Consumer Advice
Leucine is one of the essential amino acids that make up proteins; the body cannot produce it and must obtain it from food. In food it is used mainly as a nutritional fortifier and flavour improver, common in sports nutrition products and protein supplements, where it supports muscle building and recovery. As a normal dietary component it is very safe at usual intake levels.
