Who it’s for
Who Buta-8 is for.
Most of us miss the daily fibre target — one scoop closes the gap.
Eating less often means less fibre — Buta-8 helps keep you regular, gently.
For regularity, fullness, and a better-fed gut — gently.
For the healthspan crowd who actually reads the citations.
Also for: athletes, daily-habit buyers, and anyone swapping sugary snacks for functional nutrition.
The gap
The fibre problem
In fibre trials, 36–44% quit within three months1 — rarely from willpower. Usually it’s one of these four things.
You take fibre to feel lighter and end up bloated and gassy by the afternoon. It’s the top reason people give up.2
Your gut thrives on a range of plants. The same single fibre, day after day, gives it none of that variety.
You can’t really see what you’re taking — or how much of it. You’re trusting a label that doesn’t add up.
Chalky, gritty, or too sweet. A daily drink you don’t enjoy isn’t one you’ll keep reaching for.3
1 36–44% had stopped within three months — Bijkerk et al., BMJ 2009 (incl. a placebo arm — staying on any daily habit is hard). 2 Bonnema et al., 2010; van der Schoot et al., AJCN 2022 (fibre raises flatulence vs placebo). 3 Hosseininasab et al., 2025 (texture as an adherence barrier).
What it does for you
Fibres paced fast→slow and buffered with viscous psyllium, so fermentation spreads out instead of arriving in one gassy spike.
Six plant fibres doing four jobs — feeding a whole range of gut bacteria, not just one.
Every gram of every fibre named on the pack. No proprietary blend.
Light, low-calorie, lightly sweetened with monk fruit — made to keep up every day.
Also: the viscous fibre helps you feel fuller, and supports a gentler post-meal glucose rise.
Gentle by design
Fast-fermenting fibres taken on their own are a common reason people quit fibre — the bloat.
Buta-8 pairs them with viscous psyllium, kept at or above the fast-fermentable load, to slow and spread out fermentation across the gut. The principle is published: psyllium taken with inulin produces less gas than inulin alone.1

Fibre diversity
Different fibres do different jobs. Most products use one. Buta-8 is built on four.
Forms a gel, slows digestion
Fuel for your microbiome
Feeds the beneficial species
Plant-compound diversity

Most products lean on one fibre. Buta-8 brings four — plus plant polyphenols.
Marks reflect representative products by category; formulas vary, so check each product’s Supplement Facts. Single-fibre = e.g. psyllium; prebiotic blends typically use resistant starch / guar (not psyllium); greens powders are polyphenol-rich but higher-calorie (≈40–50 kcal) with little fibre. The psyllium-tolerability evidence is cited under Gently by design, above.
Why these six
Fibre isn’t one thing. What a fibre does depends on how it ferments — and which bacteria it feeds. So each one here earns its place doing a job the others can’t.
A fibre’s job ≈ how fast it ferments × how completely × which microbes it feeds
— and many butyrate-making bacteria borrow acetate from the fast fermenters. The fibres aren’t a list. They’re a relay.
This is ingredient-level formulation logic. The finished blend hasn’t been clinically shown to raise butyrate in people — that’s what our pilot is for.
Resistant starch
Ferments slowly and deep into the colon, and is among the most butyrate-favouring of the fibres — it feeds the bacteria that make butyrate.
Chicory inulin
Ferments fast and makes acetate — the raw material those butyrate-makers borrow. Long-chain inulin, not the gassier short-chain kind.
Psyllium husk
Barely ferments. Its gel is there to make a fermentable blend easier to tolerate — and it’s the largest single fibre in Buta-8, by design.
Four working fibres, two polyphenol botanicals, balanced so it stays gentle enough to take every day. That’s the difference between a longer ingredient list and a designed system.

When to take it
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.
New to added fibre? Start with half a scoop for the first few days, then build up. Psyllium swells in water, so always take it with a full glass. Don’t take it if you have difficulty swallowing.
From the founder
I got obsessed with fibre when I realised it does far more than keep you regular. It’s studied for things most people never connect to fibre: post-meal blood sugar, fullness, even the cell-cleanup and inflammation pathways researchers are still mapping. That rabbit hole is what started Buta-8.
The deeper I went, the clearer one thing got: diversity matters more than dose. Your gut doesn’t want a lot of one fibre, it wants a range. But almost everyone who tries fibre quits for the same reason. The bloat.
So I built the blend I’d actually keep taking: diverse, paced to be gentle, easy to drink every day. It settled my own digestion without the bloating, and the mechanisms behind it are what keep me hooked.

Questions
Bloating usually comes from fast-fermenting fibres taken all at once. Buta-8 is paced across the fermentation spectrum and balanced with viscous psyllium to be gentle — and we tell you to start with half a scoop and build up.
Four fibres and two plant botanicals, every gram named — no proprietary blend. See the full recipe →
One 8 g scoop in 220 ml of water, once a day. New to fibre? Start at half a scoop for week one.
Plant-based, no fillers, no added sugar — lightly sweetened with monk fruit.
