Nutrigold Glucomannan GOLD, Konjac Root Fiber for Weight-loss, 750mg, 120 Vegetarian Capsules
Glucomannan is a water-soluble polysaccharide extracted from the tubers (roots) of Konjac, which is cultivated as food in Japan and Indonesia. Because human digestive enzymes cannot break down this polysaccharide, it passes through the body largely intact, which is the reason it is classified a dietary fiber. Glucomannan is hygroscopic and the dry powder swells into bulky fiber because of its ability to absorb up to 50 times its weight while in water. Glucomannan's principal use is as a bulking agent to promote the feeling of "fullness" or "satiety", thereby helping to manage food intake.
