Several strains of bacteria live in the colon. Good ones and bad ones. Vivinal GOS is food for the good bacteria. The good bacteria grow faster and therefore the bad bacteria in your colon decrease. This provides a number of health benefits such as, relief of constipation, support of natural defences, growth of bifidobacteria and improved mineral absorption.
Vivinal GOS is an ingredient rich in galacto-oligosaccarides. It is derived from lactose (milk sugar). Lactose is a disacaccharide and consists of mono sugars, galactose and glucose. (Figure 1)

Figure 1: Composition lactose
During an enzymatic process, lactose is first cut in glucose and galactose. After cutting, the enzyme builds sugar strings of different lengths from galactose with one glucose unit. (Figure 2)
