On the topic I would be interested in how many people who take a multivitamin take one with Chromium and Manganese as Louie Helm recently argued against that.
Louie makes two claims. One claim is that for virtually all people, more chromium and manganese is bad. Quite plausible. But he also makes a much stronger claim that these and selenium, molybdenum, and iodine (?!) are not part of natural biochemistry, and so there is no such thing as deficiency. Even if we cannot identify the particular pathways where they go, it is easy to study deficiency in animals. Humans might have different biochemistry, but the prior is that it's all the same. Manganese and selenium deficiency are common diseases of sheep, thus subj...
Since it turns out that it isn't feasible to include check as many as apply questions in the big survey, I'm asking about supplements here. I've got a bunch of questions, and I don't mind at all if you just answer some of them.
What supplements do you take? At what dosages? Are there other considerations, like with/without food or time of day?
Are there supplements you've stopped using?
