About





            

                
Galactooligosaccharides (GOS) are prebiotics synthesized from lactose that selectively promote the growth of beneficial Bifidobacterium species. Research suggests GOS may help reduce IBS symptoms including pain, bloating, and flatulence in a dose-dependent manner. Interestingly, studies indicate that a moderate dose (3.5 g/day) may be more effective than higher doses, which can cause excess fermentation.

            

        

        

        
        
        

            

  
How It Works





            

                
Synthesized from lactose, resistant to human digestive enzymes; selectively promotes Bifidobacterium growth; reduces pathogenic Clostridium colonization via competitive exclusion; lowers stool pH through SCFA production; enhances calcium absorption.
