L-carnitine tartrate is one of 5 L-carnitine formulations. It benefits people who are looking for a fast-acting version of carnitine. Other forms of carnitine, like acetyl-L-carnitine, L-carnitine fumarate, and propionyl-L-carnitine, are used for more specialized functions.

L-Carnitine-L-Tartrate Stacking

If you want to learn how to boost metabolism most effectively, it’s helpful to consider combining L-carnitine-L-tartrate with other supplements that provide similar benefits. This is called “stacking,” and it is one of my favorite fat loss tips. When you use several different fat burning supplements at the same time, you can get all of the benefits at once.

GAT SPORT L-Arginine

I sometimes use GAT SPORT L-arginine as part of my stack because it does not interfere with me getting all of the L-carnitine benefits. Arginine is an inexpensive way to give your energy level a modest boost. When taken together with L-carnitine tartrate, you can better take advantage of the increased fat-burning potential received from carnitine.

Just be sure to include good warm-up exercises in your routine to help you avoid injury. And be sure to take appropriate supplements before your workout.
