Although we doubt some of NitriLean’s claims, the product does contain a proven blend of nitric oxide boosters, including beetroot and L-citrulline. Sadly, the doses are substantially lower than many of the other formulas, so NitriLean is lower on our list (there are only 100mg of beetroot and 220mg of L-citrulline, both of which are far lower amounts than those used in studies).

Drachen could be the true solution for you if you don’t like the concept of swallowing a capsule or pill and want a high-powered liquid mix instead. It currently starts at $50 for a one-month supply.

Rasputin Herbs Siberian Green


Rasputin Herbs from Siberian Green is a dietary supplement that claims it is based on a traditional Siberian remedy for sexual dysfunction.

Rasputin Herbs is a herbal and plant extract blend that is supposed to increase sex drive and libido in males. It contains horny goat weed, maca root, and Tongkat Ali, which are shown to boost testosterone levels in men or to improve libido and fertility.

Siberian Green’s Rasputin Herbs is one of the best-value alternatives on our list, with a price tag of under $16.

How We Ranked The Best NO2 Boosters

Every single NO2 booster claims to raise your NO2 production effectively. However, not every NO2 booster works like it is advertised. To separate the very best from the very worst NO2 boosters, we used the following ranking factors:

Science-Backed Ingredients

Several ingredients are clinically proven to raise nitric oxide production. Others are shown to enhance blood flow in other manners. For example, beetroot is one – if not the most well-known ingredient to boost NO2 levels. We preferred products that used high-quality, scientifically-backed ingredients to back up their claims.

Clinically Studied Dosages

Many supplements contain the right ingredients but the wrong dosages. It doesn’t matter if the supplement contains the right ingredients if the dosages are incorrect. Some supplements include doses that are far too tiny to impact the human body. The label may appear impressive, but the manufacturer simply uses too little amounts. Some supplement producers even utilize unique formulas to disguise low dosages and make them appear more powerful than it really is. We preferred products that used clinically studied dosages.

Ease of Use, Flavor, and Convenience

Ease of Use, Flavor, and Convenience: Some nitric oxide booster pills taste awful. Others are quite tasty. Some require you to take six capsules every morning, while others only require one scoop of powder. We looked at simplicity of use, flavor, and overall convenience in creating our rankings. It should be simple, easy, and convenient to use a NO2 booster.

Formulated by Medical Experts

Medical experts (MDs) and PhDs with decades of experience have formulated some of the most popular nitric oxide supplements. Marketing teams developed others, who conducted a simple Google search for the greatest nitric oxide booster ingredients to throw a product together with no medical backing. Which would you choose to take? Qualified experts’ Nitric oxide booster products were more appealing, and we ranked them higher.

Transparency and Honesty

The supplement industry is riddled with shadiness, and sketchy companies and the NO2 booster niche are not different. Some nitric oxide booster supplement companies have a shady reputation for misrepresenting the benefits of their products. Some supplements promise to help you lose 30 pounds in a week or cure heart disease overnight. None of these statements are true (or even legal to claim per the FDA). We chose open and honest companies regarding nitric oxide supplements and what they could potentially do.

Price & Overall Value

Many NO2 boosters offer incredible value, charging affordable prices for high-quality formulas. Others charge a premium price despite offering a similar formula and dosages. We considered price and overall value in our rankings. If you pay for a premium, you should expect premium quality.

Money-Back Guarantee

Not every NO2 booster will work for everyone. If you don’t see any results, you should be entitled to get your money back. We preferred companies that offered at least a 30-day money-back guarantee.

Customer Reviews

At the end of the day, the best way to get an idea of the best NO2 boosters is to look at customer reviews. After all, this tells us the average experience of the customer. Did they see the results? Were there any side effects? Would they recommend the product to their friends and family? We read customer reviews to get answers to all these questions.

What is Nitric Oxide?

Nitric oxide is a naturally occurring chemical that causes blood vessels to dilate.

Production of hormones like insulin and growth hormones are also influenced by nitric oxide. Several nitric oxide supplements help cardiovascular health, hormone balance, and muscle recovery.

To widen blood flow, certain drugs use nitric oxide-like effects. Viagra, for example, improves blood flow by expanding blood arteries and increasing blood flow to the penis through nitric oxide pathways.

How Do Nitric Oxide Supplements Work?

Nitric oxide supplements contain natural compounds that help your body produce more nitric oxide. Some supplements directly increase nitric oxide levels by supplying you with nitrites and other precursors of nitric oxide. Others bring it up in a secondary manner.

Beetroot, L-arginine, and L-citrulline are the most common components in nitric oxide supplements. When consumed in the correct dosages, these three substances have been demonstrated to enhance NO2 production.

