There is a boatload of marketing and good sounding crap not based in any science in vitamin land... but certain ones most definitely should be
supplemented by everyone, like vit c.. .we simply cannot get enough from modern diets and the science about how much we need is contested... with the
"mega dose" side making some sense when investigated... and the science is voluminous but obscure...
and other vitamins/supps should be investigated when ill ... or small preventive doses can be used, but I suggest careful self education...
and there are differences in vit c, too, but the "natural and bio-flavonoid" meme is marketing with no scientific backing (as far as I could glean),
as vit c IS L-ascorbic acid and that is what most animals make and is what our human bodies would make from glucose if we didn't have a
mutation/defect.... and the common memes about not being able to absorb large amounts is wrong.
And true, most vit c is now made in China from gmo corn, but the real problem is the end product... it doesn't matter what it's derived from as long
as the end molecule is correct... the problem is that some v-c seems not to be well made and also, other, cheaper forms of the ascorbic acid is
used... rumor has it that the "D" form is cheaper and easier to make but is not active as vit c, but is used in many "cheaper" products that just list
"ascorbic acid." So look for an "L" in front of the ascorbic acid.
Vit e, too, should be "natural." Other vitamins and supplements are likely not as needed if one takes care of themselves and has a very healthy diet
and some people are just bonkers about the amount of supplements they take... but I gotta admit the folks I know who take some supplements are
generally healthier... so? And things like heart disease seems linked to non-acute scurvy (vit c deficiency).
I got schooled at www.vitamincfoundation.org ... a cheesy, dated looking site, but is has info with footnotes! They seem to try to keep it scientific
there... the discussion forum is full of wonks and gets deep.
