Who this guide is for
UK shoppers who want a higher-protein supplement that is friendlier to sensitive digestion — for example, people who are following a low-FODMAP eating pattern, or who simply do not get on with whey concentrate.
How we picked
We compared each product on:
- Whey type — isolate and hydrolysate generally contain less lactose than concentrate.
- Sweeteners — we flag polyols (sorbitol, mannitol, xylitol) and high-dose inulin or chicory root, all of which are commonly avoided on a low-FODMAP pattern.
- Price per serving — calculated in pence per 30 g serving.
- UK availability — we only consider products that are reliably stocked in the UK at the time of last check.
- Last checked date — every product page records when we last verified the ingredient list.

Top picks
Our current shortlist is below. Each pick links through to a dedicated product page with the full ingredient breakdown.
- Example Whey Isolate (Unflavoured) — clean ingredient list, no added sweeteners. Best for people who want maximum control.
- Example Whey Isolate (Vanilla) — sweetened with sucralose, no polyols. A good option if unflavoured is unappealing.
What to avoid
Common ingredients that often appear in protein blends but that many low-FODMAP shoppers prefer to skip include:
- Inulin / chicory root extract — high FODMAP at typical doses.
- Sorbitol, mannitol, xylitol — polyol sweeteners.
- Whey concentrate — usually fine in small amounts but contains more lactose than isolate.
FAQs
Is any whey protein guaranteed low-FODMAP? No supplement can be "guaranteed" low-FODMAP for every individual. Tolerance varies. Use the ingredient flags here as a starting point and observe how your own body responds.
Why no medical or therapeutic claims? Because we are not qualified to make them, and because doing so would mislead readers. We focus on what is on the label.
