Lysine is found in large amounts in foods such as: fatty fish (eg halibut, salmon, cod, mackerel, tuna, sardines, herring), eggs, yellow and cottage cheese, dairy products, red meat, poultry (chicken, turkey), liver, soy products, cocoa, wholemeal bread, almonds, buckwheat, green peas, red beans, parsley and sesame seeds.
