PKU sphere 15 and PKU sphere 20 Overview

Vitaflo PKU sphere is a powdered protein substitute designed for the dietary management of phenylketonuria, or PKU. It is based on glycomacropeptide (GMP), which is naturally low in phenylalanine and widely considered more palatable than amino acid-based protein substitutes. This formula contains a GMP-dominant protein source supplemented with essential and nonessential amino acids, fat (including DHA), and carbohydrate. It also provides a full range of vitamins and minerals to support adequate intake of nutrients commonly lacking in PKU diets.

PKU sphere is available in two packet sizes and multiple delicious flavors. It can be mixed with water or incorporated into drink recipes using permitted ingredients. The convenient packaging allows easy dosing with no weighing or measuring, meeting the demands of an on-the-go modern lifestyle. Both sphere15 and sphere20 mix with a low volume of only 4 ounces, or they can be easily prepared to the individual's preferred volume.

Frequently Asked Questions (FAQs)

What is GMP?
Glycomacropeptide, or GMP, is a protein substitute derived from the whey protein produced during cheese-making. It's naturally low in phe, making it a good protein equivalent for PKU formulas.

How is PKU sphere different from other protein substitutes?
Unlike many standard PKU formulas, this protein substitute is GMP-based. GMP is an exciting innovation for PKU formulas because it tastes different than amino acid-based protein substitutes. Many users prefer the taste, smell, and non-gritty texture to other formulas, which helps them stay on-diet.

How much should I consume each day?
This is dependent on each individual's unique needs and circumstances. Your medical team will help you determine exactly how much and which PKU sphere product is the right choice for you.

Each 27-gram sphere15 packet contains 15 grams of protein equivalent with 28 milligrams of phenylalanine.
Each 35-gram packet of sphere20 contains 20 grams of protein equivalent with 36 milligrams of phenylalanine.

How do I prepare this protein equivalent drink?
It's easy to mix up a PKU sphere drink, even if you're out and about. The powder is premeasured in travel-friendly packets, and it looks and smells like any typical protein drink, ensuring discretion. The drink is ready to enjoy with three simple steps:

Measure 120 mL (4 fluid ounces) of cold water into a shaker or a cup with lid.
Add one packet of PKU sphere.
Make sure the lid is secured and shake until the powder is completely dissolved.
