Phenylalanine Amounts Phenylalanine and other amino acids are naturally occurring non-additives found in the protein of foods.  Due to some dietary restrictions these levels must be monitored. Our Phenylalanine amounts are obtained by three methods: Outside laboratory testing contracted by Ener-G Foods, Inc.; Computations based on a nationally recognized database; and For products manufactured by other companies, the phenylalanine amounts may be supplied by that manufacturer. It is important to remember that true Phenylalanine amounts may vary from those amounts listed in the product ingredients because of several factors, including baking or cooking variations. > CLOSE WINDOW
