Selenium: Thyroid Function, Antioxidant Enzymes, Cancer Prevention Evidence, and Toxicity Risk
Selenium is an essential trace mineral and key component of glutathione peroxidase and selenoprotein P. It has the strongest evidence base in thyroid autoimmunity (Hashimoto's) and antioxidant enzyme function. The SELECT trial found no cancer prevention benefit from selenium in replete populations — and excess is toxic.

Biomarker Testing Before Supplementing: B12, Vitamin D, Homocysteine, Ferritin, and CRP
Supplementing without baseline testing is guesswork. Vitamin D, B12, folate, ferritin, homocysteine, and hs-CRP are the most actionable starting points. This guide explains what each test reveals, what ranges mean, and which supplements to prioritize based on results.
