The Claim
There is a belief that increasing copper intake through supplements can lower the risk of heart disease due to its role in maintaining healthy blood vessels.
Origin
This idea comes from observational studies linking copper deficiency with cardiovascular issues, and has been promoted by some health blogs and supplement sellers.
What Science Says
Observational studies suggest a correlation between low copper status and heart disease, but causation has not been established. A systematic review on micronutrients and cardiovascular health found insufficient evidence supporting copper supplementation for heart disease prevention in healthy individuals. Adequate copper from food appears sufficient for most people.
Verdict
Partially True
