Clinical Nutrition Assessment Section, US Food and Drug Administration, Washington, DC 20204. Aspartame, the methyl ester of the dipeptide formed from combining phenylalanine and aspartic acid, was approved by the US Food and Drug Administration (FDA) in July 1981. FDA monitors complaints from consumers and health professionals through the Adverse Reaction Monitoring System, a passive surveillance program FDA has received 251 reports of seizures that have been linked to ingestion of aspartame by consumers.
