Fiber Clean provides an easy way to boost your dietary fiber intake. The fiber comes from psyllium husks, a popular source of dietary supplement fiber. Each of the 15,000 gel-coated seeds on the psyllium plant is high in fiber. The mucilage, the main substance of the seed, swells when it comes in contact with water. This bulking effect helps to push the material through the digestive tract and also helps to lubricate it. Fiber Clean has 500 mg of psyllium husk powder to conveniently boost your dietary fiber intake.
