Fibersure is a dietary fiber supplement that was introduced by Proctor & Gamble in 2006. Colorless and tasteless, Fibersure could easily be mixed in liquids or incorporated into baking and other recipes, providing users with a daily dose of fiber. Fibersure contained just one ingredient, inulin, a vegetable fiber. Fibersure may still be available for purchase at some locations, but as of 2010 Proctor & Gamble no longer markets the product under that name.The company changed the name to metamucil clear and Natural. The product's only ingredient, inulin, remains the same.


Inulin is a vegetable fiber made from chicory root. Chicory is a plant that grows wild throughout North America. According to Georgetown University, chicory leaves can be used as a vegetable or salad green. Its root is sometimes ground and used as a coffee substitute or additive. For centuries, chicory root has been used for medicinal purposes to aid in digestion and treat skin ailments, gout, jaundice and inflammation.

Types of Fiber

There are two types of fiber, soluble and insoluble. Inulin is a soluble fiber. A teaspoon serving of Fibersure contains 5 g of fiber. Soluble fiber dissolves in water and forms a gel during digestion, which slows the digestive process. Insoluble fiber makes the stool bulkier, speeding the digestive process. The body is unable to digest fiber. So it is expelled from your body largely intact. Insoluble fiber contributes to healthy bowel movements. Soluble fiber helps the body maintain healthy blood cholesterol levels, lowers your risk for heart disease and controls blood glucose levels.

Dietary Fiber Sources

Although a fiber supplement is a healthy alternative, the best sources of fiber are those found in the food you eat. Peas, beans, barley, lentils, nuts and fruit are sources of soluble fiber. Insoluble fiber is found in vegetables, bran and whole grains such as whole-wheat flour, wheat germ, brown rice, and buckwheat. A high-fiber diet helps you maintain a healthy weight, healthy bowels and healthy cholesterol levels. According to the Harvard School of Public Health, adult men should consume more than 30 g of fiber daily and adult women should aim for more than 20 g of fiber daily.
