What is PKU?

Phenylketonuria (PKU) is a rare but potentially serious inherited disorder.1 People with PKU can’t break down the amino acid phenylalanine (Phe), which is in all foods containing protein.1,2 If left untreated, and levels of Phe get too high, serious medical problems can occur.2

How is PKU managed?

PKU can be managed with:3-5

  • A very limited diet
  • Specially manufactured low-protein foods
  • Phe-free protein substitutes

Guidelines recommend that the majority of people with PKU undergo treatment for life4,5

What can happen if PKU is poorly managed?7

If patients don’t stick with their PKU diet it could cause:

Problems with concentration; Depression; Anxiety; Tiredness; Mild learning difficulties; Problems with behaviour

Not sticking with the PKU diet is commonly attributed to a lack of palatability.5,8,9 That’s why we’ve developed a range of palatable protein substitutes designed to help people with PKU stick with their diets and stay healthy.
