The American College of Sports Medicine recommends that athletes replace sweat losses with fluids during activity. But, because individual sweat rates vary so much, it's hard to recommend a specific amount of sodium or other electrolytes. They do say that an athlete with an average sweat rate of one liter per hour can lose approximately 2 to 10 grams of sodium in a 2-hour practice. In order to avoid hyponatremia, replacing lost sodium is also recommended. They encourage athletes to recognize their individual needs based on their own diet and sweat losses.
Nuun provides 700 mg of sodium per liter so it will meet this need for the average exerciser over a long workout.
Because nuun doesn't contain any carbohydrate, which slows the rate of stomach emptying, it is absorbed faster into the body than sports drinks with added carbohydrate.
Keep in mind that people who are active for more than 90 minutes should also replace depleted carbohydrates (glycogen stores). So taking nuun alone won't meet this need. And if you are on a low-sodium diet, check with your physician before adding nuun to your diet.
