Acidophilus, also known as Lactobacillus acidophilus, is a probiotic commonly found in yogurt and fermented soy products. Acidophilus is a healthy bacterium that helps to promote digestion and protect you from harmful bacteria and from fungi such as those that cause yeast infections. Because acidophilus bacteria are often present in the human body, side effects from acidophilus supplements are rare and usually mild. Consult your physician before taking any supplements.

Safety

The National Institutes of Health's MedlinePlus website lists acidophilus as “likely safe” for most people, including babies and children. For women who are pregnant or breastfeeding, MedlinePlus states, using acidophilus supplements is "possibly safe." Lactobacillus GG has been safely studied in pregnant and breastfeeding women, but other types have not been studied. People with weakened immune systems and short bowel syndrome should be careful when taking acidophilus supplements.

Intestinal Gas, Bloating

The only side effects of acidophilus supplements, according to MedlinePlus, are intestinal gas and bloating. Intestinal gas is part of the normal digestive process and is often expelled through belching or through flatulence. Occasionally, acidophilus and other probiotics can create more intestinal gas for the first few days of use. However, acidophilus may also help to reduce bloating and other intestinal discomforts, according to an article published in the "Journal of Clinical Gastroenterology" in July 2004.

Possible Interactions

Acidophilus can potentially interact with a few medications. Antibiotics are designed to reduce bacteria in the body. Taking acidophilus along with antibiotics can reduce the effectiveness of the probiotics. If you are taking medications that suppress the immune system, such as azathioprine, basiliximab or prednisone, taking acidophilus may increase your chances of getting sick. The immune system controls the amount of yeast and bacteria in your body to prevent infections. No interactions with food or herbal supplements have been noted.

Considerations

People with lactose intolerance may develop abdominal discomfort, according to MayoClinic.com, because of a small amount of lactose contained in acidophilus. People with an artificial heart valve should not take acidophilus because there is an increased risk of an infection. The dosage of acidophilus varies depending on what you are treating. According to MedlinePlus, typical doses range from 1 to 10 billion living organisms. The dose is usually divided and taken three to four times throughout the day.
