Nutritional Support for the Thyroid

Thyroid hormones are manufactured from iodine and tyrosine. With the advent of iodized salt the incidents of iodine deficiency has been greatly reduced in the United States. It has been estimated that 25 – 40% of the general adult population suffers from moderate to severe hypothyroidism. This may be due to the poor nutrient value in the foods eaten, or eating foods that block the synthesis of thyroid hormone. Tyrosine, which is synthesized in the body from the amino acid phenylalanine, is a precursor of thyroid hormones. Receiving sufficient amounts of tyrosine from the standard American diet is very difficult, thus supplementation is usually indicated.


The thyroid is a small butterfly-shaped gland with a sizeable role in the body. Its primary function is the production of essential thyroid hormones thyroxine (T4) and triiodothyronine (T3). T4 is converted to T3 by the body. Between them, T3 is the more potent, biologically active hormone. It regulates the metabolic rate within cells and affects fundamental functions throughout the body. Thyroid hormone production depends on the presence of iodine and the amino acid L-tyrosine in adequate amounts. T4 contains tyrosine and four iodine molecules, while T3 contains tyrosine and three iodine molecules. Production of thyroid hormones can be disrupted by several factors in the environment, including heavy metals, pesticides, hormonal fluctuations, antibiotic residues, chemicals and lack of nutrients required for thyroid hormone synthesis.

The thyroid gland interacts with the liver, kidneys, hypothalamus, pituitary, and adrenal glands. These coordinate the body’s response to stress and its quest for homeostasis.

Thyroid hormone activates over 100 enzymes in the body, exerting a significant effect on growth and metabolic rate. The metabolic rate reflects the body’s transformation of nutrients into energy. Thyroid hormone, and its influence on metabolic rate, plays a fundamental role in appetite, weight maintenance, energy levels and mood, gastrointestinal regularity, tolerance to temperature changes, and healthy hair and nails.
