While it is a prescription or over-the-counter drug in 22 countries, chondroitin is regulated in the U.S. as a dietary supplement [36] by the Food and Drug Administration. In Europe, chondroitin sulfate formulations are approved as drugs with evidenced efficacy and safety demonstrated by clinical trials in people with osteoarthritis. [37]
Chondroitin sulfate; Dermatan sulfate; Chondroitin as a supplement is now commonly used (often in combination with glucosamine) in treating the joint disease of osteoarthritis. [2] In contrast to the symptomatic treatments, chondroitin can modify the progression of a disease process in the patient which it can be used as an alternative medicine ...
Glucosamine is often sold in combination with other supplements such as chondroitin sulfate and methylsulfonylmethane. [citation needed] Glucosamine, along with commonly used chondroitin, is not routinely prescribed to treat people who have symptomatic osteoarthritis of the knee, as there is insufficient evidence that this treatment is helpful ...
The two main proteoglycans that are used in this process are heparan sulfate proteoglycans (HSPGs) and chondroitin sulfate proteoglycans (CSPGs) which are present at high levels in the chondrocyte extracellular matrix and are crucial in regulating chondrocyte maturation. When the GAG chain functions properly, it controls the maturation speed of ...
Emergen-C is an effervescent, powdered drink mix vitamin supplement manufactured by Alacer Corp. The Emergen-C product line was introduced in 1978. [1] Alacer was established as a private company in 1972, focusing on vitamin supplements containing vitamin C.
Aggrecan (ACAN), also known as cartilage-specific proteoglycan core protein (CSPCP) or chondroitin sulfate proteoglycan 1, is a protein that in humans is encoded by the ACAN gene. [5] This gene is a member of the lectican ( chondroitin sulfate proteoglycan ) family.
The study also found chondroitin sulfate to have no significant effect in reducing joint swelling, effusion, or both. These results indicate that glucosamine and chondroitin do not effectively relieve pain in the overall group of osteoarthritis patients, though it may be an effective treatment for those suffering from moderate-to-severe pain. [57]
Decorin is a protein that in humans is encoded by the DCN gene.. Decorin is a proteoglycan that is on average 90 - 140 kilodaltons (kDa) in molecular weight. It belongs to the small leucine-rich proteoglycan (SLRP) family and consists of a protein core containing leucine repeats with a glycosaminoglycan (GAG) chain consisting of either chondroitin sulfate (CS) or dermatan sulfate (DS).
