Under normal circumstances, free radicals in the human body are in a dynamic balance of continuous production and removal. Free radical scavengers can remove excess free radicals generated in the body's metabolic process, so it is an important active substance that can improve human health. Free radical scavengers include antioxidants (VE, VC, β-carotene, reduced glutathione) and antioxidant enzymes (superoxide dismutase SOD, catalase CAT, glutathione, peroxidase GSH-PX).


Free radical scavengers can reduce the damage of free radicals to life macromolecules and tissue cells, and have the effect of preventing diseases and delaying aging.
