In addition to its role in the production of vitamin K and lactase, acidophilus is useful for treating bacterial vaginosis as well as vaginal yeast infections, explains the University of Maryland Medical Center. It may also help prevent antibiotic-induced diarrhea, treat the symptoms of irritable bowel syndrome and inflammatory bowel disease, and treat chronic constipation. Acidophilus has also been used to treat eczema, high cholesterol and pollen allergies, but there is less scientific evidence for these applications.
Lactobacillus acidophilus is available as a liquid, in capsules, in tablets and in powder form, according to Healthline. It can also be found in fermented foods, such as yogurt, kefir and pickles. Yogurt is an especially rich source of acidophilus, as the probiotic is used to culture the cream.
