What is Nitric Oxide (NO)? The Molecule of Life

Nitric oxide (NO) is a gaseous molecule naturally produced by our body, essential for nearly all biological functions. Its discovery was so revolutionary that it earned the 1998 Nobel Prize in Medicine to three American scientists for revealing its role as a vital messenger for the cardiovascular system.

Although technically a free radical, NO is not harmful when physiologically produced; on the contrary, it is the "director" of our vascular and cellular health.

How Nitric Oxide Works: The Role of the Endothelium

NO is produced primarily in the endothelium , the thin tissue lining the inner walls of blood vessels and the heart. It acts as a powerful vasodilator : it relaxes the smooth muscles of the vessels, allowing them to dilate and ensuring optimal blood flow.

However, with aging, stress, smoking, and pollution, the endothelium can become damaged. A compromised endothelium does not produce sufficient NO, triggering problems such as hypertension, atherosclerosis, and reduced tissue oxygenation.

The Health Benefits of Nitric Oxide

1. Cardiovascular System and Microcirculation

NO is the guardian of our arteries. In larger vessels, it suppresses inflammation and inhibits clot formation. In microvessels (capillaries), it promotes angiogenesis (formation of new blood vessels), vital for nourishing every single cell and removing toxins.

2. The "Three Gas" Respiratory Cycle

Besides oxygen and carbon dioxide, NO is the third essential element of respiration. Without nitric oxide accompanying hemoglobin, blood vessels would not open sufficiently to deliver oxygen to the tissues. It is the blood flow mediated by NO, and not just the oxygen content, that determines true cellular oxygenation.

3. Immune and Antiviral Function

NO plays a crucial defense function. Recent research (including that on SARS-CoV-2) has shown that nitric oxide can inhibit viral replication and regulate the immune response, preventing thromboembolic complications and inflammatory "cytokine storms."

4. Cognitive Function and Sexual Health

• Brain: Acts as a messenger between neurons, supporting memory and learning.

• Sexual Health: It is the chemical mediator responsible for erection, as it relaxes the blood vessels necessary for genital blood flow.

How to Increase Nitric Oxide Naturally

As we age (especially after 60), endogenous NO production declines dramatically. Here's how to support your body:

FIR PAD Technology

Using the FIR PAD (Far Infrared Rays) of our 4-Step Therapy is one of the most effective ways to stimulate NO production. FIR rays penetrate tissues and enzymatically activate nitric oxide synthase, increasing NO stores without the need for external substances.

Nutrition and NO: Recommended Foods

You can enhance the benefits of FIR therapy by integrating these nitrate- and antioxidant-rich foods:

• Beets and Green Leafy Vegetables: Rich in nitrates that can be converted to NO.

• Garlic: Activates the enzymes necessary for gas synthesis.

• Citrus Fruits and Pomegranate: Vitamin C and antioxidants protect NO from degradation.

• Dark Chocolate (min. 85%): Cocoa flavanols promote endothelial health.

• Watermelon: Contains citrulline, a direct precursor of nitric oxide.

Lifestyle

• Exercise: Cardiovascular activity mechanically stimulates the endothelium to release NO.

• Nasal Breathing: Did you know that the sinuses produce large amounts of NO? Breathing through your nose directs this gas directly into your lungs, improving oxygenation.

Conclusions

Understanding nitric oxide (NO) means understanding the secret to vascular longevity. From protection against viral infections to heart health, this molecule is our greatest ally in vitality. Through the use of the FIR PAD , a proper diet, and conscious breathing, we can maintain optimal NO levels and protect our bodies at any age.
