Using to combat H Pylori instead of the horrible antibiotics that don't work, but do screw up your gut flora, therefore, messes with your entire system. Even my pharmacist warned me about how bad the antibiotics are! I made great progress with Bio-HPF, thought I had HP just about eliminated...then ran out of pills! Ordered elsewhere, with a backorder wait time of 3-4 wks! In stock and shipped quickly by this vendor.
