We’ve written previously about the amino acid Carnitine, how it helps spare muscle glycogen (your muscle’s primary fuel source during exercise) and helps to shift muscle metabolism towards fat burning, with the end result of improving exercise performance.
Another cool thing that Carnitine does is to ‘turn on’ testosterone receptors in the muscles. This makes them more efficient at using the hormone, and helps to promote muscle recovery after exercise. Testosterone helps to build and maintain muscle tissue in men and women.
When taken before exercise, it reduces muscle damage from the exercise and speeds up muscle tissue recovery.
This makes L-Carnitine an ideal supplement to take when you are doing a lot of high intensity work with shorter recovery periods in between training.
L-Carnitine is an amino acid that is found naturally in the body. Its perhaps best known for its ability to breakdown fats for energy production. Supplementing with l-carnitine may help your muscles recovery faster, helping you to get more out of your training.
