Aspartic acid is not an essential amino acid, which means that it can be synthesized from central metabolic pathway intermediates in humans. However, aspartic acid is found in:
Animal sources: oysters, luncheon meats, sausage meat, wild game
Vegetable sources: sprouting seeds, oat flakes, avocado asparagus, young sugarcane, and molasses from sugar beets 
Dietary supplements, either as aspartic acid itself or salts (such as magnesium aspartate)
