Not all bacteria are bad. Lactobacillus acidophilus is one beneficial bacterium that helps maintain digestive and vaginal health. It is found naturally in some probiotic yogurts, kefir, and soy products. One of the easiest ways to access this important nutrient is by taking supplements.

Lactobacillus acidophilus helps convert the sugars in milk to lactic acid. It also helps maintain a healthy balance of bacteria in the gut and vaginal tracts.

This supplement is used to treat diarrhea and promote comfortable bowel movements. Some people also use it to help with lactose intolerance and irritable bowel syndrome. Some women turn to Lactobacillus acidophilus when they have vaginal yeast infections. It has also been used to increase the absorption of calcium and other important nutrients.

Lactobacillus acidophilus is available as a capsule, tablet, liquid, or powder.

A number of bacteria live in different parts of the human body. It is important to maintain a strong colony of good bacteria in the digestive system to prevent harmful bacteria from causing health problems.
