Vitamin C or in chemical terms known as ascorbic acid (C6H8O6) is a water soluble substance and is available as a supplement, widely consumed by the public. Vitamin C is naturally found in red and yellow fruits and vegetables such as oranges, papaya, strawberries, and some vegetables (Dewi, 2015).

Most animals and plants can synthesize ascorbic acid for their own needs, but humans cannot produce it themselves because they do not have the enzyme gulunolactate oxidase, an enzyme that plays a role in the formation of ascorbic acid. Vitamin C plays an important role in many physiological processes in humans. Necessary for tissue repair in all parts of the body.

Important functions of vitamin C include the formation of proteins used to make skin, tendons, ligaments, and blood vessels for wound healing and scar tissue formation, to repair and maintain cartilage, bones, and teeth and to aid in the absorption of iron. It can also act as a reducing and limiting agent for metal nanoparticles (Devaki, 2017). Vitamin C is an antioxidant that plays a role in protecting the body from free radicals.

Free radicals are a form of reactive oxygen compounds, which are generally known as compounds that have unpaired electrons. Free radicals can be formed during normal metabolism, such as when food components are converted into energy forms.

In this metabolic process, electron leakage often occurs which easily forms free radicals such as superoxide and hydroxyl anions. Oxidizing substances or other free radicals can also come from outside the body such as cigarette smoke, car smoke, pollutants, and others (Ernawati, 2009).
