Many people use glucomannan incorrectly. Learn how a quality formula takes the guesswork out of dosing.
What Is Glucomannan?
Glucomannan is a water-soluble dietary fiber derived from the root of the Amorphophallus konjac plant, native to Southeast Asia.
What makes it special?
- Absorbs up to 50x its weight in water, forming a thick gel in your gut
- Contains around 40% soluble fiber by dry weight
- Virtually calorie-free (only 5 calories per gram)
- Naturally vegan and gluten-free
This gel-forming action is central to its health benefits, especially for appetite control, blood sugar moderation, and gut health.
