About this one

Most of Us Are About 10g of Fibre Short. This Closes the Gap.

The UK recommends 30g of fibre a day, and most adults manage about 20g. The Happy Gut Super Pre-Biotic Blend is a simple, high-fibre blend of two natural ingredients: milled British hemp seed and chicory root.

At Functional Drinks Club, the basics come first. This is one of the things Kev adds to his routine every day.

What's Inside

Milled Hemp Seed - Around 50% insoluble fibre, plus 14% plant-based protein. Grown regeneratively in Britain, carbon-neutral by nature. This is hemp working the way it was always meant to.

Chicory Root - 16% soluble fibre in the form of inulin, one of the most studied fibres there is.

No preservatives. No anti-caking agents. No flavourings or sweeteners. Just clean, natural fibre that's vegan, dairy-free, and gluten-free.

Why You'll Love It

Fibre is the Phil Collins of nutrition: not glamorous, deeply underrated, and secretly on every great album. Everyone's banging on about protein while fibre sits in the corner, quietly being the thing most of us are missing.

This is the laziest possible fix. One spoon, stirred into porridge, a smoothie or your morning kombucha, and you're 10g closer to the 30g. No sweeteners, no flavourings, no 14-ingredient "gut glow powder" that costs more than your car insurance. Two ingredients. Job done.

How Kev Takes It

"A spoon of this goes in my morning smoothie every day. I started with half a spoon and built up over a couple of weeks, because going from zero to loads of fibre overnight is a rookie error. Fibre's the boring basic almost everyone's short on, me included, and the research on it is some of the most solid there is. I've written up the bits that convinced me on my Cover the Basics page."
- Kombucha Kev, Functional Drinks Club

How to Use

Mix one serving into water, a smoothie, porridge or your morning kombucha. It's a daily habit, not a one-off. If you're new to extra fibre, start with half a serving and build up over a couple of weeks, and drink plenty of water with it.

Format: Fine milled powder | Unflavoured | Mixes clean | Vegan | Dairy-free | Gluten-free

Want the science? Here's why fibre is one of Kev's four everyday basics, with the research behind it.
