Research Summary

Copper is essential for cytochrome c oxidase and other oxidative enzymes critical to cellular energy production. Clinical research supports its role in maintaining bone density, cardiovascular health, and cognitive function. However, excessive supplementation is associated with toxicity; most people obtain adequate copper from dietary sources including shellfish, nuts, and whole grains.
