Why ProArgi-9+?
One of the primary ingredients in ProArgi-9+ is L-arginine, which was researched by three American scientists who were awarded the Nobel Prize in 1998 for discovering its powerful health benefits in boosting Nitric Oxide levels.
ProArgi-9+ also contains five essential vitamins: Vitamin C, Vitamin D3, Vitamin K2, Vitamin B6 and Vitamin B12. Each plays a vital role in supporting the body’s overall performance.
Our ProArgi-9+ stands out from the crowd, and is listed in the Physicians Desk Reference as the highest quality L-arginine supplement in the world.

"The highest quality L-arginine supplement in the world"
Recognised for its purity and formulation excellence, ProArgi-9+ delivers pharmaceutical‑grade L‑arginine backed by clinical research and trusted by physicians.
That's why it has been listed in the Physicians Desk Reference for over 10 years.

Certified Clean
ProArgi‑9+ is certified clean and listed on the Cologne List®, verifying through independent testing that it’s free from banned or harmful substances.
This certification ensures unmatched purity, safety, and trust, a standard valued by athletes and health professionals alike.


How Nitric Oxide Works
A 60 second explainer on why circulation matters.
Nitric oxide helps your body relax blood vessels, improve circulation, and support how you feel and perform every day.
What Happens As We Age
The body’s natural production of nitric oxide steadily declines with age — meaning the very mechanism that helps blood vessels relax and maintain healthy blood flow becomes less efficient over the years.
This is why we need to help boost our Nitric Oxide levels naturally as we age.
