Why Glucosamine Sulfate for Bone & Joint
Glucosamine Sulfate plays a important role in bone & joint. Glucosamine is a naturally occurring amino sugar that serves as a building block for cartilage glycosaminoglycans and proteoglycans. Glucosamine sulfate has the strongest evidence base (GAIT trial, European GUIDE study).
What dose to look for
Clinical studies typically use 1000–1500 mg of glucosamine sulfate. Standard clinical dose is 1500 mg/day, often split into 3 × 500 mg doses. The GAIT trial and most European studies used 1500 mg/day glucosamine sulfate. GreenGrown is a common shellfish-free (corn-derived) branded form. Products below this range may not deliver meaningful results.
What the research says
Glucosamine Sulfate has moderate clinical evidence for bone & joint benefits. Large clinical trials including the GAIT trial support cartilage and joint health at 1500mg/day Learn more
