Why this tier: The largest single trial (GAIT, NIH-funded, n>1,500) used glucosamine HCl and found NO significant overall benefit vs placebo -- weaker/more mixed evidence than sulfate for whole-population efficacy, though one Chinese multi-center RCT found HCl and sulfate equally effective head-to-head; the gap is debated, not settled.
