Selenium is a trace essential element that is incorporated into selenoproteins. There are at least 25 known selenoproteins in the human body, their primary roles being antioxidant enzymes such as glutathione peroxidase and thyroid deiodinases that convert thyroxine (T4) to active thyroid hormone (T3). Deficiencies in selenium can be detrimental to health, while selenium excess can be just as…

Defeat the Enemies of Healthy Thyroid Function

The thyroid gland, while small in size, is one of the most significant endocrine glands. It's also key to how quickly the body uses energy, makes proteins and it controls how sensitive the body is to other hormones. According to the American Association of Clinical Endocrinologists (AACE), thyroid disease is more common than diabetes or heart disease and affects as many as 30 million Americans.…
