Frequently Asked Questions


Our laboratory cartilage cell culture research has demonstrated that the two main ingredients in Cosamin® DS, glucosamine and chondroitin sulfate, work in synergy to stimulate the production of cartilage matrix components and inhibit enzymes that break down cartilage.*

Take 3 capsules or caplets daily until desired comfort level is reached. Then gradually reduce number of capsules taken daily to maintain comfort level. Capsules may be taken all at once or divided with meals throughout the day.*

Early action is always the best advice. If you notice changes in flexibility or joint function it is best to see your doctor. Your doctor may discuss weight control and/or exercise. For those who exercise daily or strenuously, Cosamin® DS may be taken to help support joint health.*



The ingredients in Cosamin® ASU work at the cellular level to support cartilage protection and joint comfort. Laboratory studies show that the combination of ingredients in Cosamin® ASU decreases levels of markers associated with cartilage breakdown and joint discomfort.*

Take 3 capsules daily until desired comfort is reached. May reduce number of capsules taken daily to maintain comfort level. Capsules may be taken all at once or divided with meals.*

Additional Information

Joints are the junction between two or more bones. The ends of the bones are covered with cartilage which serves as a smooth, resilient cushion that allows the joint to move freely. Joints also have a synovial tissue lining that encloses them and secretes a lubricating fluid that also supplies hydration and nourishment to cartilage. The stability of the joint is supported by ligaments that connect bones to bones; and tendons that connect the ends of muscles to bone. Cartilage in the joint is produced and maintained by its own specialized cells. When you do even the simplest of everyday activities, there is tremendous pressure on your joints. The protective cartilage cushion and joint fluid work together like a shock absorber to allow for proper joint flexibility.

There are many factors that lead to cartilage breakdown such as age, excess weight, inactivity or over activity, injury, genetics, or cartilage lacking a direct blood supply.

Your doctor understands that there are differences between glucosamine/chondroitin brands and that is why Cosamin® was recommended to you. Cosamin® is proven to improve joint comfort by more published research than any leading joint supplement. Cosamin® is tested for purity, quality and meeting label claim by industry respected, independent testing laboratories as well as by Nutramax Laboratories’ own Quality Control and Assurance laboratories.

No, we use a non-shellfish derived glucosamine in Cosamin® DS, Cosamin® ASU, Cosamin® Sport, and Cosamin® Muscle & Joint.
