Selenoprotein biology / thyroid-hormone metabolism
Selenium contributes to selenoproteins involved in thyroid hormone metabolism and cellular protection. Its biological role does not establish that supplements prevent cancer.
Established essential nutrient role; selected prevention trials do not support general cancer prevention with supplementation.
Baseline selenium status matters. Laboratory antioxidant effects are not evidence of cancer prevention or longer life.

Chronic excess can cause selenosis, including brittle nails, hair loss, gastrointestinal symptoms and neurological problems.
Known high selenium exposure or signs of toxicity need assessment rather than additional supplementation.
Cancer therapy and concurrent supplements should be reviewed with the care team; interaction information is not exhaustive.
