Glucomannan is a water-soluble polysaccharide that is considered a dietary fiber. Glucomannan fiber has a extraordinarily high water holding capacity, forming highly viscous solutions when dissolved in water. It has the highest molecular weight and viscosity of any known dietary fiber. This supplement has studied in the treatment of obesity due to the satiety sensation that it produces; as a remedy for constipation, because it increases the feces volume; as a blood cholesterol lowering agent, interfering in the transport of cholesterol and of bile acids and as blood sugar lowering supplement for those with diabetes. The use of a Glucomannan supplement delays gastric emptying and slows glucose delivery to the intestinal mucosa. In addition, because Glucomannan helps to promote satiety (feeling of fullness), it can be an effective addition to a weight management plan that includes a healthy diet and exercise programHow does Glucomannan work?Glucomannan might work in the stomach and intestines by absorbing water to form a bulky fiber which treats constipation. It may also slow the absorption of sugar and cholesterol from the gut, helping to control sugar levels in diabetes, and reducing cholesterol levels.
