L-arginine from a scientific perspective

L-arginine serves in the body as a precursor of nitric oxide – a substance that ensures vasodilation, or the widening of blood vessels. Blood flow enables the transport of oxygen and nutrients to the muscles, which, according to available studies, may have an effect on performance and recovery. [1] [2] 
Some studies examine the combination of L-arginine and citrulline malate and their possible effect on increasing anaerobic performance. [3]

I have to give a low rating because of the packaging. Every 4th capsule is half-empty or completely empty. I haven't seen this with other products, but here it is obvious. Please, check the capsule manufacturing process for this particular product. Thank you. EDIT: The next pack was fine. :)
