About

Glucomannan is a sugar made from the root of the konjac plant (Amorphophallus konjac). Glucommanan powder, capsules, and tablets are used as medicine.

Glucomannan is used for constipation, weight loss in adults and children, type 2 diabetes, blood sugar control, and lowering cholesterol.

In foods, glucomannan is used as a thickener or gelling agent. Glucommanan flour and powder are used in food.

Glucomannan might work in the stomach and intestines by absorbing water to form a bulky fiber which treats constipation. It may also slow the absorption of sugar and cholesterol from the gut, helping to control sugar levels in diabetes, and reducing cholesterol levels.
