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. The dietary supplements chondroitin and glucosamine, separately or in combination, have been widely used to treat the pain of osteoarthritis of the knee.… read more "New Evidence for Chondroitin"
Glucosamine and chondroitin are widely used for osteoarthritis pain. My daughter even gives them to her elderly horse. Their popularity is puzzling, since the evidence from scientific studies indicates that they don’t work. Wikipedia has a useful survey of the history, studies, criticisms, and systematic reviews (https://en.wikipedia.org/wiki/Clinical_trials_on_glucosamine_and_chondroitin). It includes a… read more "Glucosamine and Chondroitin: Do They Really Work?"

Glucosamine and chondroitin, used separately or together, are among the more popular diet supplements. 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… read more "Does Glucosamine Really Work?"
In case you hadn’t noticed, snake oil is alive and thriving under the shield of alternative medicine. As the Baby Boomers approach retirement age and develop health problems, we can expect an even greater boom of quackery, pseudoscience, and misinformation. Even the most critically thinking scientist may think less critically… read more "Keeping an Eye on Alternative Medicine"
