Why Selenium for General Health
For general health support, Selenium is a supporting ingredient backed by research. Essential component of selenoproteins including glutathione peroxidase (antioxidant defense) and deiodinases (thyroid hormone activation). Selenomethionine is the most bioavailable supplemental form, while sodium selenite is inorganic and less efficiently absorbed.
What dose to look for
Clinical studies typically use 100–200 mcg of selenium. Common supplement dose; UL is 400 mcg/day. Supplements that fall short of this threshold are unlikely to match what clinical trials achieved.
What form to look for
Avoid sodium selenite — inorganic, lower retention. For best results, choose selenomethionine.
