Vitamin C Citric Acid

Vitamin C, also known as ascorbic acid, is a water-soluble vitamin found naturally in many fruits and vegetables. It is often produced commercially through chemical synthesis, typically starting with glucose derived from corn or other plant sources. It plays a vital role in immune function, collagen production, and as an antioxidant.

Manufacturers add Vitamin C to foods as an antioxidant to prevent spoilage and maintain color, and as a nutrient to fortify products. It is also used as an acidity regulator to enhance flavor in beverages, jams, and processed fruits. You'll find it in fruit juices, canned fruits, baked goods, and processed meats.

Vitamin C is generally recognized as safe (GRAS) by the FDA when used as a nutrient or antioxidant. The FDA has established it as an essential nutrient. JECFA and EFSA have evaluated Vitamin C and established acceptable daily intake levels. While generally safe, very high doses can cause digestive upset in some individuals. Research suggests Vitamin C may support immune function, but it is not a cure for the common cold.
