L-Carnitine is formed from the amino acids L-lysine and L-methionine in the body for the purposes of fatty acid metabolism.
Once fatty acids are transported to the mitochondria (the powerhouse centers of cells responsible for energy production) they are converted to usable forms of energy. The L-Tartrate version of L-Carnitine has been shown to be superior to L-Carnitine for muscle recovery and maintaining a hormonal balance. L-Carnitine L-Tartrate promotes an appropriate hormonal balance by improving androgen receptor activity. Its ability to promote recovery from high-intensity exercise makes it a dual threat as a training and fat loss aid.
