Chondroitin Sulfate
How to Use It
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 after a few months. Before taking such high amounts, people should consult a doctor. For osteoarthritis, a typical level is 400 mg three times per day. Oral chondroitin sulfate is rapidly absorbed in humans when it is dissolved in water prior to ingestion. Approximately 12% of chondroitin sulfate taken by mouth becomes available to the joint tissues from the blood.1
Where to Find It
The only significant food source of chondroitin sulfate is animal cartilage.
Possible Deficiencies
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 arthritis.
