An amino acid the body converts toward nitric oxide production, relevant to blood flow and performance.
L-Citrulline is a naturally occurring amino acid that the body converts into L-arginine and then nitric oxide, a molecule that helps relax and widen blood vessels.
Research has examined L-Citrulline's relationship to nitric oxide production and blood flow, a mechanism relevant to both exercise performance and male performance formulas broadly.
This describes general category research, not a claim about the finished IronPulseX product, which has not been the subject of its own published clinical trial. See the full formula overview or the product overview for more.
