A supplement, like a vitamin, is something else you take in addition to your diet. Some studies suggest that certain supplements may help knee osteoarthritis.

These are:

  • Glucosamine seems to be involved in cartilage growth and repair.


  • Chondroitin sulfate helps make cartilage flexible.

Some people believe they reduce pain, help you move better, and reduce osteoarthritis symptoms.

Studies show that both glucosamine and chondroitin may help slow down the progress of knee osteoarthritis.

Even though glucosamine and chondroitin are “natural” remedies, they can cause side effects. These include bloating and softened stools. Glucosamine may also make diabetes worse. And, chondroitin may make some blood-thinning drugs work too well, keeping blood from clotting as it should.

Pregnant women should avoid both of these supplements.

Other supplements

A number of herbs, minerals, supplements, and alternative medicines have been promoted as remedies for osteoarthritis. Always talk with your doctor before using any alternative treatment. Like any medicine, some herbs, minerals, and other supplements can interact with drugs or foods, and produce side effects. Just because something is natural does not mean that it is safe.
