Inborn errors of metabolism are rare disorders caused by genetic defects that affect the body's ability to break down particular nutrients found in food e.g. amino acids. Most often inherited from both parents, they are usually caused by defects in enzymes that help break down ('metabolise') food. This in turn can lead to a harmful build-up of certain chemicals, which, if not managed, can cause a wide array of symptoms including delays in physical and mental development.

      The role of nutrition

      Management of inborn errors of metabolism is usually through a lifelong commitment to a restricted diet. In the example of the amino acid disorder Phenylketonuria (PKU), individuals cannot break down the amino acid phenylalanine, which leads to a build-up on the brain. A build-up of this kind can cause long-term health issues, including irreversible brain damage. Since amino acids such as phenylalanine are the building blocks of the protein we eat, PKU patients must stick to a low-protein diet, alongside supplementation of the essential and non-essential amino acids that our bodies need to function properly.

      Nutricia is the world's leading metabolic nutrition company supporting the greatest number of people across the widest variety of inborn errors of metabolism. We use our unique nutritional expertise to develop high-quality products that help make the lives of patients and their families a little easier.
