OptiFiber® Lean features Shimizu Propol® A propolmannan—a highly pure, natural soluble fiber from Amorphophallus konjac glucomannan. This advanced formula supports satiety, weight control, glucose and cholesterol metabolism, healthy bowel movements, and serves as a prebiotic for beneficial intestinal bacteria.*

Propol A's exceptional viscosity (100,000 mPa·s) and stability through the digestive tract create a gel-like substance that slows digestion, delays stomach emptying, and helps reduce the absorption of carbohydrates and fats.* Research demonstrates that glucomannan supplementation at 3-4 g daily significantly reduces weight and supports healthy body composition when combined with proper diet and exercise.* It also promotes regularity, increases beneficial bacterial populations, and supports overall digestive health.*

Available in 180 capsules.
