In today’s modern world, having an exercise schedule is a necessity. This is largely so because most of the work people do nowadays involves sitting in a chair all day, which could lead to multiple health problems. 

Nearly every cell in your body produces nitric oxide, an essential molecule to improve and maintain blood vessel health.You can also try muscle building supplements to help with that. Nitric oxide is available in almost every pre-workout you can find since it helps promote muscle recovery, which allows you to sleep better. 

The biggest complication with nitric oxide is finding a good supplement that provides guaranteed results. Since there are tons of companies selling such stuff, all are promising to provide the best results, finding the best one is hard. So, we did the research and found the best brands offering the best nitric oxide supplements.

Our Top Picks For The Best Nitric Oxide Supplements 

#1. Stim-Booster by Transparent Labs – Overall Best Nitric Oxide Supplement, Editor’s Choice

As the name indicates, Transparent Labs aims to provide the best pre-workouts to its customers without hiding anything. They don’t just create a product; they use scientifically-backed ingredients in their products and provide evidence that the ingredient will work. With the careful doses of each ingredient and zero junk, they offer clean products with zero side effects.

If you want to improve your workout routine with quick post-workout recovery and increased stamina, Stim-Booster is the best nitric oxide supplement. We chose this particular supplement because it passes our criteria by a mile. It is affordable and has all the necessary ingredients to provide a quick energy boost for your workout. The only thing you won’t find is flavors, and there is no subscription available on this product, so you can only get a discount by purchasing a bundle.

Stim-Booster is available in powder form and it comes with a measuring scope for ease of use. Add one scope to 12-16oz water or any of your desired beverages. Do not mix it in coffee, as you might not like the potentially overwhelming energy boost you’ll get by mixing these two. Drink it half an hour before your workout, preferably in the morning. That way, you can spend the entire day full of energy.

Transparent Labs has over 4.5-star ratings on every product they have on the website. With over 15,000 reviews available, you can easily learn about any product you wish to purchase. Opt for standard shipping as it will deliver products quickly, and you can track your delivery from anywhere. You might need to pay a bit, but it is much better than the default shipping method, where you have no track of your purchase. Return the product undamaged within 60 days, and the company will refund the money within one week.


60 Servings per Container: One of Stim-Booster’s most noticeable features is its cost convenience. You can use one container for up to two months, which will only cost you around $15. However, its small servings might not provide you with enough energy. So, the chances are that you’ll use it more than once daily. Furthermore, it’s unlikely that one container is enough for multiple pre-workout consumptions, so be ready to order another container at the end of each month if you decide to do cardio in the morning and heavy workout at night.

2000mg of L-Citrulline: L-citrulline is responsible for boosting the nitric oxide levels in your body as it improves blood circulation. Thanks to this, you’ll get an instant energy boost after using this supplement. Granted, this isn’t the largest dose of citrulline on the market. But, considering the price, it is fair enough. The downsides of this product are that it is not available in multiple variants, the dosage is fixed, and you have to stick with such an amount. If 2 grams of citrulline is not working for you, check another product from the list below.

Gluten-Free and Non-GMO: Stim-Booster is an excellent option for all vegans as it is free from animal by-products. Only six ingredients are available in this supplement, and the company mentioned that all of them are vegan-friendly. Stim-Booster can help them overcome the nitric oxide deficiency from not eating meat. You can also check their lab reports to confirm that no animal or dairy product is added to this supplement.

Allergen Control Program: Transparent Labs have products that contain nuts, but the company cleans the equipment properly before processing a non-nut based product. That said, if you have a nut allergy, you can rest assured that Stim-Booster doesn’t contain nuts.

Helps Improve Mental Health: Your brain requires continuous oxygen to work properly, and your red blood cells are responsible for taking oxygen to the brain. Stim-Booster improves your blood flow, so your brain gets oxygen-rich blood to improve focus and overall mental health. You’ll feel less lazy and more active in your work.

Easy Return: Transparent Labs has a unique policy for their powdered supplements. Unlike other brands that only offer refunds on an unopened container, this company offers refunds as long as the container has some stuff left. Even if you used 80% of the powder and the results were not as expected, you can return the product for a refund.


