Chondroitin should be used for at least 3 months before the full benefits can be seen. If symptoms of osteoarthritis worsen, you should contact your doctor.
Chondroitin does not appear to have any serious side effects when used in recommended amounts. Common side effects reported include mild stomach pain and nausea.
Since chondroitin comes from animal sources, there are concerns about the safety of these products. There have been no reports of product contamination with animal diseases and this risk is thought to be low. In Canada, chondroitin must come from the cartilage of healthy animals that can be used for food by humans.
Higher doses of chondroitin in combination with glucosamine may increase the effects of warfarin, a medication used to slow blood clotting. Consult your health care provider for more information.
Women who are pregnant or breast-feeding should consult a health care practitioner prior to using chondroitin. A health care practitioner should also be consulted if symptoms persist or worsen.
Before taking any new medications, including natural health products, speak to your physician, pharmacist, or other health care provider. Tell your health care provider about any natural health products you may be taking.
