How Does L-Arginine Work?
L-arginine has several different functions within the cells of the human body, many of which are related to nitric oxide production. L-arginine is used in the body to make nitric oxide, an important substance that causes the blood vessels to relax. L-arginine may also have antioxidant properties. There is some research that suggests that L-arginine may inhibit angiotensin-converting enzymes (ACE), much like ACE inhibitor
blood pressure medications. L-arginine may also stimulate the production of certain hormones, such as growth hormones, prolactin, and insulin.
These are just a few of the ways that researchers think L-arginine may work for a variety of conditions. As more studies are done, more information will become available about how L-arginine works.
L-Arginine Use in Children
L-arginine is probably safe for children when taken at reasonable doses under the supervision of a healthcare provider. Do not give your child L-arginine supplements without the approval of your child's healthcare provider.
