- University of Nottingham researchers led a six-week clinical trial showing that inulin, a prebiotic fiber, reduced knee osteoarthritis pain and improved physical function in participants.
- Inulin supplementation increased levels of butyrate and GLP-1, compounds tied to gut health, inflammation regulation, and pain modulation, suggesting a biological mechanism for symptom improvement.
- Participants taking inulin alone had a 3.6% dropout rate, significantly lower than the 21% dropout rate in the digital physical therapy group, indicating higher adherence to the supplement.
- Grip strength improved in the inulin group—a finding not seen with physical therapy—suggesting the supplement may influence muscle function beyond joint-specific effects.
- GLP-1 levels were positively associated with grip strength, pointing to a potential gut-muscle-pain axis that could inform broader research on aging and physical resilience.
- Arthritis UK supports further exploration of diet and physiotherapy as complementary approaches, citing the high burden of daily pain reported by six in ten people with arthritis.
Why it matters: People with knee osteoarthritis may gain a low-barrier, well-tolerated option for pain relief and functional improvement, especially those unable to adhere to physical therapy. The 17.4 percentage-point difference in dropout rates between treatments highlights a practical advantage for public health interventions aiming to improve long-term symptom management.
