General: 1 g 3x/day (30-60 min before meals); Weight Management: 3-4 g/day with ample water

What are the side effects of Glucomannan?

Potential side effects include: Bloating and gas, Esophageal obstruction (if insufficient water), GI discomfort.

What is glucomannan and how may it support weight management?

Glucomannan is a water-soluble dietary fiber derived from the konjac root. It absorbs water and expands in the stomach, which may promote feelings of fullness. The European Food Safety Authority has authorized a health claim for glucomannan's contribution to weight loss in the context of an energy-restricted diet.

What dosage of glucomannan has been studied in clinical trials?

Clinical trials have typically used 1–3 grams of glucomannan per day, taken 15–30 minutes before meals with a full glass of water. The EFSA-authorized claim requires at least 3 grams daily in three doses of 1 gram each before meals.

What are the potential side effects of glucomannan?

Common side effects include bloating, flatulence, and loose stools. Glucomannan tablets may pose a choking hazard if they expand before reaching the stomach; capsule or powder forms with adequate water are preferred. It may reduce absorption of oral medications if taken simultaneously.

About

A water-soluble dietary fiber derived from konjac root that absorbs up to 50 times its weight in water, forming a viscous gel in the stomach. Glucomannan is the only dietary fiber with an EFSA-authorized health claim for supporting weight loss in the context of an energy-restricted diet.

How It Works

Water-soluble dietary fiber that absorbs up to 50 times its weight in water, forming a viscous gel in the stomach. This delays gastric emptying, prolongs satiety signals, and reduces postprandial glucose and insulin spikes. Also functions as a prebiotic, supporting beneficial gut bacteria that produce short-chain fatty acids (SCFAs).
