Explanation of criteria

  1. Transparent Formula: The supplement’s ingredients and their amounts are openly labeled, not hidden behind proprietary blends. This transparency is essential for us to verify that it meets the studied dose requirements.
  2. Studied Dose: For BGN4 x AD011 x AD031 x IBS041 in IBS populations, the effective dose is 40 billion CFUs per day. Any product that delivers this specific dose in one or more servings meets this criterion.
  3. IBS RCT Probiotics Only: The product contains only probiotic strains that have been studied in IBS populations through randomized, placebo-controlled clinical trials. No other active ingredients are included, as unstudied additives may alter efficacy.
  4. Third-Party Tested CFUs: The manufacturer has submitted the product for third-party testing to verify both the CFU count (amount of probiotics in finished product) and has published the results on their website.
  5. Availability: Indicates where the product can be purchased. Please note that consumers worldwide can often access USA and UK products using a forwarding service.
