What does OFR mean medically?

OFR medically refers to Oxygen Free Radicals, which are the root cause of aging and disease in humans and are health killers.
Oxygen is what we rely on for survival, life cannot exist without oxygen, but oxygen can also be harmful to the human body, because oxygen will become oxygen free radicals. Oxygen molecule is originally a stable double-atom structure, but if affected by ultraviolet light and stay up late and other factors, the oxygen atom will lose an electron, from harmless oxygen into oxygen free radicals, also known as OFR.
Oxygen free radicals are harmful to the human body, destroying the structure and function of cell membranes, destroying mitochondria, cutting off cellular energy, and destroying lysosomes. Moreover, can cause damage to the adhesives in the walls of blood vessels, making them susceptible to oozing and leaking blood, so that edema and purpura may occur. Oxygen free radicals attack, fatty acids on cell membranes to produce peroxides, aging the body.
To counteract oxygen free radicals is usually to use oxygen free radical scavengers or inhibitors such as vitamin C, vitamin E, and glutathione.
