L-carnitine is a naturally occurring amino acid derivative widely used in Australia for its role in energy production and metabolism. It helps transport fatty acids into the mitochondria, where they are converted into energy. L-carnitine is commonly used in both human and animal nutrition to support weight management, muscle function, and overall endurance. In veterinary care, it is often recommended for pets with heart conditions or metabolic disorders. Athletes and individuals seeking improved exercise performance also incorporate L-carnitine into their diets. Proper dosage and medical guidance are essential to maximize its benefits and ensure safe usage.
