Why Electrolyte Replenishment Matters During Exercise
You sweat. You lose electrolytes.
When you’re active, your body cools itself by sweating — and in doing so, you lose essential minerals that help power muscles, maintain fluid balance, and prevent cramps.
On average, athletes lose:
🏃♂️ 0.5 to 1.0 liters of sweat per hour

What's In That Sweat?
Sweat isn’t just water — it contains sodium, chloride, and potassium. While sodium gets most of the attention, potassium plays a critical role in muscle function and cellular hydration.
💧 Each liter of sweat contains 200–300 mg of potassium
