Your thyroid gland needs iodine to make thyroxine, a hormone your body uses for several daily functions. Many people experience low-iodine thyroid issues. These can include low appetite, mood and weight changes, and more. Thyroid Support offers comprehensive, out-of-the-box nourishment for the thyroid gland, including l-tyrosine, vitamin B6 and kelp. Nature’s Sunshine kelp, is wild-harvested in the North Atlantic Ocean by skilled reapers who use small paddleboats and special rakes to sustainably harvest the kelp and protect its natural habitat.
