The hormones thyroxine (T4) and  triiodothyronine (T3) are produced by the thyroid gland. These hormones are  essential to the proper development of cells in the body. Thyroid hormones  regulate the metabolism of proteins, fats, and carbohydrates, affecting how  these compounds produce energy. Individual thyroid hormones have important  functions in the body; for example, T4 supports cardiac output, heart rate,  respiratory rate, and basal metabolic rate (BMR). A low BMR may cause one to be  fatigued, chilly, and have trouble losing weight.

Thyrocsin provides supportive nutrients for a healthy thyroid gland. Not only  does Thyrocsin support healthy thyroid function, it also provides nutrients  necessary for conversion of T4 to T3 in the tissues outside the thyroid gland.

Iodine is necessary for formation of T4, while L-tyrosine is a necessary  component of both T4 and T3 formation. Animal studies indicate the Ayurvedic  botanical ashwagandha can increase T4 concentrations. Several nutrients are  also necessary for conversion of T4 to T3, including the minerals selenium,  zinc, and copper. Thyrocsin contains vitamin B12 because its insufficiency  appears to interfere with the activity of thyroid hormones. Conversion of T4 to  T3 can be inhibited by heavy metal toxicity and lipid peroxidation; the  antioxidant vitamins C and E can counterbalance this inhibition.

Thyroid hormones are involved with metabolism throughout the body. Thus, a  deficiency or excess of thyroid hormones can have far-reaching effects. High  cortisol levels can interfere with thyroid function, resulting in low T4 or  poor conversion of T4 to the active form, T3. Nutrients that support normal  levels of cortisol may be of benefit for this population.
