L-Carnitine

L-Carnitine is a vitamin-like nutrient that may support energy production and fat metabolism.

L-Carnitine is most commonly used by athletes and by people wanting to manage their weight as it provides ergogenic support and possibly promotes glycogen sparing in the course of prolonged exercise. This means that L-Carnitine is able to support the body to burn fat for energy, rather than glycogen - this has a double-whammy effect. It assists the body to support fat buring and it assists in providing prolonged energy.

You'll either find L-Carnitine on it's own for endurance athletes or as a part of a weight management complex for dieters.
