Overview

NOW Foods L-Carnitine provides 1000mg of L-carnitine tartrate per tablet, the amino acid derivative responsible for transporting long-chain fatty acids into the mitochondria for beta-oxidation (fat burning). L-carnitine tartrate is the most studied form for exercise performance and recovery, with research showing reduced muscle damage markers and improved recovery after intense training. The body produces carnitine from lysine and methionine, but production may be insufficient during intense exercise or in vegetarians/vegans who get minimal dietary carnitine.
