How long does konjac root glucomannan stay in your stomach?
It hydrates and slows gastric emptying but generally leaves the stomach in about 2–6 hours, depending on the meal and dose, then moves to the intestines where it’s fermented. Always take it with plenty of water to reduce choking or blockage risk.
