Iodine provides substrate for formation of T4, while L-tyrosine provides substrate for T4 and T3 formation. Animal studies indicate the Ayurvedic botanical ashwagandha can increase T4 concentrations.
Several nutrients are necessary for peripheral conversion. The minerals selenium, zinc, and copper are cofactors for the enzyme iodothyronine iodinase that is necessary for conversion of T4 to T3. A vitamin B12 deficiency also appears to interfere with activity of thyroid hormones in
peripheral tissues. Peripheral conversion of T4 to T3 can be inhibited by heavy metal toxicity and lipid peroxidation; the antioxidant vitamins C and E can prevent this inhibition.
