We are currently in the process of converting the selenium in our products to selenomethionine, a well-absorbed, well-researched, amino acid-bound selenium. The new batch of Thyrocsin just released contains 100 micrograms of selenium (as selenomethionine) in place of the selenium picolinate.
nutritional support for thyroid function*
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.*