  • No artificial sweeteners

#2. Pre-Kaged Elite Clinically Tested And Approved Nitric Oxide Supplement Brand

Kaged started its operations in 2014 with one goal: to offer health-focused products that provide the best results. This is one of the most famous brands with the best workout supplements, and they have a massive product line to fulfill their customers’ needs. Besides supplements, they also offer multiple courses to ensure that you follow a schedule that improves your lifestyle. The best part is that all the courses are available for free.

From their product list, we chose Pre-Kaged Elite because it has an all-in-one formula that works how you want it to. It has all the ingredients required to build lean muscles and mass, reduce weight, improve blood flow, provide energy, and much more. Your workout will determine how this supplement should affect you, and your diet will also play an important role.

Pre-Kaged Elite is expensive compared to the other supplement we shared, and its serving size is also small. However, one container has enough L-citrulline to provide noticeable results within a month as reported by other users. Since this is a potent supplement, the company recommends starting with a half spoon and seeing how your body tolerates it. If half a spoon is enough for you, one container could last 40 days.

Kaged has the best shipping packages. That is, you get free shipping over the purchase of $50, and it takes around two to three business days to deliver the product. The company only processes the orders till Friday, so you should order before the weekend to get your package on Monday. International shipping gets costly as it includes duties, custom tax, insurance, and value-added tax.

The company only accepts returns if the container is half full and offers no guarantees for international returns. You have 30 days to return the product after it is delivered.


Available in Three Different Flavors: Pre-Kaged Elite is available in strawberry lemonade, glacier grape, and fruit punch. We recommend that you get the glacier grape flavor as you’ll likely love how cool it is, and the sweet taste of the grape will refresh your body. However, try the strawberry lemonade flavor if you want to chug it fast. It tastes like a regular lemonade. Plus, if you use cold water, you can drink it quickly and instantly feel fresh. The fruit punch is for those who can’t decide on a single flavor. Thus, they can enjoy a bit of cocktail taste, but it might not be as good as the other two flavors.

29 Ingredients in One Container: Most brands usually use common ingredients, which does work, but their results are pretty average. Kaged created nine unique ingredients and patented them so no one else could use them without the company’s permission. You get a combination of nine unique and premium ingredients in Pre-Kaged Elite. These ingredients are why the company decided to keep this product expensive, but it will provide long-lasting results in less time.

Subscription Available: There is no bundle discount on Pre-Kaged Elite, but the company offers a free subscription to provide a flat 10% discount. Additionally, you can opt for automatic delivery every 30, 45, or 60 days based on how much you purchase. The company will notify you about the automatic delivery, and as you confirm, they’ll deliver the products. You can cancel the subscription anytime or cancel the automatic delivery if you are away from home for a couple of months. The company won’t send anything until you acknowledge the confirmation mail they’ll send you.

Speeds Up Metabolism: Another unique thing about Pre-Kaged Elite is that it helps improve your metabolism, which improves your digestion, and you get more energy from the food you eat.


  • Extended energy
  • Focus, pump, and strength
  • Best for gaining muscle mass
  • Health-conscious


  • Relatively expensive
  • Fewer servings if one spoon is used daily

#3. Pump Surge by Jacked Factory – Most Popular & Recommended Nitric Oxide Supplement

Jacked Factory started its operations in 2015 with the aim of providing people with the help they need to build muscles. This is one of the most famous brands regarding pre-workouts for mass building. However, after its release, the company realized that not everyone wanted to build mass. Some just want to stay fit and full of energy. Thus, they changed their ways and created supplements for those who want an energy boost to keep them active.

Among their huge collection of pre-workouts, we chose Pump Surge because of its unique formula. It does not have caffeine, so you won’t have caffeine tolerance issues. The company recommends mixing one scoop of Pump Surge with water, but you can mix it with any beverage of your choice, including stimulant pre-workout mixes for better muscle growth and pain recovery. This is possible because Pump Surge is a stimulant-free supplement. 

Furthermore, the brand values transparency. As such, all its ingredients are mentioned on the label and the website, with each ingredient backed by a scientific study. It is not expensive, has 20 servings in one container, which barely lasts a month. However, starting with a half spoon is recommended and mixing it with water to see how your body reacts. If you find the results desirable, continue with the half spoon dosage; otherwise, take a full spoon. Stop using the supplement and consult your doctor if your body shows any aggressive reaction on the first attempt; stop using the supplement and consult your doctor.

It takes around three to five business days within the USA and 7-21 days for international shipping. The company provides a full refund or an exchange if you get a damaged container out of the box.


