What it is

Ascorbic acid is a synthetic form of vitamin C, an essential nutrient found naturally in many fruits and vegetables. It is typically manufactured through a chemical process involving glucose, often derived from corn.

Why it's used

Manufacturers add ascorbic acid to foods as an antioxidant to prevent spoilage and maintain color, and as an acidulant to add tartness. It is commonly found in baked goods, cured meats, beverages, jams, and jellies.

Health notes

Ascorbic acid is generally recognized as safe (GRAS) by the FDA for use as a food additive. It is an essential nutrient, and adequate intake is important for immune function and collagen production. JECFA and EFSA have evaluated ascorbic acid and found it to be safe. High doses may cause digestive upset in some individuals, but this is rare at typical dietary intake levels.

Allergen info

Ascorbic acid is not derived from any of the nine FDA major allergens and does not contain gluten.
