Valine

Valine is one of the essential amino acids, meaning the human body cannot synthesise it and must obtain it from the diet. It is a component of proteins found naturally in many foods, including meat, dairy products, grains, and legumes. It can also be produced industrially through fermentation processes using microorganisms.

Valine is often added to foods and drinks as a source of protein or amino acids, particularly in sports nutrition products like energy drinks and supplements. It may also be used in some processed foods to contribute to flavour or nutritional profile. Its presence is often linked to the functional claims of these products.

Valine is not listed as a food additive on the Register of Food Additive Authorisations, indicating it is used as a food ingredient rather than an additive in the UK. As an essential amino acid, it plays a vital role in bodily functions. The European Food Safety Authority (EFSA) has evaluated amino acids for specific uses, such as in foods for special medical purposes. Evidence does not suggest adverse health effects from typical dietary intakes of valine found in food.
