The classic joint support combination at clinical doses from a trusted budget brand. Glucosamine and chondroitin have decades of research, though the evidence is more mixed than many realize — the large-scale GAIT trial produced nuanced results that both supporters and critics cite selectively.
NOW Foods Glucosamine & Chondroitin scores 74 for delivering the classic joint support combination at clinical doses with good value. The doses (1500mg glucosamine, 1200mg chondroitin per daily serving) match the major clinical trials exactly. Zero hype penalty — NOW Foods does not overclaim joint health miracles. The evidence score (72) reflects the mixed but non-negative evidence base: the GAIT trial showed benefit in moderate-to-severe OA pain, and the MOVES trial showed non-inferiority to a prescription NSAID. It is not a miracle but it is not useless either.
The glucosamine-chondroitin combination has extensive but mixed evidence. The landmark GAIT trial (Clegg et al., 2006, New England Journal of Medicine, n=1583) found that glucosamine + chondroitin was not significantly better than placebo for overall knee OA pain, BUT the subgroup with moderate-to-severe pain showed significant improvement (79.2% vs. 54.3% placebo response). Hochberg et al. (2016, MOVES trial, Annals of the Rheumatic Diseases) found glucosamine + chondroitin was non-inferior to celecoxib for knee OA pain over 6 months. Zhu et al. (2018) meta-analysis found glucosamine + chondroitin modestly reduced joint pain and improved function. The 1500mg glucosamine and 1200mg chondroitin in this product match the doses used in GAIT and other major trials.
| Ingredient | Dose | Verdict |
|---|---|---|
| Glucosamine Sulfate (from shellfish) | 1500mg | Optimal |
| Chondroitin Sulfate (bovine) | 1200mg | Optimal |
The GAIT trial primary endpoint was negative — glucosamine + chondroitin did not outperform placebo for mild knee OA pain overall. Requires taking 3 large capsules daily, which is a compliance burden. Results take 4-8 weeks to become noticeable. Derived from shellfish (glucosamine) — not suitable for shellfish allergies. Chondroitin is derived from bovine or shark cartilage, which raises sustainability and ethical concerns for some consumers. Not effective for all types of joint pain — evidence is primarily for knee osteoarthritis, not tendon or ligament issues.
