Commenting on this new study, Professor Enck said:

‘As researchers in the placebo effect, we have been sceptical about many of the claims made about bacterial cultures and the gut-brain axis. We have significant experience in the placebo effect and so our team designed a comprehensive study to assess this strain.
We think the results are novel and innovative and provide a scientific basis to assess the true impact of specific bacterial strains on the brain.’
