XPhe Energy A provides additional energy through a combination of readily digestible carbohydrates and plant-based oils. This helps reduce the use of amino acids as an energy substrate after absorption and supports an anabolic metabolic profile.
The product may be particularly useful:
during periods of active growth
with high levels of physical activity
during sports training
in cases of inadequate weight gain
with reduced appetite
during periods of increased energy requirements or catabolic states

Flexible integration into the daily diet
XPhe Energy A integrates easily into the daily PKU diet and can be used as:
the main amino acid mixture serving
a metabolic snack
an additional energy source between meals
support during an active lifestyle or sports activities
The formula can be combined with other products in the XPhe range according to the patient's individual dietary plan.
Preparation method

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