At 6g per scoop, this powder delivers a full dose of **L-Arginine** for blood flow and circulation, landing at the top of the 2–6g range used in nitric oxide and exercise research. Arginine is a direct precursor to nitric oxide, the molecule that relaxes blood vessels to support healthy circulation and exercise pumps. It's listed as the hydrochloride salt, so you're getting roughly 5g of actual arginine — still a working dose.
Worth knowing: oral arginine has variable absorption, since much of it is broken down before reaching your bloodstream. L-citrulline is often considered a more efficient way to raise arginine and nitric oxide levels for that reason. At 6g you have enough to push through that first-pass loss, but this isn't the most efficient nitric oxide precursor you can take.
