The Impact of Probiotic Supplementation on General Well Being

April 16, 2025 updated by: Cwm Taf University Health Board (NHS)
The health and wellbeing of any workforce is a core priority and taking steps to ensure the wellbeing of employees is an important part of everyday working life. Winter is a time of particular challenge and is linked to increased absenteeism. There is a growing awareness that probiotics (similar to the bacteria found in yogurts) can play a role in boosting general wellbeing. Probiotics are known as 'good' or 'friendly' bacteria and are living organisms that are found naturally in yogurt and fermented foods. They can be capsules, tablets or powders in sachets that are taken daily to help to keep the gut in peak condition. Everyone has trillions of bacteria in their guts living together happily and they are needed to boost our wellbeing but the stresses and strains of everyday life can often disturb their balance, probiotics can help to restore the balance. Over the winter of 2022, a small exploratory study with employees based in South Wales who were offered the opportunity to 'try out' a probiotic manufactured by Cultech Limited (a company based in Port Talbot specialising in the production of nutritional supplements). The results were very promising with significant improvements in wellbeing and reduced absenteeism among those who opted to take the product. This project is designed as a follow-up on last year's exploratory study to further assess effectiveness of the same probiotic nutritional supplement over the winter
