Fibre Supplements

Most of us know we should be eating more fibre — but most of us aren't. The NHS recommends 30g of fibre per day, yet the average UK adult gets closer to 18g. That gap is one of the main reasons fibre supplements have become such a popular part of everyday wellness routines: they offer a simple, measurable way to top up what's missing from the diet.

Fibre supplements aren't a single product — they're a category of different ingredients, each working in a slightly different way. Psyllium husk (sometimes labelled ispaghula) is one of the most established, used in clinical practice for decades and recommended by NICE for IBS management. Inulin, derived from chicory root, is a prebiotic fibre that feeds beneficial gut bacteria. Glucomannan, from konjac root, has an exceptional capacity to absorb water and is popular for satiety-focused routines. Methylcellulose is a gentler, non-fermenting option often chosen by those who find other fibres cause bloating.

Key Things To Know

• Fibre type matters — psyllium, inulin and glucomannan all work differently and suit different needs
• Hydration is essential — most fibre supplements, especially psyllium, need to be taken with plenty of water
• Start low, build up — sudden increases in fibre intake commonly cause temporary bloating or gas
• Formats vary — capsules, powders and chewable tablets all deliver fibre differently and suit different routines
