The taste of Arginine is somewhat sour. It can be made more palatable by mixing with Black Cherry Concentrate. In Dr. Clark’s opinion (not supported by research) Arginine is helpful as an energizer for those who are quitting coffee. Arginine or L-Arginine is an amino acid that has numerous functions throughout the body. Dietary Arginine is found in plant and animal proteins, such as dairy products, meat, poultry, fish, and nuts. In the human body, Arginine is produced primarily in the kidney and to a lesser extent, in the liver. Arginine helps remove ammonia, a waste product of metabolism, from the body, and is further used to make beneficial compounds such as nitric oxide, creatine, L-glutamate and L-proline. Arginine can also be converted to glucose and glycogen if needed. Arginine may assist the body’s natural tendency to repair itself in cases of wound healing. It may also stimulate the immune function.
