Description
What is L-arginine and why is it useful?
L-arginine is a conditionally essential amino acid that occurs naturally in the human body and is an essential building block of proteins. Its most important role in sports nutrition and physiological processes is as a direct biological precursor of the nitric oxide (NO) molecule.
Although our body is able to produce it under normal conditions, during intense physical exertion, hard weight training or endurance training, the body’s need for arginine can increase significantly. Scientific systematic reviews and meta-analyses highlight that targeted L-arginine supplementation – by supporting nitric oxide synthesis – plays a key role in the relaxation of the smooth muscles of the vascular walls (vasodilation). This mechanism allows the blood supply and oxygen and nutrient delivery to muscle tissue under load to remain optimal even in the most critical moments.
Cleanliness without compromise
