Arginine and Citrulline are two amino acids that are integral to protein metabolism and utilization, as well as to the maintenance of muscle tissue. Both are key intermediates in the urea cycle, where they participate in the detoxification of ammonia via the production of urea. Arginine that has not been converted to urea enters general circulation where it is distributed to various tissues and metabolized for other uses such as protein synthesis. Scientific studies have shown that supplementing Citrulline along with Arginine helps maintain nitrogen balance better than supplementation with Arginine alone.

About an hour after ingestion I get a sort of rush that settles down 1/2 an hour later. I am not taking this to lose weight or gain muscle, rather to jump-start a sluggish metabolism, and it seems to be working. No after taste, quality product and packaging.
too subtle, but good for muscle soreness for me

I haven't noticed increased energy or pumps, I've also hoped this might have helped my bad peripheral circulation but there were no improvements felt. I did however notice that muscle soreness was significantly reduced after working out on this which is why I give 3 stars.

This supplement has greatly helped my irregular heart beat and angina. Been able to greatly reduce the amount of nitroglycerin i take for controlling those.

Arginine & Citrulline are precursors to nitric oxide. Nitric oxide is a gas naturally found in the body; its function is conveying information between cells. One of its main jobs is increasing blood flow by dilating blood vessels, and that's why it's sometimes given in supplement form to heart patients, orally and intravenously. In at least one study it's been shown to be effective for lowering blood pressure.
