Potassium

minerals

Potassium is an essential mineral and electrolyte critical for maintaining healthy blood pressure, heart function, and muscle contractions. It works synergistically with sodium to regulate fluid balance and nerve signal transmission throughout the body. Adequate potassium intake is vital for cardiovascular health and overall physiological function.

Research Summary

Extensive clinical evidence supports potassium's role in blood pressure regulation and cardiovascular disease prevention. Multiple large-scale studies, including the DASH diet research, demonstrate that adequate potassium intake significantly reduces hypertension and stroke risk. However, supplementation should be medically supervised, particularly for individuals with kidney disease or those taking medications affecting potassium levels.
