title: Results of loading doses of aspartame by two phenylketonuric (PKU) children compared with two normal children.
abstract: Separate tolerance tests with aspartame at 34 mg/kg-day and phenylalanine at 19 mg/kg-day were compared. The results reveal that slight serum elevation of phenylalanine and tyrosine occurred in the two PKU and the normal healthy adolescents. It would appear that the phenylalanine in the sweetener aspartame is small enough to be of little clinical significance.
