Offers several health benefits

Polylactose, a novel dietary fiber, shows great promise as a prebiotic additive to human food products or supplement. Created by polymerizing lactose (a component of dairy whey), polylactose is highly fermentable, and had a profoundly positive effect on the colonic microflora. Preclinical studies showed significantly reduced body fat, lowered plasma leptin concentrations, improved blood glucose control and reduced fatty liver at a dietary concentration where other prebiotics were ineffective.

Easily incorporated into foods

Current prebiotic ingredients, fructans (fructo-oligosaccharide and inulins) and galacto-oligosaccharide, offer health benefits such as weight reduction and glycemic control. Most prebiotics, however, cannot reduce excess body fat or fatty liver or improve blood glucose control. While viscous dietary fibers (i.e., guar gum and hydroxypropyl methylcellulose) may offer these benefits, their slimy/gummy texture is unpleasant to most consumers. Polylactose powder, on the other hand, should be very easy to incorporate into foods and can be manufactured at a reasonable cost. It may also impart several of the health benefits (e.g., reduced body fat, reduced fatty liver and improved blood glucose control) current prebiotics lack.
