What it is

Vitamin C, also known as ascorbic acid, is a water-soluble vitamin found naturally in many fruits and vegetables. It is an essential nutrient that humans cannot produce on their own. It is often manufactured synthetically for use as a food additive.

Why it's used

Vitamin C is primarily added to foods as an antioxidant to prevent spoilage and maintain color, especially in fruits and processed meats. It also acts as a nutrient to fortify foods like cereals, beverages, and dairy products, and can be used as an acidity regulator.

Health notes

The U.S. Food and Drug Administration (FDA) recognizes ascorbic acid as Generally Recognized As Safe (GRAS) when used as a nutrient or preservative. It is an essential nutrient for human health, playing a role in immune function and collagen production. High doses may cause digestive upset in some individuals. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated ascorbic acid.
