Glucomannan is a soluble type of dietary fiber extracted from the roots of the konjac plant. It is often used as a dietary supplement and is known for its potentially healthy effects.
The glucomannan plant, scientifically known as Amorphophallus konjac, is a perennial plant native mainly to the tropical areas of East Asia, particularly Japan and China.
The dietary fiber contained in konjac root can support health and accelerate weight loss. Cravings are reduced and the feeling of satiety can be sustained for a long time.
