Konjac Glucomannan — Product Summary
CAS No.: 37220-17-0
Konjac Glucomannan (KGM) is a high-molecular-weight water-soluble dietary fiber extracted from Amorphophallus konjac tubers, renowned for its extraordinary ability to absorb water and swell 80–100 times its own weight, forming a highly viscous gel in the stomach. With a caloric value of only approximately 0.1–0.3 kcal/g, KGM is among the lowest-calorie functional fibers available.
This extreme swelling capacity physically fills the gastric cavity, triggering mechanoreceptor-mediated satiety signals and delaying gastric emptying for 2–4 hours — enabling sustained caloric deficit without hunger, a critical advantage for fat loss and body recomposition.
KGM's viscous gel also slows carbohydrate and lipid absorption, improving insulin sensitivity and lowering serum cholesterol. As a prebiotic, it ferments in the colon to produce short-chain fatty acids that strengthen gut barrier function and reduce exercise-induced inflammation.
Unlike maltodextrins or other caloric fillers, KGM provides maximum volumetric satiety with near-zero calories, making it a cornerstone ingredient in meal replacements, slimming powders, konjac-based "zero-calorie" foods, and clean-label weight management formulations for fitness-focused consumers.

Uses:
Polydextrose — Bulking Dietary Fiber for Sports Nutrition & Body Shaping
CAS No.: 68424-04-4
Polydextrose is a synthetic water-soluble dietary fiber synthesized via vacuum polymerization of glucose and sorbitol, with an average degree of polymerization of 20 and a low molecular weight (average ~3200 Da). As a functional bulking fiber, it delivers only ~1 kcal/g — approximately 1/4 the caloric density of conventional digestible carbohydrates — with a neutral taste, low viscosity, and excellent gastrointestinal tolerability (no gas or bloating even at higher intakes). It also functions as a prebiotic, selectively stimulating the growth of beneficial gut bacteria such as Bifidobacterium and Lactobacillus in the colon, where it is partially fermented to produce short-chain fatty acids (SCFAs).
Functional Benefits in Sports Nutrition & Body Shaping
Enhanced Satiety & Caloric Control: Polydextrose absorbs water and expands in the stomach to delay gastric emptying, prolonging the sensation of fullness and reducing overall energy intake. Its ultra-low caloric density allows formulators to create low-calorie meal replacements, protein bars, and weight-management shakes without sacrificing texture or mouthfeel — a critical advantage for athletes and fitness enthusiasts in caloric deficit phases aimed at fat loss or body recomposition.
Improved Insulin Sensitivity & Glucose Stability: Unlike rapidly digested sugars, polydextrose does not trigger sharp postprandial blood glucose or insulin spikes. Regular consumption has been shown to slow glucose absorption, improve insulin sensitivity, and reduce visceral fat accumulation — supporting metabolic flexibility and lean muscle preservation during both cutting and bulking phases.
Lipid Metabolism Regulation: Polydextrose forms a thin film in the small intestine that partially encapsulates dietary fat, limiting its absorption, while also binding bile acids to promote their excretion, thereby lowering serum total cholesterol and triglyceride levels. These effects contribute to improved body composition by reducing adipose tissue storage.
Gut Health & Recovery Support: As a prebiotic fiber, polydextrose fermentation in the colon produces SCFAs (particularly butyrate) that strengthen the intestinal barrier, reduce exercise-induced gut permeability and systemic inflammation, and enhance mineral absorption (calcium, magnesium) — all of which support bone health, muscle recovery, and immune function for active individuals.
Differentiation from Conventional Carbohydrates
Unlike rapidly digested maltodextrins or glucose that are hydrolyzed into simple sugars and cause sharp blood sugar fluctuations, polydextrose resists upper GI digestion entirely and functions primarily as a bulking prebiotic fiber rather than a caloric energy source. This unique profile makes it a preferred ingredient for:
Low-calorie, high-fiber meal replacement shakes
Reduced-sugar protein bars and snacks
Clean-label sports nutrition beverages
Weight management and body shaping formulations
Polydextrose has become a go-to functional fiber for fitness-oriented consumers seeking to manage carbohydrate intake while supporting gut health, metabolic stability, and long-term lean body composition goals.
