Omega-3 fatty acids are the most consistently evidence-backed supplement for inflammatory joint pain. Meta-analyses in rheumatoid arthritis find moderate benefit on pain and stiffness, with smaller benefit in osteoarthritis. Effect builds over 8-12 weeks. Higher doses (2-3 g combined EPA+DHA) outperform lower doses in joint-specific endpoints. Choose a third-party-tested product.^{[1, 2, 3]}

Curcumin in bioavailability-enhanced forms (Meriva phytosome, BCM-95, Theracurmin) has trial evidence comparable to NSAIDs (ibuprofen, diclofenac) for pain and function in mild-to-moderate knee osteoarthritis at 4-12 weeks. Crucial point: plain curcumin powder has near-zero bioavailability — the form matters enormously. Effect is mechanism-driven (NF-kB and COX-2 inhibition) and clinically meaningful in trial endpoints.^{[4, 5, 6]}

The classic joint-support pair. Trial evidence is mixed but generally positive for moderate-to-severe knee osteoarthritis, less clear for mild symptoms. Most positive trials used the SULFATE form of glucosamine (not hydrochloride) and combined it with chondroitin sulfate. Effect builds over 8-12 weeks. NIH GAIT trial found benefit specifically in moderate-to-severe knee pain subgroup.^{[7, 8, 9]}

UC-II is a small dose of undenatured type II collagen that works through an oral tolerance / immunomodulatory mechanism — different from the high-dose collagen peptides used for skin or hair. Small randomized trials in knee osteoarthritis show benefit on pain and function comparable to glucosamine + chondroitin. The low dose and clean side-effect profile make this an attractive complementary option, especially for knee-specific symptoms.^{[10, 11, 12]}

MSM is a sulfur-containing compound with anti-inflammatory and antioxidant activity. Small-to-medium trials show modest improvements in osteoarthritis pain and function. Effect size is smaller than curcumin or the glucosamine + chondroitin combination. Very wide safety margin. Treat as the most speculative item — useful as an add-on when other levers aren''t enough.^{[13, 14, 15]}
