Nitric Oxide Keeps Blood Flowing and Keeps You Going*

Nitric oxide is a vital molecule, and the body's signal for healthy circulation. It's continuously made on-demand in every tissue, organ, and system to help blood vessels relax and encourage circulation and blood pressure in the normal range. Nitric oxide levels decline with age, stress, and diet, affecting energy, recovery, and cardiovascular function. Vascanox HP® supports nitric oxide production for up to 24 hours,† supporting endurance, clarity, and long-term cardiovascular health.* Powered by Noxa24®, our patented blend of botanicals features nitrates and polyphenols, helps your body maintain the steady blood flow that every system depends on, in just two capsules, once per day.*†

The Effects

The Effects

Daily life feels easier when circulation is strong. Nitric oxide helps blood vessels relax, allowing oxygen and nutrients to reach the muscles, brain, and heart more efficiently. That means less fatigue climbing stairs, steady focus at work, fast recovery after activity, and deep, more restorative rest.* 

Nitric oxide is important every hour of the day or night, because your body continuously transports nutrients and removes waste whether you are at work, on your daily walk, or even in your sleep. 

In an open-label, published study, a single dose of Vascanox HP increased salivary nitric oxide levels for up to 24 hours.† The unique multi-pathway formula supports nitric oxide production, storage, and delivery for daily vitality and to support long-term cardiovascular resilience.*†

Vascanox HP is more than just a supplement—it’s a scientifically advanced solution for supporting cardiovascular health naturally.

The Science

The Molecule That Keeps You in Motion 

Discovered in Nobel Prize–winning research, nitric oxide is the body’s natural signal for blood vessels to relax, supporting circulation, oxygen delivery, and cardiovascular wellness. But nitric oxide is fleeting, lasting only milliseconds in the body before it disappears. It must be produced continuously, on demand, to keep every muscle, organ, and brain cell supplied with the oxygen and nutrients they need.

Vascanox HP helps sustain this essential process. Our patented bioactive complex, Noxa24, works through multiple pathways—production, storage, and synergistic molecules—to maintain nitric oxide production and stability throughout the day.*  

The result: balanced circulation that fuels stamina, clarity, and cardiovascular health.*
