Food Additive Galacto-oligosaccharide GOS Galactooligosaccharide 

What's Galacto-oligosaccharide?
GOS is galacto-oligosaccharides with great similarities to the composition of human milk, and is
highly promoted for use in the infant formula and healthfoods because of its combination of benefits and safety.
GOS is composed of galactose molecules with one glucose on the end, altogether containing 3-8 simple
sugars. GOS cannot be digested in the human small intestine, so it travels unchanged into the large
intestine, where beneficial colonic bacteria break them down into gases and short-chain fatty acids
(SCFAs), which can be absorbed and used by the body.
