Lean Fiber – Ultra-Pure Propol® A Propolmannan Fiber for Lasting Satiety, Healthy Weight Management, and Metabolic Balance

Lean Fiber delivers 3 grams of Shimizu Propol® A propolmannan per serving—an exceptionally pure, patented soluble fiber derived from Amorphophallus konjac through advanced proprietary processing. Unlike ordinary glucomannan, Propol® A is refined for superior viscosity and remarkable stability throughout the entire digestive tract, allowing it to gently expand in the stomach, slow gastric emptying, and deliver sustained benefits from mouth to colon.

Extensive clinical research on Propol® A demonstrates powerful effects on appetite control, healthy weight loss when combined with diet and exercise, balanced glucose and lipid metabolism, and comfortable bowel regularity. This prebiotic fiber also nourishes beneficial gut bacteria, supporting microbiome diversity and overall digestive wellness—making it an ideal choice for anyone seeking natural, evidence-backed support for metabolic health and sustainable weight goals.*

Key Benefits

Promotes Lasting Satiety and Supports Healthy Weight Management Propol® A’s unique viscosity creates gentle stomach expansion and slows digestion, helping you feel fuller longer, reduce between-meal cravings, and support calorie control as part of a balanced diet and active lifestyle.*

Supports Balanced Glucose and Lipid Metabolism By slowing carbohydrate absorption and binding dietary fats, this high-viscosity fiber helps maintain already-healthy blood sugar and cholesterol levels, contributing to metabolic wellness and cardiovascular health.*

Encourages Comfortable Bowel Regularity The stable, soluble nature of Propol® A adds gentle bulk and promotes soft, regular stools without the gas or urgency sometimes seen with lower-quality fibers—ideal for daily digestive comfort.*

Serves as a Prebiotic to Nourish Beneficial Gut Bacteria As a fermentable fiber, Propol® A selectively feeds healthy intestinal flora, supporting microbiome balance, immune function, and overall gut vitality.*

Why Propol® A Stands Above Ordinary Glucomannan

Shimizu Propol® A is produced using a patented multi-step purification process that removes impurities and maximizes molecular weight and viscosity—delivering up to 20 times the swelling capacity of standard konjac fibers. This results in superior stability through stomach acid and small intestine enzymes, ensuring the fiber reaches the colon intact to provide maximum satiety, metabolic, and prebiotic benefits. Backed by multiple human clinical studies, Propol® A offers clinically meaningful support for weight management, metabolic parameters, and digestive health in a clean, vegetarian capsule.*
