L-Carnitine is a naturally occurring amino acid derivative that plays an essential role in energy production. It helps transport long-chain fatty acids into the mitochondria of cells, where they are oxidized and converted into energy. The body primarily synthesizes L-carnitine in the liver and kidneys and stores it in areas like skeletal muscles, the heart, and the brain, which are highly reliant on fatty acids for energy [1][3].
L-carnitine supplements are often marketed for weight loss and athletic performance due to their role in fat metabolism. Research suggests benefits in heart health, exercise recovery, and potentially supporting cognitive function. However, its effectiveness as a supplement varies based on individual health factors and activity level [2][5].
