Potassium is an essential mineral and electrolyte that plays a critical role in muscle function, nerve conduction, and fluid balance. It is vital for maintaining proper muscle contractions and heart rhythm, especially during and after physical activity.
During exercise, potassium is lost through sweat, and inadequate levels can lead to muscle cramps, weakness, and impaired performance. For physically active individuals, maintaining potassium balance supports endurance, hydration, and recovery.
It works synergistically with sodium and magnesium to regulate cellular function and prevent dehydration-related issues.
