A daily prebiotic fiber supplement may help people with knee osteoarthritis manage pain and improve physical function, according to a new clinical trial. The study found that participants taking the supplement saw benefits over a six-week period, adding to interest in how gut health could influence joint symptoms.
Beyond lower knee pain, the results also pointed to broader physical changes. Researchers reported improvements in grip strength and pain sensitivity, suggesting the supplement’s effects may not be limited to the knee itself.
The findings raise the possibility of a gut-muscle-pain connection in osteoarthritis. Prebiotic fiber can affect the gut microbiome, and the new results hint that those changes may influence how the body experiences pain and maintains strength.
While the trial was short and more research is needed, the study suggests a simple daily supplement could become a practical option for some people with knee osteoarthritis. That may be especially notable because supplements are often easier to use consistently than more intensive treatment approaches.
