Galacto-Oligosaccharide 27% Powder

Galacto-oligosaccharides are made up of plant sugars linked in chains. They are found naturally in dairy products, beans, and certain root vegetables. People use galacto-oligosaccharides as prebiotics. Prebiotics act as food for "good" bacteria in the intestine. Don't confuse prebiotics with probiotics such as lactobacillus, bifidobacteria, and saccharomyces, which are live organisms that are good for health.

In foods, galacto-oligosaccharides are used as a sweetener.
