Multi-purpose plant-based dietary fiber. What is glucomannan? Glucomannan is a soluble and fermentable dietary fiber from the konjac root plant. Its chemical structure is similar to that of galactomannan (from guar gum) and comprises a polysaccharide chain of glucose and mannose. Glucomannan can absorb up to 200 times its weight in water and forms a thick gel-like mass that has been shown to be approximately five times greater than that of guar gum. . How does glucomannan support health? As a water-soluble fiber glucomannan is appropriate for the relief of occasional constipation.*. The unique bulk-forming property of glucomannan makes it a top-performing fiber specifically suited for providing a feeling of satiety (fullness) and promoting healthy weight loss.*. Glucomannan may be used as part of your diet to help maintain a healthy blood sugar level.*. Promotes healthy blood lipid metabolism and helps maintain cholesterol levels that are already within the normal range.*. Why choose NSI Glucomannan? Has no unpleasant smell or taste. Has high absorption properties meaning it can be taken in much smaller quantities than other fibers like pectin or guar gum. About NSI.
