The 5 Best Nitric Oxide Supplements

Researchers have shown that boosting Nitric Oxide can have a wide variety of benefits. One of the most prominent reasons for athletes to boost NO is because it helps enhance exercise performance.

When you increase NO, your blood vessels widen, and more blood and oxygen can reach your muscles. This means they could handle more workload, and you'll experience much better muscle pumps.

Besides the boost in exercise performance and capacity, increased NO levels can also help erectile dysfunction and reduce high blood pressure.

To successfully boost nitric oxide, you're going to need potent ingredients to help you achieve this. Many ingredients could help with this increasing this process; we're going to show you 5 of the most effective ones.


1. L-Citrulline

One of the most effective ingredients for boosting nitric oxide levels is L-Citrulline. L-Citrulline is a non-essential amino acid that isn't commonly found in any food sources, except for fresh watermelon.

It's a popular ingredient that is often found in pre-workout supplements to optimize muscle pumps and performance. 

''Oral L-citrulline and citrulline malate supplementation have shown to increase plasma citrulline and arginine concentrations, along with total nitrate and nitrite concentrations.''

L-Citrulline has been scientifically shown to improve exercise performance and recovery (1). It also more effective at raising NO levels compared to L-Arginine, making it a better choice (2).


2. Beet Root Extract

Another one of the best nitric oxide supplements is Beetroot extract. It's effective at increasing NO because Beetroot is rich in nitrates (3).

It's becoming more and more popular to include in supplements because it doesn't just help with blood flow; it also helps improve high-intensity exercise tolerance (4). Beet Root For Nitric oxide

''Beetroot juice contains high levels of inorganic nitrate (NO3−) and its intake has proved effective at increasing blood nitric oxide (NO) concentrations.''

With the increased blood flow and exercise capacity, beetroot extract is a great, powerful ingredient often included in stim-free pre-workout supplements.

It's also worth mentioning that beetroot extract is rich in flavonoids, ascorbic acid, and carotenoids. This makes it a potent antioxidant that may have other interesting health benefits.

3. Pomegranate Extract

Pomegranate extract is another ingredient that is high up on our list of best nitric oxide supplements. The reason for it being that is that pomegranates are also a rich source for nitrates and polyphenols.

Nitrates help form nitric oxide in the body (5). With more NO production, your blood vessels start to relax, and blood circulation is improved. 

''Pomegranate juice doesn't only just protect nitric oxide; it also enhances the biological actions of NO.''
Polyphenols help protect nitric oxide, thus making the actions more effective. We find that Pomegranate extract is a key ingredient in boosting NO.

4. Glycerol

Next on our list of best nitric oxide supplements is Glycerol. This ingredient works by increasing osmotic pressure in the cells, which causes water to be drawn into those cells. Your cells will have more volume and expand.

When your cells expand, you'll notice fuller muscles and better pumps. This is cause your muscle's cell capacity has increased temporarily due to the water.


Supplements often contain a patented form of glycerol powder called Glycerpump. Glycerpump contains 65% of glycerol powder, making it a more stable form of Glycerol that is better absorbed by the body, resulting in better effects.

Besides that, glycerol supplements also positively influence exercise performance (6).

5. L-Arginine

Last but definitely not least on our list is an amino acid called L-Arginine. It's found in dietary sources such as red meat and fish (7).

L-Arginine is a precursor for the synthesis of nitric oxide (8). This means that it helps increase theformation of NO production. 

L-Arginine Nitric Oxide
''l-Arginine is a semi-essential amino acid that is the substrate for nitric oxide production by vascular endothelial.''
Besides the fact that L-Arginine shows promising effects on boosting NO production, it might also have positive impacts on exercise training and metabolism.

The Best Nitric Oxide Supplement On The Market

We've shown you the most potent ingredients that can help boost nitric oxide production. Increasing your NO production can help you take your workout performance and intensity to the next level.

Sourcing each ingredient will be difficult, but we've formulated a product that combines all key NO ingredients.

That means you won't have to search any further.

Allow us to introduce you to Pump Serum, the best nitric oxide booster supplement on the market.  


Pump Serum contains all the ingredients you should be looking for when it comes to optimizing NO production. In one serving of our nitric oxide supplement, you'll find:

The unique combination of potent ingredients will help shuttle more blood, nutrients, and oxygen into the muscles. That means with one scoop of Pump serum, you'll experience extreme muscle pumps, focus, and muscle fullness.

For those who want to get in an intense workout, you can choose to stack this product with our other high stim pre-workout called Wrecked.

Frequently Asked Questions

How can I increase nitric oxide naturally?
It can be quite challenging to increase nitric oxide naturally, so most of us choose to use supplements instead. However, if you're dead set on increasing it naturally, you should start with:

  • Start eating more food sources that are rich in nitrates. A few examples are beetroot, spinach, and celery.
  • Make sure to exercise regularly to improve blood flow. Try training at least several times per week.
  • Start increasing the number of antioxidants you take, preferably vitamin C or E. They help maintain high amounts of NO by preventing breakdown.

By implementing these tips, you'll be able to increase those levels naturally although it might take longer compared to supplementation.

What foods are high in nitric oxide?
There are plenty of foods out there that can help increase your nitric oxide levels. The best foods are red meat, fish, green vegetables, beets, and dark chocolate.

How long does it take for nitric oxide supplements to work?
Once you've taken a NO supplement, you start noticing the effects rather quickly. Generally speaking, it takes about 30 to 45 minutes. More blood, nutrients, and oxygen will be able to reach your muscles for a few hours. This will result in fuller, harder muscles. Therefore, the use of these supplements is very common among athletes and bodybuilders.

Do nitric oxide supplements really work?
Yes, they work, but it depends on the product's formula. As we previously mentioned, you need potent ingredients to make it happen. Therefore, we advise going with a product such as Pump Serum, which contains the same clinically proven ingredients we've discussed in our article.
