Vitamin C as a potent antioxidant, can prevent or slow cell damage caused by free radicals, hence prevent diseases. It also contributes to your immune defense system by supporting multiple cellular functions of your body's adaptive immune systems. Vitamin C helps encourage the production of white blood cells known as lymphocytes and phagocytes, which help protect the body against infection. Vitamin C helps these white blood cells function more effectively while protecting them from damage by potentially harmful free radicals. Free radicals are unstable molecules that the body produces as a reaction to environmental and other pressures. They can increase the risk of inflammation and various health issues.

Vitamin C scavenge free radicals from the body cells, thus prevent or reduce the damage caused by oxidation.
