Question: what is the difference between l carnitine and carnitine?
Answer: In the body, acetyl-L-carnitine is made from L-carnitine that the body produces naturally. L-carnitine is an amino acid. Amino acids are usually used as building blocks for proteins, but L-carnitine is not. Instead, L-carnitine and acetyl-L-carnitine are used to help the body turn fat into energy.
