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.*
