N-Acetylneuraminic Acid is a derivative of neuraminic acid and a naturally occurring amino sugar. It is widely distributed in nerve tissue and breast milk and is an essential nutrient for human neural development. It has multiple physiological functions such as anti-aging, promoting neural development, improving cognition and enhancing immunity. In recent years, N-acetylneuraminic acid has been approved as a new food ingredient. It is also used in infant formula, nutritional supplements, cosmetics and other fields.
