Our Verdict
Kirkland Signature Glucosamine is the Costco approach to joint health — maximum quantity at minimum price with USP Verification. The 1500mg glucosamine is at clinical dose, and the 1500mg MSM adds anti-inflammatory benefits. No chondroitin, but at this price you can add it separately and still pay less than Move Free.
