As usual, the New York Times and the rest of the media got the story wrong.(4) Rather than being ineffective, as the media concluded about glucosamine and chondroitin for knee pain, the NIH GAIT study actually showed the opposite.(3)
Glucosamine and Chondroitin are nutritional supplements that have no adverse side effects. Annual glucosamine sales have increased considerably over the last 10 years (see chart below). Sales have increased from 1 million dollars a year in 1995 to 700 million dollars a year in 2005.
Glucosamine More Effective than Celebrex
Contrary to the New York Times report, the NIH Gait study actually showed that in patients with moderate-to-severe knee-pain, the combination of the two supplements (glucosamine and chondroitin) was more effective than both Celebrex and a placebo. The glucosamine-chondroitin combination significantly reduced pain in 79 percent of those who received it. Celebrex significantly reduced pain in 69 percent of the recipients and the placebo in 54 percent.(1)(2)(15)
Financial Ties to the Drug Industry Lead to Biased Results
How is it possible for the New York Times to get the wrong story? Could it be possible that the authors of the New England Journal reporting the GAIT findings were biased in favor of the drug Celebrex, and against the supplements?(15)
Jay Gordon MD raises this question in his article, “Did You Understand the Arthritis Study? I Did.”(16) Dr Gordon points out that the authors received financial rewards from the competitive companies making the arthritis drug Celebrex. This conflict of interests biased the authors to spin the results in favor of the drug and against the glusosamine.
Here’s a complete list of the disclosure of financial ties the study’s authors have to the drug industry:
Drs. Bingham, Brandt, Clegg, Hooper, and Schnitzer report having received consulting fees or having served on advisory boards for McNeil Consumer and Specialty Pharmaceuticals.
Drs. Brandt, Moskowitz, Schnitzer, and Schumacher report having received consulting fees or having served on advisory boards for Pfizer.
Dr. Brandt reports having equity interests in Pfizer.
Drs. Moskowitz and Weisman report having received lecture fees from Pfizer; Dr. Brandt, lecture fees from McNeil Consumer and Specialty Pharmaceuticals;
Drs. Bingham, Clegg, Hooper, Jackson, Molitor, Sawitzke, and Schnitzer, grant support from Pfizer; and Dr. Bingham, grant support from McNeil Consumer and Specialty Pharmaceuticals.
Dr. Brandt reports having received royalties from books related to osteoarthritis.
Dr. Moskowitz reports having served as an expert consultant for Pfizer.
None of the authors received any money from makers of glucosamine or chondroitin.
What is Glucosamine ?
Glucosamine and chondroitin sulfate are substances found naturally in the body. Glucosamine is a form of amino sugar that is used for cartilage formation and repair. Chondroitin sulfate is part of a large protein molecule (proteoglycan) that gives cartilage elasticity. Both glucosamine and chondroitin sulfate are sold as dietary or nutritional supplements available at the health food store without the need for a prescription. Glucosamine is a less expensive and safer alternative to NSAID pain pills which are commonly prescribed for arthritis pain.(14)
Safety of Glucosamine/ Chondroitin Compared to the Safety of NSAIDS, Adverse Side Effects of Celebrex
The media stories on the GAIT Study also fail to mention the fact that Glucosamine and Chondroitin have no adverse side effects, while Celebrex causes gastric bleeding, ulceration and death. This is an important distinction. Celebrex is a NSAID pain pill. NSAID drugs are similar to aspirin, ibuprofen, and naproxen. It has been estimated conservatively that 16,500 NSAID-related deaths occur among patients with rheumatoid arthritis or osteoarthritis every year in the United States.
Deaths Reported from Celebrex
On 4/20/99, The Wall Street Journal reported that celecoxib (Celebrex) has been linked to 10 deaths and 11 cases of gastrointestinal hemorrhages. Five of the 10 who died suffered from gastrointestinal bleeding or ulcers.(5)(6)
On December 17, 2004 Pfizer publicly announced that patients who are taking Celebrex may have an elevated risk of suffering heart attack and stroke. The National Cancer Institute designed a study to research the effects of Celebrex on cancer. This Pfizer-sponsored study was suspended after preliminary evidence showed that clinical trial patients who were taking 400 to 800 milligrams of Celebrex were two and
a half times more likely to suffer from heart attack or cardiovascular stroke than patients in the control group.
Celebrex No Safer than the Older NSAIDS
An editorial published in the British Medical Journal reports that COX-2 selective painkillers (Like Celebrex and Vioxx) are no safer on your stomach than traditional painkillers.(7) When COX-2 drugs like Celebrex were introduced to the market, their makers claimed these drugs were as effective and much safer than the older NSAID drugs. In other words, they were easier on the stomach. Older NSAIDs, such as Aleve and Naproxen, are known to cause adverse gastrointestinal side effects like ulcers and bleeding. The authors of this BMJ editoral say that the original studies were flawed and that the new COX-2 drugs like Celebrex and Vioxx are just as dangerous as older NSAID drugs.(7)(8)
Annual Death Rate for NSAIDS
The following are the references for the estimated annual death rate from NSAIDs (Nonsteroidal anti-inflammatory drugs including aspirin, ibuprofen, naproxen, diclofenac, ketoprofen, and tiaprofenic acid.) How many of these deaths are due to Celebrex vs. the others NSAIDs? Compare this number of deaths to ZERO deaths from glucosamine and chondroitin.
Each year, there are an estimated 103,000 hospitalizations and 16,500 deaths in the United States attributed to complications from NSAID-associated gastric ulcers.(9)(10)
Another medical report says there are 7,600 deaths and 76,000 hospitalizations in the United States annually form adverse side effects from NSAID drugs, mostly gastric bleeding.
According to November 2004 Congressional testimony by Dr. David Graham, associate director for science and medicine in the FDA’s Office of Drug Safety, there were 160,000 heart attacks and as many as 55,000 patients may have died as a result of taking Vioxx. (13)

Glucosamine and Chondroitin is a SAFER ALTERNATIVE to NSAIDS
The entire point of the above is to demonstrate the safety profile of glucosamine and chondroitin as compared to the dangers of NSAIDS. Glucosamine and chondroitin are nutritional supplements available without a prescription at the vitamin store, most drugstores, and grocery stores.
