The Nitric Oxide Advantage
Support healthy blood pressure, flexible arteries, and powerful blood flow — from the inside out.
In 1998, three scientists won the Nobel Prize for discovering how nitric oxide (NO) signals your blood vessels to relax and open.
That discovery changed everything we know about:
-
Blood pressure
-
Circulation
-
Heart and artery health
-
Even sexual function and physical performance
But here’s the part that affects you:
By around age 50, your body can produce up to 50% less nitric oxide than it did in your 20s and 30s.
Less nitric oxide means:
-
Stiffer blood vessels
-
Harder-to-control blood pressure
-
Heavier, more sluggish circulation
-
More strain on your heart — and on your confidence
Optimized L-Arginine was designed to do something simple but powerful: help your body restore nitric oxide levels naturally so your blood vessels can relax, your blood can flow, and your heart can work with less strain.
Why Nitric Oxide Matters for You
Nitric Oxide is a tiny gas your body makes — but it has a huge job:
- Tells blood vessels to relax and expand so blood can move more easily.
-
Helps maintain healthy blood pressure by supporting flexible, responsive arteries.
-
Supports full-body circulation to your heart, brain, muscles, hands, and feet.
-
Protects cardiovascular health as you age by supporting the lining of your blood vessels (the endothelium).
When NO levels drop with age, you feel it:
-
Climbing stairs feels harder
-
Energy doesn’t last like before
-
“Circulation issues” show up where you least want them
That’s where the right nutrients can make a real difference.
What Makes Optimized L-Arginine Different?
This isn’t just plain arginine. It’s a science-built nitric oxide system designed to:
-
Trigger NO production (L-Arginine)
-
Sustain NO production (L-Citrulline)
-
Support artery health (TMG, CoQ10, Resveratrol, Beets)
Here’s what you’re getting in every serving:
Core Nitric Oxide Drivers
-
L-Arginine (5200 mg) – Direct nitric oxide precursor used by your blood vessels.
-
L-Citrulline (1200 mg) – Recycles L-Arginine and helps maintain NO levels longer.
Heart & Circulation Support
-
Beet Root Extract (500 mg)
-
Red Beet Juice Powder (500 mg) – Plant-based support for blood flow and oxygen delivery.
-
Trimethylglycine (TMG) (100 mg) – Helps lower homocysteine, a compound linked with arterial stiffness and cardiovascular aging.
-
CoQ10 (100 mg) – Supports the energy production your heart muscle needs to work efficiently.
-
Resveratrol (50 mg) – Antioxidant support for healthy aging and blood vessel protection.
Plus, a complete cardiovascular blend of essential vitamins and antioxidants to support your heart, circulation, and energy.
What You May Notice When You Use It Consistently
Everyone is different, but many people report feeling:
-
More steady energy instead of the usual afternoon crash
-
Better stamina for walking, climbing stairs, or daily activities
-
Warmer hands and feet as circulation improves
-
More confidence in the bedroom, thanks to healthier blood flow
-
A general sense that their heart and arteries are being cared for, not ignored
This isn’t a drug and it’s not a magic cure — it’s targeted nutritional support to help your body do what it’s designed to do:
keep blood moving smoothly and efficiently.
Backed by Nobel-Winning Science & Modern Research
Optimized L-Arginine is inspired by the 1998 Nobel Prize in Physiology or Medicine, awarded to Robert F. Furchgott, Louis J. Ignarro, and Ferid Murad for their discoveries of nitric oxide as a signaling molecule in the cardiovascular system.
Our formula is aligned with research showing that:
-
L-Arginine can help reduce blood pressure and slow the progression of atherosclerosis in adults.
-
L-Citrulline works together with L-Arginine to further enhance circulation and exercise performance.
-
TMG (Trimethylglycine) helps lower homocysteine, a known risk factor for heart disease and vascular aging.
When it comes to heart and blood vessel health, the science is clear:
Nitric oxide makes the difference.

Dave D. –
Great product. Mayo recommends 5g of L-Arginine for ED and this one has more than that plus many other ingredients. It works! 🙂

I struggled with circulation issues for years, often experiencing tingling in my feet, especially after sitting for a while. After starting Optimized L-Arginine, I noticed a big difference within just a few weeks. The tingling has significantly decreased and I feel better blood flow in my feet. I can sit comfortably for longer periods without discomfort and my energy levels have improved too. I’m really happy with the results and would recommend it to anyone facing similar issues. I’m 84 years old.