Multiple Discounts Available: You can get a 10% discount on your first order and an additional 15% discount if you choose a subscription. The company will automatically deliver the product after one month once you become their subscriber. If you choose a bundle, make sure to set the delivery time to every two or three months, so you won’t end up having lots of containers at home.

Hassle-Free Money-Back Guarantee: The brand is so confident in its products that it won’t even ask for a return reason. You can send them the mail for the return within 90 days of purchase, and get a full refund. However, you won’t get the shipping cost back or any other charges you paid to get the product, like duties or customs.

More Strength, Power, and Drive: By default, this supplement will provide your body with enough energy, but since this is a stimulant-free formula, you can mix it with other supplements and get even more strength. Some supplements are not made to help manage the post-workout pain, so people have to rely on other supplements. Most bodybuilders have to take one supplement for mass gain and one to help manage the pain. While it is a good option, mixing two stimulants pre-workout can sometimes bring side effects. Pump Surge has no side effects and won’t cause adverse reactions if you stack it with any stimulant pre-workout. You can even stack it with other nitric oxide boosters. Just be sure that whatever you’re mixing it with wouldn’t cause any problems.

Made in a cGMP Certified Facility: Pump Surge is made in authorized facilities to ensure its safety, potency, and quality. The company also puts its products up for lab testing to ensure that its products are safe to consume before they hit the shelves.


  • It helps improve cognitive function, memory, and more
  • No caffeine
  • No fillers or dyes
  • Endless Endurance
  • No fillers


  • Low citrulline dosage

How We Made This List Of The Best Nitric Oxide Brand?

While making this list, we looked for products that provide good results and won’t cost you a fortune. Quality supplements can get expensive, and most people are not okay with spending hundreds of dollars monthly. So, we found brands that provide discounts to make it convenient for people to buy.

We opted for products with natural ingredients only in the best quantity for better results. Additionally, the supplements we chose are quite easy to use. Straightforward dosage instructions are available on their websites and packaging. Finally, we checked their reviews to confirm their effectiveness. If people who used them rooted for those products, we added them to our list.

What We Looked For?

  • Price: The first thing we checked was the price of every supplement we came by, and we chose those providing value for money. Those brands did not offer cheap and low-quality supplements but had multiple discounts to lower the prices. Since you’re likely to be using the supplements for a couple of months to get the best results, it is better to grab a bundle for a discount. Additionally, we checked the servings offered in one container and how much you should use daily. It might not seem important, but you can save a lot of money by using one container per month instead of two.
  • Natural Ingredients: You’ll see some common ingredients in every energy-boosting supplement. Some companies add some additional ingredients to boost the results. Every ingredient they use should be natural and backed by scientific evidence to boost the nitric oxide levels. While looking for the products, we checked their ingredients and did a separate search on how helpful they are in increasing and maintaining your body’s energy levels. Additionally, there are no artificial ingredients in our choice of products as such ingredients often bring nothing but distasteful side effects. 
  • Easy to Use: We only chose those supplements that are straightforward to use, and the company is generous enough to mention the instructions to use them. Moreover, some people find it hard to swallow the pills, so we chose powdered supplements. That way, you can easily mix them with water and drink them 30-40 minutes before your workout and get the best results.
  • Effectiveness: Finally, we chose the supplements on our list after looking through their reviews and confirming that they are effective and provide the desired results within reasonable timeframes.

Buying Guide: Factors to Consider While Choosing Nitric Oxide Supplements

If you choose the wrong product, these supplements can cause adverse side effects. You should look for not only the products but also the brands. After all, if there is a problem, the brand is responsible for it. To help you make the right choice, here are a couple of factors you should consider to purchase a supplement from your local or online store. 

Customers Safety

Any brand offering such products should be able to clarify that their products are safe to use. There are many ways to certify the safety of their products. For starters, they can put their products for tests and provide lab results. They can also distribute their products among the professionals and share their opinion on the website. Additionally, they can also share the initial effects you can experience on your first use. That gives relief to the customer; knowing what they experience is common.

There is no need to follow a brand unsure about its product’s results. You might see dozens of positive reviews on it, but if the brand itself is not offering surety, who knows what effects you’ll experience while using the product.

Satisfactory Results

Most brands are open about their product’s results and how quickly it works. The basic idea of using these supplements is to increase nitric oxide levels. While nitric oxide supplementation can also bring other effects on your body, which the company should mention, knowing that your desired product will bring satisfactory results so you can use it with peace is better than being entirely unaware.

