Nitric Oxide Boosters — A Full Guide on What They Are, Their Benefits, And How to Boost Nitric Oxide Naturally

If you’ve been hearing more and more about nitric oxide boosters lately, you’re not alone. From fitness enthusiasts to people simply wanting better circulation and everyday energy, nitric oxide has become one of the most talked-about wellness topics of the last few years.

But…

What exactly is nitric oxide?
Why should you try to boost it?
Are supplements necessary — or can you increase it naturally?

This guide breaks everything down in plain language so you can understand how nitric oxide works, what benefits it may offer, and the ways to support healthy nitric oxide levels (with or without supplements).

Let’s dive in.

What Is Nitric Oxide? (And Why Your Body Needs It)

Nitric oxide — often shortened to “N.O.” — is a tiny gas molecule your body produces on its own.

But don’t let its size fool you.

N.O. plays a massive role in keeping your cardiovascular system working smoothly.

Its biggest job?

Nitric oxide tells your blood vessels to relax and open.

And when your blood vessels open up, good things happen:

Blood flows more freely
More oxygen reaches your muscles and organs
Circulation improves
Blood pressure stays in a healthy range
Energy and stamina naturally increase

Think of nitric oxide as your body’s built-in “circulation switch.”

When NO levels are high, everything runs more efficiently.

Why Should I Boost Nitric Oxide?

Here’s the catch:
Your body makes less nitric oxide as you age.

Some experts estimate that by the time you hit your 40s, NO production can drop by as much as 50%.

Lower NO levels can contribute to:

Slower circulation
Colder hands and feet
Lower energy
Reduced stamina
Slower recovery
Higher blood pressure
Foggy thinking
Declines in physical performance

This is why working to support nitric oxide production has become so popular — regardless of age.

Benefits of Healthy Nitric Oxide Levels

People boost nitric oxide for all kinds of reasons.

Here are the most commonly reported benefits:

🏃🏻‍♀️ 1. Better Circulation

When blood vessels relax, blood moves easily — especially to your hands, feet, and legs.

💨 2. More Oxygen to Your Cells

Improved blood flow means your cells get the oxygen and nutrients they need to perform well.

⚡ 3. Natural Energy & Stamina

Better circulation + better oxygen delivery = more natural energy throughout the day.

🧠 4. Sharper Brain Function

Your brain uses a ton of oxygen. Boosting NO may help support clarity, focus, and cognitive function.

💪 5. Enhanced Exercise Performance

People often notice easier workouts, faster warmups, and better “muscle pumps.”

❤️ 6. Blood Pressure Support

By helping blood vessels stay flexible, nitric oxide plays a role in maintaining healthy blood pressure.

🔥 7. Healthier Aging

Circulation is the foundation of vitality — supporting N.O. levels may support overall wellness as you get older.

How to Boost Nitric Oxide Naturally

The good news?

You don’t need to be an athlete to support healthy NO levels.
There are plenty of simple, everyday ways to encourage your body to produce more.

1. Eat More Nitrate-Rich Foods

Your body converts natural nitrates into nitric oxide.
Some of the best sources include:

Beets & beetroot juice
Spinach
Arugula
Lettuce
Celery
Cabbage
Swiss chard

Adding any of these to your weekly meals can make a noticeable difference.

2. Add Antioxidant-Rich Fruits & Vegetables

Antioxidants help protect nitric oxide from breaking down prematurely.

Try adding:

Blueberries
Pomegranates
Citrus fruits
Grapes
Dark chocolate (yes!)
Green tea

3. Move Your Body (Even a Little Helps)

Exercise is one of the fastest ways to boost NO production.

You don’t need intense workouts — walking, biking, yoga, gardening, or even light stretching all stimulate nitric oxide release.

4. Get Sunlight / Vitamin D

Sunlight triggers the skin to release nitric oxide into the bloodstream.

Just 10–20 minutes of daylight can help.

5. Reduce Stress

High stress increases free radicals that break down nitric oxide.
Simple stress relievers include:

Deep breathing
Meditation
A warm bath
Quiet time outside
Listening to calming music

6. Consider Nitric Oxide–Boosting Supplements

This is where nitric oxide “boosters” come in.

People turn to supplements when they want:

More reliable day-to-day support
Higher NO production than diet alone can provide
Ingredients shown to improve circulation, stamina, or arterial flexibility

Common ingredients in NO supplements include:

L-Arginine
L-Citrulline
Beet root extract
Resveratrol
Plant polyphenols
Nitrosigine® (a patented, highly bioavailable arginine complex)
S7® (a botanical blend shown to increase NO levels)

Different formulas work in different ways — some act quickly, some work more gently over time, and some combine multiple pathways to support NO throughout the day.

How Supplementation Works

If you are looking to shave some of that weight off your shoulders, here’s how supplementing nitric oxide works:

Most supplements contain L-arginine and L-citrulline. These amino acids are responsible for nitric oxide production in your body. (4)

Still, some studies show no increase in nitric oxide levels by taking L-arginine. (5, 6)

And while L-citrulline does improve nitric oxide bioavailability, it does not boost exercise performance. (7)  

There are also supplements formulated with beetroot, a natural source of nitrate—the “N” in “N.O.”

However, these basic supplements tend to boost N.O. levels only by 21% (8)

So what’s the best way to boost your nitric oxide?

Enter BloodFlow-7® — The Most Efficient Nitric Oxide Boosting Supplement.

Almost every nitric oxide supplement fails to deliver here and there.

So, after intense study, we’ve crafted the ideal formula—doctor-approved by Dr. Darren Farnesi, M.D.

That’s BloodFlow-7®.

Its formula includes S7®, which has been scientifically shown to deliver a whopping 230% boost in nitric oxide levels — in just 3 hours.

BloodFlow-7 combines S7® with Nitrosigine® and Trans-Resveratrol to help you unlock stronger, longer-lasting circulation support.

S7® and Nitrosigine® are ingredients specially formulated to increase nitric oxide bioavailability. (9, 10)

While their names are unusual, S7® is but a plant-based complex, made with 7 nutrient-rich botanicals (hence the name).

And Nitrosigine® is a combination of the amino acid arginine and silicate—a mineral that helps strengthen blood vessels.

These formulations are designed to overcome the limitations of other nitric oxide boosters.

Finally, Trans-Resveratrol on its own has tons of benefits, including:

Improved blood flow
Supports healthy blood pressure
Protects blood vessels, which may reduce the risk of heart disease

Making it a great pair for those other two.

Together, these three form a powerhouse that delivers all the benefits of nitric oxide boosting.  

But we did not stop there.

We also added BioPerine—the black pepper extract that increases the bioavailability of other components by up to 200%. (11)
