Glucomannan is a type of fiber that is often used in many Asian health foods. It is also used in many weight loss pills. There is some evidence that glucomannan may be effective for type 2 diabetes, and preliminary studies suggest that it may help with constipation, high cholesterol, and obesity as well. Possible side effects include digestive symptoms (such as bloating and gas).
What Is Glucomannan?Glucomannan is a type of vegetable fiber that comes from the root of a plant known as konjac (Amorphophallus konjac, to be specific). This fiber is commonly used in Asian health foods, and many herbal supplements now contain glucomannan. In addition to its use in foods, the fiber is often used for the following purposes:
- To relieve constipation
- To lower cholesterol
- To aid in weight loss
- To lower blood sugar (in people with type 2 diabetes).