You can always check the product’s description to see how long you have to use it for the best results. You might need to take a break from these supplements, so your body shouldn’t solely rely on supplements to produce nitric oxide. Check for all these factors before choosing a product.

Brand Reputation

A new brand in the market will always deliver products at lower prices to attract customers. Trusting a new brand for such supplements is not a wise option. It is better to learn about the brand, how long it has been operating, how many customers it has served, and its rating on popular platforms like TrustPilot before deciding. A reputable brand has an image to maintain, so they’ll treat their customers in the best way possible.

Quality brands only opt for the best and most natural ingredients to manufacture nitric oxide boosting supplements. Check how transparent they are about their methods and processes. A brand providing such information to its customers means they want to establish a long-term relationship.

Guarantees and Shipping

Money-back guarantee is mandatory when it comes to purchasing online products. Since such supplements take around a month to show results, it is better to go for a brand that offers a 30-day money-back guarantee. Moreover, the brand should not ask many questions and offer a full refund on every unopened container. Most people tend to grab a bundle for a discount and will be delighted to get a full refund on the products they didn’t use.

The shipment time should be short and no one should have to wait a week to get the supplement. The local shipping should not take more than two business days; if the brand is shipping internationally, it should not take more than 15 days.

Third-Party Lab Reports

USA regulatory authorities won’t allow supplements to reach the shelf before undergoing independent lab tests. Unfortunately, some brands try to dodge this requirement and still claim that their products have been tested by independent labs. The only way to uncover a fake brand is to check for lab reports. Most brands provide a lab report alongside the product, while some have a dedicated section.

You can check the website for the lab reports and check what ingredients and potency the product has. The company might be able to provide fake information, but the lab reports won’t lie as those labs are not working under any company.


This can be treated as an optional factor to consider, but if you can’t handle the bitter flavor of supplements, going for a flavored one is preferable. That said, you should ensure that the company only uses natural fruity flavors and that the fruity taste is not too strong. A strong flavor can ruin the potency of a nitric oxide booster or indicate that the company is using artificial flavors.

While finding a brand that offers many flavors is not necessary, having two to three flavors is great. You never know which flavor you like the most, and if the company only offers one flavor, it might not suit your taste buds.

Customer Reviews

Customer Reviews contain all the information that a brand can’t share. Since these supplements’ effects differ based on your body, you can never expect the exact same results mentioned by the brand. At such times, it is better to check the customer reviews and see what those who used this product have to say about it.

These reviews will often contain information about a supplement’s prolonged usage, how quickly it affects a certain body, and any side effects. While brands promote their products to have no side effects, there are always some minor issues associated with such products.

FAQs Related To Nitric Oxide Supplements

What boosts nitric oxide the most?

That depends on how quickly you want results. A supplement will boost your nitric oxide levels in less time, but you should use them when your body doesn’t create nitric oxide from a natural diet. Supplements are not necessary if your body is doing fine. There is no need to push your body to its limits as it might cause a few unwanted side effects. 

Garlic and meat have the best amount of nitric oxide, but it is not advisable to eat large amounts of meat daily. As an alternative, you can also opt for beets, pomegranate, citrus fruits, nuts, and seeds. Dark chocolate is another excellent option, but not everyone is a fan of its taste.

How do I naturally increase nitric oxide in my body?

One way is to eat a nutrient-rich diet and follow a good exercise schedule. Another way is to use pre-workouts to get a solid boost to increase nitric oxide in your body. Exercise is a must to keep your body in a balance. Vegetables are your best friend for nitric oxide, and you can also eat a little bit of meat daily to get the necessary energy boost. A supplement should be your last resort because there is generally no need for a supplement if you stick to a good diet and do a little cardio or exercise daily.

What vitamins should I take for nitric oxide?

You need only two vitamins in any nitric acid supplement you purchase – l-arginine and l-citrulline. They are present in every pre-workout or energy-boosting supplement, red meat, dairy products, poultry, and fish. L-arginine is an amino acid; a protein-building block converted into nitric oxide inside your body. It can also improve your blood circulation and help remove the problems with your blood pressure. Additionally, vitamin C also enhances nitric oxide levels, increases its bioavailability, and maximizes its absorption in the body.

Who should not use nitric oxide supplements?

