XPhe Junior

Super-concentrated amino acid mixture for school-age children with PKU

XPhe Junior is a Food for Special Medical Purposes (FSMP) designed for children with phenylketonuria (PKU) or hyperphenylalaninaemia (HPA) aged 7 to 14 years. The formula contains highly purified L-amino acids free from phenylalanine and provides the protein equivalent without the additional burden of phenylalanine intake.

XPhe Junior follows the concept of low-volume metabolic therapy, offering a high concentration of amino acids in a small intake volume, which helps improve compliance in young children.

The formula does not contain fat or carbohydrates and does not provide additional calories, allowing for more flexible adaptation of the energy component of the diet.

Clinical role in PKU management
XPhe Junior replaces the portion of dietary protein that cannot be obtained from the child's natural food sources due to impaired phenylalanine metabolism. The daily amount of the mixture is determined individually based on age, body weight, phenylalanine tolerance, and the results of metabolic monitoring.

The daily dose should be divided into 3–5 separate servings throughout the day. The formula can be used either on its own or in combination with other products in the XPhe range, according to the patient's individual dietary plan.

Support for an active school lifestyle
XPhe Junior is designed for school-age children who need consistent amino acid support throughout the day. The high concentration of amino acids in a small volume can make it easier to maintain daily adherence to dietary therapy, including taking the product at school, during lessons, or during active leisure time.
