# L-Carnitine: Benefits, Sources, and Potential Side Effects
## What is L-Carnitine?
L-Carnitine is a naturally occurring amino acid derivative that plays a crucial role in energy production by transporting fatty acids into your cells’ mitochondria. The mitochondria act as engines within your cells, burning these fats to create usable energy.
Your body can produce L-carnitine from the amino acids lysine and methionine. For your body to produce it in sufficient amounts, you also need plenty of vitamin C. In addition to the L-carnitine produced in your body, you can also obtain small amounts by eating animal products like meat or fish.
