The Claim
It is commonly believed that copper supplementation can enhance immune function, making people less susceptible to infections.
Origin
This belief likely stems from copper's known role in enzymatic reactions that are critical for immune function, as well as marketing claims.
What Science Says
Copper is indeed essential for immune function, but the typical diet provides sufficient amounts. A meta-analysis of nutrient deficiencies and immune health found that only severe copper deficiency negatively impacts immunity. There is no substantial evidence that additional copper intake boosts immune function in people with normal copper levels.
Verdict
Misleading
