Simple Fiber Supplement Cuts Knee Arthritis Pain in Just 6 Weeks, Study Finds

University of Nottingham researchers found that six weeks of inulin supplementation reduced knee osteoarthritis pain.

The prebiotic fiber also improved grip strength and pain sensitivity, hinting at broader benefits beyond joint pain.

In the INSPIRE trial, inulin had far better adherence and much lower dropout than a digital exercise program.

The findings suggest a low-cost, low-risk dietary approach may help manage chronic osteoarthritis pain and may involve the gut-muscle-pain axis.
