Supplement
Probiotics for women
Probiotics as a category carry no authorised EFSA health claim in the UK, so a product cannot legally state it supports gut health, digestion or immunity generally. The one narrow, authorised exception is that live yoghurt or fermented milk cultures improve lactose digestion in people who have difficulty digesting lactose. Individual strains have been researched for specific uses, but no general claim has cleared the regulatory bar. Check the CFU count and named strain on the label, not just the word probiotic, and speak to your GP or pharmacist before starting one for a specific condition.
What it does
Here we have to be straight with you, because probiotics are not like a nutrient such as calcium or vitamin D. Checked against the GB nutrition and health claims register:
- In short, probiotics as a category carry no authorised EFSA health claim, so a product cannot legally state it supports gut health, immunity or digestion in the UK.
We explain it so you can recognise marketing that runs ahead of what is authorised, not to say the underlying research on specific strains doesn't exist.
Who it is for
People take probiotics for many different reasons, from general wellbeing to a specific digestive symptom to alongside a course of antibiotics. Because the right strain and evidence base differs by reason, a probiotic chosen off a general "gut health" marketing claim is not the same decision as one chosen with a GP or pharmacist for a specific issue.
What to look for when buying
- Be cautious of marketing that promises gut health, bloating or immunity benefits; those promises go beyond what the rules allow.
- Check the CFU (colony-forming units) count and the named strain on the label; "probiotic" alone tells you very little, since different strains have been studied for different things.
- Refrigeration and expiry matter for live-culture products; a product stored or shipped incorrectly may not deliver the CFU count printed on the label.
- If you are taking probiotics alongside antibiotics or for a specific digestive condition, speak to your GP or pharmacist, since the right strain and timing depend on the reason you are taking it.

Frequently asked questions
Are probiotics EFSA-approved?
No, not as a category: none of the general claims submitted for probiotics has been authorised, as What it does, above, explains. The one narrow exception is that live yoghurt cultures improve lactose digestion in people who have difficulty digesting lactose.
If there is no authorised claim, does that mean probiotics do not work?
No: it means the evidence submitted so far has not met the regulatory bar for a general "probiotics support gut health" claim, not that no strain has ever shown an effect in a study. Treat specific strain research and general marketing claims as different things.
What does CFU mean and does a higher number mean better?
CFU stands for colony-forming units, a measure of how many live organisms a dose contains at the time of testing. A higher CFU count is not automatically better; the strain, whether it survives stomach acid, and storage conditions all matter as much as the raw number.
Can I take probiotics with antibiotics?
Many people do, but timing and strain choice matter, and the reason you are taking a probiotic (general use versus a specific digestive issue) changes the advice. Speak to your GP or pharmacist rather than guessing.
