L-Carnitine is a naturally occurring compound that plays a crucial role in energy production. It helps transport fatty acids into the mitochondria, the powerhouse of cells, where they are converted into energy. This process is essential for maintaining energy levels, especially during physical activity. Many people take L-Carnitine as a dietary supplement to support weight loss and enhance athletic performance. While some studies suggest it may help improve exercise endurance, results can vary. It's important to consult a healthcare professional before starting any supplement regimen to ensure safety and effectiveness.
