ThyroMedica Plus® features targeted nutrients and herbs that reinforce healthy thyroid function and facilitate the expression of thyroid hormone genes. Key ingredient such as L-Tyrosine, which serves as the foundation to nourish healthy levels of thyroxine. Iodine plays a key role in the synthesis of thyroid hormones. Riboflavin, flavin adenine dinucleotide (FAD), plays a role in energy production in the cell. Guggul and Ashwagandha may assist in the conversion of thyroxine to the more bioactive triiodothyronine (T4 to T3) and may stimulate the thyroid gland.* These ingredients may aid in maintaining healthy blood lipid levels. Rosemary has been added for its antioxidant properties and may assist in preventing free radical damage to thyroid tissue.
