L-carnitine is a nitrogenous compound that contributes to fat metabolism. Carnitine plays a vital role in making fatty acids available to muscle tissue.

Carnitine is also found naturally in cells that use fat as a source energy.

Carnitine is present throughout the body, including the heart, muscles, liver and kidneys.

The carnitine also helps the body use energy stores to fuel muscle contractions, which helps support endurance exercise and recovery from high-intensity exercise.
