What it is

Ascorbic acid is a form of vitamin C, an essential nutrient for human health. It can be produced synthetically through a chemical process or derived from natural sources like corn or citrus fruits. It is commonly manufactured using fermentation and chemical synthesis.

Why it's used

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 while high doses can cause mild digestive upset, it is considered safe at levels typically found in food. International bodies like JECFA have evaluated ascorbic acid, and it is widely used globally. There are no significant controversies regarding its use as a food ingredient.

Allergen info
