L-Carnitine is actually not a peptide, but a naturally occurring amino acid derivative. It plays a crucial role in energy production by transporting fatty acids into the mitochondria, where they’re burned for fuel. In other words, it helps convert fat into usable energy. While L-Carnitine is not a peptide, it is often used in supplement form—either orally or as an injection—for its potential to support fat metabolism, athletic performance, and recovery.
