Glucomannan is a natural dietary fiber derived from the root of the konjac plant. It is known for its ability to absorb water and expand in the stomach, which can help promote a feeling of fullness. This property makes it popular as a weight loss supplement, as it may reduce overall calorie intake. In addition to weight management, glucomannan is also used to support digestive health. It can help regulate bowel movements and may assist in managing cholesterol levels. As a soluble fiber, it dissolves in water and can be found in various forms, including capsules, powders, and noodles.
