Chondroitin

Origins
Chondroitin is a naturally occurring carbohydrate in humans and animals that is integral in the structure of cartilage, the connective tissue that cushions joints. As a supplement, it is sold as chondroitin sulfate, which is derived from cows, pigs, and marine life, mainly sharks.

Claims
Relief of joint symptoms from osteoarthritis and slows down osteoarthritis progression.

Evidence
Chondroitin sulfate is strongly recommended against in patients with knee and/or hip OA as are combination products that include glucosamine and chondroitin sulfate, but is conditionally recommended for patients with hand OA. A single trial suggested analgesic efficacy of chondroitin sulfate, without evidence of harm, in hand OA.

Safety
It’s safe to take, with only minor side effects reported.

Dose
A standard dose is 1000-1200mg daily in either one dose or two to three divided doses taken with food.

Where to find it
You can buy chondroitin sulfate supplements at pharmacies and supermarkets. It is usually sold in combination with glucosamine and has similar benefits taken alone or in combination.
