L-carnitine is a naturally occurring amino acid derivative that the body makes from lysine and methionine, and it helps turn fat into energy by moving fatty acids into cell mitochondria.
• Energy Production: It acts as a shuttle to transport long-chain fatty acids into the mitochondria so they can be burned for fuel.
• Heart Health: It supports heart muscle function, may help reduce blood pressure and cholesterol, and is often studied in connection with heart failure or angina.
• Brain Function: The acetyl form (acetyl-L-carnitine or ALCAR) is researched for age-related cognitive decline and memory support.
• Exercise and Recovery: While popular for boosting athletic performance, clinical evidence for muscle recovery or fat loss in healthy, well-nourished individuals is mixed.
