leucine
Leucine is one of the building blocks of protein and belongs to a small group called branched-chain amino acids. The body cannot make leucine on its own, so it must come from food such as meat, dairy, eggs, beans, and some nuts. Leucine plays a special role in telling muscle and other tissues to start making new proteins, which is why it is often highlighted in discussions about muscle growth and recovery. It acts as a signal to cellular machinery to increase protein production, helping tissues repair after exercise or injury. Because of its signaling role, leucine is important for people who are growing, healing, or trying to preserve muscle during aging. Some people use leucine-containing supplements to support recovery after intense workouts or to slow muscle loss in older adults, but balance and overall diet quality are important. Very large amounts of any single nutrient can have downsides, so it’s best to get leucine as part of a varied diet or under guidance from a health professional if using supplements. Leucine also interacts with wider metabolic pathways, so changes in intake can affect energy balance and other processes in the body.
