One of the most studied probiotics in the world

BioGaia’s probiotic products with Lactibacillus reuteri are among the most scientifically well-documented probiotics in the world with regard to both efficacy and safety. To date the efficacy and safety of BioGaia’s different strains of L. reuteri have been documented in 203 clinical studies in 17,200 people of all ages.

Lactobacillus reuteri has shown result in 105 clinical studies in children, from newborns up to 18 years old, and 98 studies in adults. Probiotic strains that have been used in clinical trials are BioGaia Protectis (DSM 17938), BioGaia Gastrus (ATCC PTA 6475) and BioGaia Prodentis (ATCC PTA 52899. Results have been published in 180 papers in scientific journals (February 2019).

The results indicate that L. reuteri Protectis may help in functional gastrointestinal disorders such as colic, regurgitation, constipation and functional abdominal pain. Different L. reuteri strains have also been used in clinical trials for indications like acute gastroenteritis and antibiotic associated side-effects. Oral health and infection protection are other areas where L. reuteri strains have been shown beneficial.
