Isolated Supplements and Osteoarthritis


According to the American Academy of Orthopedic Surgeons, "[o]steoarthritis is the most common form of knee arthritis," with approximately 9 million Americans suffering from this condition (as of 2005). Moreover, osteoarthritis is a painful degenerative disease of the joint cartilage that causes disability for millions of people.

Consequently, the medical profession has long sought to find either a cure or a reliable method of reliving the pain of this condition, and they have found it-with isolated supplements. Or have they?

Glucosamine and Chondroitin Sulfate

Glucosamine or chondroitin sulfate (alone or in combination) are two types of isolated supplements that have received much media attention for their purported ability to slow the progression of osteoarthritis as well as relieve the sometimes excruciating pain of this condition.

Since glucosamine is a component of cartilage, it would make sense that supplementation with glucosamine might improve the symptoms of knee osteoarthritis. Indeed, previous studies have indicated that glucosamine supplementation may well reduce the inflammation and the pain of this condition-especially when combined with chondroitin sulfate.

Chondroitin sulfate is an essential building block for the structure of the joint that is purported to slow the progression of osteoarthritis and to have some (limited) beneficial effects on the pain of this condition. In combination, these two isolated supplements-glucosamine and chondroitin sulfate-are considered to be a miraculous mixture for the successful treatment of this condition.

The Science

Although their have been many conflicting studies about the efficacy of glucosamine and chondroitin sulfate in the treatment of osteoarthritis, the results of a 2008 study are particularly compelling.

This Glucosamine-chondroitin Arthritis Intervention Trial (GAIT) tested the effects of these two isolated supplements-alone and in combination-on patients who suffered from knee osteoarthritis. According to Medpage today, "[p]atients in GAIT were randomized to 1,500 mg of glucosamine hydrochloride, 1,200 mg of chondroitin sulfate, both glucosamine and chondroitin, 200 mg of celecoxib (Celebrex), or placebo for up to two years."

Are Isolated Supplements Enough?

The results of GAIT showed the isolated supplements of glucosamine and chondroitin did not significantly slow the progression of knee osteoarthritis (as indicated by x-rays taken throughout the study). Moreover, these two isolated supplements, when combined, were less effective than placebos at slowing the progression of osteoarthritis.

Dr. Allen D. Sawitzke and colleagues at the University of Utah, who conducted the study, theorized that chondroitin might hinder the proper absorption of glucosamine, which could explain why the combination of these supplements were ineffective. But, Sawitzke stressed, none of their tests indicated a statistically significant improvement in those with severe osteoarthritis for either one of these isolated supplements. There were some beneficial effects seen in those with moderate osteoarthritis, however, (The results of this study were published in the October 2008 issue of Arthritis and Rheumatism).

It should be noted, however, that GAIT only studied the effects of glucosamine and chondroitin on the progression of osteoarthritis-not on their possible effects on the pain of this condition.

What is the Solution?

Glucosamine and chondroitin are not the only two isolated supplements that have been promoted as "natural cures" for the inflammation, pain, and crippling progression of osteoarthritis. Indeed, supplementation with S-adenosylmethionine (SAMe) or Niacinamide (a form of B3) have also been shown, in studies, to improve osteoarthritis symptoms.

But the best way to treat osteoarthritis, say experts, is to combine such isolated supplements with a number of medical and holistic treatment options.

Medical and Holistic Treatment Options of Osteoarthritis

There are several medical and holistic treatment options that have shown varying degrees of effectiveness in the treatment of osteoarthritis. Here is a list of just a few of them.

Drugs. There are many prescription and non-prescription drugs-such as acetaminophen, NSAIDS (nonsteroidal, anti-inflammatory drugs), and analgesics-that have proven to bring some relief from the pain of osteoarthritis.

Exercise. Regular physical exercise has proven to ease the pain, and aid joint flexibility, in those with osteoarthritis. (Exercise lubricates the joints, making movement less painful).

Knee support. Methods of stabilizing the knee-such as knee wraps and knee braces-have proven to reduce the pain of osteoarthritis.

Weight Reduction. Obesity is not only a risk factor for developing osteoarthritis, but it can worsen the pain and joint stiffness of this condition. Losing weight, therefore, is a valid treatment option for this condition.

Tropical creams. There are a number of tropical creams on the market that have shown to reduce the pain of arthritic joints. These are generally used in combination with other treatment options-such as isolated supplements and exercise-to provide relief from osteoarthritis.

Acupuncture. This ancient therapy-which uses needles to open healing energy pathways within the body-has been proven alleviate many types of pain, including that of osteoarthritis.

Lifestyle modifications. The pain of osteoporosis can frequently be relieved by making a few simple lifestyle modifications. For instance, change exercise from from running (which puts stress on the joints) to walking. Avoid frequent climbing of stairs. Participate in water aerobics, or other aqua exercises, which cushions the joints while giving the body a good workout.

Surgery. There are many surgical options used to treat osteoarthritis. Some of these surgeries allow the doctor to clean out the debris around the knee joint. Other surgeries involve a complete or partial replacement of the kneecap. These surgeries are typically used when all other methods have failed.

Today, there are many treatment options for osteoarthritis that go beyond isolated supplements. Although each of these methods have shown varying rates of success, a combination of them could well relieve the pain (and even the progression) of this, one of the most common types of arthritis.
