The Claim
Some people believe that selenium supplementation can reduce the risk of heart disease, based on its antioxidant properties that theoretically protect against oxidative damage linked to cardiovascular problems.
Origin
This belief comes from observational studies that suggested an association between higher selenium levels and lower heart disease risk.
What Science Says
While observational studies have shown an association, RCTs and meta-analyses do not consistently support a causal effect of selenium on reducing heart disease risk. The evidence is mixed, with some studies showing no significant impact on cardiovascular outcomes.
Verdict
Mostly False
