Fiber Supplement Reduces Knee Pain and Improves Strength

Topic: Health

A new study found that taking a daily fiber supplement reduced knee pain and improved strength in people with knee osteoarthritis. The supplement, called inulin, is a natural dietary fiber found in chicory root and other vegetables.

Researchers at the University of Nottingham led a clinical trial to test the effects of inulin on people with knee osteoarthritis. They divided 117 adults into four groups: one group took inulin alone, another group received digital physiotherapy-supported exercise (PSE) alone, a third group got both treatments together, and a fourth group received a placebo.

The results showed that taking inulin daily reduced pain among participants with knee osteoarthritis. In fact, the group that took inulin had far fewer dropouts than those assigned to PSE. Only 3.6% of participants taking the supplement left the study, compared with 21% of those in the physiotherapy group.

But what's even more interesting is that the inulin group experienced improved grip strength and lower pain sensitivity. This suggests a possible connection between gut health and muscle function. The researchers think this could be an important area for further study.

Why It Matters

This discovery matters because knee osteoarthritis affects hundreds of millions of people worldwide, causing chronic pain and disability. A simple dietary change like taking a fiber supplement could provide a new way to manage this condition, especially for older adults who may struggle with exercise programs.
