About





            

                
Lactobacillus acidophilus is one of the most widely recognized probiotic species, found naturally in the human gastrointestinal tract and fermented foods. It supports digestive health by producing lactic acid that lowers intestinal pH, which may help inhibit pathogen adhesion and support mucosal barrier integrity through enhanced mucin production. Research suggests it may be particularly supportive for lactose digestion and overall bowel regularity.

            

        

        

        
        
        

            

  
How It Works





            

                
Produces lactic acid lowering intestinal pH to inhibit pathogen growth; inhibits pathogen adhesion to intestinal epithelium via competitive exclusion; enhances mucosal barrier integrity through mucin production stimulation; produces bacteriocins (acidocin, lactacin) with antimicrobial activity.
