Nuun Hydration’s flagship sports drink product is packed with complete electrolytes and made with clean ingredients that replace what is lost when you sweat during exercise. Finish your workout strong, hydrated and replenished. Each tube contains 10 effervescent tablets. Simply drop a tablet into 16oz of water to make a healthy sports drink. Each tablet delivers 300 mg Sodium / 150 mg Potassium / 25 mg Magnesium / 13 mg Calcium/ 40 mg Chloride. Electrolytes help maintain fluid balance, prevent cramping, and aid in efficient muscle performance. Nuun is good for your health (low calorie, low carb, low sugar, no artificial flavors or colors), and good for the planet - one tube prevents the need for ten 16-oz plastic bottles from single-use sport drinks. Last year, Nuun saved over 100 million single use plastic bottles from adding to plastic landfill masses! At Nuun,
