Glucomannan is a water-soluble dietary fiber that's derived from the Konjac root (Amorphophallus konjac). Because glucomannan is found in negligible amounts in food, supplementation is necessary.

Glucomannan is a dietary fiber that helps to increase stool bulk by absorbing water. This helps stool pass more easily through the colon, preventing unnecessary stress to the colon.

Because it is a fiber, glucomannan can assist with weight loss and healthy weight maintenance by expanding in the stomach and absorbing fats. Absorbed fats are eliminated from the body and do not undergo digestion, thus nullifying their caloric effect. Also, glucomannan occupies space in the stomach and provides feelings of fullness. You'll eat less when this happens, and this will direct your body to tap into body fat stores for energy. Simply, you'll have a better chance of burning fat and losing weight when you use glucomannan.

Glucomannan is a popular ingredient in nutritional weight-loss supplements because of its weight loss and insulin controlling abilities.
