Chondroitin sulfate. This is a combination of chondroitin and mineral salt. Chondroitin sulfuric acid. Chonsurid. Why It Is Used
Many people take glucosamine and chondroitin, alone or together, for osteoarthritis. Some people believe they help. But an analysis of studies looking at glucosamine or chondroitin for arthritis in the hip or knee did not show that these supplements slow joint damage or relieve pain.footnote 1
Risks
It appears that glucosamine and chondroitin, alone or together, are safe and have few side effects. But they cost money and will not help you more than a placebo
If you are allergic to shellfish, do not take glucosamine unless you have talked to your doctor. Some glucosamine is made from shellfish covering.
The Natural and Non-Prescription Health Products Directorate (NNHPD), within the Health Products and Food Branch of Health Canada, regulates natural health products in Canada. Natural health products, including glucosamine and chondroitin, must be reviewed and approved by the NNHPD before they can be sold in Canada.
