A soluble dietary fiber extracted from the root of the konjac plant. It absorbs water and forms a viscous gel in the digestive tract.
Why it’s used
Taken to support feelings of fullness, healthy cholesterol levels, and weight management alongside diet changes.
What the evidence is for
supporting weight loss when combined with an energy-restricted diet.
What the evidence says
The European Food Safety Authority has recognized a link between glucomannan intake and reduced body weight in the context of an energy-restricted diet, at a specific studied dose. Evidence for cholesterol effects is more mixed, and results for weight loss without dietary changes are less consistent.
Dose studied
3–3 g — EFSA-recognized daily intake studied for weight loss in the context of an energy-restricted diet.
Context
The EFSA-recognized effect is based on an intake of 3 grams per day, taken in three doses before meals with water, alongside a reduced-calorie diet — a specific protocol rather than general supplementation.
