When will I notice results?

Many people notice improvements in bloating and digestive comfort within the first 7 days of daily use. Because everyone’s gut microbiome is different, results can vary, with some people noticing more significant improvements after 2–4 weeks of consistent use.

How do I take GutSupp daily?

Mix one sachet daily into hot or cold drinks, yoghurt, porridge or other food. GutSupp is tasteless and easy to mix. Follow the directions on your pack.

If you have a sensitive gut or experience significant gas after starting, begin with half a sachet a day for the first 7 days, then increase to one sachet daily as tolerated.

How much is shipping?

Free UK delivery on subscription orders. £3.50 for delivery on single purchase orders. Orders are typically dispatched within 24 hours.

Product Benefits

GutSupp is backed by over 100 scientific publications and 20+ human trials, making it one of the most studied prebiotics of its kind. It works quickly, increasing beneficial gut bacteria in as little as 7 days, while selectively feeding the bacteria your gut actually needs - not everything indiscriminately. Plus, it’s effortless to use, with a tasteless, heat-stable formula that fits easily into your daily routine.

Everything you need to know before starting GutSupp

Learn how GutSupp works, what to expect and why thousands take it daily for digestive comfort and gut balance.

Many people begin noticing improvements in digestive comfort, bloating and overall gut balance within the first 7 days of daily use. Clinical studies on Bimuno® GOS have shown increases in beneficial gut bacteria within this timeframe.

Because everyone’s gut microbiome is different, results can vary. Some people notice changes sooner, while others experience more noticeable improvements with continued daily use over 2–4 weeks. For best results, GutSupp should be taken consistently every day.

GOS stands for galactooligosaccharides, a type of prebiotic. GutSupp contains Bimuno® GOS, which feeds beneficial bacteria already living in your gut.

Gutsupp is derived from lactose (milk) so it is suitable for vegetarians and is also gluten-free. Gutsupp is informed sport certified so it is also suitable for athletes.

Prebiotics work much like fertilisers in the garden and feed the "good bacteria" in our gut. Therefore, introducing prebiotics and probiotics into your daily lifestyle can stimulate your overall gut health and well-being. Bimuno and all food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle.

GutSupp is a prebiotic fibre powder that has been scientifically proven to feed & stimulate the growth of beneficial bifidobacteria in your gut within just 7 days. Helping to promote optimal gut health and further whole body benefits.

Gutsupp is a prebiotic. Prebiotics can be thought of as the food for the 'good types of
bacteria in your gut such as bifidobacteria that help balance your microbiome.
Probiotics are 'live' bacteria. The issue with many probiotic supplements is that they
don't reach your gut intact and if they do, lack the food they need to thrive and be
effective.
