Aspartic acid, also called asparaginic acid, is one of the nonessential amino acids. "Nonessential" means that our bodies produce it even if we don't get this amino acid from the food we eat.
Aspartic acid helps every cell in the body work. It plays a role in:
- Hormone production and release
- Normal nervous system function
Plant sources of aspartic acid include:
- Legumes such as soybeans, garbanzo beans, and lentils
- Peanuts, almonds, walnuts, and flaxseeds
Animal sources include:
