L-Carnitine

L-carnitine is a derivative of lysine and methionine which are amino acids.  The L-carnitine gets synthesized primarily in the organs of the liver and kidneys.  From here it can be transported to other areas of the body.

L-carnitine is predominantly found in the tissues that utilize fatty acids.  It is here that it is in the highest concentrations. 

In recent years energy drinks have become increasingly common.  Not only this, but their ingredient lists are becoming ever more complex.  Caffeine and sugar are no longer the only things providing energy drink users with a quick pick me up.  Today there are a host of other energy enhancing ingredients on the menu.
