Why it works when salt water doesn't

Your body loses five electrolytes. Most brands replace one.

Dump in sodium alone and you still fade and cramp on a long chipper. EN engineers all five back in at 1,580 mg — the exact proportion you lose in sweat. Engineered to physiology, not a marketing label.
