Our Thyroid Support supplement is formulated to cleanse & revitalize healthy thyroid activity. Thyroid support is a unique iodine free formula. The thyroid gland is a butterfly-shaped gland that lies across the trachea at the base of the throat. One of the largest endocrine (hormone secreting) glands in the body the thyroid gland produces and secretes thyroid hormones, mostly T4 (inactive) and small amounts of T3 (active). When needed T4 is typically converted in the liver, kidney and other tissue to active T3. The primary action of thyroid hormone is to raise the body’s metabolic rate-that is, to increase the rate of oxygen consumption and energy expenditure. Thyroid hormones are also essential for normal growth and development in children, interacts with other hormones to modulate carbohydrate, fat and protein metabolism, and controls other important biological functions. Thyroid Support is a synergistic combination of nutrients and herbs designed to help support thyroid hormone production, activation and function, all of which are needed for normal, healthy thyroid function.
