Read MoreFrequently Asked Questions
What is Nitric Oxide, and why is it important?
Nitric Oxide (N.O.) is a molecule naturally produced by the body that plays a critical role in cardiovascular health, blood circulation, and overall well-being. It helps improve oxygen and nutrient delivery to cells, supports healthy blood pressure, and enhances cognitive function. However, as we age, the body's natural production of Nitric Oxide decreases, making supplementation essential.
How do NO2U products help boost Nitric Oxide levels?
NO2U products are scientifically formulated to restore and enhance Nitric Oxide production in the body. Developed by Dr. Nathan S. Bryan, a leading expert in Nitric Oxide research, these supplements are designed to support cardiovascular health, improve circulation, and provide antioxidant benefits.
What products does NO2U offer?
NO2U offers a range of Nitric Oxide supplements, including:
- NO2U Nitric Oxide Lozenges: Convenient lozenges to boost N.O. levels.
- N.O.Beetz: A fermented oxalate free beet-based supplement for enhanced Nitric Oxide production.
- Power & Performance Stack: A combination pack for comprehensive support.
Who is Dr. Nathan S. Bryan?
Dr. Nathan S. Bryan is a world-renowned biomedical scientist with over 25 years of expertise in Nitric Oxide research. He has collaborated with Nobel Laureates, holds numerous U.S. and international patents, and has published over 100 peer-reviewed articles.

What are the benefits of Nitric Oxide supplementation?
Supplementing with Nitric Oxide can:
- Improve cardiovascular health.
- Enhance blood circulation and oxygen delivery.
- Support healthy blood pressure levels.
- Boost cognitive function and memory.
- Provide antioxidant support.
Why does Nitric Oxide production decrease with age?
As we age, lifestyle factors and natural biological changes reduce the body's ability to produce Nitric Oxide. This decline can lead to issues like poor circulation, high blood pressure, and reduced cognitive function. Supplementation helps restore these levels.
