How to Select an Acidophilus Supplement

Many people are turning to probiotics to help them keep their digestive tracts in healthy condition. This may mean eating yogurt that is supplemented with acidophilus, a good bacteria that is found naturally in the lower intestine. Not all yogurt contains acidophilus and many people are lactose intolerant, so a doctor may suggest that you take acidophilus supplements orally to gain the same benefits. Acidophilus can be particularly beneficial if you have been prescribed antibiotics. Because antibiotics deplete the good bacteria in your system, you may need to replenish it. If you are taking antibiotics for an infection or need acidophilus for other reasons, talk with your doctor to determine the correct dosage. The following guidelines will help you select which type of acidophilus supplement to take.

    Consider whether acidophilus yogurt or milk is right for you. If you prefer to get acidophilus from a dairy product, there are many on the market. However, a probiotic yogurt or milk may contain other strains of good bacteria in addition to acidophilus. Look at labels carefully and make sure L. acidophilus is listed.

    Choose acidophilus tablets. These come in chewable form and are good for children and adults who have difficulty swallowing pills. Tablets contain between 1 and 2 billion units of acidophilus and can be taken up to 3 times daily.

    Select capsules of acidophilus. Capsules contain between 1 and 10 billion units of acidophilus bacteria, and can be taken up to 3 times per day with a glass of water. Capsules are the most common form of acidophilus due to their ease of use.
    • Consider coated capsules in cases of stomach upset. If you have been taking antibiotics for an infection and have gastrointestinal problems such as stomach upset or diarrhea, an enteric coating on the capsules may help to ease the symptoms of stomach upset. Enteric coating allows for the pill to dissolve in the intestine rather than in the stomach, which could cause irritation.

    Take acidophilus powder. Powder is preferred by people who do not care for pills, or who choose to take acidophilus with food. Powder can be sprinkled on foods or added to milk or juice. It is recommended that you take 1/4 tsp. (1.23 ml) of acidophilus powder daily, once each morning.

    Check the labels on capsules and tablets for different strains. Like yogurt, acidophilus supplements often contain multiple strains of bacterium in addition to acidophilus. If you wish to take only acidophilus, check labels.

    Look for a guarantee on the supplement label. The product will have a guarantee if it contains at least 1 billion units of L. acidophilus. Without a guarantee, the supplement may still contain strains of good bacteria, but not necessarily acidophilus.


  • Signs of an allergy to acidophilus are swelling of the tongue, mouth or lips. Call a physician and cease taking any supplements if this occurs.
  • Consult your doctor about any medications or other supplements you take before starting an acidophilus regimen.
