What is in NutraSweet? It tastes good and doesn’t leave a bitter aftertaste like saccharin.
NutraSweet is the brand name of aspartame. Aspartame contains two amino acids, aspartic acid, and phenylalanine. Together they make foods taste sweeter. Persons with PKU (phenylketonuria) cannot use aspartame because it would raise their blood levels of phenylalanine. PKU is an inherited disease and is tested for at birth.
There are many foods on the market today that contain aspartame. One quart of diet cola contains about 100 milligrams of aspartame.
