Ten years on glucosamine? Here’s the NIH 1,583-person trial and the BMJ meta-analysis.

  1. 1GAIT (NEJM 2006): pain response placebo 60%, glucosamine 64%, chondroitin 65%, both 67% — none significant
  2. 2BMJ 2010 (3,803 people): pain improved 0.3–0.5 cm on a 10-cm scale, below the 0.9 cm that matters clinically
  3. 3Joint-space change on X-ray same as placebo — no “cartilage repair”
  4. 4Industry-funded trials showed 0.5 cm more effect than independent ones
  5. 5ACR 2019, OARSI 2019 and NICE 2022 all recommend against
  6. 6What works: exercise therapy and weight loss (each kg lost cuts knee load by about 4 kg)

Kidney patients: some products carry potassium or sodium; possible interaction with warfarin. Fairly safe — just don’t skip the exercise.
