Lactobacillus acidophilus belongs to a group of bacteria that normally live in the human small intestine and vagina. L. acidophilus is one of the most commonly used probiotics, or "good germs." These are microorganisms that help to maintain a healthy intestinal tract and aid digestion. Common food sources of L. acidophilus include yogurt and fermented soy products, such as miso and tempeh.
Multiple human trials report benefits of L. acidophilus for bacterial vaginosis, a common infection of the vagina. L . acidophilus has long been used as a therapeutic agent for gastrointestinal disorders. However, this and other medicinal uses of L. acidophilus are not supported by strong clinical evidence.
