Most people have never heard of Nitric Oxide (NO). In fact, the other day as I was talking with a friend, they made the mistake of thinking I was referring to Nitrous Oxide (ie: laughing gas), which dentists use to knock us out for surgery….and no, this is different and much more incredible. 

Nitric Oxide is a tiny molecule, produced naturally in your body, and has been coined the “miracle molecule” by scientists. In fact, the discovery of Nitric Oxide as a signaling molecule in the cardiovascular system was so groundbreaking that it earned the 1998 Nobel Prize in Medicine.

Not the Nobel Peace Prize, but the Medicine one (although it possibly could be awarded for all, because it brings peace to one’s life daily…see what I did there?)

So why does Nitric Oxide matter to you? Because it plays a role in nearly every aspect of your health: from the way your heart pumps, to how much energy you feel when you wake up in the morning, to the clarity of your thoughts. Can it actually do all of these things? Absolutely, and more.

Let’s explore why Nitric Oxide is considered your body’s hidden superpower, and how you can support it.

What is Nitric Oxide?

Time for a quick science lesson, yet have no fear, this took me a while to even learn how to describe this correctly, and it’s about to blow your mind:

Nitric Oxide is a simple gas molecule made up of one nitrogen atom and one oxygen atom (NO). Despite its simplicity, it’s a master regulator inside your body. It tells your blood vessels when to relax and expand, allowing oxygen and nutrients to travel more efficiently to your muscles, brain, and organs.

Think of Nitric Oxide as the body’s “traffic controller.” When blood flow is smooth, your cells thrive. When Nitric Oxide is lacking, traffic jams appear - causing strain on your heart, fatigue in your muscles, and even cloudiness in your mind.

Still with me? Below I describe why this knowledge base is essential for you to understand the science for your own health journey and adjustment. 

Why Nitric Oxide Declines With Age

Here’s the challenge: your body’s ability to produce Nitric Oxide drops dramatically as you age. Research shows that by the time you reach 40, you may only be producing half the Nitric Oxide you did in your 20s. By 60, your levels can be almost negligible.

Ever wonder why you “feel older” as you age? It’s not just time, it is everything happening all around us! 

Other lifestyle factors also deplete NO levels, including:

• Processed foods and poor diet
  

• Sedentary lifestyle
  

• Stress and poor sleep
  

• Certain medications
  

The result? Less energy, higher blood pressure, slower recovery, and a greater risk of cardiovascular issues. 

“Lions and tigers and bears - Oh my!”

The Many Roles of Nitric Oxide

What makes Nitric Oxide a “miracle” is its versatility. It doesn’t just impact heart health, it affects almost every system in your body.

• Heart & Circulation: Keeps blood vessels flexible, supporting healthy blood pressure and blood flow.
  
  

• Brain Function: Enhances oxygen delivery to the brain, supporting memory, focus, and clarity.
  
  

• Exercise & Recovery: Increases endurance, improves oxygen efficiency, and accelerates muscle repair.
  
  

• Immune Defense: Helps immune cells respond quickly to threats.
  
  

• Energy & Vitality: Fuels your cells with the oxygen they need to perform.
  
  

When your body has abundant Nitric Oxide, you feel it: more energy, sharper focus, stronger workouts, and overall resilience. And, as an aside: Fellas, even your wife will notice some great things happening when it matters most (wink, wink), and, you’re welcome. 

Natural Ways to Boost Nitric Oxide

Fortunately, your body isn’t stuck with declining Nitric Oxide levels—you can support and restore production.

1. Eat NO-rich foods: Beets, spinach, arugula, and leafy greens are packed with nitrates that convert to Nitric Oxide.
   

2. Get moving: Exercise stimulates endothelial cells (the lining of your blood vessels) to produce NO.
   

3. Breathe through your nose: Believe it or not, nasal breathing produces more Nitric Oxide than mouth breathing (hard to do while sprinting, but try to adjust your breathing to nostrils when possible).
   

4. Supplement wisely: Some people choose high-quality supplements designed to support Nitric Oxide pathways.

John Hewlett: From Skeptic to Advocate

When it comes to Nitric Oxide, one name has become synonymous with education and advocacy: John Hewlett, Visionary and Founder of Cardio Miracle.

Years ago, John faced his own health challenges. Skeptical of supplements and having been previously injured by incompetent medical care, he began researching the science of Nitric Oxide. What he discovered changed not just his health, but his mission. He committed himself to learning everything possible about NO: interviewing experts, studying research, and eventually developing a comprehensive way to support the body’s natural production.

John has since become a trusted voice, appearing on countless podcasts and interviews to explain the role of Nitric Oxide in modern health. His message is clear:

“You can’t outsource your health. Nitric Oxide is something your body must generate - and it can change everything.” 

- John Hewlett, Founder & Formulator of Cardio Miracle, the World’s #1 Nitric Oxide Formula

Through these conversations, he’s not just sharing a product, he’s leading a movement to help people understand a molecule that could transform their health.

Why This Matters Now

Chronic disease, fatigue, and stress are at record highs. Yet the solution isn’t always more medication or another fad diet. Sometimes, it’s about restoring what your body already knows how to do: make Nitric Oxide.

By learning about this “miracle molecule,” you gain a tool that empowers you to take charge of your health. It’s not about quick fixes - it’s about giving your body the ability to function the way it was designed.

What’s My Miracle?

Nitric Oxide may be invisible, but its effects are life-changing and have been a miracle in the lives of those affected positively by it. From your heart to your brain, from your workouts to your sleep, it’s the silent force keeping you alive and thriving.

Personally, I have seen the miracle of rapid recovery with NO therapy, following a violent knee surgery where I recovered in one-third of the time, as well as greater clarity in my every day work, writing, speaking, and especially when working out every day. Faster recovery, more power, it brings happiness and peace to my life. Can Cardio Miracle do all of this? It has for me and it can for you, too. 

Your body was built to create miracles. Nitric Oxide is one of them. What is keeping you from living your miracle today?
