Does glucosamine/chondroitin work to help repair torn cartilage?
This is another example of claims made on the Internet without much good science to back it up.
There have been some research studies that show improved function in those with arthritis when they consume a healthy diet. A variety of nutrients have been looked at, including various fats (Omega-3 and Omega-6), antioxidants, vitamins, and minerals.
One area that has been looked at is the role of Vitamin K in osteoarthritis. While it has been shown that those who have lower levels of Vitamin K are more prone to have osteoarthritis, there has not been evidence that supplements are beneficial.
Chondroitin and glucosamine have been very disappointing. While some small trials were promising, there has not been good quality large scale research to support that it is effective. The meta analysis of smaller trials has been generally negative, with the results not supporting the use of this supplement.
