Replenishes salt lost through sweat, helping maintain hydration and nerve function.
Sodium is the most abundant electrolyte lost in sweat during physical activity. It's essential for regulating blood pressure, fluid volume, and nerve function. Sodium chloride helps the body retain water, making it critical for hydration during workouts or prolonged exposure to heat. Without adequate sodium, rehydration is incomplete — no matter how much water you drink. It's also vital for muscle contractions and preventing hyponatremia (low blood sodium).
