L-Arginine is a safe, versatile amino acid precursor of nitric oxide associated with promoting cardiovascular health, immune support, sexual function, and memory.What Is It?
l-Arginine is a safe, versatile amino acid supporting protein
synthesis and serving as a precursor of nitric oxide.*
Uses For l-Arginine
Cardiovascular Health: In the body, the metabolism of
l-arginine leads to the formation of nitric oxide.
Arginine-derived nitric oxide is an important catalyst
for healthy dilation of blood vessels, circulation, and
blood flow. In a prospective, double-blind trial, l-arginine
supplementation supported healthy endothelial function
in blood vessels of male volunteers. In other studies,
l-arginine promoted healthy platelet function and
enhanced exercise tolerance. Additional trials indicate that
l-arginine may support healthy lipid metabolism and
moderate lipid peroxidation, enhancing its cardiovascular
Support For Immune Function And Healthy Tissues:
Arginine has demonstrated immuno-stimulatory activity
and may promote the utilization of nitric oxide by
scavenger cells for defense mechanisms. Enhancement of
immune messenger compounds has also been observed
in several studies with l-arginine. In a study involving
elderly individuals, l-arginine facilitated healthy tissue
recovery, accelerated tissue repair and supported immune
Male Sexual Function: In men with low urinary nitric
oxide values, l-arginine may support healthy sexual
performance. Some but not all research involving
l-arginine supplementation for sperm motility have produced
Growth Hormone Support: Arginine plays a role in
the synthesis of hormones such as insulin and growth
hormone, and has demonstrated the potential to support
glucose metabolism and growth hormone production
Memory: Nitric oxide is also a mediator of
neurotransmission in the brain, supporting memory
under the circumstances of reduced intracellular
What Is The Source?
l-Arginine HCl is derived from the fermentation of soy and
other vegetable sources and is ultra-filtered and highly
Are There Any Potential Side Effects Or
If pregnant or lactating, consult your physician before
taking this product. Because of its effect on nitric oxide
production, l-arginine is theoretically best avoided by
individuals with migraines, depression, autoimmune
disorders, and kidney or liver disease. Arginine is
contraindicated for individuals with the herpes virus.
