Micronutrients & recovery
Selenium supplementation (200 mcg/day) reduces the incidence of prostate, colon, and lung cancers in high-risk populations.
Consider 200 mcg of selenium daily if you are at high risk for certain cancers, as evidence suggests it may reduce incidence. However, consult a healthcare provider due to selenium's narrow safety window.
ModerateSupportsMEDIUM confidence
In a recent study involving 1312 patients supplemented with 200 mg Se daily, the incidence of prostate, colon and lung cancers was decreased by 63, 58, and 46% respectively.
Why this rating
The paper cites a specific RCT (Clark et al.) but notes the mechanism is unknown and the study is older (1996).
