Naturally occurring in the digestive tract and vagina.
L. acidophilus is a type of healthy bacteria that inhabits the intestines and vagina and protects against some unhealthy organisms. L. acidophilus breaks nutrients down and produces lactic acid, hydrogen peroxide, and other byproducts that make the environment hostile for undesired organisms. L. acidophilus also outcompetes possibly harmful bacteria in the digestive tract. During digestion, L. acidophilus also assists in the production of niacin, folic acid, and pyridoxine.
Some research has indicated that L. acidophilus may improvee gastrointestinal function, boost immune system, and decrease the frequency of vaginal yeast infections
