ConsumerLab Tests Reveal Best Probiotic Supplements and Those With Quality Issues
White Plains, New York, April 14, 2020 — Probiotic supplements may be helpful for conditions including antibiotic-associated diarrhea, irritable bowel syndrome, and respiratory infections. Due to their potential immune and antiviral effects, probiotics have also been promoted to help prevent COVID-19, although there is no direct evidence to support this use.

ConsumerLab recently evaluated popular probiotic supplements sold in the U.S. and Canada, purchasing and testing capsules, powders, liquids and gummies. Most of the products were found to contain their claimed amounts of viable organisms. However, one supplement was found to be contaminated with Pseudomonas aeruginosa, a microbial contaminant which is of particular concern to immunocompromised individuals and infants. The enteric coating of another product was shown not to work properly, and a third product contained far fewer viable organisms than claimed. Amounts of viable cells in products ranged from less than 500 million to 225 billion per serving, but most contained between 1 and 50 billion. The cost to get one billion cells from products ranged from 1 cent to over $4.

Among the products that were Approved, ConsumerLab selected its Top Picks for probiotic supplements for uses relating to diarrhea due to antibiotics or travel, constipation, colic in infants, irritable bowel syndrome, flatulence, colds and respiratory infections, and vaginal infections.

The results are available online in ConsumerLab's new Probiotic Supplements Review, which includes test results and comparisons for 35 products. The following 23 products were selected for testing by ConsumerLab: Align Probiotic, Bayer Phillips' Colon Health Daily Probiotic, Culturelle Probiotics Digestive Health, Dr. Mercola Complete Probiotics, Florastor, Gerber Soothe Probiotic Colic Drops, GoodBelly Probiotics Infused - Watermelon Lime, Hyperbiotics Pro-Women, Jamieson Probiotic 5 Billion, Klaire Labs Pro-Biotic Complex, Mary Ruth's Liquid Probiotic - Unflavored, New Rhythm Probiotics 50 Billion CFU, PB8 Probiotic, ProBiora Plus - Mint, RepHresh Pro-B, Rx Vitamins for Pets RxBiotic, Schiff Digestive Advantage, Smarty Pants Kids Probiotic Complete - Grape, Trunature Advanced Digestive Probiotic, Up4 Probiotic Kids Cubes - Soft + Yummy Melts, VetriScience Vetri Mega Probiotic, Visbiome High Potency Probiotic, and Zesty Paws Probiotic Bites - Pumpkin Flavor - Dogs.
