L-Carnitine, a vital amino acid derivative, facilitates the transport of fatty acids into cells' mitochondria, converting them into energy crucial for powering muscles, the heart, and other tissues, thus boosting overall energy and endurance while reducing muscle fatigue. Administered as an injection for optimal absorption and effectiveness, L-Carnitine supplementation supports fat metabolism, enhances exercise performance by preserving glycogen stores, and may contribute to cardiovascular health benefits.
