Glytactin BUILD 20/20 — High Protein, Ultra-Low Phenylalanine Formula for PKU

Glytactin BUILD 20/20 is a powdered medical food designed specifically for individuals age 1 year and older with Phenylketonuria (PKU). It offers 20 grams of GMP-based protein in each serving, with a very low phenylalanine content (~20 mg Phe) — helping support your daily protein needs while respecting the metabolic requirements of a PKU diet.

Key Features & Benefits

• High protein equivalent (20 g PE) with ultra-low Phe: Each serving delivers 20 g of protein equivalent while containing only ~20 mg of phenylalanine — offering more protein with fewer Phe concerns compared to many other GMP-based formulas.
• Complete nutrition: Formulated with a full profile of vitamins, minerals, DHA (docosahexaenoic acid), and probiotics to help support overall health, growth and digestion in PKU patients.
• Low-calorie, flexible mixing: Delivers approximately 50 calories per 10 g protein equivalent (≈110 calories per 20 g protein in some formats) and can be mixed with water or permitted beverages or used to boost the protein of other low-Phe foods and formulas.
• Neutral flavour & versatile format: Comes in varieties like vanilla, chocolate, smooth, and raspberry lemonade — making it easier to fit into daily diet routines and taste preferences.
• GMP-based innovation: Made using GMPure™ technology (glycomacropeptide from whey) which is inherently much lower in phenylalanine than standard amino-acid formulas — helping improve variety and quality of life for PKU management.

How to Use

• Medical supervision required: Use this product only under the guidance of your metabolic specialist or dietitian — they will determine the number of servings and how to incorporate it into your overall low-Phe diet.
• Prepare easily: Add one packet (or the amount prescribed) to approximately 120 mL (≈4 fl oz) of water or other approved beverage. Shake or stir until fully blended. Serve chilled for best taste.
• Flexible use: You may also add it into permitted low-protein foods (e.g., smoothies, oatmeal) to “build up” protein levels while maintaining low Phe.
• Storage: Store unopened packet/can in a cool, dry place. Once opened/mixed, consume according to manufacturer instructions (typically within 24 hours when refrigerated).

Important Things to Know

• This is a medical food for special dietary use specifically for PKU and must be used under medical supervision. It is not intended for healthy individuals without PKU.
• It is not a sole source of nutrition — your diet must still include prescribed natural protein (with controlled Phe), fluids, and other foods under your clinician’s plan.
• Because each person with PKU has a unique phenylalanine tolerance and protein target, do not adjust your dose or discontinue other components of your diet without consultation.
• Contains milk and soy ingredients; if you have allergies, check with your dietitian.
• Always check flavour and version (vanilla, chocolate, smooth, raspberry lemonade) and ensure you follow your dietitian’s instructions for preparation and usage.
