Buta-8™
Fibre for longevity
You already know the gap. Here's what you don't.
Smart Diversity, made visible: fibres chosen across three complementary layers.
Gel and bulk — how fibre holds water and keeps you regular
Fermentation — the fibres your gut bacteria feed on
Whole-plant variety — pulp, polyphenols and minerals
Tap a fibre — each does a different job
Simple fructose chains that ferment fast and early — a strong, rapid prebiotic for Bifidobacteria. Because it ferments quickly it can produce gas, so it’s best built up gradually.
Resists digestion and reaches the colon intact, where it’s among the more butyrate-favouring fibres — feeding the bacteria that produce butyrate, the short-chain fatty acid that fuels the cells lining your colon. It ferments gradually, so it tends to be gentle on gas.
Soluble but complex and highly branched, so bacteria break it down slowly — a more gradual fermentation profile rather than a burst. One of the best-tolerated fibres for sensitive stomachs.
Swells into a thick gel that works both ways — softens hard stool, firms up loose. It’s primarily gel-forming and less rapidly fermented than the others, so it supports regularity without a sudden gas spike. Its viscosity is the most-studied of these fibres in human trials.
Whole fruit pulp with a naturally balanced mix of roughly half soluble, half insoluble fibre — plus polyphenols, vitamin C, potassium and magnesium that isolated fibre powders lack.
Soluble pectin forms a gel that slows how fast carbohydrates digest; insoluble cellulose adds bulk. Its deep-purple anthocyanins are polyphenols studied for antioxidant activity. (Metabolic effects are largely preclinical — mechanism, not a product claim.)
New to fibre? What fibre does in your gut
Fermentable fibres are food for the microbes in your gut. That’s what a prebiotic is.
Fermentation produces short-chain fatty acids that nourish the cells lining your colon.
Soluble, viscous fibre adds bulk and supports comfortable, regular digestion.
Fibre adds bulk and slows digestion, which can help you feel full between meals.
Independent, ingredient-level evidence for dietary fibre. These are not claims about Buta-8 itself, which hasn’t been clinically tested yet. Not a substitute for a fibre-rich diet.

On a GLP-1 you’re eating less, so your gut gets less of the fibre it runs on, right when it needs it most. Buta-8 keeps diverse daily fibre going and supports regularity. We won’t pretend to be Ozempic; we’re the fibre your gut needs while it works.
Diverse fibre feeds the microbes that make butyrate, the fuel your gut lining runs on and a molecule healthspan research keeps circling back to.
Also for: athletes, daily-habit buyers, and anyone swapping sugary snacks for functional nutrition.
Six questions. Ours included.
| The question | Buta-8 | A typical fibre powder |
|---|---|---|
| How many kinds of fibre? | Four, plus two whole fruits | Usually one |
| How far down does it work? | Start to end of the colon | Mostly the first stretch |
| Are the grams of each ingredient shown? | Every one, on the pack | Rarely — often a blend |
| Is there a gel-forming fibre for regularity? | 3.5 g psyllium, the largest ingredient | Often none |
| Is it built to ease in? | Half-scoop first week, by design | Full dose from day one |
| Is every batch tested? | Identity, purity, heavy metals, microbes | Varies |

I got into fibre when I realised how much it does beyond keeping you regular, right down to how gut bacteria turn it into the fuel our colon cells run on. The deeper I went, the clearer one thing got: dose gets you started, but design is what makes a blend work. Your gut doesn’t want a lot of one fibre. It wants a range, paced to be gentle.
So I built the blend I’d actually keep taking: diverse, easy on the day, and honest about every gram.

It can, if you start too fast. That’s true of any fibre, and it’s the whole reason we build it up slowly. Start at half a scoop in week one, keep the water up, and most first-week gas or fullness settles as your gut bacteria adjust. The blend is also designed to be gentler than a single fermentable fibre: viscous psyllium is kept at or above the inulin, and psyllium taken with inulin produces less gas than inulin alone (Gunn et al., Gut 2022).
Half a scoop a day for week one, then work up to a full scoop if that sat well. Always take it in a full glass of water — fibre needs water to do its job.
Morning is the simplest slot for most people, on an empty stomach with plenty of water. What matters more than timing is taking it consistently.
Psyllium is excellent — it’s the backbone of Buta-8. But it’s good at one job, mainly bulk and regularity; it doesn’t do much to feed the bacteria deeper in your gut. Buta-8 keeps the psyllium and adds the fibres that cover the jobs it can’t. See the spectrum →
Different fibres have different structures, so they feed different bacteria and do different jobs — gel and bulk, earlier and later fermentation, plant variety. A range of complementary fibres covers more than any single one.
The individual ingredients have published human evidence; the finished Buta-8 blend has not completed its own trial yet. The founding pilot is where we gather real-world learning on tolerability, regularity and adherence — product learning, not a clinical efficacy claim.
Yes — and fibre matters more on a GLP-1, not less. Eating less means your gut gets less of the fibre it runs on. Buta-8 keeps diverse daily fibre going and supports regularity — and there’s real biology behind it: your gut bacteria turn fibre into the signals that trigger your body’s own GLP-1, the same pathway your medicine works on. It’s food, not a drug — it won’t replace anything your medicine does. Check with your clinician, start at half a scoop with plenty of water, and build up.
Light and lightly sweetened with monk fruit, not chalky or overly sweet. Psyllium gels quickly, so shake it and drink it promptly rather than letting it sit.
No — it includes chicory inulin, which is a FODMAP. If you’re in a low-FODMAP elimination phase or your clinician has put you on that plan, talk to them first.
Most Indian plates are strong on one kind of fibre and light on the rest — plenty of the bulking kind, much less of the fermentable kind your gut bacteria prefer. Buta-8 isn’t here to replace your food; it fills the part of the fibre gap a good thali usually leaves behind, in one scoop you don’t have to think about.
Don’t take it if you have difficulty swallowing, since psyllium swells in water. If you have a gut condition or take regular medication, check with your doctor before starting. It’s not a substitute for a varied, fibre-rich diet.
