Fibre is the new protein.
This is what doing it properly looks like.
A clinically dosed synbiotic — three fibres, each doing a different job, plus a live culture built to actually survive the journey to your gut. One neutral scoop a day.
Three fibres.
One live culture. Working together.
Including a live culture heat-stable enough to survive shelf storage, hot drinks and stomach acid — built to actually arrive where it's needed.
A complete formula,
not a single ingredient.
PHGG feeds good bacteria at a full clinical dose — 5g, the same amount used in research, not a token sprinkle. Acacia fibre broadens that support to a wider range of bacteria. Psyllium husk handles gentle daily bulking.
Add a live, heat-stable culture on top, and that's a synbiotic — three fibres and a probiotic working together in one neutral daily scoop.
Fibre is the new protein
Most people fall well short of their daily fibre target — it's become one of the most talked-about nutrition gaps, the same way protein was a few years ago. Getting a genuine, well-formulated dose in daily is the actual challenge.
One extra scoop, no new ritual
Seed cycling already gives you fibre, healthy fats and key minerals from four seeds. Gut Fibre adds a full clinical dose of prebiotic fibre and a live culture on top — stirred into the same daily scoop, no extra ritual to build.
Four ingredients.
Nothing filler.
PHGG (Sunfiber®)5g — full clinical dose
The gentle, prebiotic fibre that feeds good bacteria. Dosed at the same 5g used in clinical research, not a token sprinkle just to put the name on the pack.
Organic acacia fibre
A second prebiotic fibre, feeding a broader range of gut bacteria so the support isn't reliant on one fibre type alone.
Organic psyllium husk
A gentle bulking fibre for daily regularity and comfort.
Bacillus coagulanslive culture
Heat-stable and spore-forming, so it survives shelf storage, hot drinks and stomach acid to actually arrive where it's needed. This is what makes it a synbiotic, not just a fibre blend.
What's a synbiotic?
A prebiotic (fibre that feeds good bacteria) and a probiotic (a live culture) together in one product, each supporting the other — rather than just one or the other on its own.
One scoop.
Neutral taste, any drink.
Add one scoop
Straight from the pouch — no measuring.
Stir into anything
Water, a smoothie, yoghurt, or alongside your seed cycling scoop — neutral taste, won't change the flavour.
New to fibre supplements?
Start with half a scoop and build up over a few days to let your gut adjust.
Questions, answered
What makes this a "synbiotic" rather than just a fibre powder?
It combines three fibres — PHGG at a full clinical dose, acacia fibre, and psyllium husk — with a live, spore-forming probiotic culture. The fibre and the culture work together, which is what makes it a synbiotic.
Will this upset a sensitive gut?
It's formulated to be low FODMAP friendly. If you're new to fibre supplements generally, start with half a scoop and build up over a few days.
Does the live culture actually survive?
Bacillus coagulans is spore-forming, meaning it's built to withstand heat, shelf storage and stomach acid — unlike many probiotic strains that break down before they arrive.
Can I take this alongside seed cycling and Sea Buckthorn?
Yes — it's phase-independent, so it works alongside your Phase 1 or Phase 2 scoop, and alongside any other add-ons, any day.
