Superoxide Dismutase (SOD, EC1.15.1.1), with special physiological activity, is the primary substance in the body that scavenges free radicals. It can be divided into three types according to its different metal co groups, among which Cu/Zn SOD, the most common enzyme, is green and mainly present in the cytoplasm of the body cells.

It can be divided into three types according to its different metal co groups, among which Cu/Zn SOD, the most common enzyme, is green and mainly present in the cytoplasm of the body cells. The Cu/Zn SOD superoxide dismutase produced by our company is a genetically recombinant product, free from animal derived viruses, with high purity and good activity. Biochemical research: SOD can specifically eliminate harmful free radicals in the body, in order to relieve the damage caused by the oxidation of certain components in the body by free radicals. SOD, as a biochemical enzyme preparation, is widely used in clinical and scientific research, mainly focusing on patients with inflammatory diseases, especially in the treatment of rheumatoid arthritis, chronic multiple arthritis, myocardial infarction, cardiovascular disease, tumor patients, as well as radiation therapy for inflammatory disease patients. It assists the human body in regulating the endocrine system and improving immunity.
