L-Arginine is the direct precursor to the powerful vasodilator nitric oxide*. Alpha-ketoglutarate (AKG) promotes Kreb’s Cycle energy production.* Together they deliver a potent one-two punch to amplify the body’s production of nitric oxide.*

L-Citrulline helps the body use NO to its fullest potential. SPORTS ILLUSTRATED™ Nutrition’s Nitric Oxide formula opens the channels for extreme energy and physical performance.*

L-Citrulline helps the body use NO to its fullest potential.* As a precursor to L-arginine production, this amino acid has its own value as an amino acid.* Evidence suggests L-citrulline may be involved in the formation of certain proteins in addition to its direct and indirect effects on vasodilation and NO synthesis.*

Primarily known for its stomach-soothing qualities, ginger is much more. It’s a well-recognized herb for testosterone support and stress management.* Evidence suggests that ginger compounds may work through a mechanism of action that involves the stimulation of NO production.*

Garlic is widely revered as a cardioprotective food.* It turns out that among its other amazing benefits, garlic contains compounds known to activate nitric oxide synthase, the enzyme that aids in the arginine-to-NO conversion.*
