Joint flexibility is vital for quality of life. Osteoarthritis is the most common form of joint disorders among older adults in the United States. Common symptoms of osteoarthritis and other joint disorders include inflammation, pain and stiffness. Research suggests that supplements such as glucosamine, chondroitin and methylsulfonylmethane, or MSM, promote joint health and prevent common complications.
Glucosamine
Glucosamine is a natural compound present in cartilage and joint fluid. Multiple studies from the National Institutes of Health report that glucosamine is an effective supplement in treating osteoarthritis. It strengthens joint cartilage and fluid in individuals suffering from pain, swelling and stiffness. Glucosamine has anti-inflammatory properties that improve overall joint function and reduce swelling in cases of mild to moderate osteoarthritis, according to the NIH. Glucosamine supplements are available as glucosamine sulfate in a capsule or tablet form. Studies report that 500 milligrams of glucosamine sulfate three times daily for 30 to 90 days is considered safe.
Chondroitin
Chondroitin is found naturally in the body and is a major component of joint cartilage. It cushions the joints and promotes cartilage health by absorbing fluid into the connective tissue, according to the University of Maryland Medical Center. Multiple scientific studies suggest that chondroitin promotes joint health and is an effective treatment for osteoarthritis. Medical center research found that chondroitin supplements relieved common symptoms associated with osteoarthritis, specifically in the knee and hip. Chondroitin is also effective in reducing swelling and inflammation in the joints and preventing stiffness. It also is combined with glucosamine supplements to support joint health, according to the medical center. No dietary sources of chondroitin exist, so it is commonly available as chondroitin sulfate in a capsule or tablet form.
MSM
MSM is a common supplement used for treating arthritis and other joint-related symptoms. A study by the Southwest College Research Institute reported that individuals attained significant improvement in physical activities and decreases in joint pain and impairment after taking 3 grams of MSM supplements twice a day.
