The Active Ingredient Is: Glucomannan (konjac root fibre)

Glucomannan is a soluble fibre derived from the konjac root and is used to help support normal digestive function through its bulking effect in the gut.

This form comes from konjac root and forms a viscous gel in the stomach and intestines, contributing to regular bowel movements and overall fibre intake.

What Does Glucomannan Do?

Glucomannan absorbs water to form a gel, which bulks the contents of the stomach and slows gastric emptying, supporting feelings of fullness and portion control. It also can contribute to healthy cholesterol and blood sugar levels by affecting absorption, in line with EFSA guidance.

EFSA notes a cause-and-effect relationship for weight management when glucomannan is taken correctly, supporting its role in normal metabolism without implying disease outcomes.
