Acidophilus probiotic complex is a supplement containing the bacteria lactobacillus acidophilus, which treats diarrhea, improves digestion and skin disorders. The bacteria normally lives in the digestive, urinary and genital tracts, according to WebMD.
Lactobacillus acidophilus can be used to treat some digestion issues, such as irritable bowel syndrome and colic, and some skin disorders, such as fever blisters, canker sores and eczema. Women also can use this medication to treat yeast infections and urinary tract infections, according to MedlinePlus.
However, MedlinePlus warns that some acidophilus products contain different strains of lactobacillus that are not lactobacillus acidophilus or may be contaminated.
