Billions of microorganisms live on your skin, in your gastrointestinal system and in other parts of the body. One common species of bacteria found in the intestines is Lactobacillus acidophilus. L. acidophilus is considered beneficial because it reduces the population of harmful, infection-causing organisms. Before taking L. acidophilus supplements to prevent disease or improve your health, discuss your plans with a physician to ensure they are safe for you.
Features
The intestines and vagina naturally contain colonies of L. acidophilus bacteria. When the intestinal bacteria come into contact with food, they release hydrogen peroxide and lactic acid, which are toxic substances. Because these toxins kill harmful bacteria that cause disease, L. acidophilus are considered helpful bacteria that improve your health. L. acidophilus supplements are commonly used to repopulate the small intestine with beneficial bacteria after taking antibiotic medications.
Dosage
Although L. acidophilus is generally safe to use, you must carefully consider the dose you take. The University of Maryland Medical Center recommends that children take one-fourth of a capsule of L. acidophilus orally at least two hours after taking antibiotics. Adults should take 1 billion to 2 billion colony-forming units of L. acidophilus to treat diarrhea or vaginal infections. To improve general intestinal health, take 1 billion to 15 billion colony-forming units of L. acidophilus per day.
Preparations
L. acidophilus supplements may come in liquid, tablet or capsule form. The U.S. Food and Drug Administration doesn't regulate the safety and effectiveness of dietary supplements such as L. acidophilus. Look for L. acidophilus supplements that come from a reputable source to avoid potential problems. Another source of L. acidophilus is yogurt that contains live, active cultures of the bacteria. Eating 8 oz. of this yogurt per day provides your body with L. acidophilus.
Safety and Side Effects
Some people experience gas or abdominal discomfort after taking L. acidophilus supplements. More serious side effects can also occur, including diarrhea, vomiting, allergic reaction and infection. People with compromised immune systems or artificial heart valves should consult a doctor before taking L. acidophilus to prevent a dangerous bacterial infection.
