Nuun is a portable Alka-Seltzer type tablet that is dissolved in water to replenish the body of important electrolytes. Nuun contains zero sugar and produces a hypotonic solution so your body absorbs it faster than water alone or sports drinks. This allows it to restore optimal water and electrolyte balance quickly and efficiently. It was designed just for hydration, not energy. Each tube contains 12 tablets, there are over 10 flavors to choose from and is easy to use. Just drop a tablet into 16 oz of water, let it dissolve then drink it.
Since being introduced to Nuun I now pass up the sugar-filled Gatorade and grab these tablets after a physical workout or to fill my Camelback for an outdoor activity.
