SUPPORTS THYROID HEALTH: Iodine plays an important role in the body as a key component of thyroid hormones, including thyroxine (T4) and triiodothyronine (T3).
PROMOTES ENERGY: Getting adequate amounts of iodine helps support the thyroid, which, when working optimally, promotes mental clarity and focus, and a boost in energy levels.
RESTORE HEALTH-PROMOTING TRACE ELEMENT: Iodine deficiency may be more common due to a decreased use of iodized salt. It also exists among vegetarians and vegans due to foods of plant origins being less rich in iodine than animal-derived foods. Also, athletes and people engaged in rigorous physical activity are at risk of depleting this trace mineral through profuse sweating.
