Vitamin A and the thyroid
1979
Research is making the delineation between vitamins and hormones less specific. Studies of vitamin A and the thyroid indicate thyroid hyperactivity in vitamin A deficiency and higher vitamin needs in hyperthyroidism. High serum levels of thyroxine and thriiodothyronine were observed in vitamin A-deficient rats. Thyrotropin (TSH) content of pituitary and Thyrotropin Releasing Hormone (TRH) content of hypothalamus were also raised. It is postulated that in vitamin A deficiency the negative feedback regulation of the brain by thyroid hormone is disturbed.
