L-Arginine is a potent amino acid that occurs naturally in the body. It works to produce nitric oxide (N.O.), the “miracle molecule” that helps relax blood vessels (known as vasodilation) and improve circulation, which leads to stronger blood flow.

When it comes to athletic performance, stronger blood flow means better pumps when lifting weights, and thus an improved ability to build muscle. For sexual performance, enhanced blood flow means more excitement and more support when and where you need it most.

A fully substantiated 3,000mg of L-arginine in each serving, along with BioPerine® and selenium for optimal absorption, means there is no doubt that you are getting the dose scientifically shown to produce powerful results time after time.

All of the Force Factor® Fundamentals formulas were designed to stack together, as well as with any other supplement in our full line of premium performance nutrition products.
