According to the Arthritis Foundation, one in three Americans - almost 66 million individuals - suffer from daily joint discomfort. Generally, arthritis refers to a disease of the joints, which can often result in joint pain, swelling, stiffening - or loss of joint function over time. The two most common types of arthritis are: (1) osteoarthritis, often called degenerative or "wear and tear" arthritis, usually appears after age 40 or 50 and develops slowly; (2) rheumatoid arthritis, considered an autoimmune disease, usually begins between the ages of 25 and 50.
Scientific reports show glucosamine, chondroitin sulfate, and Methylsulfonylmethane (MSM) supplements may reduce symptoms of osteoarthritis. Glucosamine and chondroitin are natural substances found in and around the cells of cartilage. Researchers believe these substances may help in the repair and maintenance of cartilage - that glucosamine inhibits inflammation and stimulates cartilage cell growth, while chondroitin provides cartilage with strength and resilience. MSM, a sulfur compound, is believed to help relieve pain and stiffness.
