Re: Is Selenium a must? Selenium or Selenemethione?

hi all,

Here's what we have: Studies have shown that if Iodine is low, selenium must also be kept low to prevent the hypothyroidism from becoming worse (from increased DI-I and T4 depletion, as explained above.) So if both minerals are low, then the person is hypo and gets a goiter, but the damage to the thyroid is kept to a minimum. More severe problems happen when either selenium or Iodine is high and the other is low. If selenium is high and Iodine low, then T4 to T3 to T2 conversion is accelerated without T4 being replenished, leading to a worsening of the hypoT. If iodine is high and selenium is low, then H2O2 (Hydrogen-Peroxid) is not degraded by GPX. Since H2O2 (Hydrogen-Peroxid) drives the thyroid hormone production, then the thyroid over-produces thyroid hormone (Grave's hyperthyroidism), the thyroid is damaged from the oxidation by the H2O2, and the end result is that the damaged thyroid ultimately decreases activity and hypothyroidism results (Hashimoto's thyroiditis). This could explain the observed progression of Grave's to Hashimoto's.
