Is acidophilus milk good for digestion?

Quick answer

There is no official proof that acidophilus milk improves digestion. It still contains lactose, so it is not a fix for lactose intolerance. NIH says probiotics have a long history of apparently safe use, mainly in healthy people, and should not delay seeing a provider about a health problem.

Is acidophilus milk good for digestion?

Possibly for some people, but it is not proven. Acidophilus milk is cow’s milk containing Lactobacillus acidophilus. The NIH probiotics page says probiotics have a long history of apparently safe use, mainly in healthy people, and it does not name acidophilus milk as a treatment.

Will it help with lactose intolerance?

Do not count on it. It contains lactose unless the label says lactose-free. If dairy causes symptoms, try a small amount first or choose a labeled lactose-free product.

Could it cause gas or bloating?

Any new food can upset a stomach. If symptoms continue, stop and talk to a doctor.

Who should avoid it or ask first?

  • People with serious illness or weakened immune systems.
  • Premature infants, where the NIH quotes an FDA warning about severe infections with probiotics.
  • Anyone allergic to milk.

When to see a doctor

Ongoing diarrhea, blood in stool, weight loss, severe pain or fever need medical advice. NIH says probiotics should not be used to delay seeing a provider.

How to try it

  1. Choose a product from the refrigerated aisle and check the date.
  2. Start with a small glass and see how you feel.
  3. Check the date and keep it cold.

Other options

Plain yogurt and kefir are also cultured dairy products and are different foods. This is general information, not medical advice.

What does the label tell you?

Check whether the product says acidophilus, is flavored or sweetened, and whether it is labeled lactose-free. Keep it refrigerated and use it by the date on the pack.
