L-Citrulline is usually described in the context of the supplement that it compliments, L-Arginine. As a supplement the role of L-Citrulline is relatively simple. L-Citrulline is meant to be converted into L-Arginine by the body. The addition of L-Citrulline allows for there to be a greater amount of unabsorbed L-Arginine once this amino acid passes through the digestive system. L-Citrulline and L-Arginine work together to create synergy. If you are planning on using an L-Citrulline supplement in your diet, you should also be taking an L-Arginine supplement in order to obtain the desired results.
