ns - "Vitamin B" turned out to be a grab-bag of eight different compounds, which is why you now have vitamin B-12
same way no matter how they were made.
in the vitamin you are taking, but that isn't a natural/unnatural distincti on - "natural products" are, if anything, more prone to unfortunate impurit ies.
tamin B-12?
ncludes retinol, retinal, retinoic acid, and several provitamin A carotenoi ds (most notably beta-carotene)."
You are a half-wit. Retinol is Vitamin A-1.
Retinal is a visual pigment. Retinoic acid is generated in the body from re tinol but isn't a vitamin because you can't absorb it directly.
corbate and calcium ascorbate.[1] Vitamin C molecules can also be bound to the fatty acid palmitate, creating ascorbyl palmitate, or else incorporated into liposomes.[83]"
Ascorbic acid and it's salts all end up as the same molecule in the body, d oing the same job.
Your body doesn't give stuff how it gets it's ascorbic acid, so worrying ab out which salt you take is a waste of time.
f this, and anyone that doesn't but has a brain cell can do the reading.
Anybody who knows even a bit about the chemistry involved knows that you ar e an ignorant sucker who has been sold a bill of goods. I sat through the l ectures and got the degree, so I know quite a bit about chemistry. Having p arents who both had university degrees in chemistry got me off to a good st art, and left me well-primed on how to be rude about half-baked ideas (of t he kind I came up with when I was twelve).
ficial only. It is simply incorrect to state that artificial and natural vi tamins are the exact same compounds.
rticular configuration of atoms - once you've got it you've got something w ith the same chemical activity. If you don't understand that, you've failed to understand what chemistry is about.
It's a pity that it went over your head, but not exactly surprising.

hat we don't know the full list of human requirements. Certainly looking at RDAs doesn't get you there.

Not the answer that NT wanted, which doesn't make it wrong in any objective sense.
en on the nutrients everyone agrees are essential. Also the RDA doesn't eve n attempt to provide optimum intake levels.

s that you don't need as much vitamin D in sunny areas as you do where it's dark for months on end. There are many other interactions between nutrient intake & other factors.
in Sydney, which is pretty sunny, and still have to take twice the recomme nded dose of vitamin D pills to keep my blood serum levels high enough to m ake my GP happy.
Which are pretty silly. Not as silly as no recommendations at all, but they do need to be treated as broad-brush generalisations.

One of NT pet idiocies has been dissed.

NT doesn't like be being reviled as a gullible nutcase. If he did enough ca reful reading to learn about the subjects he pontificates about he'd post l ess nonsense and get reviled less often.
Fat chance. Pontificating about chemistry to somebody who got a Ph.D. in th e subject isn't a great way of making yourself look clever.
Win Hill started a Ph.D. in chemical physics but probably had better superv ision than I had, and dropped it to move into electronics. I got the Ph.D. in Physical Chemistry before moving into electronics.
