NO2 Factor Review – Is This Product for You?

What Is NO2 Factor?

NO2 Factor is a weight loss and strength-building supplement that is designed to boost energy and blood flow, accelerate fat loss, and support general energy. This supplement functions similarly to many other nitric oxide boosters. The central ingredient is L-Arginine, along with two other forms of arginine.

A Nobel-Prize winning research study conducted in the 1990s found that L-Arginine has remarkable properties when it comes to building muscle and increasing energy and endurance. L-Arginine is connected to nitric oxide, as it is its precursor. Many nitric oxide boosters are essentially L-Arginine supplements. L-Arginine is one of the essential amino acids, and when you supplement with enough of it, you can make sure that you have the maximum level of nitric oxide you need.

Nitric oxide increases blood flow to muscles. This supplies oxygen and nutrients to working muscles, which is excellent for endurance and strength exercises. When you lift or perform endurance exercise, muscle fatigue causes lactic acid buildup, which leads to the burning sensation you feel in those last few reps or last few miles. When blood flow to muscles is increased, it delays fatigue by supplying muscles with the fuel they need to work longer and harder. And when you can crank out those last few reps or run just a little longer, burning fat and building muscle gets easier.



NO2 Factor is manufactured by a company of the same name. The company is located in Atlanta, Georgia, and all NO2 Factor is made in the United States. Contact info for the manufacturer can be found on the NO2 Factor web site.


How NO2 Factor Works?

As mentioned earlier, NO2 Factor is billed as a nitric oxide booster, but it actually relies on a complex set of ingredients to help you address your fitness goals using one supplement.

This supplement has a variety of ingredients, which can be grouped based on intended effect. Of course, L-Arginine and other forms of Arginine are present to boost blood flow to muscles in order to reduce fatigue, support muscular growth, and help speed the process of muscle growth and recovery. L-Citrulline is also a key ingredient, as it helps to clear waste products from the muscles, thus reducing the burning sensation you feel due to lactic acid buildup. IT works in concert with L-Arginine – as L-Arginine boosts the flow of blood to muscles, L-Citrulline speeds waste product removal. The end result is that you can work out longer and lift harder while dealing with less fatigue.

A collection of vitamins is present as well – this is to help ensure that your immune system stays healthy and that you have natural energy. The main vitamins included are the B vitamins, which help support a healthy metabolism and immune system, and Vitamin D3, which not only supports the immune system but also aids in the absorption of other nutrients, including calcium and iron. When your body is in optimum health, it makes it much easier to put on muscle and successfully get through more challenging workouts.

NO2 Factor also contains a host of natural ingredients derived from plant extracts. Some of these are backed by scientific research. Others are supported by champion bodybuilders. Many of these herbal supplements are designed to increase metabolic rate so you burn fat faster and have more energy.

NO2 Factor stands out as an all-around supplement, as it combines a collection of supplements that many fitness enthusiasts buy separately. This saves time and money, and it also simplifies the day-to-day supplement routine. Best of all, NO2 Factor, like all nitric oxide boosters, can also have a stimulant effect, making it a good choice for a pre-workout supplement. Because it’s designed to support metabolism and help increase muscle size, this supplement can be the only supplement that you take.


Ingredients of NO2 Factor

NO2 Factor has several ingredients that are sourced from a variety of places. Here are the included ingredients and how they work:


L-Arginine is the crown jewel of this supplement, as t was the subject of research that won the Nobel Prize in Medicine. The research confirmed what athletes who have taken this necessary amino acid in supplement form already knew – that L-Arginine makes it so you can lift more weight for longer periods of time without getting fatigued. The study confirmed that there’s science behind the claims L-Arginine users were making – by increasing blood flow to skeletal muscles and relaxing smooth muscles, this supplement delivers more oxygen and more nutrients to muscles. The increased oxygen delivery makes it ideal for endurance sports and strength training – more oxygen equals less fatigue, which makes it easier to run that last mile or to do just one more rep.


This supplement works similarly to L-Arginine. A 2011 study published in the International Journal of Sports Nutrition, Exercise, and Metabolism found that athletes who supplemented with Arginine-Alphaketoglutarate for seven days had an increased plasma concentration of L-Arginine.

Arginine Akic

Like the two other Arginine variants listed above, Arginine Akic promotes higher levels of nitric oxide in the blood. Because its effects are short term, supplementing with Arginine Akic prior to working out is the best way to take it.

L-Citrulline Malate

This supplement is actually found naturally in watermelons and apples, but you would have to eat a ridiculous amount of both to get the desired effects. L-Citrulline Malate is an amino acid paired with an apple derivative, and it works similarly to L-Arginine. Like L-Arginine, L-Citrulline Malate promotes nitric oxide in the body, thus leading to the aforementioned benefits of L-Citrulline Malate. But perhaps the most useful part of supplementing with L-Citrulline Malate is the fact that it helps lear muscular waste products.

It makes sense – when you boost blood flow by adding L-Arginine, muscles will produce more waste products – ammonia and lactic acid – as a result of having access to more blood. L-Citrulline Malate works to clear waste products, thus delaying the onset of fatigue. Some studies suggest that you can enhance the effects of L-Arginine when you take L-Citrulline Malate as well.

