When it comes to choosing effective probiotics, Clinically Documented Strains Matter.™ Since the beginning, our founding mission at Jarrow Formulas® has been to innovate and create products that put science first, with a focus on clinically validated probiotic strains.

Researchers conduct years of studies on strains before one is identified and selected as a “probiotic.” There are many commercially available strains within any given probiotic species. For example, bacteria that have been identified as beneficial within the Lactobacillus rhamnosus species can have assigned ID designations such as R0011, R0052, LBV96, or GR-1® following the genus (Lactobacillus) and species (rhamnosus) names. The strain ID is confirmation that the specific Lactobacillus rhamnosus strain present in that product has been documented specifically for health benefits.*

Jarrow Formulas takes great pride in using high-quality and scientifically studied probiotic strains that have been developed alongside partners like Lallemand-Institut Rosell, Chr. Hansen, and Morinaga Dairy. That’s why Jarrow Formulas probiotics contain high-quality, clinically documented strains that have been developed through years of research and innovation for effectiveness. Our probiotic products clearly list strain identifications in the supplement facts panel of every formulation for full transparency to ensure consumers that the company’s probiotics have been validated by science.

A focus on science-based products that consumers trust has helped make Jarrow Formulas the #1 probiotic brand for customer satisfaction according to ConsumerLab.com’s Survey of Supplement Users for 2021.† As an innovator of consumer probiotics, Jarrow Formulas has long advocated the scientific wisdom of formulating multi-strain probiotics which utilize specially selected bacteria strains that best support targeted health benefits such as intestinal and immune health.*

Choose science. Choose Jarrow Formulas® Probiotics.
