A compound derived from glucose that is a component of cartilage and is often used as a dietary supplement to support joint health.
From glucose + amine (a chemical group containing nitrogen), coined in 19th-century chemistry. The term describes a glucose molecule where an amino group replaces a hydroxyl group.
Glucosamine is one of nature's building blocks for cartilage, and many athletes and older adults take it hoping to rebuild worn-out joints—the science is mixed, but some studies suggest it does help with osteoarthritis pain.
