Supplements for Osteoarthritis – Evaluating the Evidence
A new review evaluates the evidence for supplements to treat osteoarthris
New Evidence for Chondroitin
Several previous studies showed chondroitin was ineffective for knee osteoarthritis, but a new study says it is as effective as celecoxib. There are reasons to be skeptical.
Glucosamine Update
Osteoarthritis, the “wear-and-tear” type of arthritis, affects a great many of us as we grow older. Knee pain is a common symptom. The diet supplements glucosamine and chondroitin have been proposed as a more “natural” treatment than pharmaceuticals, and they are components of a number of proprietary “joint health” formulations like Osteo Bi-Flex.

They are used widely for osteoarthritis, especially of the knee, and have been better studied than most other diet supplements. But do they really work? The journal of my medical specialty, American Family Physician, recently published an article about the use of dietary supplements in osteoarthritis. They gave...
