What Is L-Carnitine Tartrate?

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 tartrate is commonly used by athletes looking to burn fat and build muscle. The addition of tartrate to the carnitine molecule speeds absorption so it can become available sooner, and clinical evidence indicates it promotes muscle recovery and muscle growth.

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.

Do Cardio for Peak Benefits

In order to achieve peak benefits from taking L-carnitine tartrate, it is important to engage in fat burning aerobic exercises. The best cardio exercises are the kind that help you quickly reach your peak effective heart rate and keep it there as long as possible. 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.

One last thing before I go. When you want to reward yourself for all of your hard work, indulge yourself with a professional massage therapy session. Massage isn’t just a luxurious indulgence—it will also speed your recovery, helping you pursue your goals and enjoy yourself at the same time.
