PKU sphere – GMP-Based Low-Phenylalanine Formula for Phenylketonuria (PKU)

PKU sphere is a specially formulated powdered medical food designed to support the dietary management of Phenylketonuria (PKU) using glycomacropeptide-(GMP) based protein—the first of its kind from Vitaflo®. Designed for use from age 3 years and up, it offers families and caregivers a more palatable, convenient protein substitute option under medical supervision.

Key Features & Benefits

• GMP-Dominant Protein Source: Uses glycomacropeptide (GMP) from whole protein sources—a protein naturally very low in phenylalanine—supplemented with essential and non-essential amino acids to meet nutritional needs in PKU management.
• Pre-Measured Packets for Easy Dosing: Available in sizes “15” (15 g protein equivalent) and “20” (20 g protein equivalent) with pre-measured packets. No weighing required makes preparation simpler for daily use.
• Low Volume, High Flexibility: The “20” packet, for example, mixes into a small volume (~120 mL/4 fl oz) while delivering 120 calories and 20 g protein equivalent—helpful for individuals managing fluid or portion size.
• Wide Variety of Flavours: Available in multiple flavours (Vanilla, Red Berry, Chocolate, Banana, Lemon) to enhance taste acceptance and dietary compliance.
• Micronutrient-Rich: Includes a broad spectrum of vitamins and minerals to address nutrient gaps common in low-protein PKU diets.

How to Use

• Choose the correct packet size (15 g or 20 g PE) and flavour as prescribed by your specialist.
• Mix one packet with the recommended volume of permitted fluid (as directed by your dietitian or clinician).
• Consume under medical supervision. Suitable for oral use and from age 3 years onward.
• Store unopened packets in a cool, dry place. Once prepared, follow instructions for consumption and discard any unused portion according to your clinician’s guidance.

Important Things to Know

• This product is a food for special medical purposes and must be used under the supervision of a healthcare professional experienced in PKU management.
• It is not intended as a sole source of nutrition, but as part of a comprehensive low-phenylalanine diet.
• Because each individual’s PKU dietary plan is unique (based on age, weight, metabolic control and phenylalanine tolerance), dosing and usage must be determined by a metabolic dietitian or physician.
• Individuals with allergies (e.g., milk or other protein sources) should check ingredient labels carefully.
• Flavoured options may contain small amounts of sugar—check with your dietitian if your plan limits sugars.