Main Benefits of Nitric Oxide Supplements

NO2 supplements can be used for any number of reasons. Some people take NO2 boosters to improve their sexual performance, whereas others simply want to lower their blood pressure slightly.

There are plenty of benefits of nitric oxide supplements, which include:

Support Heart Health

Nitric oxide supplements have been shown in several studies to help with arterial stiffness, blood pressure, blood flow, and other factors that make it easier for your heart to perform its duties properly. It’s better for your overall health when your heart can easily function. It reduces the risk for heart disease as well.

Improved Athletic Performance

Nitric oxide improves athletic performance by increasing blood flow throughout the body. That means oxygen, nutrients, and other beneficial compounds may circulate more easily throughout your body. Therefore, you can expect better results whether working out at the gym or lying in bed.

Faster Recovery

Your body requires oxygen and other nutrients to heal itself after you exercise. Nitric oxide supplements can improve sports performance, reduce pain, and reduce soreness after exercising by increasing oxygen flow to muscles.

Improved Sexual Performance

Nitric oxide pills are popular among guys who want to improve their sexual performance because these supplements improve blood flow. Even many prescription drugs work similarly. For example, Viagra works by increasing blood flow through nitric oxide pathways, making it easier to achieve and maintain an erection. In several clinical studies, nitric oxide supplements were found to help with erectile dysfunction, stamina, and overall improvement in the bedroom.

Support Blood Pressure

A growing amount of research suggests nitric oxide can lower blood pressure. When your blood pressure is high, your body’s capacity to use nitric oxide is hampered. High blood pressure causes your blood to push harder against your arteries, which can cause heart difficulties, heart disease, and even death. Nitric oxide has been shown in studies to help blood pressure and reduce the risk of heart disease.

Manage Diabetes

Surprisingly, there is evidence that nitric oxide booster pills are linked to diabetes. This study discovered that taking L-arginine boosted nitric oxide synthesis in persons with type 2 diabetes. Increased insulin sensitivity and better blood sugar control were also linked to higher nitric oxide levels. Another study indicated that L-arginine reduced or delayed the advancement of type 2 diabetes, implying that nitric oxide supplements containing L-arginine could help diabetics and pre-diabetics with various symptoms.

Overall, most of the benefits of NO2 supplements tend to stem from their ability to improve blood flow throughout your body. However, in general, NO2 supplements can potentially improve virtually every aspect of your health, given how all of your organs, tissues, and cells need oxygen to function properly. Improving blood flow makes it easier for these cells to get much-needed oxygen.

Best Foods for Nitric Oxide

You don’t necessarily have to take a nitric oxide supplement to improve NO2 levels. Instead, you can adjust your diet to improve NO2 production. Beets and leafy greens are two of the best sources of nitrates that are easily converted into nitric oxide.


There’s a reason red beet supplements are becoming one of the most popular supplements. Beetroot powder and juice are often consumed for their rich nitrate content. In fact, beets are arguably the best food for nitrate content. Several studies have directly linked beet consumption to lower blood pressure, better heart health, improved athletic performance, etc.

Leafy Greens

Next to beets, leafy greens are the best source of nitrates. These nitrates are easily converted into nitric oxide to boost your NO2 levels. Some of the best leafy greens for nitrates on a per-serving basis include broccoli, spinach, lettuce, arugula, and kale. Other decent sources include cabbage, celery, fennel, leeks, parsley, and cucumber.

Other Foods

Beets and leafy greens are considered the two best sources of nitric oxide. However, other foods are also linked to nitric oxide production, including:

  • Garlic
  • Dark chocolate
  • Meats
  • Nuts and seeds
  • Pomegranate
  • Watermelon

Natural Ways to Boost Nitric Oxide Levels

Believe it or not, simple lifestyle changes can greatly impact your nitric oxide levels. Here are some of the few natural ways you can increase your nitric oxide levels:

Consume More Beets & Vegetables

As previously stated, vegetables and beets are high in nitric oxide precursors. You might be able to raise the amount of nitric oxide in your body by ingesting these substances. Vegetables are also high in antioxidants, which help fight free radicals and inflammation that interfere with nitric oxide levels.

Take a Probiotic Supplement

Taking a probiotic supplement can help replenish gut bacteria, allowing your gut to create nitric oxide more easily. Nitric acid is produced in your intestines due to the meals you ingest. When you take a probiotic, your digestive tract’s gut flora is balanced, which can increase your natural nitric oxide production.


Finally, exercise can increase nitric oxide levels. When you complete compound workouts that include several muscle groups at once, nitric oxide production skyrockets. Some of the greatest exercises for producing nitric oxide include deadlifts, squats, bench presses, and similar exercises. According to several research studies, just a few minutes of high-intensity exercise per day can improve heart, brain, and immune system health.

