In addition, the probiotic strain has been shown to support digestive health.


Isolated from human breast milk

The BNR17strain, a strain isolated from human breast milk, was scientifically selected from 319 strains for its role in weight support and gastrointestinal wellness. Chr. Hansen licensed the strain in 2018 based on its scientific documentation and future potential.


According to studies, Lactobacillus gasseri, BNR17 may:

  • Contribute to maintenance of a healthy weight and a healthy body mass index1

In one study, the participants taking the BNR17 strain saw a significant waist circumference decrease. The mean loss in waist circumference was five centimeters over a 12-week consumption period. The placebo group did not change significantly.1
