AdvaCare is a GMP manufacturer of Glucosamine + Chondroitin capsules.
Glucosamine and chondroitin are part of normal cartilage. Cartilage acts as a cushion between the bones in a joint. Glucosamine, also called chitosamine, is a natural substance that is found in the covering of shellfish. It is available in different forms, including glucosamine hydrochloride, N-acetyl-glucosamine (NAG), and glucosamine sulfate, which is a combination of glucosamine and mineral salt. Glucosamine is also available in synthetic forms. The body absorbs glucosamine well. Chondroitin can come from natural sources, such as shark or bovine cartilage, or it can be made in a lab. Chondroitin is also known as chondroitin sulfate, chondroitin sulfuric acid, and chonsurid.
Chondroitin sulfate is a combination of chondroitin and mineral salt. Glucosamine and chondroitin are available in tablet, capsule, powder, or liquid form and are often taken in combination with each other or in combination with other dietary supplements. Glucosamine may be taken separately as a dietary supplement for joints.
Many people take glucosamine and chondroitin, alone or together, for osteoarthritis. Some people believe this helps. But an analysis of studies looking at glucosamine or chondroitin for osteoarthritis in the hip or knee did not show that these supplements slow joint destruction or relieve pain.
It appears that glucosamine and chondroitin, alone or together, are safe and have few side effects. But they cost money and will not help you more than a placebo. Talk to your doctor if you are thinking about taking glucosamine and chondroitin. If you are allergic to shellfish, do not take glucosamine unless you have talked to your doctor. Some glucosamine is made from shellfish covering.
For advocates of glucosamine and/or chondroitin, this recent study is only the latest bit of bad news. But this is not likely to be the last word. There are different types and doses available and they are taken for a number of different conditions. There may be certain situations in which they are particularly helpful. Well need additional research to know what they are.
