Buta-8™
Fibre for longevity
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 — not claims about Buta-8 itself, which hasn’t been clinically tested yet. Not a substitute for a fibre-rich diet.
Get the pacing right and you feed the butyrate relay steadily — without one big gas spike.
The spectrum below runs from earlier-fermenting to later-fermenting along your colon — profiles that overlap rather than sit in fixed zones.
Tap a fibre to follow its curve — or tap the tube to see the whole relay at once.
Fermentation activity
Illustrative, not measured — a design model based on established per-fibre fermentation behaviour, not a Buta-8 trial.
Different fibres, different jobs, fermenting across an overlapping spectrum. No single fibre covers the whole range — that’s the point of the spectrum. What that spectrum is designed to produce comes next.
When your gut bacteria ferment fibre, one of the short-chain fatty acids they make is butyrate — the main fuel the cells lining your colon run on. A matched spectrum of fibres is designed to keep that fermentation going, gently, across the day.
Diverse, fermentable fibres reach the colon largely intact — different structures for different bacteria.
Gut microbes break those fibres down into short-chain fatty acids, including butyrate.
Butyrate is the preferred fuel of the colonocytes — the cells that line and renew your colon.
This describes what butyrate is and how fibre is fermented — established science about the molecule and the ingredients. It is not a measured claim about Buta-8, which hasn’t completed its own trial.
Appetite runs low on a GLP-1, so fibre is one of the first things to slip. Buta-8 keeps diverse fibre coming on a gentle daily ramp — supporting comfortable regularity while you’re eating less. It’s a food, not a medicine; ease in and check with your clinician first.
Diverse fibre feeds the microbes that make butyrate — the fuel your gut lining runs on, and a molecule healthspan research keeps circling back to.

The simplest daily slot — for regularity, with a full glass of water.
For fullness and a gentler post-meal glucose rise.
Fine in the evening — just not right before lying down, and always with plenty of water.
Two habits that make it work
Always take it with a full glass. Psyllium swells into a gel — water is what makes it work, and what keeps it gentle.
Movement keeps things moving — a daily walk, a run, a game of tennis all count. Fibre is one piece, not the whole picture.
Build up to your level: under ~5 g of fibre a day now, start at half a scoop; around 5–15 g, one scoop; well above that, up to two scoops (morning and evening). Psyllium swells in water, so always take it with a full glass. Don’t take it if you have difficulty swallowing. Not a substitute for fibre-rich foods.
What to expect
Your gut needs a little time to get used to more fibre. Push too much too soon and you might feel gassy or full for a few days; ease in and that mostly settles. So Buta-8 is a habit you build, not a dose you jump straight into.
Week 1
Half a scoop in a full glass of water, once a day. Morning suits most people. A bit of extra gas or fullness in the first few days is normal — that’s your gut bacteria adjusting, not a sign something has gone wrong.
Week 2
If week one sat well, move to a full scoop. Keep the water up. Fibre needs water to do its job, and skimping on it is the most common reason fibre feels heavy.
Weeks 3–4
By now most people are on a full scoop and it has found its slot in the morning. Fibre is cumulative — the same modest amount every day matters more than any single big dose.
Ongoing
Consistency is the whole game. If a day feels off, drop back to half a scoop and build up again.
Everyone’s gut is different. If you have a medical condition or take regular medication, check with your doctor before you start.
Four things you can check for yourself — no hand-waving.
Ingredient evidence
Each fibre is chosen for its own body of human research — psyllium, inulin, acacia and resistant starch are among the most-studied fibres there are.
Full disclosure
No proprietary blend. The exact grams of every fibre are printed — we call it the Every-Gram Promise.
Testing
Each batch is checked for identity, purity, heavy metals and microbial safety before it ships.
The founding pilot
The pilot measures tolerability, regularity and adherence in real users — product learning, not a clinical efficacy trial.
Built from well-studied fibre ingredients and designed as a complete spectrum. The full Buta-8 formula is being evaluated through the founding pilot — so we talk about what the ingredients do, and never imply the finished blend is clinically proven.

Not a comparison table — just the questions worth asking of any daily fibre, ours included.
A viscous, gel-forming fibre is what supports comfortable, regular digestion.
Fermentable fibres are the substrate your microbiome actually uses — a single gel-forming fibre isn’t.
Different structures feed different bacteria and do different jobs. Variety by function beats one fibre alone.
You should be able to see exactly how much of each fibre you’re getting — no proprietary blend.
A gentle ramp — starting at half a scoop — is what makes a daily fibre something you can actually keep.
From the founder
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.
— Ravi, founder, Akunka
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 it’s a sensible daily fibre if you are. Buta-8 is a food, not a medicine. Appetite runs low on a GLP-1, so fibre is one of the first things to slip, and a gentle, diverse, gel-forming fibre supports comfortable regularity while you’re eating less. Take it with a full glass of water, ease in from half a scoop, and — as with any supplement alongside medication — check with your clinician first.
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.
