superoxide dismutase (SOD)

Superoxide dismutase is an enzyme naturally present in all body cells that protects against the destructive effects of superoxide, a byproduct of the cell's use of oxygen. It has been suggested that the level of this enzyme present in a cell is an important factor in influencing that cell's rate of aging. This idea is controversial within the scientific community. Research has been conducted on mice with SOD dietary supplements. Dietary supplements did not influence the SOD level in cells.
