Probiotics.org does not have commercial ties with any probiotic brands, so we can be 100% objective in how we rate our probiotics. We rate the probiotic based on its ingredients, strains, probiotic strength & company ethics and reputation.
We tend to focus on reviewing the most widely available probiotics so we can help educate as people as possible.
You should also check out our Personalized Probiotic Finder. It recommends the top 3 probiotics for your symptoms, age & sex based on 153 probiotic research studies and 653 supplements.
