2020-09-28 19:55 Superoxide dismutase is an enzyme that helps break down potentially harmful oxygen molecules in cells, which might prevent damage to tissues. It is being researched to see if it can help conditions where oxygen molecules are believed to play a role in disease. Superoxide dismutase is taken by mouth for removing wrinkles, rebuilding tissue, and extending the length of life. However, there is no evidence that superoxide dismutase products that are taken by mouth are absorbed by the body. As a shot, superoxide dismutase is used for treating pain and swelling (inflammation) caused by osteoarthritis, sports injuries, and rheumatoid arthritis; a kidney condition called interstitial cystitis; gout; poisoning caused by a weed-killer called paraquat; cancer; and lung problems in newborns. Superoxide dismutase is also given as a shot for improving tolerance to radiation therapy, improving rejection rates in kidney transplantation, and minimizing heart damage caused by heart attacks.
