An amino acid the body uses to produce nitric oxide, supporting relaxed blood vessels and healthy circulation.
L-Arginine is a semi-essential amino acid — the body produces some on its own, but dietary or supplemental intake can add to that supply.
It's the formula's core circulation ingredient, supplying the body's direct precursor for nitric oxide production.
Nitric oxide is well studied for its role in helping blood vessels relax and widen, supporting healthy circulation.
This describes general research on L-Arginine itself, not the finished MaxForce product, which hasn't been the subject of its own clinical trial. See the full ingredients list or the formula overview for more.
