Cookbook:Lofenalac  Lofenalac

Lofenalac (pronunciation:Lo-fen-alac) is a registered, trademarked infant powder formula prescribed to replace milk in the diets of Phenylketonuria sufferers in the infant and child stage. It is not recommended for non-PKU patients.[2] In 1972, Lofenalac was declared a food by the FDA, for regulatory purposes.[3]

Initially the only available formula recommended was made by Mead Johnson. Others, including Albumaid XP™, Cymogran™, and Minafen™, have since been developed in Britain.[4] Medical texts often recommend Lofenalac.[5][6][7]

Lofenalac can be rather expensive to purchase and few retailers stock it. The taste and smell has been described by adult users as "medical" and offensive,[8] although infants do not mind the flavor and children often consume it without complaint for some years.[9]
