See: Glutamic Acid. Aspartic Acid is a nonessential amino acid–amino acids being the building blocks of proteins. This amino acid is nonessential because the body can produce it using other, essential, amino acids. Aspartic acid is similar to glutamic acid in function.
Since this amino acid can be produced by modifying existing essential amino acids in the body, consumption of aspartic acid is not technically required, but it is still strongly suggested, so as to allow the essential amino acids to fulfill their other purposes.