What Science Says About Nitric Oxide Boosters

Nitric Oxide boosting supplements work in various ways to enhance your body’s natural NO2 production. The best products use science-backed ingredients that are proven to increase nitric oxide levels to widen blood vessels and enhance blood flow.

We’ll take a look at the most science-backed ingredients:

Beetroot is a well-known and effective nitric oxide booster supplement component. Researchers discovered a link between beetroot and blood pressure in various studies over the past few decades. Beetroot extract was discovered to relax blood vessels, decreasing blood pressure in patients, thus reducing their risk of heart attacks. In other studies, beetroot has also improved performance and endurance at the gym by interacting with nitric oxide.

Because beetroot is high in nitrates, a precursor to nitric oxide, we now know it works to enhance NO2 levels quickly. The nitrates in beetroot are converted to nitric oxide in your body, which goes through your bloodstream to enlarge blood vessels and promotes various other benefits.

Some nitric oxide booster products directly increase blood flow without elevating nitric oxide levels. Yohimbine, for example, is a well-known pre-workout supplement component that appears to improve blood flow. Yohimbine was found to promote fat loss, boost energy, and increase blood flow in a 2006 study, making it an effective pre-workout and nitric oxide booster-like ingredient. However, it still doesn’t actually increase nitric oxide levels directly the way beetroot does.

Many nitric oxide booster products contain L-citrulline, an important amino acid. Researchers discovered that increasing nitric oxide generation with L-citrulline could help treat erectile dysfunction in men suffering from mild to severe ED. This is because nitric oxide is required to relax penile muscles to obtain and maintain an erection.

L-citrulline has also been associated with reduced muscular soreness in other studies. For example, researchers gave participants 8 grams of citrulline malate in one study and found the citrulline group had much less muscle discomfort than those who took a placebo.

As one of the most well-studied natural ingredients for NO2 production, L-citrulline has also been found to improve nutrition delivery and eliminate waste products after exercising, all of which can help you recover faster after you work out.

L-arginine is a common element in nitric oxide booster supplements. In fact, it might be the most common ingredient added. It’s also one of the most researched nitric oxide boosters. Many people use arginine because it is a precursor to nitric oxide. Although some arginine is broken down when converted to NO2, taking arginine is a proven way to increase nitric oxide levels. However, citrulline is still considered slightly more effective.

Garlic is more widely used for its immunity and digestive benefits, but it can also enhance blood flow. Some clinical research suggests a direct link between garlic and nitric oxide. In fact, in a study from 1995, researchers found that garlic effectively enhanced the synthesis of NO2 levels, widened blood vessels, and relaxed arteries. An even more promising study found garlic extract boosted nitric oxide levels by 30 to 40% in a short period after ingestion.

Dark chocolate is a simple, tasty way to increase nitric oxide levels. Nitric oxide has been linked to dark chocolate consumption in several studies. Dark chocolate, for example, was found to boost nitric oxide serum levels and reduce blood pressure in patients with prehypertension in a study from 2011. In the study, researchers gave a group 25g of dark chocolate or a placebo and saw significant increases in nitric oxide and blood pressure decreases in the dark chocolate group.

Because nitric oxide has antioxidant properties, several nitric oxide supplements include antioxidants to enhance the effects. Turmeric, green tea leaf extract, and grape seed extract are commonly added to NO2 supplements to amplify the effects quickly.

Overall, there are numerous ways to boost your nitric oxide levels and widen your blood vessels. The best NO2 supplements to reliable raise NO2 levels in your bloodstream to support whatever goal you may have.

Side Effects of Nitric Oxide Boosters

Nitric oxide booster supplements are generally safe for most healthy adults when taken in the recommended dosages.

However, you may encounter negative effects if you exceed the recommended dosage. According to studies, people who consume more than 10g of L-arginine may experience stomach pain and diarrhea.

If your nitric oxide booster pill contains beetroot extract, your urine or stool may turn crimson or dark red. Don’t be alarmed: this is just the beetroot’s natural color leaving your body, and it’s a completely harmless side effect.

In general, though, NO2 boosters are safe and should not cause any negative side effects. If you have a medical condition or are on prescription medication, consult your doctor before trying an NO2 booster.

Recommended Dose of Nitric Oxide Boosters

There is no single “proper” dose of nitric oxide boosters because they include different substances in different amounts. However, some ingredients have recommended dosages.

For example, L-arginine and L-citrulline studies, on the other hand, used dosages ranging from 1 to 10 grams. This was both safe & effective.

Meanwhile, some best-rated beetroot extract products employ 500mg to 2,000mg per serving.
