Probiotics are ‘friendly’ live bacteria that are often added to yoghurts or taken as food supplements.
Evidence suggests that taking a probiotic supplement can help to prevent diarrhoea whilst taking antibiotics, and can help to ease some of the symptoms of irritable bowel syndrome (IBS).
The best way to find out if probiotics work for you is by giving them a go, as some of them will work differently for different people.
