Not All Fibre Is Equal
Powered by premium prebiotic sources, this soluble fibre supplement is designed to nourish your microbiome without triggering digestive discomfort.
Feel the Results
Fibre is underrated, but the benefits cannot be overstated.
Feeds gut microbes
Gut bacteria break down the fibres to make compounds that help digestion and support the immune system.
These compounds include short-chain fatty acids (SCFAs), which are widely studied for their role in gut health.
Supports gut transit
Keeps things moving through your gut, helping you stay regular.
Long-term results
With regular use, fibre helps your gut adjust over time, leading to steadier digestion and fewer ups and downs.

FAQs
Why does prebiotic fibre matter?
Prebiotic fibre is a type of fibre that your body can’t digest, but your gut bacteria can – it acts as “food” for the helpful microbes in your colon. When these bacteria ferment prebiotic fibres, they produce short‑chain fatty acids (like butyrate, acetate and propionate) that help fuel the gut lining, reduce inflammation and support a healthy gut barrier.
A regular intake of prebiotic fibre has been linked with better digestive comfort, improved stool regularity and a more diverse, resilient microbiome. Studies also associate prebiotic intake with benefits such as improved mineral absorption, healthier cholesterol and blood sugar markers, and support for weight management over time.
In short, getting enough prebiotic fibre helps keep your gut ecosystem in balance, which is increasingly recognised as a foundation for overall health and wellbeing
What’s the difference between prebiotics and probiotics?
Prebiotics and probiotics work together for gut health, but they are not the same thing.
Probiotics are live beneficial bacteria found in certain foods (like yoghurt, kefir, sauerkraut) and supplements that can help top up or rebalance the microbes in your gut.
Prebiotics are special types of fibre that your body can’t digest but your gut bacteria can – they act as “food” for the good bacteria you already have. Put simply, probiotics add more good bacteria, while prebiotics feed and strengthen them so they grow and do their job properly.
For most people, a fibre‑rich diet that includes plenty of prebiotic fibres is a sustainable way to support a healthy microbiome, with probiotic foods or supplements layered on when needed (for example after antibiotics, or on medical advice).
Will this cause bloating or gas?
Most people find Fibre Foundation very gentle to tolerate. It’s built around Sunfiber® (PHGG), a well‑researched, low‑FODMAP soluble fibre that ferments slowly, which helps reduce the sudden gas and bloating you might get from harsher fibres. If your gut is very sensitive, start low (¼–½ serving) and increase gradually so your digestion has time to adjust.
How is this different from psyllium / typical fibre supplements?
Typical fibre supplements (like psyllium husk or inulin blends) often work by bulking and can ferment quickly, which may lead to bloating or cramping for people with sensitive guts. Fibre Foundation is built around Sunfiber® (PHGG), a clinically studied, low‑FODMAP prebiotic fibre that ferments more slowly and is generally well tolerated, even in those who struggle with standard fibre supplements. Instead of a big “bulk” hit, this gentle daily fibre supplement focuses on soluble fibres that steadily feed your gut bacteria, supporting regularity and long‑term gut health without making a fuss.
How long before I notice a difference?
This is designed for gradual change, not immediate relief.
Some people notice changes within weeks; for others it takes longer. Consistency matters more than speed.
