Glucosamine for Osteoarthritis: Lack of Efficacy

Evidence Against Glucosamine Use

• The American College of Rheumatology recommends against the use of glucosamine for osteoarthritis treatment, as multiple high-quality clinical guidelines strongly recommend against its use 1, 2, 3
• The 2019 American College of Rheumatology/Arthritis Foundation guidelines state that data with the lowest risk of bias fail to show any important benefits of glucosamine over placebo 4, 5
• The British Medical Journal (NICE) guidelines explicitly state that "the use of glucosamine and chondroitin products is not recommended" 3, 7, 8

Recommended Alternatives for Osteoarthritis Management

• The British Medical Journal recommends core treatments that should be recommended instead, including physical activity and exercise, weight loss interventions for overweight or obese patients, acetaminophen as first-line pharmacologic treatment for mild to moderate pain, topical NSAIDs for localized joint pain, and topical capsaicin as an alternative topical agent 3, 7, 8, 9

Clinical Approach

• When patients inquire about glucosamine, the American College of Rheumatology recommends explaining that the highest quality evidence shows no benefit over placebo for pain relief or disease modification 1, 2
• The British Medical Journal recommends redirecting patients toward evidence-based treatments with proven efficacy for osteoarthritis 3, 7, 9
