Made With GMP — Designed to Taste Better²

PKU GMPro Delight® is made using GMP (glycomacropeptide), a naturally derived protein source from milk³. Compared with many traditional protein substitutes, GMP products are known for offering a gentler taste and smoother texture².

This means:

• A more pleasant drinking experience
• A lighter mouthfeel
• A protein substitute that feels closer to everyday food

Enjoying the taste makes it easier to stay consistent, and consistency matters.

Flavours You’ll Actually Look Forward To

PKU GMPro Delight® is available in two refreshing flavours:

• Berry
• Tropical

Both flavours are mild, fruity, and easy to enjoy on their own or mixed into suitable drinks. Add PKU GMPro Delight® to smoothies or serve it chilled for a fresh, light option at any time of day.

Convenience That Makes Life Easier

PKU GMPro Delight® was designed for everyday moments.

• Ready-to-use sachets — just tear, mix, drink
• No weighing or measuring
• Portable and discreet — easy to take anywhere
• Low volume — mixes with around 140 mL of liquid

That means less preparation, less attention, and less disruption — especially when you’re out and about.

A More Comfortable Way to Stay on Track

Many people say the hardest part of using protein substitutes isn’t remembering to take them, it’s wanting to take them. Strong smells, heavy textures, or unpleasant tastes can make routines harder to maintain.

PKU GMPro Delight® was created to remove those barriers.

The result:

• Something that feels lighter
• Something that’s easier to finish
• Something that fits into social situations more naturally

It’s not about changing your day — it’s about supporting it.
