Dietary folate deficiencies and drugs that interfere with folate metabolism, eg, methotrexate, an anti-carcinogenic agent that inhibits dihydrofolate reductase, and nitrous dioxide (N 2 O), an anesthetic gas that inhibits methionine synthase activity, lead to accumulations and cellular effluxes of homocysteine, causing increases in circulating homocysteine levels (Ueland and Refsum, 1989)
It was demonstrated that the application of antioxidants, i.e., Vitamin C, Vitamin E, and turmeric, greatly increased the circulating levels of T3 and T4, which could be caused by the direct participation of antioxidants on the thyroid gland or the activity of deiodinase enzyme (125)
