Caution

Amino Acid

Aspartic acid is a non-essential amino acid that can be derived from both plant and animal sources, commonly used in protein-rich foods and supplements.

What is Aspartic Acid?

Aspartic acid is an alpha-amino acid that is used in the biosynthesis of proteins. It is one of the 20 proteinogenic amino acids and is categorized as a non-essential amino acid, meaning it can be synthesized by the human body. Aspartic acid exists in two forms: L-aspartic acid, which is biologically active, and D-aspartic acid. It is involved in the urea cycle and gluconeogenesis and is found in a variety of foods, especially those high in protein such as meat, eggs, and soy products.

Why People Avoid Aspartic Acid

People may avoid aspartic acid if they follow a strict vegetarian or vegan diet and the source of the amino acid is not specified on the product label. Aspartic acid can be derived from both plant and animal sources, so without specific labeling, it's unclear whether it is suitable for vegetarians. Consumers concerned about the source should contact manufacturers for clarification.