In addition, some studies have found that supplementing with L-Citrulline Malate can boost levels of adenosine triphosphate, or ATP, in the muscles. ATP is a source of energy to working cells, and when you have more ATP, your muscles have enough power to lift more and work harder.

Vitamin D3

We all get Vitamin D from sunlight, but supplementing with it doesn’t hurt, especially if you aren’t in the sun a lot or if it’s during the colder months, when you have less skin exposed and can’t absorb as much as you would want.

Vitamin D3 helps to absorb calcium, iron, and a variety of other nutrients. It supports bone strength, which is especially necessary if you do a lot of high-impact exercise. When your bones are healthy and strong, you’ll be less likely to succumb to training-induced fractures.

Vitamin B6

You’ve probably seen B-complex vitamin formulations marketed as energy boosters, and Vitamin B6 is almost always there. Many people have a mild B6 deficiency. Making sure you get enough B6 helps to support a healthy circulatory system and general health. This also often leads to more energy, as your body is in better health.

Vitamin B12

Vitamin B12 is a panacea of the vitamin world. It supports healthy energy, as it boosts mood, can help people with depression, can improve immune function, and more. It is used as a supplement to help manage a host of diseases and other health problems. You can find it in many B-complex supplements. Making sure you’ve taken in enough Vitamin B12 can go a long way towards supporting a better workout.


Fenugreek can help regulate blood sugar and stimulate insulin, making it a good choice for people who want to drop fat. It is also an energy booster that can be used to help treat a variety of health problems.

Tribulus Terrestris

This plant is an invasive species in America, but it has been used for centuries in Indian and Chinese natural medicine. Champion bodybuilder Jeffrey Petermann has famously vouched for its effectiveness when it comes to building muscle. However, research has not definitively supported its effectiveness in this arena.

Eurycoma Longfolia

This plant has become so popular in Malaysia that it is a protected species there. It can help burn fat, build muscle, and increase athletic performance, and it does so completely naturally. Some research suggests that it may work as a testosterone booster, though this is not yet certain.

Raspberry Ketone

If you have any experience with diet pills, you’ve probably come across Raspberry Ketones at least once. This extract from raspberries is purported to speed metabolism and help increase fat loss. There is some scientific evidence behind it, and plenty of people swear by it, but research has not determined that it is a guaranteed way to lose weight.



This supplement has many advantages, one of which is the fact that it can be used as an all-in-one supplement. It functions as a pre-workout pill, it can support general health and increased energy, and it can also support muscle growth, harder workouts, decreased recovery time, and fat loss.

By combining popular supplements into one, NO2 Factor simplifies the supplementation routine. All ingredients are natural, it’s made in the United States, and it comes with a satisfaction guarantee, making it a feasible choice for anyone wanting to try it before committing.



NO2 Factor has yet to receive any certificates or awards. However, it is based on Nobel Prize winning research. It has been featured in Maxim, Men’s Journal, Fitness Rx, Muscular Development, Muscle and Fitness, Men’s Fitness, Musclemag, and more.



If you aren’t sure about NO2 Factor, reading these testimonials from satisfied customers can help:

Dan, 38, Lansing, MI:

As an older guy, I can really feel my metabolism slowing down every day. Or I could feel it slowing down before I started taking NO2 Factor. This stuff is awesome. Admittedly, I haven’t been on it long enough to see the muscle-building benefits, but the energy boost was almost immediate. Great, great stuff. I’ll write another review once I see all the results – I just had to get this out there.

Jackie, 22, Falls Church, VA:

Because I’m not a dude, I try to stay away from testosterone boosters, but I needed something to help with my workouts. I was fatigued all the time, and then I started taking a B12 supplement. It helped some, but then I tried this. It’s been six months and I’ve really improved. You can see it in my muscle tone and in the fact that I have so much energy. I can work out harder than before. I can’t believe I didn’t even know about L-Arginine until I tried it. It really helps out with endurance exercise, too – I do a group bike ride every so often and usually get wiped out by mile 30. Not anymore! I recently went on a 50-mile ride on my day off and had energy to spare, plus a great average speed. Hoping I’ll improve even more.

Rob, 32, Yuma, AZ:

I’ve been supplement-hopping for a long time, and after blowing just about a thousand dollars on a bunch of auto-ship scams that don’t even work, I tried this. I only did it because I overheard some guys at the gym talking about it and how it helped them really get cut. Plus, it wasn’t even that expensive, so I had to give it a shot. And I’m so glad I did. I look good and feel great. Glad I went with the six-month plan because it saved me a whole lot of money. I’m on month five and I’m definitely buying again. I know that there’s no fitness magic bullet, but this comes closer than anything i’ve ever taken. I didn’t have to modify my training routine or my diet (they were both healthy, though) to get this to work. It’s just a nice addition that helps you get the muscle you want even faster.

Dylan, 25, Topeka, KS:

I’m not your average bodybuilding supplement buyer. When I started on this a year ago, I was pretty fat and felt tired a lot. I’d been overweight since I was 13 and just hadn’t had the will to do anything about it. And I stayed fat all through college. When I started on NO2 Factor, I could barely run a mile. Now, though, I’ve lost 45 pounds and I actually look like I belong at the gym. It’s a good feeling. I’m not the fat kid any more, and I keep getting stronger. NO2 Factor is a lifesaver.
