The gut is home to trillions of microorganisms – the gut microbiota – and what we eat helps shape this community. Two groups of foods are often mentioned: those rich in certain types of fibre, and fermented foods containing live cultures.
What is the difference?
- Dietary fibre – especially certain types found in plant foods – is not digested in the small intestine and reaches the large intestine, where gut bacteria use it as food.
- Live cultures are live microorganisms found naturally in fermented foods and in some food supplements.
Foods rich in fibre
Onions, garlic, leeks, asparagus, artichokes, chicory, bananas, oats, rye, pulses and mushrooms. UK guidelines recommend 30 g of fibre a day for adults – most people eat much less.
Fermented foods with live cultures
Yoghurt, kefir, sauerkraut, kimchi and kombucha. Fermented foods have been part of human diets for thousands of years.
Mushrooms as a source of fibre
Lion's Mane (Hericium erinaceus) is an edible mushroom that contains protein, minerals such as zinc and selenium, and fibre – including beta-glucans and chitin. It also contains characteristic compounds called hericenones and erinacines.
Our products

If you have persistent digestive symptoms or changes in your bowel habits, please speak to your GP.
Food supplements should not be used as a substitute for a varied, balanced diet and a healthy lifestyle.
