Overview

Arthritis refers to inflammation or swelling in a joint. The cause can be abnormal bone or joint development, instability of the surrounding ligaments and tendons, damage or injury to the joint, an infection or injury caused by the immune system. While anti-inflammatory medicines are popular treatments for arthritis, another approach involves protecting the cartilage in the joint and "nourishing" the joint.

Glucosamine and chondroitin belong to a class of drugs known as nutraceuticals. They are not drugs in the usual sense, but are prescribed for a druglike effect. Such drugs are NOT regulated by the FDA. Nutraceuticals are considered nutritional supplements, not drugs.

Cartilage and fluid within joints are crucial to normal joint function. With age, or after trauma, this cartilage may not be fully functional and fluid levels may diminish.

Glucosamine and chondroitin help provide the necessary nutrients for cartilage repair and function.

Glucosamine and chondroitin are available over the counter but should not be administered unless under the supervision and guidance of a veterinarian.
