Microorganisms must meet stringent criteria to be used as probiotics, including being non-pathogenic, non-toxic, and able to survive stomach acid and pancreatic secretions. Probiotics confer health benefits such as enhancing the immune system, producing vitamins, preventing GI infections, and aiding in lactose digestion, potentially treating conditions like IBS and eczema.
