Thyroid Support has been developed for those with an underactive thyroid gland to offer a wholefood base multi-mineral supplement to support thyroid health. Thyroid Support contains the active nutrient kelp - the iodine content of kelp means it is of great benefit to thyroid metabolism particularly as iodine is one of the micronutrients known to be short in the diets of many. L-tyrosine is included as it is beneficial to have l-tyrosine and iodine ingested together in a form that can be immediately usable by the thyroid gland to promote the production of the thyroid hormones. Nature`s Own wholefood supplements are made from minerals that have been hydroponically-grown into a cruciferous vegetable (brassica) that is a member of the broccoli family of vegetables. The brassica base also contains zinc, copper, potassium, calcium and magnesium and acts as a food base to aid absorption of and metabolism of the nutrients. Gluten free,
