Testosterone Booster With Nitric Oxide

Testosterone Booster With Nitric Oxide

When you are looking for a natural T booster you look through the ingredients list, some may contain nitric oxide.

You may wonder why, because, nitric oxide is commonly found in many pre workout supplements, either by itself as it’s chemical compound or via another ingredient such as beet which can increase the amount of nitric oxide in the blood.

LAST UPDATED: March 2019 by Ben.

What is nitric oxide and why is it important?

Nitric oxide has been thrown in to the public eyes fairly recently and not for a good reason.

It was the center of the ‘diesel gate’ scandal involving VW.

Volkswagen used software to trick the EPA emissions tests in to ‘reading’ that the cars were releasing less nitric oxide than they do in normal driving conditions.

So, in essence this may seems a little confusing.

Why is there so much hype and news surrounding a chemical compound that is seemingly dangerous to our health and the environment?

Yet, there are supplements feeding our body with this very same chemical compound?


You see, nitric oxide in very high concentrations is actually a toxic gas.

However, in animals (this includes humans) nitric oxide is a molecule that acts as a messenger.

This molecule transmits signals throughout the cardiovascular, nervous and immune systems.

It possesses a free radical, and, in turn this makes it able to react much better than other signalling molecules.

It is also of a small size, a result of this diminutive nature means that it is able to diffuse through cell membranes and the walls.

This means it can operate and perform a wide number of signalling functions throughout multiple bodily systems.

Vessel relaxation

Nitric oxides’ real punch though, in terms of physical performance, is that it causes muscle cells to relax.

In turn allows the blood vessels to open up and become dilated.

The benefit of this dilation is that blood can flow much more easily and also decreases blood pressure.

Nitric oxide also helps improve the functioning of digestion, memory and even vision.

Besides these points, it also plays a crucial role killing bacteria, tumor cells and even help treat angina which is caused by an inadequate supply of blood to the heart.

It is this vessel dilation that helps athletic performance by delivering more nutrients and oxygen to the organs and muscles.


This also has a sexual benefit…

Nitric oxides’ ability to relax the smooth muscle cells allows the blood to flow more easily which is part of the penis erection process. [1]

So, as you can see, as potentially dangerous too much nitric oxide can be, it is vital in much lower concentrations to healthy bodily function.

So why is nitric oxide not included in many testosterone boosters?

Well, nitric oxide production is actually stimulated by testosterone. [2]

There’s evidence to suggest that nitric oxide is actually synthesized in the testes of mammals.

Nitric oxide itself is mostly localized in the Leydig cells.

However, studies in vertebrates suggest that nitric oxide and D-aspartic acid act as opposing regulators of hormone production. [3]

Therefore, not only would including nitric oxide to a natural testosterone booster not be necessary if the test booster is actually effective at stimulating more testosterone.

However, actually supplementing more nitric oxide to your body could potentially be harmful to natural testosterone production. [4]

Why would nitric oxide be added to test booster supplements?

What we have seen a lot of are supplements actually trying to mimic the effects of increased testosterone rather than trying to include the correct and proven ingredients to stimulate it.

This happens more that you may think.

These products are merely trying to make you think that they are having a positive effect on testosterone levels.

To do this, they will include ingredients that can help stimulate fat loss such as green tea or even increase energy such as caffeine.

However, it is important to remember these products are not stimulating testosterone. Merely copying what it can do.


Really, they should be called testosterone effect boosters.

T boosting supplements that contain nitric oxide are not only having a harmful effect on natural testosterone production but not actually helping raise test levels at all.

So, it is better for you to avoid using any supplements which claim to increase natural T levels that also include nitric oxide.

These will not help.

Increasing your natural levels of testosterone will help with libido and erection problems and will produce its own levels of nitric oxide in the correct concentrations.


If you are looking to increase testosterone nitric oxide is not a nutrient to look for.

After all, it may have a reversed effect.

Additionally, just because it may help improve erections that does not necessarily equal increased levels of testosterone.

In some cases, it may be considered that it is included in some testosterone booster supplements to merely mimic the effects of increased levels of testosterone.
