What is in gut health?

Gut health products divide into a few types. Probiotics supply live bacteria. Prebiotics supply the fibres those bacteria feed on, such as inulin and resistant starch. Digestive enzymes help break down specific components, lactase for lactose being the clearest example. Then there are soothing ingredients such as glutamine, slippery elm and peppermint oil.

The most important thing to understand about probiotics is that effects are strain specific. Lactobacillus rhamnosus GG and Saccharomyces boulardii have been studied for particular uses, and results from one strain do not transfer to another simply because both are probiotics. A product listing only genus and species, without the strain, is giving you less information than it appears to.

How it is usually used

Probiotics are taken daily, with storage depending on the product, since some need refrigeration and others are shelf stable. Prebiotic fibre should be increased gradually with plenty of water, because going too fast is the usual cause of gas and bloating. Enzymes are taken with the meal they are meant to help. Supplements are not a substitute for medical advice. If you are pregnant or breastfeeding, take prescription medication, or are managing a health condition, check with your doctor or pharmacist before starting something new.

Frequently asked questions

What is the difference between probiotics and prebiotics?

Probiotics are live bacteria you swallow. Prebiotics are fibres that feed the bacteria already living in your gut. They work differently, and a product combining both is sometimes called a synbiotic. Prebiotic fibre is generally cheaper and is also abundant in ordinary foods such as onions, garlic, oats and legumes.

Does the number of billions matter?

Less than the strain. A high colony count of a strain with no relevant research is not better than a lower count of one that has been studied for your particular concern. Look for the full strain designation, the letters and numbers after the species name, rather than comparing billions.

Do probiotics need to be refrigerated?

It depends on the product. Some strains require refrigeration to stay viable, others are shelf stable, and the label will say. Shelf stable products are more practical for travel. What matters is the count at the end of shelf life rather than at manufacture, and better products state which they are quoting.

Should I take a probiotic with antibiotics?

It is a common recommendation, and Saccharomyces boulardii in particular has evidence for reducing antibiotic associated diarrhoea. The usual advice is to space the probiotic a couple of hours from the antibiotic dose. Raise it with the doctor or pharmacist who prescribed the antibiotic.

When should I see a doctor about gut symptoms?

Any persistent change in bowel habit, blood, unexplained weight loss, ongoing pain or symptoms that wake you at night warrant proper assessment rather than a supplement. Conditions like coeliac disease and inflammatory bowel disease need diagnosis, not guesswork.
