Re: What is the best form of vitamin A to take?

[Guest guest]

i take the vitamin a from douglas labs - order it from amazon, or there's

somewhere in netherlands that sell it, i think

personally, i don't bother about the contamination of fish oils in this product

- it's the least of my worries right now!

most of the vit As seem to be in soy bean oil so guessing the amount of vitamin

a/fish oil is minute in these capsules

Hi all,

Zinc and A are linked closely - not enough zinc - you cannot convert A - not enough A - you are unable to metabolise your protein efficiently.

So you need to make sure your Zinc levels are adequate too.

Hope this helps

Best wishes

Hi Debbie,

Beta Carotene is necessary for your body/thyroid gland function in order to produce thyroid hormone. (I assume you still have some function?)

This is a symbiotic relationship; since as the thyroid gland proudces its hormone T3 is necessary for the conversion of Beta Carotene to Vitamin A!! clever isnt it? If it all works well that is.

You can tell if your body is having a job converting carotenes as you will notice a yellow tinge on your palm and soles of your feet. This is a subtle sign of hypothyrodism for the reasons described above.

Vitamin A also has a role in immune function.

When one of the thyroid hromones binds to cell receptors a number of biochemical reactions are triggered. These carry messages to the cell nucleus and the cell nucleus is activated, whereby it produces proteins that carry out thyroid functions such as increasing metabolic rate and producing energy/heat. Vitamin A influences how well thyroid hormone receptors in the nucleus of the cell function.

If your thyroid hormone levels are improved (through supplementation) and further if you are able to convert t4 to T3 (or take T3 supplement), then this should resolve.

There's more info on Vitamin A here:

Dr. Langer's book titled Solved: the Riddle of Illness, turned out to be one of

the best sources I have found to date concerning the question of carotene

conversion and vitamin A. He devotes an entire chapter on nutrition for thyroid

illness which emphasizes the danger of extreme vegetarian diets and the problem

of carotene conversion and vitamin A deficiency.

Dr. Langer has this to say;

" I see too many risks in the Spartan vegetarian diet.....carotene, the vitamin

A precursor is not easily translated into vitamin A....In

hypothyroids and diabetics, this ability is nearly completely

blocked. " (p.31)

Thanks and Sally for your help on this. I will look further into the T4

to T3 conversion as I do indeed have the yellow-orangey soles on my feet and

sometimes hands. Used to cause my family much amusement. And I will look into

getting preformed vitamin a. Many thanks. Debbie
