Potassium is an essential mineral for cardiovascular health that helps manage vascular tone and supports a healthy heart rhythm. Its inclusion in this protein isolate provides foundational support for circulatory wellness.

While providing quality nutrition, the contribution to heart health is secondary to its role in muscle protein synthesis. The potassium dose is modest and lacks the synergistic cofactors typical of specialized cardiovascular supplements.
