Glycomacropeptide (GMP) is a protein naturally low in phenylalanine. Protein substitutes based on GMP are regularly perceived to be more palatable than those based on amino acids
1,2. Palatability of protein substitutes is key to compliance,
3 making GMP an ideal alternative protein source for Phenylketonuria (PKU).
