Thyroid Gland: Function and Dysfunction The thyroid gland is a butterfly shaped gland that is a key part of the endocrine system. It is of paramount importance and plays a vital role in the metabolism, growth, and maturation of the human body. It assists in the regulation of many physiological functions by releasing a steady stream of hormones into the bloodstream that have dynamic effects on their target tissues. Every cell in the human body requires thyroid hormone for proper function. Dysregulation of the thyroid gland, therefore, has systemic effects of varying degrees of severity. Hormones secreted by the thyroid gland interact with all of the other hormones throughout the body including, insulin, cortisol, and sex hormones like estrogen, progesterone, and testosterone. Thyroid impairment is a complex issue with many variables. Such variables include estrogen dominance, endrocrine-disrupting chemicals (such as mercury, lead, phthalates, bisphenol-A), and exposure to the halogen/halide family (such as bromine, chlorine, and fluoride). Essential Components of Thyroid Support and Recovery Iodine is key to a healthy thyroid and efficient metabolism. The major hormones secreted by the thyroid gland all have iodine molecules attached. Bladderwrack and Kelp are excellent, natural sources of iodine. Herbal Support to Optimize Thyroid Function Modulation of the body’s stress response is key in overall health and wellness. In today’s world, we have more stress than we can effectively, and efficiently, manage. This creates a breakdown in our body’s ability to manage stress. Ultimately, this results in adrenal system exhaustion/fatigue, which, in turn, has dramatic effects on thyroid function.
