What Is Aspartame?

A low-calorie artificial sweetener approximately 200 times sweeter than sucrose. Composed of two amino acids — aspartic acid and phenylalanine — linked by a methyl ester bond.

How Does It Work?

Hydrolyzed in the gastrointestinal tract into aspartic acid, phenylalanine, and methanol. These are normal dietary components metabolized through standard pathways. Phenylalanine is a concern for individuals with phenylketonuria (PKU). The methanol produced is in quantities far below those from fruit consumption.

Commonly found in: Diet Coke, Sugar-free gum, Crystal Light, Sugar-free Jell-O, Diet Snapple
