Probiotic goods a 'waste of money' for healthy adults, research suggests

University of Copenhagen study finds no evidence that so-called friendly bacteria change the composition of faecal bacteria

Fans of probiotic drinks and foods may be wasting their money, according to a review of current research into the supplements that suggests they may be of no benefit to healthy adults.

A Danish team looked at the results of seven trials of the products - often sold as milk-based drinks, biscuits, sachets, or capsules - and found no evidence they changed the composition of faecal bacteria in healthy adults.
