The average UK adult eats around 18g of fibre a day against the NHS recommendation of 30g. FibreFix provides a minimum of 513mg of dietary fibre per capsule — both soluble and insoluble — from eleven naturally high-fibre foods, every dose declared. No powder to mix, no taste.

Eleven Fibre Sources, Not One

Most fibre supplements are psyllium and nothing else. Psyllium is the lead ingredient here at 500mg per capsule, but it sits alongside rhubarb, broccoli, flaxseed, sugar beet fibre, prune, fenugreek, apple pectin, fig, carrot and fennel seed.

These foods supply more than roughage — they provide cellulose, pectin, hemicellulose, lignin and gums, which behave differently from one another in the gut. That is the argument for a blend over a single fibre.

Sugar beet fibre carries the authorised claim for an increase in faecal bulk, and it works two ways: the insoluble components absorb water in the large intestine, while the soluble components are fermented by gut bacteria, increasing bacterial mass.

How Other UK Fibre Supplements Compare

Fybogel — psyllium sachets, pharmacy standard. Effective and cheap, but a single fibre you have to mix and drink, with a texture many people dislike.

Psyllium husk capsules — one ingredient. Convenient, but psyllium alone with none of the fruit, vegetable or seed fibres.

Inulin or FOS powders — soluble only. Prebiotic fibres that feed gut bacteria, but they don't provide the insoluble bulk that psyllium and sugar beet do.

What's in Every Capsule — All Eleven Declared

EU-authorised claim:

  • Sugar beet fibre — 60mg · contributes to an increase in faecal bulk

Total dietary fibre — minimum 513mg per capsule, soluble and insoluble.

The eleven fibre foods:

  • Psyllium husk — 500mg · Plantago ovata · the lead fibre, and the most researched bulk-forming fibre
  • Rhubarb — 450mg equivalent · Rheum palmatum
  • Broccoli — 75mg equivalent · Brassica oleracea
  • Flaxseed — 70mg · Linum usitatissimum · source of mucilage and lignans
  • Sugar beet fibre — 60mg · Beta vulgaris · carries the authorised faecal bulk claim
  • Prune — 50mg equivalent · Prunus salicinas · the traditional fruit for regularity
  • Fenugreek seed — 40mg equivalent · Trigonella foenum-graecum · soluble mucilaginous fibre
  • Apple pectin — 20mg · Malus pumila · classic soluble fibre
  • Fig fruit — 20mg equivalent · Ficus carica
  • Carrot — 5mg · Daucus carota
  • Fennel seed — 5mg equivalent · Foeniculum vulgare · traditional carminative

How to Take It

Take 1 or 2 capsules, one to three times per day, or adjust intake as required. Always take with a minimum of 250ml of water.

Ideally take before an evening meal, or split your total intake over two meals. If you're new to fibre supplements, start at the lower end and build up — increasing fibre too quickly commonly causes wind and bloating.

For a powder with glucomannan at the EFSA weight-loss claim dose, BioSlim. To support gut flora alongside, BioTic 4 Billion.

Is This You?

  • You're well short of the NHS 30g daily fibre recommendation — as most UK adults are
  • You want a capsule rather than mixing and drinking a gritty powder
  • You'd rather have eleven fibre foods than psyllium alone
  • You need halal and kosher approved fibre — Fybogel carries neither
  • You do not have a mustard or sesame allergy

Questions We Get Asked

How much fibre do I actually need?

The NHS recommends 30g of fibre a day. Most UK adults get around 18g. Each FibreFix capsule provides a minimum of 513mg, so it is a top-up to a fibre-rich diet rather than a replacement for one — vegetables, pulses, wholegrains and fruit should still do most of the work.

What's the difference between soluble and insoluble fibre?

Insoluble fibre absorbs water and adds bulk. Soluble fibre forms a gel and is fermented by gut bacteria. Sugar beet fibre does both, which is why it carries the authorised faecal bulk claim. This blend provides both types across eleven different foods, along with cellulose, pectin, hemicellulose, lignin and gums.

Does it contain any allergens?

It may contain traces of mustard and sesame — the supplier declares both. If you have a mustard or sesame allergy, this product is not suitable for you.

How is it different from BioSlim?

FibreFix is a capsule with eleven fibre foods and no added actives. BioSlim is a powder containing glucomannan at 1.05g per serving — the dose that meets the EFSA weight loss claim — plus live cultures, L-glutamine and digestive herbs. Choose FibreFix for convenient daily fibre; choose BioSlim if you want the glucomannan claim.

Food supplements should not replace a varied diet or healthy lifestyle. May contain traces of mustard and sesame. Always take with at least 250ml of water. Consult your GP before use if pregnant, breastfeeding, taking prescription medication, or managing a diagnosed bowel condition.

100% Psyllium Husk

A soluble dietary fibre from Plantago ovata seeds. Forms a gel that supports normal bowel regularity, a feeling of fullness, and a healthy gut environment. EFSA-approved for its contribution to normal bowel function.

Before an evening meal, or split over two meals — always with at least 250ml of water.
