Found in watermelon, L-Citrulline is converted to L-Arginine in the body which increases nitric oxide production. Compared to supplementing L-Arginine, SwissRX™ Nitric Oxide increases nitric oxide levels longer, increasing blood flow to working muscles so you can push harder and achieve more from your training.

Grape Seed Extract activates your body's nitric oxide production through endothelial nitric oxide synthase (eNOS), further increasing nitric oxide levels in your blood. By promoting endogenous nitric oxide production through multiple pathways, your body maintains higher levels of nitric oxide in the blood than comparable single-ingredient nitric oxide boosters on the market.

Quercetin, a powerful flavonoid, can systemically reduce blood pressure by relaxing the smooth muscle in blood vessels. This allows your body to better circulate nutrients and oxygen to working muscles. Further, as a powerful antioxidant, quercetin works to scavenge free radicals associated with high intensity exercise to improve your recovery between workouts.
