Glucomannan is a water-soluble polysaccharide that is considered a dietary fiber. It is a hemicellulose component in the cell walls of some plant species. Glucomannan is a food additive used as an emulsifier and thickener. Products containing glucomannan, under a variety of brand names, are marketed as nutritional supplements with false claims they can help weight loss. The U.S. Food and Drug Administration (FDA) has not approved any product containing glucomannan for the treatment of any medical condition and its use may be harmful. They are also used to supplement animal feed for farmed animals.
