# L-Carnitine: Benefits, Uses, 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. While your body produces L-Carnitine in the liver and kidneys, it can also be obtained through dietary sources like red meat, fish, poultry, and dairy products.
