The ingredients of NO2 Max are formulated to ensure that you are receiving optimal benefits from the product. You can see a list of ingredients and their uses at, or continue reading our in-depth ingredients list. 

Active Ingredients

There are only 2 marketed active ingredients in NO2 Max. 

Calcium is taught to use as children to help with bone strength and growth. However, it also has its benefits when it comes to weight loss. 

With a healthy diet and an exercise routine, calcium helps your body burn off fat quicker, and thus making your muscles have more blood flow. 

Blood flow to your muscles is important when you are trying to build them, as it gives you more stamina and provides more nutrients for the muscles to have the ability to grow larger. It also increases your overall energy, so you will not feel sluggish during or after your workout. 

L-Arginine Alpha-Ketoglutarate has been proven to increase the blood flow in the muscles. It also increases the NO2 that is going to your muscles. 

NO2 is important for muscle growth; it promotes fat loss and allows for your muscles to be strong and to continue growing. 

The promotion of blood flow is also important for protein synthesis. Without protein synthesis (the breakdown of proteins), you will not be able to grow or strengthen your muscles. 

Inactive Ingredients

Inactive ingredients are often used as fillers in products. However, the inactive ingredients in NO2 are used to benefit your body, not a filler for the product. 

Microcrystalline cellulose has been proven to increase strength and energy. It helps you work out for longer and ensure that you are not exhausted before your workout is over.  

  • Crospovidone

Crospovidone is an inactive ingredient found in most pharmaceutical drugs and is used as a booster for your product to be absorbed faster. This way, you will receive benefits faster than without the use of crospovidone.  

Stearic acid has been proven to aid in fat loss and lean muscle gain. It has also shown to prevent cancer.

Vegetable stearate is a form of stearic acid. It is used as a binding agent, but since it is a variant of stearic acid, it also aids in fat loss and the gain of lean muscle. It is used in many foods as well as pharmaceutical medicines.

Silica is used as an anticaking agent and to help the product be more soluble in your body. However, it is also a key element in our body, including muscles, the liver, kidneys. 

Our bodies will often weaken our internal organs when working out, depleting them of water, nutrients, and oxygen. Silica will help rejuvenate our organs so we can continue working out and gain muscle mass.  

Hydroxypropyl methylcellulose (HPMC) is found in many foods. It is used in NO2 Max to prevent weight gain and to stop fat production around the liver, which can cause health issues. 

With a healthy diet and exercise routine, you will be able to see your fat work off faster and see your muscles grow bigger.

Propylene glycol is used in many foods as an anti-freeze ingredient and in pharmaceutical drugs to help the liver. When working out, your body produces lactic acid. 

Propylene glycol aids the liver in producing lactic acid, so you will experience less cramps and have more stamina during your workout. 

However, propylene glycol has also shown to promote kidney failure if you ingest more than the recommended dose from the World Health Organization and can have effects similar to those of intoxication. It is important to never take more than the recommended dose.  

Triacetin has been known to aid in cell growth. It means that it can help your muscle mass growth. It has not been proven to be toxic to any animal nor humans. 

However, it has shown signs of aiding in the growth of noncancerous cells. It only happens in mass amounts, which is not found in NO2 Max.

How Does NO2 Max Work?

As seen, NO2 Max has ingredients that support muscle growth and the promotion of the human growth hormone production. 

Even the inactive ingredients have their benefits, such as promoting liver and kidney function, muscle growth, and ensuring nutrients in the blood are being delivered to your muscle tissue. 

The ingredients in NO2 Max promote the production of NO2 in your blood, which is important when growing your muscles. 

Blood vessels are widened, allowing the optimal flow of blood and nutrients to the muscles. It allows for you to have higher stamina and energy when working out.

NO2 Max does not use any steroids in their product. It ensures that their product is not only safe to use, but also legal. There is also no injections and no doctor referral required to use this product. 

All the ingredients are scientifically backed, meaning you can trust using this product. Although some ingredients can be toxic in mass amounts, mass amounts are not found in NO2 Max. Never exceed more than the recommended dosage.  

Benefits of Using NO2 Max 


By using NO2 Max, you will have higher strength. The increase in blood flow to your muscles will allow you to work out longer and harder, so you will increase muscle growth and strength. Some of the ingredients also promote body strength on its own without the use of working out. 


The increase in blood flow through your body also allows an increase in energy. You will be able to work out longer and not feel drained afterward. NO2 Max will also increase the amount of NO2, which provides oxygen for your body, so you will not feel as tired during or after workouts.


NO2 Max allows your muscles to grow and increase your stamina. It ensures that you will be able to progress further in your workouts and obtain higher muscle mass gains.  


With an increase in stamina and energy, you will see your performance improve. You will be able to work out longer and harder without the repercussions of working your body too hard in the gym. 

Fat loss

Many ingredients in NO2 Max promote fat loss in the body. It will allow you to not only notice your muscle mass easier but also improve your health. 

Some of the ingredients also promote the loss of fat cells around the liver, further improving your health and reducing the risk of future health complications. 

Muscle gain

Ingredients in NO2 Max promote not only NO2 production in the body but also the production of human growth hormone. Both of these are essential in building muscle mass and will allow you to see faster results when working out. 

Side Effects of NO2 Max 

Although NO2 Max does not have any side effects on its own, some of its ingredients do when taken in mass amounts. 

Lowered Blood Pressure

Athletes and bodybuilders typically have lower blood pressure than the average person. It is important to monitor your blood pressure to ensure that your body is getting the needed amount of blood flow and that you will not blackout.

Trouble Breathing

If you have asthma or have issues breathing, you should be cautious when using this product. 

NO2 is derived from oxygen, so it does take the oxygen we breathe in to be produced in the body and delivered to muscle tissue. It is not a common effect of NO2 Max, but you should be aware of the possibility.

Toxicity Warning

When taking mass amounts of NO2 Max, you can receive a toxic amount of its ingredients. This is why it is crucial to never use more than the recommended dose of NO2 Max. 

There have also been studies showing that overproduction of NO2 can be toxic to the body, but with the recommended dose of NO2 Max, you will not experience this.

As with any product, it is important to monitor any rising effects in your body. Although users do not widely see the side effects of NO2 Max, you should be aware of them before using the product.
