L- Carnitine


L-carnitine is a chemical that is made in the human brain, liver, and kidneys. It aids in the metabolic process of converting fat into usable fuel.

L-carnitine is important for heart and brain function, muscle movement, and many other body processes. L-carnitine can be broken down further in the body into acetyl-L-carnitine and propionyl-L-carnitine. But whether or not the benefits of these other carnitines are the same is unclear.

L-carnitine is used to increase L-carnitine levels in people whose natural level of L-carnitine is too low. There is no solid scientific evidence to support the use of L-carnitine for conditions involving the heart and blood vessels, severe kidney disease, and many others.
