Made up of repeating chains of glycosaminoglycans (GAGs), chondroitin sulfate is a major component of cartilage. Because cartilage does not have a blood supply, chondroitin sulfate is especially important in that it makes it possible for various other molecules to move throughout the cartilage. It also works to hold in nutrients and water, and provides an element of structure.
In diseases, such as osteoarthritis, where the joints begin to deteriorate, cartilage is lost and subsequently chondroitin sulfate levels diminish as well. In a number of clinical studies use of supplemental chondroitin sulfate has proved beneficial in treating the symptoms and potentially slowing down or reversing the effects of osteoarthritis.
In addition to cartilage, chondroitin and other such compounds are found in the bladder and in the lining of blood vessels. They help prevent excessive blood clotting (however it is still unknown as to weather or not chondroitin supplements positively affect blood clotting properties) and prevent abnormal movement of urine, blood, or other components across the bladder or blood vessel wall. Chondroitin sulfate may also be useful in lowering high levels of blood cholesterol. Past research has linked the prevention of atherosclerosis in both humans and animals to chondroitin sulfate, and suggests that chondroitin may also prevent heart attacks in those already diagnosed with atherosclerosis.
Chondroitin is related to glucosamine and contains high levels of sulfur.

It has been asked by millions of people “If you eat a healthy diet, do you need to take vitamins?” Not very long ago, the common answer from most experts and professionals would have been an emphatic "no". However, today there's quite a bit of evidence that taking a daily multivitamin makes good sense for most adults.

Given the popularity and availability of “high potency” amino acids, antioxidants, enzymes and herbs, it might seem like dietary supplements could replace food as a source of the nutrients the body requires. However, this is not the case.
