Fact 6. Iodine and Hashimoto’s: A Delicate Balance
Iodine, a trace element that plays a critical role in the production of thyroid hormones, has a complex relationship with Hashimoto’s disease. On one hand, adequate iodine is necessary for proper thyroid function. On the other hand, too much iodine can potentially worsen thyroid autoimmunity and even trigger Hashimoto’s in susceptible individuals.
Iodine’s role in thyroid health lies in its contribution to the production of thyroid hormones T3 and T4. Without enough iodine, the thyroid cannot produce these hormones in adequate amounts, leading to hypothyroidism.
But why does too much iodine pose a problem? When the body has more iodine than it needs, the excess iodine can cause the immune system to rev up and attack the thyroid gland. This is particularly problematic for people who already have a genetic predisposition for Hashimoto’s. (6)
