Supplements for Gut Lining and Digestive Health
“Leaky gut” describes increased intestinal permeability, a research term rather than a standard medical diagnosis. People who look for gut-lining support usually try probiotics, prebiotics, fibre or colostrum. Our top picks are three probiotics, a bovine colostrum tablet and a fibre mix. Ongoing diarrhoea, pain, weight loss or food reactions need a doctor to find the cause.

Why Are These Products Included?
- 4Life Pre/O Biotics delivers 1 billion CFU of five researched probiotic strains plus prebiotics. Its label lists milk, egg, soy, fish and tree nuts as allergens.

How to Choose
Change one thing at a time. Start with a probiotic and a fibre-rich diet, give it four weeks, then decide about colostrum. Cut back on alcohol, ultra-processed foods and unnecessary painkillers (NSAIDs), which can irritate the gut lining. Keep a symptom and food diary to share with your doctor.
What Is “Leaky Gut”?
The gut lining lets nutrients through while keeping harmful substances out. Researchers use “increased intestinal permeability” to describe a lining that lets more through than normal, which is seen in coeliac disease, inflammatory bowel disease and some infections. Online, the term is often used for a wide range of symptoms such as bloating, fatigue or skin problems, which have many possible causes.
When to See a Doctor
See a doctor for persistent diarrhoea, blood in the stool, unplanned weight loss, anaemia, severe or recurring abdominal pain, fever, or suspected food allergy or coeliac disease. Get tested before removing food groups such as gluten from your diet.
What Supplements Can and Cannot Do
Probiotics and fibre support day-to-day digestive balance for many people, but results vary and there is no proven supplement treatment for “leaky gut”. Supplements cannot diagnose or treat gut disease. Medical testing is the way to find the cause of persistent symptoms.
Precautions and Interactions
- Probiotics and colostrum: ask a doctor first if you have a weak immune system or serious illness.
- Colostrum and 4Life Pre/O Biotics contain milk. 4Life Pre/O Biotics also contains egg, soy, fish and tree nuts. Avoid them if you are allergic.
- Take fibre with plenty of water, and at least two hours apart from medicines.
- Pregnant or breastfeeding women should ask a doctor before use.
- Stop use if symptoms get worse.
