How L-Carnitine / Levocarnitine works
L-Carnitine / Levocarnitine is a naturally occurring amino acid derivative that helps the body produce energy from fat.
It works by transporting long-chain fatty acids into the mitochondria, the energy-producing structures within cells. Inside the mitochondria, these fatty acids are broken down through a process called beta-oxidation to generate energy.
By supporting this process, L-Carnitine / Levocarnitine helps correct deficiency and supports energy production in tissues such as the heart and skeletal muscles that rely heavily on fat for fuel.
