Nitric Oxide BoostTM — for athletes and bodybuilders
Nitric Oxide Boost is designed to assist your body’s normal production of nitric oxide by supplying three dynamic support factors: L-Arginine, L-Citrulline and CellFuel®.*
L-Arginine is a key nitric oxide precursor*
L-Arginine is a well known amino acid that has been a popular “pump” ingredient with bodybuilders and athletes for years. It is one of the main precursors in the body’s mechanism to produce nitric oxide.* (See Figure 1)


L-Citrulline boosts L-Arginine to support nitric oxide levels*
L-Citrulline is closely related to L-Arginine and it also plays a significant role in the body’s production of nitric oxide. L-Citrulline is able to inhibit arginase, an enzyme that breaks down L-Arginine before it reaches the blood. As a result, taking L-Citrulline with L-Arginine may help more of the ingested L-Arginine pass through your system and get into the bloodstream.*
CellFuel® Antioxidant Blend for ultimate support*
Included in this formula is our expertly crafted organic antioxidant blend. It’s a precise mix of 17 whole food antioxidants packed with nutrient dense fruits and vegetables like organic beet root, organic pomegranate, organic blackberry and more. These powerhouse superfoods work synergistically with the highly-purified amino acids to give you the ultimate nitric oxide boost!*
