It's generally recommended that adults consume 25 to 35 grams of fiber per day, but most Americans only get about half that amount. Fiber's value to athletes and health conscious individuals is centered on its important role in digestive support. If you're not consuming enough fruits and vegetables to meet your fiber needs, adding a teaspoon of Fitness Fiber to beverages, protein shakes, oatmeal or bowl of cereal gets you 5 grams closer to meeting your goal – with only 10 additional calories.
