Summary: What You Need to Know About Probiotics
There is such a variety of probiotic products available for purchase that choosing one can be difficult. On top of that, our tests showed that some products are lacking in quality and were "Not Approved". To help, we suggest that you first 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).
    • COVID-19 UPDATE: Probiotics have been promoted on some websites to help prevent or treat COVID-19, the infection caused by the SARS-CoV-2 virus. There is no direct evidence of such a benefit. There is preliminary evidence that certain probiotic strains have anti-viral effects (based on studies with other viruses) and some physicians in China have reported imbalances in intestinal bacteria in patients with COVID-19. See the COVID-19 section for details.
  • 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.
  • Cautions If you have a milk allergy, be aware that trace amounts of milk proteins may occur in some probiotics (see Concerns and Cautions).
You must be a member to get the full test results along with ConsumerLab.com recommendations and quality ratings. You will get results for 36 probiotic supplements, including three products for pets. Twenty-three products were selected by ConsumerLab.com and 13 others are included for having passed testing in its voluntary Quality Certification Program.

    • Which probiotic supplements and drinks failed our tests and which ones passed
    • CL's Top Picks among probiotic supplements by category, including probiotic supplements for immune system health, diarrhea, constipation, irritable bowel syndrome (IBS), women's health and for pets
    • Which probiotic bacteria or yeasts have been shown effective for treating or preventing specific conditions, and at what dose. These microorganisms include Lactobacillus acidophilus, Lactobacillus GG, Bifidobacterium infantis, Saccharomyces boulardii, and many others
    • Price comparisons of probiotics supplements and drinks
    • Ingredient comparisons and what to look out for on probiotic labels
    • What prebiotics (often included in probiotics) can and cannot do, and how to get them from supplements and foods
    • Tips on how to use probiotics — and store them to last longer  
    • Concerns, cautions, and potential side effects of probiotics and probiotic-containing drinks -- including concerns for people with milk allergies

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.
