SOD superoxide dismutase is also known as superoxide dismutase (SOD), if the supply of superoxide dismutase is too much it will be harmful to the body, destroying the normal physiological functions of the body and so on. Superoxide dismutase can play the role of antioxidant, anti-aging, etc. It can also be used in the treatment of diseases caused by superoxide radicals, such as oxygen toxicity, acute inflammation and so on. However, if the exogenous supply of superoxide dismutase is too much, the body is unable to maintain a certain amount of free radical level, which may easily lead to cell membrane damage, accelerate aging, as well as trigger inflammatory reactions, which may increase the chances of suffering from oncological diseases or autoimmune diseases. It is recommended to seek medical attention if abnormalities of superoxide dismutase occur.
