Biochemical Observations of Mitochondrial Dysfunction in Autism:
"A lack of selenium also affects the conversion of T4 thyroid hormone to T3. Stress reduces the conversion of T4 to the more active T3. Both cadmium and mercury inhibits the conversion of thyroxine (T4) to active T3. In a Chinese study, researchers found that selenium and vitamin E deficiency reduced blood levels of T3 by more than one-third. Vitamin E was thought to protect the T4/T3 conversion process. All myelination is controlled by T3. Free T3 regulates serotonin and melatonin metabolism. T3 controls serotonin uptake, binding to its receptors, so if there are serotonin problems, look to the thyroid. The active hormone T3 converts from T4, and to do this you need a specific ratio of zinc to copper of about 8:1. If you have had hair analysis and or fecal testing or blood tests you may know what your ratio is. If not, I would suggest finding out. Mercury (like in amalgam, and thimerosal in vaccines) will also cause hypothyroidism by interfering with selenoenzymes (Watanabe et al, 1999), and mercury competes and really messes up zinc absorption/utilization creating all kinds of effects throughout the body."
