reason the liver's glutathione is going to go down on a ketogenic diet is because you're in the fasting state.

Glutathione synthesis is a fed state process. It's something that goes down in the fasting state and up in the fed state period. And so if you're using a diet that is mimicking the fasting state and is allowing you to carry out fasting state physiology for a longer period of time than you would be able to go on zero calories, then you're going to mimic the fasting state. And the fasting state is characterized by lower glutathione synthesis. And that's the end of it.

These are the studies we discussed on the ketogenic diet and glutathione levels:

Question: Why do I have a high LDL-C when my diet is on point?

Generally in the presence of insulin sensitivity, more carbohydrates, less fat will lower LDL, but in the presence of insulin resistance, more carbohydrate will sometimes raise LDL.

And if the LDL is only a little bit out of range and the HDL is good, I wouldn't worry too much about it. If the total to HDL cholesterol ratio is under four, especially if it's close to 2.0 or underneath that, then I would be worrying about all the elements a little bit out of the range. But I would look at coconut oil, reducing it, body composition, normalizing insulin sensitivity, optimizing it. And if all those things are done, substituting some more carbohydrate, less fat may help.

Question: Can protein replete glycogen on a low-carb diet?

Yes, it's possible. And I don't know exactly what the dosing is, but I think it's totally possible. It comes at the risk, I don't want to say risk, but at the downside of creating a lot more ammonia. But I think it's quite possible. I think it was Master Nutrition, Energy Metabolism, Lesson 17, it was the one on the evidence around low-carb and athletic performance. And if you look at the studies suggesting low-carb does not compromise athletic performance, the diets are much higher protein than the diets that suggest that it does compromise athletic performance for glycogen levels. And so, I think on a low-carb diet protein is going to probably be a very critical determinant of glycogen levels.

Question: Creatine: do the benefits outweigh the risks for a mid-30s male?

I think that there are borderline no risks to creatine supplementation. I know some people get bloated from it that usually passes. Anecdotally, some people get insomnia. I think if nutrients are balanced and you just stick with it, that'll go away. There's speculation that it could aggravate male pattern baldness, but there's no good evidence of it.

Question: How important are MAT1A SNPs to methylation?

These in principle, could reduce the activation of methionine, but I don't know that there are any studies that have looked at whether that's the case. And so, just because a SNP isn't a gene doesn't mean that it reduces the activity of that gene. In fact, it doesn't mean it does anything even to the protein sequence of a gene because a lot of SNPs don't affect the protein sequence.

Question: How to increase red blood cell magnesium content?

Well, the first thing you want to do is look at your serum levels. And if your serum levels are low, you want to look at your urinary levels. And if your serum levels are not low or especially, if your serum are high, then you want to focus on promoting magnesium absorbed into the cell.

If your serum levels are low, then you probably don't want to focus on that, you want to focus on magnesium intake or retention or absorption. If you're focusing on getting it into the cells, you're looking at insulin sensitivity, insulin stimulation, vitamin B6 and salt. For urinary loss, you're looking at anything that causes too much urinary output, stress. And if you still can't find the answer, you might want to start looking at certain genetic polymorphisms.

Question: Why would ferritin rise on a low-carb diet when iron status is stable?

Well, they sound copper deficient because copper is needed to mobilize iron out of ferritin. Copper is most abundant in plant foods, except that it's also very rich in liver. And it's pretty decent in a number of shellfish, but on a low carb, steak and cheese diet, not only are you deficient in copper, but you are also now pushing your zinc levels up, which will lower your copper absorption. Low white blood cells is, first thing that I'm going to look at is copper levels, especially if the neutrophils are low. And that would very easily explain rise in ferritin.

Dec 21, 2020

Question: What are the best practices for nutrient absorption?

Large meals and fat soluble vitamins. Large meals are the ally of fat soluble vitamin absorption. Fat absorption from poor fat digestion, is the enemy of not only the absorption of fat soluble nutrients, but also the absorption positively charged minerals. There might a few of them missing, but those are the ones that really stand out to me as big nutrient absorption issues.

I wouldn't micromanage these things, but if it is an eminent view where there is a problem to fix, that's when I start thinking a lot about them. But certainly there are more details in the vitamins and minerals 101 course, and what I have gone through right here.

Question: What’s the best prenatal nutrition?

The things that sort of stick out to me are, you don't want to be Vitamin A deficient or Vitamin A toxic, so you're right in the middle of the range. You really don't want to be deficient in anything. Everyone knows about folic iron which is really important, but there's not really a good nutritional status test for choline. Biotin is very important. One third of mothers spontaneously become biotin deficient from pregnancy. And so I think that you want to be at least getting the RGA for biotin. DUS test of biotin status, is beta-hydroxyisovaleric acid, which is found on a blood panel but it is kind of pricey, but is the best. I think all of the nutrients are important, but I would single out those as being the most important to look at.

Question: Supplement Timing and Food Combining for Zinc?

So for zinc and food, the main issue is that, my guess is that a carnivore meat based meal would probably enhance zinc absorption, but that's never really been tested. There's some controversy in the field over whether you should take zinc on an empty stomach or not. So my position is basically like if it's practical for me to take the zinc on an empty stomach, do an empty stomach. And if it's not practical for you to take the zinc on an empty stomach, do it on a phytate free meal - no whole grains, nuts seeds or legumes.

Question: How to approach chronic joint pain?

You definitely want to move the joints that are affected.

So the movement must target the joints that are affected. And you definitely want like 30 minutes a day of just moderate movement, even walking would be great. But then you also want movement aimed at actually supporting the muscles and the proper joint motions and stuff like that. And so that's where weight lifting comes in. And then you definitely want some guidance from a physical therapist who works with athletes at a minimum to guide the form on the weightlifting movements to make sure they're supportive of the joints instead of making them worse. And then eat a nutritious diet and look for inflammatory foods and try to cut them out and see if that improves it.
