Glucosamine is composed of glucose (a sugar) and glutamine (an amino acid). It is used by chondrocytes to form glycosaminoglycans (GSG) and proteoglycans (PG). Both of these constituents attract and bind water into cartilage, increasing resiliency.

MSM contains a lot of sulfur – 34% by weight. Sulfur is significant in joint health. MSM is thought to deliver sulfur to the body in a useable way. Sulfur helps maintain the structure of connective tissue by forming cross-linkages through disulfide bonds, for example, sulfur strengthens the tissues that make up the joint.

Research indicates that glucosamine may help your body repair damaged or eroded cartilage. A number of studies have been conducted on glucosamine sulfate and glucosamine hydrochloride, with a majority of positive results. Glucosamine sulfate is considered the more effective of the two.
One study from the University of Liege in Liege, Belgium studied the effects of glucosamine sulfate on 212 patients with knee osteoarthritis. Participants were given either 1,500 mg glucosamine or a placebo once daily for three years. The study compared joint-space width at enrollment, one year, and at the study’s conclusion. The 106 patients on placebo had a progressive joint-space narrowing, while participants taking glucosamine experienced no significant joint-space loss, indicating glucosamine may beneficially modify cartilage structure.
A study published in the journal Osteoarthritis and Cartilage in 1998 investigated the in vitro effects of glucosamine sulfate on proteoglycan and collagen making by chondrocytes taken from osteoarthritic articular cartilage. The results demonstrated “a statistically significant stimulation of PG production by chondrocytes from human osteoarthritic cartilage cultured for up to 12 days in 3-dimensional cultures.”
Another study from Italy enrolled eighty inpatients with established OA. They were given either 1,500 mg of glucosamine sulfate or placebo daily for 30 days. The patients given with glucosamine sulfate experienced a reduction in symptoms almost twice as large and twice as fast as those receiving placebo. Researchers also used electron microscopy of patient’s articular cartilage to support this hypothesis. Patients who received glucosamine sulfate showed a picture more similar to healthy cartilage. The researchers concluded that glucosamine sulfate tends to rebuild damaged articular cartilage and restore articular function.

Chondroitin is classified as a glycosaminoglycan. It bonds with collagen to form the basis of connective tissue. Chondroitin helps attract fluid into proteoglycans, thereby bringing nutrients into cartilage and providing shock absorption.

Glucosamine helps manufacture and maintain cartilage and chondroitin keeps cartilage from becoming malnourished. Chondroitin works synergistically with glucosamine, and these two nutrients form the basis of most joint health supplements on the market today.

Yes. A 6-month randomized, multi-center, double blind, double-dummy study published in 1996 compared the effectiveness of chondroitin versus a popular non-steroidal anti-inflammatory drug (NSAID) in patients with knee osteoarthritis (OA). One hundred and forty-six patients with knee OA were recruited and separated into two groups; an NSAID group and a chondroitin sulfate (CS) group. The NSAID group received the NSAID and a placebo for the first month, then placebo alone for months 2-3. The CS group received the NSAID and CS for the first month, and then CS alone for months 2-3. Both groups were then given 1200 mg of CS for months 4-6. “Patients treated with the NSAID showed prompt and plain reduction of clinical symptoms, which, however, reappeared after the end of treatment; in the CS group, the therapeutic response appeared later in time but lasted for up to 3 months after the end of treatment. CS seems to have slow but gradually increasing clinical activity in OA; these benefits last for a long period after the end of treatment.”

MSM, methylsulfonylmethane (METH-?l-sul-FON-il-METH-ane) provides sulfur, a vital building block of joints, cartilage, skin, hair and nails, and methyl groups, which support many vital biochemical processes in the body, including energy production. MSM is a naturally-occurring nutrient found in small amounts of many foods. All commercially available MSM is manufactured by reacting dimethyl sulfoxide with hydrogen peroxide. The raw materials used to manufacture MSM have many sources, including plants or other organically-based material. The source of these raw materials has no relationship to the end product of MSM.

 MSM has many health benefits. Some of them are:

• Improves joint flexibility.
• MSM helps repair cartilage.
• MSM helps increase energy.
• MSM helps reduce inflammation due to injury or inflammatory diseases such as arthritis.
• MSM has been proven to help in the reduction and even the total elimination of allergies.
