Chondroitin is associated with the treatment of osteoarthritis, however a review of all research including more recent, large scale high quality trials does not give conclusive evidence for chondroitin reducing symptoms 2. A 6 month study of glucosamine and chondroitin efficacy in 2006 showed that a small subset of those with moderate to severe joint pain sample had less pain and joint swelling when they took chondroitin with glucosamine rather than just glucosamine or a placebo, although positive results need further research3.
Chondroitin is widely considered to be one of the safest treatments for osteoarthritis4 and is considered to be safe for long term use4. Chondroitin is usually extracted from shark cartilage. Chondroitin is not proven to be safe in pregnancy and lactation, can interact with several medications in particular warfarin – always check with your GP. Those with increased risk of or diagnosed prostate cancer and asthmatics should take chondroitin with care5.
