No, aspartame is a chemically formed sugar substitute that bonds L-phenylalanine to aspartic acid. On the other hand, the aspartic acid which we use in Emergen-C, is an amino acid readily found in foods such as fish, legumes, dairy, whole grains, eggs, meats, nuts, and seeds. We use this pure L-Aspartic Acid which has the same structure as that found in foods.
