Summary

What are probiotics? Probiotics are viable (living or hibernating) bacteria and/or yeasts that confer a health benefit. Probiotics are sold as cultured foods and beverages, such as yogurts and kefirs, as well as in capsules, tablets, and powders.

What are the health benefits of probiotics? Certain probiotic strains may be helpful for constipation, bloating, diarrhea and irritable bowel syndrome, while others may be helpful for throat and respiratory infections, and other uses.

What are the best probiotic supplements? We suggest that you check our Results table to find identify products "Approved" for quality in our testing. Then consider the following:

  • Choose a product that contains the type(s) and amounts of probiotic organism(s) shown to work for your condition. See the "What They Do" section and then check the Results table for products that contain that/those organism(s).
  • See our Top Picks for some of the most common uses of probiotics.
  • Be aware that there can be huge variation in the number of viable cells (CFUs) from product to product. Among products tested, this ranged from just 100 million to hundreds of billion! Typically, an adult probiotic should provide at least 1 billion cells daily — although, as discussed in the "What They Do" section, some probiotics have been shown to work at a lower dose.

Caution: If you have a milk allergy, be aware that trace amounts of milk proteins may occur in some probiotics (see Concerns and Cautions).

Update

UPDATE (4/23/20):
CL was contacted this month by the company that makes one of the probiotics that was Not Approved in this Review due to two independent laboratories finding it to be contaminated. The company disputed CL's results, and we've offered the company an opportunity to retest the product at a third-party laboratory of mutual acceptance.
You must be a member to get the full test results along with ConsumerLab.com recommendations and quality ratings. You will get results for 38 probiotic supplements, including three products for pets. Twenty-three products were selected by ConsumerLab.com and 15 others are included for having passed testing in its voluntary Quality Certification Program.
