Glucomannan is a water-soluble dietary fiber derived from the root of the konjac plant, known for its remarkable ability to absorb water and form a viscous gel in the digestive tract. Although often grouped with amino acids and compounds in supplement categories, it is technically a polysaccharide that has been used in traditional Asian cuisine and medicine for centuries. Research suggests that glucomannan may support weight management by promoting a feeling of fullness, while studies indicate it may also help maintain healthy cholesterol levels and support blood sugar regulation by slowing the absorption of sugars and fats in the gut.
