Systematic Review on Gluten Restriction in Multiple Sclerosis
A systematic review evaluated six studies on gluten diets in adults with MS. It found fatigue and quality of life improved most in trials without isolated gluten restriction. Evidence solely for gluten elimination was weaker, particularly from one randomized crossover trial showing no benefits for disability or immunological outcomes.

Why it matters
This review highlights inconsistencies in dietary approaches for MS and suggests that gluten restriction may not provide clear benefits for symptoms like fatigue and quality of life.
What this does not prove
The review included only six small, varied studies with low certainty in findings regarding fatigue, quality of life, and gluten elimination effects. No studies isolated gluten restriction as the only dietary change.

study designMEDLINE (via PubMed), Embase, Scopus, the Web of Science Core Collection, and the Cochrane Library were searched from 1 July from the inception of each database to 22 July 2026, supplemented by backward and forward citation searching.
subjectsEligible studies enrolled adults with MS and evaluated a gluten-free diet, a clearly defined gluten-restriction component, or habitual gluten exposure.
sample sizeOnly six studies were eligible, and they were small and clinically and methodologically heterogeneous; no randomised comparison isolated gluten restriction as the sole dietary change.
randomizedTwo parallel-group controlled trials were reported as randomised, one was a randomised crossover trial, two were non-randomised interventional studies, and one was observational.
controlledThe two studies reporting improved disability used adherence-based, non-randomised comparisons.
primary endpoint metBy contrast, the randomised crossover trial of marked wheat/gluten reduction found no disability benefit and had a negative primary immunological endpoint.
research categoriesOnly six studies were eligible, and they were small and clinically and methodologically heterogeneous; no randomised comparison isolated gluten restriction as the sole dietary change.
findingsEvidence specifically isolating gluten restriction was much weaker, and these results should not be read as showing that a gluten-free diet itself confers clinical benefit.
limitationsGRADE certainty was very low for all seven outcome domains, including fatigue and quality of life, and most of the evidence was indirect with respect to gluten elimination.
