PolyGlycopleX is a blend of natural, non-starch soluble fibers that act synergistically to develop a higher level of viscosity than other dietary viscous fibers known. This blend forms a unique gel that moves slowly through the gastrointestinal tract
Synergistic Viscosity!
All kidding aside, there are cheaper sources of fiber, like metamucil or other supplements. Or, you know, food.
