About





            

                
Resistant starch is a type of starch that escapes digestion in the small intestine and is fermented by colonic bacteria, making it the most potent natural butyrate producer among prebiotics. Research suggests it may help increase fecal butyrate concentration by 30-40%, supporting colonic cell health and gut barrier function. It feeds key butyrate-producing species including Ruminococcus bromii and Eubacterium rectale.

            

        

        

        
        
        

            

  
How It Works





            

                
Escapes small intestine digestion reaching the colon intact; fermented primarily to butyrate (highest butyrate-producing prebiotic) by Ruminococcus bromii and Eubacterium rectale; increases fecal butyrate concentration by 30-40%; supports colonocyte energy metabolism and tight junction integrity.
