Probiotics
Probiotics are live bacteria and yeasts sold as supplements, yoghurts and drinks.
Short answer Probiotics are live bacteria and yeasts sold as supplements, yoghurts and drinks. There is some evidence they help in a few specific situations, such as diarrhoea linked to antibiotics, but no probiotic has an authorised general health claim in Great Britain.
Where the evidence is best
Reducing the chance of diarrhoea when taking antibiotics, and easing some symptoms of irritable bowel syndrome in some people. Effects depend on the strain, and one product's results do not transfer to another.
Why packs say so little
Because 'supports gut health' and 'boosts immunity' are health claims, and none has been authorised for probiotics. A careful brand names its strains and the number of live bacteria at the end of shelf life.
How to choose
| Check | Why |
|---|---|
| Named strains | Evidence is strain-specific |
| Count guaranteed to end of shelf life | Bacteria die off in storage |
| Storage instructions | Some need a fridge |
| A four-week trial | If nothing changes, stop |
Who should be careful
People with a weakened immune system or who are seriously ill should ask a doctor first.
