Make sure the probiotic supplement you take passed our tests!
Isn't your health worth it?
Which are the best probiotic supplements and bottled kefirs (cultured milk with probiotics)? This report will help you find out.

If you are taking a probiotic to help with a specific condition, it is important that you first select a probiotic that provides the specific bacteria or yeast shown to help with your condition, such as irritable bowel syndrome (IBS), abdominal pain, infections, diarrhea, cold and flu, and even high cholesterol, anxiety, and weight control. The clinical evidence is provided in this report.

What's more, you need to know proper dosage. The amount of cells provided by probiotic products in this review alone ranged by more than 900,000%, from just a few million per daily serving, to as much as 900 billion!

You also need to know if the product contains its listed amount of viable (living) probiotic organisms. Our tests found some which did not -- containing less than half of what was listed on their labels. If you own a pet, be aware that one of the three products we tested for dogs and cats had a relatively tiny number of organisms and would seem unlikely to be effective.

Fortunately, we also found many probiotics with the number of organisms they claimed -- typically billions. In addition, we checked to make sure these products were not contaminated with other organisms, such as molds and certain disease-causing bacteria.

Probiotics tend to be expensive, so we show which offer good value

Among kefirs, we found enormous differences in the amounts of live cells by brand. Kefirs are touted as more digestible than milk for people with lactose-intolerance, so we also analyzed their lactose content, and were shocked by our findings — refuting a claim on one the products!

If you are trying to find the best probiotic for your needs, read this report about probiotic supplements for adults and children, and even for dogs and cats. You'll get test results for 43 probiotic products -- 21 selected by for review and 22 others that passed voluntary quality certification testing, as well as information about two supplements similar to one that passed testing. You'll also find out what's in 3 popular kefir products. You'll  
    • Which probiotics supplements and kefirs passed or failed our tests and how many viable cells they contained
    • 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 and kefirs
    • Ingredient comparisons and what to look out for on probiotic labels
    • Tips on how to use probiotics — and store them to last longer 
    • Concerns, cautions, and potential side effects of probiotics -- including concerns for people with milk allergies
