What Is Acidophilus (Lactobacillus Acidophilus)?
Probiotics are defined by the National Institutes of Health Center for Complementary and Alternative Medicine (NCCAM) as "friendly" microorganisms, usually bacteria, that grow naturally in the human intestine and protect us against "bad" bacteria that can cause disease.
Lactobacillus acidophilus is sold under the brand names Acidophilus, Bacid, Flora-Q, and Novaflor.
It works by creating a hostile environment for the "bad" bacteria, and is often recommended as a supplement to antibiotics, which kill both good and bad bacteria equally, upsetting the intestinal balance.
It's believed that probiotics such as lactobacillus acidophilus help promote gastrointestinal health by restoring equilibrium.
Acidophilus Warnings
Although acidophilus has been used to treat or prevent a wide range of ailments, including yeast infections, diarrhea, irritable bowel syndrome, lactose intolerance, intestinal problems, and urinary tract infections, the Food and Drug Administration (FDA) has not approved any of these health claims.While acidophilus produces few side effects, data on safety, especially long-term safety, are limited, according to NCCAM.
Since the FDA does not regulate probiotics, concerns about quality control have been raised. Some probiotic products have been found to contain either fewer live organisms than claimed, or different bacterial strains than those listed on the label, according to NCCAM. Some have been found to be tainted with toxic chemicals or other drugs.
Before taking acidophilus, tell your doctor if you have any other medical conditions, especially a compromised immune system or allergies. If you are receiving chemotherapy or other treatment that might impair your immune system, you need to discuss taking probiotics with your doctor.
If you are sensitive to lactose, you may experience stomach pain from products that contain lactobacillus acidophilus.
Avoid lactobacillus acidophilus if you have intestinal damage or an overgrowth of bacteria in the intestine, because of the higher risk that bacteria could leave the gastrointestinal tract and potentially cause sepsis (when infection spreads throughout the body).
Lactobacillus acidophilus should not be taken by people with artificial heart valves because there's a small risk of bacterial infection.
Pregnancy and Acidophilus
If you are pregnant or thinking of becoming pregnant, or considering breastfeeding, talk to your doctor before taking acidophilus.Lactobacillus acidophilus vaginal tablets and a lactobacillus acidophilus-containing culture have been studied in pregnant women, and were found to produce no harmful side effects.

It's been suggested that giving lactobacillus acidophilus to infants less than six months old might increase their risk of developing allergies to cow's milk.
Lactobacillus acidophilus has been used to treat colic in infants, but there's insufficient evidence as to its safety.
