PGX (PolyGlycopleX) granules are an unsweetened highly viscous combination of well purified water-soluble polysaccharides derived from konjac root, sodium alginate, and xantham gum. Viscous fibres have been shown to reduce postprandial glucose concentrations and lower total and LDL-cholesterol, primarily by forming a gel matrix which slows gastric emptying.1,2Â These viscous granules also trap ingested carbohydrates and lipids inside the gel matrix, decreasing the transport as well as the uptake of glucose and cholesterol at absorptive surfaces.
