isoleucine

Isoleucine is one of the essential amino acids, meaning your body cannot produce it and it must be obtained through the diet. It plays a key role in muscle repair, energy production, and immune function. Found in protein-rich foods like meat, eggs, dairy, and certain plants, isoleucine helps support athletic performance and overall health. It is part of the building blocks that make up proteins, contributing to the growth and maintenance of tissues. Because it's essential, consuming enough isoleucine is important for maintaining optimal body functions, especially for active individuals or those recovering from injury.
