Fiber Supplement for Knee Osteoarthritis Pain: What the Inulin Trial Found

  • In the UK INSPIRE trial (Nutrients, February 2026), 117 adults with knee osteoarthritis took 20 g a day of inulin, a prebiotic fiber found in chicory root, did an app-based exercise program, did both, or took a placebo powder for 6 weeks.
  • Compared with placebo, knee pain fell by 1.11 points on a 0–10 scale with inulin, 1.55 with exercise and 1.67 with both. Inulin also improved grip strength by about 4.6 kg (10 lb), while exercise improved standing and walking tests.
  • The trial was small and short, randomization was changed partway through, and the inulin pain result was borderline (95% CI −2.18 to −0.04). A blinded US trial at Yale is listed with an estimated start of November 2026.

How we work

Fitness information you can check

The Fitness Falcon is an independent publication. This is how we research, date and correct what we publish.

Editorial policy Who we are Report a correction

  • Built on reliable sources

    We research articles from public health agencies, peer-reviewed studies and official product specs, and our current guides link the sources they use.

  • Dated and kept current

    Time-sensitive details such as prices, features and guidelines show when we checked them, and we update articles when they change.

  • Clear about limits

    Reviews say when they are research-based rather than hands-on. Health content is general information, not medical advice.
