Why Do Athletes Use It?*

Some athletes say that arginine helps reduce body fat.

What Do the Advocates Say?*

Arginine is a vasodilator; in other words, it increases blood flow so the heart can pump more blood at a lower level. Theoretically, this translates into improved cardiovascular performance. However, more research needs to be done to see if arginine supplementation can enhance athletes' abilities to perform aerobic activities.

Be aware, when supplementing with individual amino acids, that it is possible to upset the body's total balance of amino acids by taking just one.
