Supplement Guide: Carnitine >>>
Some background: Carnitine (and L-carnitine) helps the body break down fat and turn it into energy. It also increases the activity of certain nerve cells in the central nervous system.
An amino acid (so, a natural building block of proteins), carnitine is naturally produced by the body in the liver and kidneys. Guys looking to get more can find it in fish, poultry, red meat, and some types of dairy—or, of course, through over-the-counter supplements.
