Hypothyroid persons don't do much with beta carotene form of

Vit A, but need the form of Vit A derived from fish oils.

I have found this to be true from my own experience as well

over the last 20 yrs or so.

Most supplements, especially multi's, switched to beta carotene

Vit A about 15-20 yrs ago. You can still get non-beta-carotene

form of Vit A in cod liver oil (that also has Vit D) or in

gelatin capsules with Vit A only (very inexpensive at the

grocery store, drug store, or health food store). There is also

a genre of Vit A called " dry " or " water soluable " that is not

beta-carotene, but it's not oily either - Twinlab makes this,

and it's very well absorbed by thyroid patients. Metagenics

also makes a liquid water soluable Vit A in a dropper bottle,

for high therapeutic doses intended to be supervised by a health

professional.

If iodine were being taken in order to give the

thyroid nutrition to make thyroid hormone,

then Vit A in a non-beta-carotene form would be

needed as well *for the hypothyroid person*.

I don't think this is true of normals, who would

theoretically be getting all the Vit A they need from

green leafy, yellow and orange vegetables and fruits.

Both retinoic acid (derived from Vit A) and thyroid hormone

are important in proper cell differentiation.

Know anything about people not being able to tolerate cod liver oil? It's the

one supplement

that I have problems with. Every time I try to take it, it causes heart palps.

I don't have any

problems with beta carotene. Does it with or without taking iodine also.

I don't tolerate cod liver oil, ever, and have a food sensitivity to

cod. I use northern Atlantic salmon oil for my omegas and halibut

liver oil for my A and D.

The Hypothyroid people doing worse on vegetable sources of A than

animal sources fits perfectly into the ANS dominance idea. Those who

are parasympathetic dominant, have weaker thyroids and thrive on

animal proteins and a higher fat diet.

Hyperthyroid people would be more likely to have a dominant

sympathetic nervous system and do better on veggie sources of vitamin A.

As a young child when I was recovering from TB, I used to steal and

eat 5 or 6 of the very potent Halibut liver oil pills at a time. my

parents tried to keep them away from me but I was determined. I now

believe that I needed the very high dosage of A and D to finish

healing from a life threatening infection.

I have a very strong dominance of my parasympathetic ANS.
