Thyroid Conversion Support is a specialized blend of nutrients and herbs designed to promote healthy biosynthesis of thyroid hormone, including the conversion of T4 to T3.* It contains these key nutrients: Vitamin A Vitamin A deficiency can lead to structural and functional changes of the thyroid gland, and it also acts as a free radical scavenger, reducing oxidative stress on the thyroid.* [41] Vitamin D3 Research has shown that low levels are associated with increased self-tissue response (meaning your body is more likely to launch an immune attack on itself), and it plays a role in immune system balance.* [42] Vitamin E May help protect thyroid cells/tissue and also supports the enzymatic conversion of T4 to T3 by scavenging damaging free radicals.* [43] Iodine While iodine deficiency can lead to hypothyroidism and poor T4 to T3 conversion, excess iodine has been implicated as a trigger for autoimmune thyroid diseases, so I consider it a narrow therapeutic index nutrient
