Aids in cleansing the digestive tract and supports digestive health by helping to eliminate waste. AdvoCare Fiber is rich in the fibers your body needs to support a healthy GI tract. Each serving provides 10 grams of dietary fiber, which can help you reach your daily fiber goal. Furthermore, each serving provides a combination of soluble and insoluble fiber. Soluble fiber absorbs water in your stomach and intestines, which provides a feeling of fullness that can help manage your appetite. Insoluble fiber does not absorb water, but rather moves quickly through your system, cleansing the digestive tract and eliminating waste as it goes.
