Osteoarthritis is a form of arthritis that damages joints and cartilage. Symptoms include joint pain, stiffness and inflammation. Your body requires the essential mineral selenium for proper functioning and growth. In some research studies, selenium has been found to alleviate symptoms of osteoarthritis. However, larger studies are needed to fully confirm its benefits. Always consult your health care provider before starting selenium or any other supplements for managing your condition.
Research
According to the results of a study published in the January 2011 issue of "Osteoarthritis and Cartilage," selenium has been found to be effective for managing osteoarthritis symptoms and possibly preventing the progression of the disease. The research team explained the possible mechanism by which selenium helps manage osteoarthritis: It was found to neutralize the effects of interleukin-1 beta, a substance that promotes inflammation.
Individuals with arthritis appear to have reduced selenium levels in the blood and low selenium dietary intake, according to National Institutes of Health. The NIH indicates that selenium has antioxidant qualities that can limit joint damage caused by free radicals.
Dosage
Selenium is available as an over-the-counter supplement in capsules and tablets. The recommended dosage is 55 micrograms of selenium per day, according to National Institutes of Health. Your doctor may recommend a higher dosage if your symptoms are severe or your blood test shows selenium deficiency. Taking to much selenium may cause diarrhea, baldness, nausea and vomiting, skin itch, irritability, bad breath, fragile finger nails and fatigue.
Warnings
Do not use selenium supplements if you have kidney problems or digestive conditions. Do not use high doses of selenium if you are pregnant, as studies on animals showed possible harmful effects on the baby, according to Drugs.com. In these cases, consider increasing the intake of this mineral from dietary sources only. Foods that contain substantial amounts of selenium are nuts, fish, oysters, whole grains, chicken and turkey.
Considerations
Osteoarthritis is a chronic, degenerative condition that may lead to disability if not treated adequately. Follow your doctor's recommendations. The U. S. Food and Drug Administration has not approved selenium for the management of osteoarthritis, and it should not be used to replace any conventional drugs you are currently taking.
