The 10 Best Nitric Oxide Supplements For Boosting Blood Flow
Nitric oxide (NO) is naturally produced by our body and plays a vital role in our health. Its primary purpose is to widen and relax the blood vessels in our body, so that blood, oxygen, and nutrients can reach your cells at an optimal rate.
That means when NO is increased, you can experience several benefits such as getting more blood in the muscles and better nutrient absorption.
Increasing the amount of NO in the body can be done through the use of nitric oxide supplements. These unique supplements contain ingredients that can help the body accelerate the production of NO.
The 10 Best Nitric Oxide Supplements Of 2021
What if I told you that dozens of so-called ”nitric oxide booster” supplements don't contain the right ingredients or are underdosed, meaning they won't boost NO production at all.
That's why we've taken it upon ourselves to test all the popular nitric oxide boosters on the market.
Because at SupplementsReviewer, we like knowing which products are worth the money and which to steer clear from.
Keep reading to find out which products are the most effective, how to use them for optimal results, and where to purchase them for the best price.
The best nitric oxide supplement out on the market right now is Magnify, produced and sold by Huge Nutrition.
It's incredibly effective at boosting NO production, and we've experienced this first-hand.
We've concluded that it's the best because it only consists of scientifically proven ingredients, meaning you can't go wrong with Magnify.
The use of science-backed ingredients is a game-changer because when a product contains the right compounds, that's when you're going to feel the effects.
Here's what you will find in a serving of Magnify:
- 1000mg Beet Root Extract (Beta Vulgaris)
- 1000mg L-Arginine Complex (L-Arginine AKG, L-Arginine, L-Arginine HCl)
- 1000mg L-Citrulline
- 500mg Pomegranate Extract (Punica Granatum)
- 50mg S7 (Green Coffee Bean Extract, Green Tea Extract, Turmeric Extract, Tart Cherry, Blueberry, Broccoli, Kale)
- 50mg Epimedium Extract (Epimedium Grandiflorum)
We like the fact that every single ingredient in Magnify contributes to maximizing the production of nitric oxide.
Take S7 (Spectra7), for example. It's a patented ingredient that has been shown to significantly boost NO production (1).
The only downside to Magnify is that there's a serving size of 5 capsules, which is more than it's competitors. On the other hand, more pills mean more ingredients, which will only help boost NO production.
Right now, you can get yourself a bottle of Magnify (150 capsules) for $39.95. Based on the wide variety of science-backed ingredients, we find that a very reasonable price.
It is only available on the manufacturer's site, Hugesupplements.com.
Other Huge Nutrition products we've reviewed: Annihilate, Sapogenix, Rebirth and Wrecked.
2. Steel N.O.7
N.O.7 by Steel Supplements is the second-best nitric oxide supplement on our list. We were much surprised by this product's effects, which is why it has made it to our exclusive top 10.
With the power of one single capsule, it has the ability to supercharge blood flow, resulting in great muscle pumps. Because of this, many athletes take it before starting their workout to help them boost performance.
This is what you'll find in the one-serving capsule of Steel's N.O.7:
- N.O.7 Blend: SurePumpTM (Punica granatum, (-) Epicatechin, 5-hydroxy-2-(4-methoxyphenyl)-8-(3-methyl-but-2-enyl)-7-[(2S3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy-3-[(2S,3R,4R,5R,6S)-3,4,5-trihydroxy-6-methyloxan-2-yl]oxychromen-4-one
We're not really familiar with some ingredients found in this product, but from what we could tell, it works. It has to be some potent stuff for it to work at just a one-capsule serving.
N.O.7 might be one of the best nitric oxide booster supplements, but it's expensive. One bottle costs $70.00, which holds 30 capsules.
That means you're looking at $2,33 per pill, meaning this can get quite pricey if you are using it on a daily basis.
If you're a big spender and don't mind paying extra, you can visit the official Steel Supplements site and order a bottle.
Other Steel Supplements products we've reviewed: Shredded AF, Alpha AF, Amped AF and Pumped AF.
3. Vintage Burst
Coming in right behind Steel's N.O.7, we have Vintage Burst by Oldschool Labs designed to maximize pumps, intensity, and muscle hardness.
