Scientists Say This Surprising Supplement May Relieve Knee Arthritis Pain

Key Points:

• A recent six-week clinical trial involving 117 adults with knee osteoarthritis found that taking a daily prebiotic supplement (inulin) improved grip strength and reduced pain, suggesting potential benefits beyond digestive health.
• Experts explain that prebiotic supplements may help relieve arthritis pain by supporting gut health, which influences inflammation and pain perception; inulin specifically may regulate pain and reduce cartilage breakdown via enhanced GLP-1 secretion.
• Prebiotics also support digestive health, immune function, and metabolic health, but may cause side effects like gas or bloating, and are not recommended without medical advice for people with certain gastrointestinal conditions or those on low-FODMAP diets.
• Increasing prebiotic intake through foods such as onions, garlic, asparagus, and bananas is recommended before considering supplements, which should be discussed with a healthcare provider, especially for those with digestive issues or other medical conditions.
• While promising, the study’s small size and incomplete understanding of mechanisms mean larger, longer-term research is needed; prebiotics are not a replacement for standard arthritis treatments but may complement other therapies.
