Acetyl-L-Carnitine is one of the body’s basic building blocks, an amino acid that is involved in the production of energy, healthy heart and brain function, muscle movement, the metabolism of cells and many other functions.
The body is capable of converting Acetyl-L-Carnitine into the closely related L-Carnitine compound, which turns body fat into energy. It’s also able to convert in the other direction. Your body makes both of these substances in the liver and kidneys, and they are stored for future use at various sites around the body: in skeletal muscles, brain, and heart, for instance.
As a supplement, this amino acid reacts on the mitochondria in the cells. Because they are involved in the production of energy, boosting their production may lend an overall increase to physical and mental performance.
