What is Ascorbic Acid

Ascorbic acid (vitamin C, sodium ascorbate, ascorbate) is a water-soluble vitamin found in fruits and vegetables such as citrus fruits and green peppers.

Ascorbic acid is a free radical, an antioxidant scavenger, and plays a major role in oxidation-reduction reactions.

Ascorbic acid is a cofactor for enzymes involved in the biosynthesis of collagen (essential for tissue maintenance and repair), carnitine, and neurotransmitters. Humans cannot synthesize ascorbic acid endogenously and a lack of dietary intake can lead to scurvy.

Intravenous ascorbic acid is FDA-approved for the treatment of scurvy.

Vitamin C is also most frequently used as a nutritional supplement and as an adjunct in wound healing.

It also is used as a treatment of methemoglobinemia as an alternative in patients who cannot receive methylene blue and with deferoxamine in the treatment of chronic iron toxicity.

Vitamin C deficiency is highly prevalent during critical illness and high-dose vitamin C has been used in patients with sepsis, trauma, and burns with beneficial effects and no adverse effects.

Ascorbic acid has also been used for a variety of ailments including the common cold, gum infections, acne, depression, fertility, and cancer; however, these claims have not been substantiated and vitamin C is not recommended for these purposes.
