I am totally satisfied with this product. I am a 53-year-old man that works out for about an hour, 3-4 days a week. My body has totally improved and it happened quickly. I look better than I did when I was in high school. I recommend this product to anyone looking for a supplement for weight training. I would say though, I also changed my diet and eat much more protein and healthy foods than I used to. Read more Read less

Our Secret

The Secret To Our Successful Supplement Is A High Dosage Of L-Arginine:

L-Arginine is a powerful amino acid that helps the body to build protein. Additionally, the body converts L-Arginine into Nitric Oxide, increasing blood flow, boosting oxygen supply, and promoting lean muscle growth. Our Nitric Oxide supplement boasts 1680mg of L-Arginine in a clinically-proven complex that helps improve muscle strength and growth, enhance athletic performance, and aid post-workout recovery.

The Secret To Our Successful Supplement Is A High Dosage Of L-Arginine:

What's In Research Verified Nitric Oxide?

Nitric-X™ L-Arginine Blend

Our exclusive, trademarked blend contains L-Arginine - an amino acid and the precursor for the synthesis of Nitric Oxide. This formula offers a powerful blend of four forms of L-Arginine (AAKG, AKIC, Mono, and Malate) to act as the optimum agents in the metabolism of Nitric Oxide production.


An important vasodilator essential for regulating blood pressure, relaxing muscles in blood vessel walls, and promoting blood flow. This amino acid has also been shown to boost energy, reduce muscle fatigue, and promote endurance.


Quercetin possesses powerful antioxidant, antiviral, and antihistamine qualities that increase the biological activity of Nitric Oxide and boost energy production.

Eurycoma Longifolia Extract

This plant extract contains testosterone-boosting properties that can promote athletic performance, increase overall endurance, support mental focus, as well as reduce body fat.

Pine Bark Extract

Pine Bark has the ability to increase Nitric Oxide production by boosting blood circulation and flow, inducing blood vessel relaxation, and promoting oxygen supply to the muscles. Ultimately, this special extract can enhance endurance for a longer workout and faster recovery.


BioPerine® is a patented black pepper extract that improves nutrient absorption. Piperine is the main alkaloid from black pepper and has been shown to substantially increase the bioavailability of the nutrients in foods and supplements. Piperine can turn a marginally effective therapeutic substance into a highly effective one by increasing its bioavailability and intracellular residency time.

How do Nitric Oxide supplements work?

Nitric Oxide is produced by the body and is essential for delivering messages between the body’s cells. Nitric Oxide plays a key role in causing blood vessel vasodilation to increase blood flow, boosting the delivery of oxygen and essential nutrients to the muscles, as well as promoting growth and bulk. The amino acids L-Arginine and L-Citrulline are precursors to Nitric Oxide production. These amino acids promote the ultimate Nitric Oxide boost to increase the flow of blood that pumps valuable oxygen and nutrients to muscles, stimulating growth. Additionally, they facilitate the removal of exercise-induced lactic acid buildup, which in turn reduces fatigue, boosts endurance, and aids post-workout recovery. This supplement does things that other bodybuilding supplements simply can’t, by working on two fronts. First, it increases levels of oxygen and nutrients in the blood, boosting lean muscle growth. Second, it sustains energy levels during workouts and speeds up post-workout recovery, so you can exercise more frequently for longer periods of time.

How quickly should I see results?

Some customers report seeing results in as little as one week. For others, it took about a month. Results will be a bit different for each person. Some show unbelievable change right away, while others take longer.

What is the recommended dosage?

On workout days: Take 3 capsules in the mornings before breakfast and 3 capsules 30 minutes before a workout. On rest days: Take three capsules in the mornings before breakfast and 3 capsules in the evenings before dinner. As with any type of supplement, you should not exceed the daily dosage recommendations since this can pose health risks.

Is Research Verified® Nitric Oxide vegan?

Yes, Research Verified® Nitric Oxide is completely vegan and cruelty-free.

Can I safely order over the internet?

Yes, with Research Verified® your credit card information is private and we guarantee that you won’t be enrolled in any “automatic billing” programs. Other companies may engage in shady business practices, including automatic billing. These programs will repeatedly charge your credit card, sometimes without your knowledge. Research Verified products are safe to order online, and it also ships quickly and discreetly.

Are there any side effects to watch out for?

We always recommend consulting with a physician if you have a medical condition or take medications on a regular basis. Also, pregnant or nursing women are advised not to take Nitric Oxide.

What is the return policy?

We are so confident that this product is going to work that we offer a full one-year guarantee. If at any time you are unsatisfied with a product you purchased from us, you may return any opened and unopened bottles within 365 days of the purchase date for a full refund, excluding shipping.
