Re: Synthetic vitamin A is identical to vitamin A in liver?

I think I know what you're asking, however I'm not certain.

If you could restate that I'm pretty sure I can answer your question.

Thanks,

The article about Vitamin A on the Weston Price website makes the

point that Vitamin A is a bunch of differant isomers which come as

acids, aldehydes and esters, whereas synthetic Vitamin A comes in

only one form - all-trans retinol in ester form, usually palmitate.

However, apparantly the liver only stores Vitamin A in ester form and

for the most part (over 90%), as all-trans retinol. In which case

when you eat liver you'd basically be getting exactly the same thing

as synthetic Vitamin A: predominantly all-trans retinol in ester form.

If this is the case, how can consuming liver be any differant from

taking the synthetic version?

This is the same error that the FDA makes and the same error that

most of the civilized world makes when thinking of synthetic vs.

whole food vitamins/minerals/enzymes etc...

1) Synthetic vitamins including A are not identical to Naturally

occuring A. The only evidence you need to confirm this is Look a

Price's work and observations regarding food A consumption. And look

at studies like the one out of Finland where men given synthetic A

and E have far worse health and death rates than those who supplement

nothing.

2) Even if Synthentic vitamins were identical (and since this is not

true the rest of this point is pointless, however we'll make it

anyway) to Naturally occuring vitamins, the " matrix " in which the

natural vitamin occurs is what allows for appropriate, absorbtion,

breakdown and assimilation. ie. cofactors, enzymes, proteins, etc...

without these items a synthetic vitamin is no longer a vitamin it is

a toxin.

I hope this is of some help. This is just more mis-statements

regarding synthetic vs. naturally occuring vitamins. Wax lemons and

Real Lemons look the same, nearly identical however upon closer

scrutiny Real lemons are not the same as Wax lemons. These types of

research and researchers continue to befuddle the mind with their

total lack of common sense. So keep eating your liver like your

mother told you.

Dear

" Nearly all " is not the same as " all. " In food and in our bodies, vitamin A

is a complex of many isomers and they all work together. Sally