People with asthma problems and allergies should be cautious while using these supplements. They’ll increase the blood flow, which then takes more oxygen towards the brain, increasing your breathing. Thus, an asthma patient might have problems using these supplements. 

Additionally, if you are allergic to any ingredient commonly used in nitric oxide supplements, a high potency supplement can give you lots of issues. You can always check the ingredients list to see if there are possible allergens listed there or not. Beyond that, if you are already on blood pressure medications, talk to your physician before choosing a supplement. Diabetic patients should also get medical advice before using a nitric oxide supplement.

Which is better, L-citrulline or L-arginine?

You’ll need both if you want to increase your nitric oxide levels, but citrulline works much better. It opens your blood vessels, allowing improved blood flow. It might take more than three months for L-citrulline to show noticeable results, but you’ll feel an instant energy boost within 24 hours. You should use a supplement for up to eight weeks and monitor your body changes. It is better to take a month’s break after using such supplements for recommended time so your body can make nitric oxide naturally instead of relying solely on the addendum.

What happens if I overdose on these supplements?

Overdosing never brings anything good. Even if the product is not working for you, change it but don’t go beyond the recommended dosage. Overdosing can lead to side effects like consistent headaches, breathing issues, body pain, and vomiting. Excessive vitamin C may lead to stomach cramps, nausea, and diarrhea. If your desired product has selenium, it can cause hair loss, fatigue, and gastrointestinal upset. L-carnitine can also cause a “fishy” body odor, which gets stronger as you sweat or keep using these supplements. Stop using the supplement if you feel any extreme reaction and consult your doctor immediately.

Can nitric oxide supplements help cure erectile dysfunction?

These supplements won’t cure such issues, but they can temporarily help. You experience erectile dysfunction when the blood is not properly flowing towards your penis, and it won’t get hard no matter how much you try. A nitric oxide supplement will improve your blood flow, forcing it to reach all body parts where it is required. Since you’ll get a boost from these supplements, you’ll likely erect quickly. However, for a permanent solution, you’ll need medicines or supplements that are made to cure erectile dysfunction. To find the best one for you, it’s best to consult your doctor as not every product is trustworthy or good for your health.

Is beet root extract a good source of nitric oxide?

Beetroots are high in nitrates that get converted into nitric oxide in your body. Beetroot is a common ingredient in most pre-workout or other supplements to increase blood flow and stamina. You can also find beet powder and add it to your daily diet to get a minor nitric oxide boost, which would provide adequate energy for the day. Another benefit of beetroot is that it lowers blood pressure, making it a great companion for those who can’t handle their anger and have high blood pressure.

Does L-arginine work like Viagra?

Viagra is quite a potent pill to help manage erectile dysfunction. L-arginine only improves the blood flow. It might help you get an erection, logically speaking. It might also heighten the effects of viagra if used alongside the pill. However, most supplements with l-arginine aren’t designed for solving erectile dysfunction problems. Furthermore, you might experience low blood pressure if you use l-arginine with other ED medications. If you have ED because of poor blood flow, there is a remote possibility that l-arginine could be a better option than viagra. However, to be on the safe side, it’s best to simply consult your doctor first. .

Should I take nitric oxide supplements daily?

It depends on the supplement you purchase. If the recommendation is to use it daily, you should follow it. Most supplements require you to take them 30-40 minutes before your workout daily. However, after two to three months, most brands recommend that you take a break for two to four weeks before using the supplements again. Moreover, you can consult your doctor about its usage, especially if you experience any reaction after the first dosage.

Conclusion: Which Are The Best Nitric Oxide Supplement Brand?

Supplements are becoming common as people’s work-life puts more stress on the brain than the body. A tired brain can’t function properly, and a body that hasn’t done any exercise won’t get tired easily. The trend of fast foods made things even worse, and those who are not eating quality and clean food face even more problems. Our choice of nitric oxide supplements might not be able to help overcome all the issues, but they can help improve brain health, manage body pain, and provide you with enough energy to stay active the whole day.

We shared three of the best nitric oxide supplements, each offering different results besides boosting your nitric oxide levels. If you want a light energy boost, try using Stim-Booster, but Pump Surge is the best option if you want muscles. Start with a low dosage. If the energy levels are insufficient, increase the dosage but don’t go beyond the recommended level. Contact your physician immediately if your body shows any strange or strong reaction after taking any of these supplements, and don’t use them again until your doctor clears the issue.