What's in Vintage Burst? Here's an overview of the supplement facts:
- 1500mg L-Arginine HCl
- 150mg Maca Root Extract
- 100mg Spectra
- 100mg Coffeeberry
- 10mg Vanadyl Sulfate
What we like about Vintage Burst is the hefty dosage of L-Arginine, which's going to help with nitric oxide production, as seen in clinical studies (1).
We don't like the fact that it contains caffeine, because that's not what we're looking for in these products.
It's also good to know that Vintage Burst has been tested by a third-party to make sure they're providing you with a clean and certified product.
It can be purchased from the official Oldschool labs website or Amazon.
Other Oldschool Labs products we've reviewed: Vintage Blast and Vintage Burn.
4. Snap Nitric Oxide
The next product on our list is Snap's Nitric Oxide booster. It's a popular product on Amazon, where customers support its ability to help the body produce more NO.
This product doesn't just focus on boosting blood flow, but it's also designed to help keep energy and stamina levels high during a workout.
Here's what you will find in a two-capsule serving size of this supplement:
- 1500mg Nitric Oxide Complex (L-Citrulline, L-Arginine, L-Taurine, L-Norvaline, Vanadyl Sulfate, Tribulus Terrestris, Muira Puama Bark Extract, Asian Ginseng Root)
As you can see, Snap doesn't specify the exact dosages of each ingredient. That's the downside of this product; we don't know which dosages were used. This makes it hard for us to determine whether it's a reliable formula.
If you're like me and want to know exactly what you're taking so that you'll get the desired effects, we advise going with Magnify instead.
If you do want to go ahead with this product, it can be found on Amazon under the Nitric Oxide Booster category and will cost you roughly $30.00 with shipping included.
5. N.O. Pro
Another great product that has taken fifth place on our top 10 is Zhou Nutrition's N.O. Pro. It is also one of the top-featured nitric oxide boosters on websites such as Amazon.
Some of the ingredients found in this supplement can enhance blood flow and nutrient delivery. That means that this is an exciting product for athletes looking to optimize performance.
One serving of N.O Pro holds four capsules and contains the following:
- 1200mg L-Arginine HCl
- 1200mg Arginine AAKG
- 610mg Citrulline Malate 2:1
- 160mg Beet Root
Every compound found in this product has promising scientific data to prove that it works at increasing nitric oxide production.
It's good to see that this product only uses quality ingredients instead of useless fillers.
We would've loved to see the Citrulline and Beet Root at larger dosages to amplify the effects further, but it's a solid formula nonetheless.
When we look at what others say about this supplement, they're generally satisfied with the results it gave.
EVL Nutrition's Beet Mode is filled with concentrated beet crystals. With the concentrated power of beets, this product can supercharge your N.O. levels significantly.
One scoop of this supplement holds 6,5 grams and consists of:
- 4000mg Non-GMO Beet Root Powder
- 1000mg Organic Fermented Beet Root Powder
Beet Mode is also absorbed faster than regular beetroot supplements, meaning you'll notice the effects much quicker.
The only downside is that you're only going to the benefits from one single ingredient, whereas other products combine several elements.
It's also important to know that Beet Mode is rich in antioxidants, meaning it could offer more health benefits. It's also suited for vegans.

7. N.O. XT
N.O. XT by JackedFactory is the seventh product on our list of best nitric oxide supplements. If you've been searching for popular NO products online, chances are you've stumbled upon this product.
They claim to have only used premium ingredients so that you can experience skin-tearing pumps, maximum performance, and muscle growth.
Here are the ingredients found in JackedFactory's N.O XT:
- 1500mg L-Citrulline
- 500mg Nitrosigine
- 200mg L-Glutathione
- 5mg BioPerine
Why isn't N.O. XT higher up on our list if it's so popular? Well, we think it's pretty overhyped as there are only three ingredients in there at moderate dosages.
Just because we think it's overhyped doesn't mean we don't like it; it's still a decent product. However, we're convinced products such as Magnify will do a much better job because it contains more.
Other JackedFactory products we've reviewed: Burn XT and Nitrosurge Pre-workout.
8. Nitric Oxide Boost
The next nitric oxide booster supplement on our top 10 is developed and sold by Double Dragon Organics.
A serving of Double Dragon Organic's N.O booster is two capsules which contains a proprietary blend:
- 1600mg Proprietary Metabolism Blend (L-Arginine HCl, L-Arginine Alpha-Ketoglutarate, Citrulline Malate)
We're not fans of proprietary blends because it doesn't tell us the ingredients' dosage in here. With that said, this product does contain the staple compounds one should look for.
