You sweat, Nuun Active Hydration replenishes! Nuun’s signature profile of 4 key electrolytes helps your body make the most of the water you’re drinking.

Each tube contains 12 effervescent tablets. Simply drop a tablet into 16oz of water to make Nuun. Each tablet delivers 360 mg Sodium / 100 mg Potassium / 25 mg Magnesium / 13 mg Calcium; electrolytes that help maintain fluid balance, prevent cramping, and aid in efficient muscle performance.

Nuun is good for your body (less than 1g of carbs, low calories, no added sugar, no artificial flavors or colors), and good for the earth - one tube prevents the need for twelve 16oz plastic bottles from sport drinks.

36:T57f,I discovered Nuun only recently while riding the 2011 edition of RAGBRAI. The Nuun folks had booth set up at the start town and were giving out sample drinks. I gave the flavors they had on hand a try and was pleasantly surprised by the subtle flavor. I picked up a few tubes for our ride across Iowa and used the product about every fourth or fifth bottle of water for the next 450 miles. The weather this summer was brutal, 95-105F every day with high humidity. I was well hydrated the whole time and never felt I was in trouble. I can't definitely say this was due to the Nuun, but I'm glad I used it.I tried several different flavors and have discovered that my favorite is definitely the Orange. I also tried the Lemon-Lime, Citrus Fruit, and Lemon Tea (w/caffeine). They were all good but the orange flavor wins hands down for me - I think it's the hint of ginger.The
