Updated October 15, 2007

Glucosamine has been used to treat osteoarthritis and helps stimulates cartilage cells to synthesize glycosaminoglycans and proteoglycans. In studies oral glucosamine sulfate has had a beneficial effect on inflammation and mechanical arthritis.

Glucosamine Claims

  • Protect cartilage against damage from weight-bearing exercise
  • Slows cartilage breakdown
  • Stimulates cartilage growth
  • Cures arthritis

Research Shows

  • Glucosamine plays a role in maintenance and repair of cartilage
  • Glucosamine stimulates cartilage cells to synthesize cartilage building blocks
  • Glucosamine may have an anti-inflammatory action by interfering with cartilage breakdown

Tips and Cautions

  • Glucosamine is most effective for early arthritis when cartilage is still present
  • Glucosamine is less effective for severe arthritis
  • Glucosamine appears safe, however, more long-term research is needed to determine effectiveness
Glucosamine is a standard therapy in Europe, however, the U.S. suppliers are not regulated, so finding a trustworthy manufacturer can be difficult.
