Selenium is a trace mineral needed in microgram amounts. Purezen uses selenomethionine, the form found in food, which the body absorbs more readily than inorganic selenium salts.
The thyroid holds more selenium per gram than any other organ, and the mineral is needed for normal thyroid hormone activity. That is why it sits in ThyroFix with iodine and L-tyrosine.
Selenium supports normal immune function and the body's own antioxidant enzymes. That second role is why it appears in OxiShield and HerBalance as well as ThyroFix.
ThyroFix, OxiShield and HerBalance each give 40 mcg of selenium per 2-capsule serving, which is 100% of the daily requirement. It comes from selenomethionine.
ThyroFix, OxiShield and HerBalance: one capsule after each of two meals. If you take thyroid medication, keep a gap of 4 hours between it and ThyroFix.
Each of these already gives the full daily requirement, so do not take two of them together without speaking to your doctor.
Every batch comes with a Certificate of Analysis, a lab report confirming what is inside. The finished product is also tested at a NABL-accredited lab for heavy metals and microbes. See the current batch report on the ThyroFix page.
Speak to your doctor first if you are pregnant or nursing, take thyroid or other regular medication, or already take a selenium or multivitamin supplement. Selenium has a narrow safe range, so do not exceed the recommended dose. Keep out of reach of children.