9. Hard Iron N.O.
The second-last N.O. supplement on our list was designed to help athletes take their performance to the next level.
The company behind this product, Hard Iron Labs, claims that it can help you get bigger pumps, better performance, and vascularity.
To help you get those benefits, it uses a combination of different ingredients. These ingredients include staple compounds such as Arginine, Citrulline, and Beta-Alanine.
Of course, it's not our first pick, but that doesn't mean it's not a reliable product. You can pick up a bottle of this stuff for roughly $30.
10. Orphic Nutrition L-Arginine
The final product is simple yet effective at stimulating the body's N.O. production. Meet Orphic Nutrition's L-Arginine, their nitric oxide booster formula.
What do you get in a serving of Orphic Nutrition's product? Here are the ingredients:
- 30mg Niacin
- 30mg Calcium
- 400mg L-Arginine
- 400mg L-Arginine AKG
- 200mg L-Citrulline
- 200mg L-Citrulline Malate Extract
- 80mg Beta-Alanine
It may not be the most stacked product out of our list, but this supplement contains all the staple ingredients one should look for when it comes to a nitric oxide booster.
With that said, we find that it has relatively low to moderate dosages, which could make it less effective than the other products we've featured in our top 10.
If that doesn't bother you and you're looking for a mild product, you'll be able to find this product on the official site of the manufacturer.
What To Look For In A Nitric Oxide Booster
The ingredients are what determines the effectiveness of a supplement. So that's exactly what you have to look for in a nitric oxide booster – a good set of ingredients.
When we look at the ingredients in supplements like these, we look at whether it actually can increase the amount of nitric oxide.
As supplements reviewing experts, we've learned a lot about ingredients throughout the years.
Here's an overview of some of the most effective ingredients found in the best nitric oxide supplements.
L-Arginine is a naturally occurring amino acid that changes into Nitric Oxide once it enters the body (1). It's by far one of the most prevalent compounds to boost the production of NO, which is why you'll see that many supplements contain it.
You can find L-Arginine in many different food sources, some examples are turkey, chicken, lentils, and peanuts. If you're looking for ways to boost NO naturally, try eating more of the foods mentioned above.
Beet Root Extract
Beet Root Extract, also known as Beta Vulgaris, is highly effective at increasing nitric oxide. It's such a useful ingredient because Beet Root has a high nitrate content (3).
That means the consumption of beets can help promote vasodilation, muscle contractions, and blood flow.
It could also help with delaying muscle fatigue associated with high-intensity exercise, but more research is required.
This is a great ingredient to include in a nitric oxide booster, and athletes will benefit greatly from it because of the benefits, as mentioned earlier.
Another excellent ingredient is L-Citrulline, a nonessential amino acid. It's also one of the staple ingredients found in nitric oxide supplements and pre-workout supplements.
The reason for this is that it's great at boosting increasing blood flow and exercise performance.
Research also shows that it can improve the bioavailability of L-Arginine, meaning the body can absorb it better and therefore enhance NO (2).
A newer ingredient that has hit the market is S7™, a patented combination of plant-based ingredients. The mix consists of green coffee bean extract, green tea extract, turmeric extract, tart cherry, blueberry broccoli, and kale.
We're massive fans of this ingredient because clinical research has shown it to increase nitric oxide by up to 230% (4).
Magnify is the only product in our top 10 containing 50mg of S7, delivering a massive boost in NO levels.
Do Nitric Oxide Supplements Have Side Effects?
Nitric oxide supplements should not cause any severe side effects in healthy individuals. Some users have experienced slight side effects such as headaches, nausea, and an upset stomach.
But generally speaking, you won't notice any negatives when using these types of supplements as they mainly contain safe, natural ingredients.
If you have a medical condition, you should consult your doctor about the usage of these supplements. This is important as it will prevent you from experiencing adverse effects.
Many of you have also asked us whether it's safe to stack with other supplements, and the answer is yes. I like combining them with a BCAA supplement or a fat burner when I'm cutting down.
It's evident that Nitric Oxide plays an essential role in making sure blood, nutrients, and oxygen reach your cells effectively.
By increasing the amount of NO in the body, there are many benefits to be experienced. If you want to increase those levels significantly, you're going to need to use the best product you can get your hands on.
