Phenyl-Free 1 Infant & Toddler PKU Formula

Phenyl-Free 1 from Reckitt Benckiser is a phenylalanine-free powder formula developed specifically for infants and toddlers diagnosed with phenylketonuria (PKU), an inherited metabolic disorder in which the body cannot break down phenylalanine. Because uncontrolled phenylalanine levels can affect neurological development in these early years, a specialized formula that supplies complete nutrition without this amino acid is not a convenience — it's a medical necessity.

The Reckitt Benckiser Phenyl-Free 1 Powder Formula (892601) comes in a 1 lb. can providing roughly 500 calories, and is intended as the primary nutrition source or a supplement for the youngest PKU patients. It delivers the protein equivalents, fat, carbohydrates, vitamins, and minerals a growing child needs, while omitting phenylalanine entirely. Parents typically use it alongside carefully measured amounts of standard formula or breast milk so that the child receives the small, tolerated quantity of phenylalanine their individual diet plan allows — a balance directed by a metabolic specialist or registered dietitian.

Preparation follows the same routine as conventional powdered formula: measured scoops mixed with the appropriate volume of water. Because dosing is tied to a prescribed phenylalanine allowance and monitored blood levels, families should always confirm mixing ratios and daily intake with their care team rather than adjusting on their own.

As a child grows and dietary tolerance changes, the formula regimen usually transitions to age-appropriate options.

Families managing other amino acid metabolic conditions may also reference BCAD 1 for related medical nutrition needs.
