As with all amino acids, excellent sources of phenylalanine include meat, poultry, fish, eggs, and dairy products.
Grains, cereals, legumes, and nuts provide additional dietary sources of phenylalanine.
Most people consume more protein than is needed by the body; consequently, a deficiency oh phenylalanine is rare except in cases of malnutrition.
