What did the science find?

A new clinical study by the Department of Psychosomatic Medicine and Psychotherapy at the University Hospital of Tübingen has confirmed that the bacterial culture 1714® (1714-Serenitas®can both improve stress processing and make it easier for healthy people to deal with stress.

This clinical trial showed for the first time that the 1714® culture enables better stress management by changing brain processing in response to stress.



How was the clinical study conducted?

For the study, 40 healthy people took either 1714® or a placebo daily for four weeks. They were exposed to a social stressor before and after the four-weeks and their brain activity was measured.

The clinical trial showed clearly that the 1714® strain produces changes in the brain that are linked with stress regulation, indicating improved coping with stressful situations.

The trial also showed that 1714® can produce changes in the brain regions associated with stress management, stimulating the coping centres in the brain.
