Nerve NO2 Real Review: I Tried it for 30 Days–Does This Nitric Oxide Booster Really Work?

Nerve NO2 is a nitric oxide booster that promotes healthy circulation and muscle growth.

Taking two capsules of Nerve NO2 daily can use a blend of natural ingredients to promote cardiovascular health and support nitric oxide production.

Keep reading to learn everything you need to know about Nerve NO2 and how it works today in our review.

What is Nerve NO2?

Nerve NO2 is a nutritional supplement featuring three amino acids blended to promote cardiovascular and nerve health.

Some take Nerve NO2 to fight tingling in the extremities caused by nerve pain. Others take it to support general heart health and blood flow.

Your body produces nitric oxide (NO) every day. Nitric oxide helps keep blood vessels loose, making blood flow easier throughout your body.

However, your body needs certain building blocks—including amino acids—to produce nitric oxide. Each capsule of Nerve NO2 contains these building blocks, helping to support cardiovascular health.

Nerve NO2 is available exclusively online through GetNerveSavior.com, priced at $59 per bottle and backed by a 60-day money-back guarantee.

  • Support nerve health and nerve repair
  • Made in the United States

How Does Nerve NO2 Work?

Nerve NO2 is primarily designed to support heart health and nerve health. To do that, the supplement focuses specifically on nitric oxide production.

Nitric oxide (NO) is a natural molecule your body produces daily. The more nitric oxide you produce, the more flexible your blood vessels tend to be, making it easier for blood to flow anywhere in your body.

Some nerve and heart health supplements contain dozens of unproven plant extracts at low doses. The makers of Nerve NO2 took a different approach. Each two-capsule serving contains three active ingredients at strong doses, including three amino acids linked to heart and nerve health.

Each of the three amino acids in Nerve NO2 works differently to promote nitric oxide production. They give your body the building blocks needed to produce nitric oxide, helping to promote blood flow, nerve health, and overall cardiovascular health.

Nerve NO2 Ingredients

Each two-capsule serving of Nerve NO2 contains three active ingredients, including three amino acids.

The three active ingredients in Nerve NO2 include:

L-citrulline Malate: One of the best-known amino acids for heart health, L-citrulline is found in everything from pre-workout supplements to heart health formulas. L-citrulline, as WebMD explains, “boosts nitric oxide production in the body,” helping your arteries relax and work better while improving overall blood flow. Some people take L-citrulline daily for blood flow, while others take it with L-arginine (say, in a 2:1 ratio).

Your body naturally produces L-citrulline from your food (it’s naturally present in watermelon, for example), but you can also take it in supplement form. L-citrulline works well with L-arginine because your body converts L-citrulline into L-arginine after ingestion, raising L-arginine levels and promoting blood flow overall.

L-Arginine Hydrochloride: L-arginine hydrochloride is the first of two types of L-arginine within Nerve NO2. Also known as L-arginine HCl, it’s the most popular form of L-arginine used in the supplement space today. L-arginine is an amino acid in red meat, poultry, fish, and dairy. Your body uses L-arginine to make protein. In the supplement world, however, L-arginine is best known for its effects on cardiovascular health and circulation. Some take it daily for blood flow, while others take it before a workout to increase the delivery of oxygen and nutrients throughout the body.

L-Arginine Alpha Ketoglutarate: Also known as AAKG, arginine alpha-ketoglutarate is made by combining L-arginine with alpha-ketoglutarate. It’s a popular bodybuilding supplement ingredient for energy, blood flow, heart health, and more. AAKG, best known as a pre-workout formula, helps energize the body before a workout by providing an easy, fast-acting energy source. Some research suggests it also helps to increase muscle mass and boost overall exercise performance, among other benefits.


How to Take Nerve NO2

Nerve Savior recommends taking two capsules of Nerve NO2 daily to promote heart health and circulation:

  • Take two capsules of Nerve NO2 daily with 6 to 8oz of water

Talk to a healthcare professional before taking Nerve NO2 (or any supplement) if you have a medical condition or are taking medication.

What to Expect After Taking Nerve NO2

According to the manufacturer, Nerve NO2 was designed to promote two specific benefits: healthy circulation and muscle growth:

Healthy Circulation: The primary goal of Nerve NO2, like most nitric oxide booster supplements, is to promote healthy circulation. When your body produces nitric oxide (NO), it helps blood circulate more easily. It reduces the strain on your cardiovascular system, allowing you to support healthy blood pressure. Higher nitric oxide levels are associated with wider, more flexible blood vessels. When your blood vessels are stiff, you tend to have higher blood pressure. By relaxing blood vessels, you can lower blood pressure.

Support Muscle Growth: The three amino acids in Nerve NO2 can also be found in pre-workout and post-workout supplements. Some people take these amino acids to promote muscle growth and development. Others take them to boost energy and blood flow before a workout. The three amino acids aren’t just the building blocks of nitric oxide but also the building blocks of protein, including the protein your body uses to repair muscle after a workout. Taking two capsules of Nerve NO2 daily can promote muscle growth when combined with an active lifestyle.

As the name suggests, Nerve NO2 could also promote nerve health. However, the official website does not specifically mention nerve health, neuropathy, diabetic neuropathy, or other nervous system dysfunction. Nevertheless, promoting blood flow can help supply your nerves with the oxygen and nutrients they need to repair themselves and stay active, helping to fight back against nerve pain.

Scientific Evidence for Nerve NO2

Nerve NO2 contains three science-backed ingredients linked to nerve health, including three amino acids. Multiple studies have shown that all three amino acids promote blood flow and support related benefits.

According to the Cleveland Clinic, L-citrulline may be helpful for athletic performance because it improves blood flow to working muscles, making it easier for the body to perform at peak intensity. This benefit seems particularly important for anaerobic exercises—like strength training—as opposed to aerobic exercises, like running.

In one recent study, researchers gave a group of cyclists L-citrulline or a placebo. Researchers found that those in the L-citrulline group biked faster and stayed energized longer than those in the placebo group. Participants took 2,400mg of L-citrulline daily for eight days before completing the test bike ride.

L-arginine is one of the best-known and most popular supplement ingredients for blood flow; many take it daily for that reason. In a 1998 study published in the British Journal of Clinical Pharmacology, researchers found L-arginine induced vasodilation in healthy humans, helping to widen blood vessels significantly. Participants received a very high dose of L-arginine (30g intravenously or 6g orally), and the study only involved 8 men. However, it suggests arginine could help with blood flow.

Some studies have specifically examined the effects of L-arginine alpha-ketoglutarate (AAKG). In a 2011 study, for example, researchers found taking AAKG for seven days helped with blood flow, L-arginine, nitric oxide production, and other benefits linked to athletic performance. Participants also had higher heart rates, blood pressure, and blood flow.

Some take Nerve NO2 specifically for nerve health and nerve damage. In a 2024 study, researchers found increasing blood flow to nerve-damaged areas could help with nerve injury repair. In that study, researchers found increasing blood flow increased oxygen and nutrient flow to damaged nerves, helping to kickstart the body’s natural repair processes. Poor blood flow to an area, over a long period, can weaken nerve health. By boosting blood flow, you could experience greater results.
