If you have hypothyroidism, you may want to take cod liver oil. Here's why.
The thyroid needs three main nutrients:
1. Vitamin A
2. Iodine
3. Selenium
Iodine makes up the thyroid molecule. When we talk about T4 or T3, we're talking about the number of iodine molecules. Selenium is involved in an enzyme that allows the conversion from T4 to T3 (the active form of the thyroid hormone).
Vitamin A is involved in another hormone called thyroid-stimulating hormone, which is created from the pituitary and sent down to the thyroid. One way they diagnose a hypothyroid case is if the thyroid-stimulating hormone has increased. If you have a vitamin A deficiency, you likely have an increase in thyroid-stimulating hormone. This could increase the size of the thyroid and decrease the absorption of iodine.
I believe the best source of the active form of vitamin A (retinol) is cod liver oil.
