Chondroitin sulfate consists of repeating chains of molecules
called glycosaminoglycans (GAGs). Chondroitin sulfate is a major
constituent of cartilage, providing structure, holding water and
nutrients, and allowing other molecules to move through
cartilage—an important property, as there is no blood supply to
cartilage. Where is it found? The only significant food source
of chondroitin sulfate is animal cartilage. Chondroitin sulfate
has been used in connection with the following conditions (refer
to the individual health concern for complete information): Who
is likely to be deficient? Because the body makes chondroitin,
the possibility of a dietary deficiency remains uncertain.
Nevertheless, chondroitin sulfate may be reduced in joint
cartilage affected by osteoarthritis and possibly other forms of
How much is usually taken? For atherosclerosis, researchers have
sometimes started therapy using very high amounts, such as 5
grams twice per day with meals, lowering the amount to 500 mg
three times per day aft
