Overview

NOW Foods Glucomannan provides 575mg per capsule of konjac root fiber, a soluble fiber that absorbs up to 50 times its weight in water. When taken before meals with water, glucomannan expands in the stomach to promote feelings of fullness and reduce caloric intake. It's one of the few weight management supplements with actual clinical evidence — the European Food Safety Authority (EFSA) has approved the health claim that glucomannan contributes to weight loss when taken before meals. It also supports healthy cholesterol and blood sugar levels.
