Twelve electrolyte-replacing drink tablets contained in each tube. Great for paddling, hiking, travel and any endurance activity. Use 1 tablet per 500-650 ml of water.
Nuun's special formulation of electrolytes helps increase the amount of water that's absorbed into the blood stream. That means more of the water you drink is actually used to hydrate you instead of being eliminated because the electrolyte balance wasn't right. Nuun is not energy. Nuun is just for hydration.
