About





            

                
Lactobacillus gasseri is a probiotic species that naturally inhabits the human stomach and intestinal tract. Research suggests the LG21 strain may help support healthy pepsinogen production and gastric function, and has been studied for its potential to suppress H. pylori colonization. It may also help modulate gastric acid secretion, supporting overall upper GI comfort.

            

        

        

        
        
        

            

  
How It Works





            

                
Increases pepsinogen production accelerating protein digestion; suppresses H. pylori colonization through competitive exclusion and lactic acid production; modulates gastric acid secretion via interaction with parietal cell signaling; promotes healthy gastric mucosal environment.
