How to use?

Take one sachet daily and stir it into any cold or room-temperature food or drink - coffee, smoothies, yoghurt or water. It’s unflavoured, heat-stable and dissolves easily, so it fits seamlessly into your routine. Consistency is key, so take it at any time of day, morning or evening, as long as you take it daily.

Product Benefits

Supports digestive comfort and regularity by nourishing beneficial gut bacteria, helping to restore balance in the gut. A healthier gut may also support better sleep through the gut-brain connection, strengthen immune function, and contribute to improved daily energy and overall wellbeing.

What makes GutSupp different?

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.

Ingredients

GutSupp is made of Bimuno® Powder (Galactooligosaccharides (GOS) derived from lactose (milk), galactose (milk). Allergens are marked in bold.

The Bimuno technology is a blend of non-digestible Galactooligosaccharides (GOS) that passes through the upper gastrointestinal tract until it reaches the colon, where it enhances the production and activity of beneficial gut bacteria.

3 Clinical Trials That Show Exactly What GutSupp Does
PROOF, NOT PROMISES

3 Clinical Trials That Show Exactly What GutSupp Does

120+ studies and 20+ clinical trials. GutSupp's active ingredient has been studied for over 20 years. Here are three of the key trials - in plain English:

🔬 Bloating, wind & stomach pain reduced in 1 week

In a clinical trial with 83 adults, participants reported significantly less bloating, flatulence and abdominal discomfort after just 7 days. Peer-reviewed. Independently conducted.

🔬 Participants slept better and felt less stressed

An Oxford University study with 45 volunteers found lower cortisol, reduced anxiety responses and measurably improved sleep. Your gut and your brain are more connected than you think.

🔬 IBS sufferers reported dramatically better quality of life

In a real-world study of 1,170 people with gut issues, those reporting a significant negative impact on their quality of life dropped from 100% to just 19% after using this ingredient.
WHY NOTHING ELSE WORKED

If You've Tried Probiotics and Felt Nothing - This Is Why...

❌ Probiotics add foreign bacteria - most are dead before they reach your lower gut.

✅ GutSupp's Bimuno® GOS selectively feeds Bifidobacteria: the specific strain linked to bloating relief, better sleep, and immune function.

WHY GUTSUPP IS DIFFERENT

Probiotics Add Bacteria. GutSupp Feeds Yours.

GutSupp is a prebiotic, not a probiotic. Instead of trying to add foreign bacteria (that usually die in transit), it feeds the good bacteria you already have. Specifically, it increases your bifidobacteria - the strain linked to digestive comfort, immune function, and even sleep.

Factor Typical Probiotic GutSupp
Survives stomach acid Often not ✓ Yes

Feeds existing bacteria No ✓ Yes

OUR PROMISE TO YOU

Not Sure? Try It For 60 Days.

⚠️Heads up for your first week: Some people notice mild changes in digestion in the first few days - more wind or a slight change in frequency. This is completely normal. It means the prebiotic is starting to shift your gut bacteria, which is exactly what it's supposed to do. It settles within a few days.
