Aspartic acid (aspartate) is one of the most common amino acids in the typical diet. As with methanol and phenylalanine, intake of aspartic acid from aspartame is less than would be expected from other dietary sources. [10] [52] At the 90th percentile of intake, aspartame provides only between 1% and 2% of the daily intake of aspartic acid. [10]

Aspartic acid is not an essential amino acid, which means that it can be synthesized from central metabolic pathway intermediates in humans, and does not need to be present in the diet. In eukaryotic cells, roughly 1 in 20 amino acids incorporated into a protein is an aspartic acid, [ 26 ] and accordingly almost any source of dietary protein ...
