Potassium

Potassium is an essential electrolyte that regulates muscle contraction, nerve signaling, hydration, and cellular energy balance. Even slight imbalances can affect performance, cramping, recovery, or heart rhythm. Low potassium is super common—especially in low-carb, low-sodium, high-stress, or high-sweat lifestyles. High levels are rare but serious and usually linked to kidney issues.
