What it is

L-valine is an essential amino acid, meaning the body cannot make it and it must be obtained from food. It is one of the building blocks of protein. L-valine can be produced through fermentation using microorganisms or by breaking down proteins.

Why it's used

L-valine is often added to foods as a nutrient, particularly in sports drinks, protein supplements, and infant formulas. It is used to help build and repair muscle tissue and can contribute to overall protein synthesis in the body.

Health notes

In the US, L-valine is generally recognized as safe (GRAS) by the FDA when used as a nutrient. International bodies like JECFA and EFSA have evaluated amino acids, and it is considered safe at typical dietary levels. Research suggests that adequate intake of essential amino acids like L-valine is important for muscle growth and repair, especially after exercise.

Allergen info

L-valine is not derived from any of the nine FDA major allergens. It does not contain gluten.
