Thyroid health is very important since the thyroid gland is a key component in the body's metabolic rate control mechanisms. Like any gland, the thyroid can damaged. This is important because more and more people are being diagnosed with autoimmune thyroid disease, or Hashimoto’s thyroiditis. The thyroid gland relies on several nutrients to help it repair from damage from chemical endocrine disruptors. Vitamin C and bioflavonoids (quercetin) intake can help support thyroid health. The thyroid requires iodine and tyrosine in order to construct the thyroid hormones and the mineral selenium is needed as part of an enzyme to transition T4 to the active for T3.
