L-Carnitine — Uses, Dosage, Side Effects & Safety

Drug class: Health & Lifestyle Management

Overview

L-Carnitine is a naturally occurring nutrient and dietary supplement that plays a key role in energy production by helping the body convert fat into energy. It is used medically to treat primary and secondary carnitine deficiency, which can occur in people with certain genetic disorders, kidney disease, or those undergoing dialysis. L-Carnitine works by transporting long-chain fatty acids into the mitochondria, where they are broken down to produce energy. This process is essential for heart and muscle function. Patients should know that L-Carnitine is available in several forms and may be prescribed by a healthcare provider for specific medical conditions, or used as a supplement under medical supervision. Key points: Always use L-Carnitine as directed by your healthcare provider. Inform your doctor about all medications and supplements you are taking. Report any unusual side effects promptly.
