The Claim
Some athletes take copper supplements believing they can enhance physical performance due to copper's role in energy production and red blood cell formation.
Origin
This myth is perpetuated by some fitness and supplement industries, which capitalize on copper's biological roles.
What Science Says
While copper is necessary for energy metabolism and red blood cell production, studies have not shown performance enhancements from copper supplementation in athletes with adequate dietary intake. A review of trace mineral supplementation and athletic performance concluded that only deficiencies impact performance, and excess intake does not confer additional benefits.
Verdict
False
