How GutSupp works
Think of your gut as a garden. GutSupp is like fertiliser for the good bacteria already growing there.
Feed
GutSupp’s prebiotic fibre reaches your large intestine, where it becomes food for bacteria already living there.
Create
As your gut bacteria use this fibre, they create compounds called short-chain fatty acids, including acetate and butyrate.
Nourish
Butyrate provides energy for the cells lining your colon. Feeding your bacteria helps fuel this lining, too.
One of the most clinically studied prebiotics of its kind
The ingredient and the label
Get to know the prebiotic fibre in GutSupp, how it differs from live cultures, and the amounts used in research.
GutSupp contains Bimuno® Powder, including galacto-oligosaccharides, or GOS, derived from lactose (milk), and galactose (milk). GOS is a carbohydrate ingredient.
Products marketed as probiotics contain live microorganisms. To make a useful comparison, look at the actual formulation and the evidence for that particular product.
A paper may report the weight of a commercial powder or the amount of GOS within it. Different preparations can have different compositions. We preserve the paper’s units instead of treating those figures as interchangeable.
Parker 2026 studied 3.65 g of preparation providing 2.75 g of active GOS.

More on the prebiotic fibre in GutSupp and the research behind it.
hello@gutsupp.comNo. The laboratory models use donor samples in controlled experiments. They can help researchers investigate interactions and measurements, but they do not directly measure how a person feels after taking a product.
GutSupp contains Bimuno® GOS, a type of fibre used as food by selected gut bacteria.
They investigate different research questions and can use different preparations. A powder’s total weight and its active GOS content are different measures. Follow the current pack directions rather than copying an amount from a paper.
No. Evidence needs to match the particular strain, formulation, amount and population. A study of one product cannot establish that every product in a category works in the same way.
