What is EvidenceBiotics?

Your microbiota is a vast, interconnected ecosystem of trillions of microorganisms. Among them are helpful bacteria – the Invisible heroes working quietly in the background throughout your body, including on your skin, in your mouth, throat, and gut.

Everyday life constantly influences these microbial communities. New foods, new environments, travel, stress, or aging can all disrupt your family's routine. When your routine is disrupted, science helps you make informed choices.

That is where BioGaia comes in. BioGaia EvidenceBiotics™ are selected probiotic bacterial strains backed by rigorous clinical research.
