Pilot study suggests synbiotic has "profound effects" on emotional health

In this study, fourteen charity workers completed a Wellbeing Process Questionnaire before and after a six-week intervention involving the consumption of a kefir and prebiotic mixture (170ml Chuckling Goat kefir, 10g prebiotic powder and a banana).

Conducted by Dr Miguel Toribio-Mateas, Clinical Neuroscientist and Honorary Research Fellow at Cardiff University, and Professor Andrew Smith, Director of the Centre for Occupational and Health Psychology at the Cardiff University’s School of Psychology, the results suggest that several aspects of wellbeing significantly improved after intervention. 

Dr Mateas asserts: “The outcomes of the study were both striking and enlightening. Participants reported a noticeable decrease in daytime sleepiness and an increased sense of immersion and engagement in their work. More importantly, they experienced an uplift in their overall life satisfaction and a heightened sense of flourishing.

“These findings are remarkable because they are not just abstract concepts. They’re real, tangible experiences that significantly impact our daily lives and our ability to function at our best. Life satisfaction, a measure of how content people are with their lives, and thriving, a reflection of personal growth and the ability to overcome challenges, are essential indicators of mental health and wellbeing.

“On that basis, the study suggests that synbiotics may play a role in enhancing these aspects, indicating a connection between gut health and mental wellbeing in the workplace.”
