Do Nitric Oxide Supplements Truly Help Improve Blood Flow? The Science Revealed:

Nitric oxide is praised for its role in regulating blood flow and supporting heart health, but does it truly live up to the hype?

If you are looking to add nitric oxide into your daily routine, you do well in researching beforehand.

Here you’ll learn the essentials about it to make an educated decision.

Now, does it truly work?

Nitric oxide (also known as “N.O.”) it’s an essential, natural molecule produced by the human body, so it’s present in every one of us.

It has two core functions:

regulating vascular tone, blood flow, and tissue oxygenation;

and controlling the consumption of oxygen by mitochondria. (1)

This shows it’s essential for both healthy blood flow and energy levels, as it regulates our cells’ powerhouse.

So, yes. It works.

However, there’s one issue:

Its availability decreases up to 75% as you age (2), especially in sedentary individuals. (3)

It’s one of the core reasons that make you feel “the weight of your age”.

And to understand why, you just need to know what nitric oxide does for your body:

Benefits of Nitric Oxide Supplementation

Improved blood flow and circulation

Better energy and mood

Superior stamina (even bedroom stamina)

Improved Exercise Performance

Helps maintain healthy blood pressure

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®.

It is scientifically proven to deliver a whopping 230% boost in nitric oxide levels.

In just 3 hours.

It does that by having S7®, Nitrosigine®, and Trans-Resveratrol in its formula.

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)
