Moderate effect in increasing the volume of blood flow. It was thought to be a secondary effect of the increase in nitric oxide, but since this property has been ruled out, it is most likely due to another factor;
It lowers blood pressure, but the effect is relatively weak. Studies that combined arginine with citrulline found a more significant effect, especially in individuals with high blood pressure;
Increases growth hormone at rest and after exercise. The effect is short-lived (1-2 hours) and there is no evidence of a general effect on the body;
Increases plasma levels of arginine. Peak levels are increased dramatically, but for longer maintenance of concentrations, intake of L-citrulline is recommended;
Increases adiponectin levels and improves the ratio between adiponectin and leptin, but only in people with impaired glucose tolerance;
It may improve anaerobic endurance, but it has not been found to be due to increased levels of nitric oxide;
It is possible to increase the time to reach fatigue during physical exertion;
It exhibits antioxidant properties and increases levels of the antioxidant superoxide dismutase (SOD). Reduces oxidation processes. It is most pronounced in individuals with impaired glucose tolerance and type II diabetes;
Improves endothelial function;
It may improve fat burning with long-term use, but mostly in people with metabolic diseases and diabetes;
Increases the release of insulin;
Improves pancreatic function and insulin sensitivity, especially in people with metabolic diseases;
Stimulates active weight gain, but mainly in persons with metabolic diseases;
Improves the condition of intermittent claudication. It is a condition in which there is sudden fatigue when walking;
In combination with L-lysine, it suppresses anxiety, which is caused by severe stress;
