If you live with IBS or a sensitive gut, finding a protein powder that doesn't leave you bloated can feel impossible. Most mainstream powders are packed with whey, inulin, chicory root fibre or polyol sweeteners — all common IBS triggers. The good news: low FODMAP protein powder exists, and it works.
Here's our straightforward 2026 guide to choosing the best low FODMAP protein powder in the UK — what to look for, what to avoid, and where That Protein fits in.
What makes a protein powder low FODMAP?
FODMAPs are fermentable carbohydrates that can trigger bloating, wind and discomfort for people with IBS. A genuinely low FODMAP protein powder avoids high-FODMAP ingredients such as inulin, chicory root, added fructose and polyol sweeteners (like sorbitol and maltitol), and uses gentle, well-tolerated protein sources.
Certified vs simply "low FODMAP"
There's an important difference. Some products are independently FODMAP Friendly certified (lab-tested and verified); others are just formulated to be low FODMAP. Certification gives you extra peace of mind. That Protein is the UK's only FODMAP Friendly certified vegan protein brand — our Blissful Brown Rice & Raw Cacao and Double Choc Protein Porridge are both certified.
What to look for
- Low FODMAP, ideally certified — tested and verified, not just "gut-friendly" marketing.
- Vegan, plant-based protein — brown rice and pea protein are gentle and well tolerated.
- No inulin, chicory or polyols — the usual hidden triggers.
- No artificial sweeteners or gums — clean, simple ingredients.
- Made with organic ingredients — quality you can trust.

Frequently asked questions
Is plant protein better for IBS? For many people, yes — whey and casein (dairy proteins) can be harder to tolerate. Gentle plant proteins like brown rice and pea are a popular choice.
Will it stop my bloating? Everyone's gut is different, but removing common FODMAP triggers is a sensible first step. Always introduce new foods gradually.
