What does the term nitric oxide bring to your mind? Probably a gas; and yes NO can occur in that form. But when nitric oxide or nitrogen monoxide is mentioned in relation to the human body, the term refers to the molecule or ion produced in the body to support different functions including the following:

  • Regulate blood pressure
  • Increase blood flow by dilating arteries including those within the male sexual organ
  • Improve endurance and strength
  • Reduce inflammation
  • Enhance memory by acting as an information transmitter between nerve cells within the brain
  • Immune system functions in fighting harmful bacteria
  • Improve quality of sleep
  • Support gastrointestinal motility

What Is The Source Of Nitric Oxide In The Body?

Nitric oxide is synthesized in various tissues such as blood vessels, and muscles. To produce nitrogen oxide, the body uses an amino acid called L-arginine, which is obtained from food sources like nuts, beef, and dairy. Significant amounts of NO are produced by cells in the endothelium (inner arterial walls)

Once produced, nitric oxide helps to maintain stable blood flow throughout the body by relaxing blood vessels so that they dilate and carry more blood to where it is required.

Through this activity, NO supports the supply of oxygen, glucose and other nutrients to body tissues and organs. In addition to its support of the functions of the immune and nervous systems as well as improved stamina and strength, nitrogen oxide is an important player in the improvement and maintenance of healthy sex. It is for this reason that NO is regarded as a key player in achieving and maintaining effective erections. It follows that if your body produces all the nitrogen monoxide it requires, you will be healthy and enjoy a healthy sex life.

But this is not always the case due to reasons such as dietary deficiencies, poor digestion and assimilation, and formation of plaque on the inside walls of the arteries. When this happens, you get health issues including hypertension, poor erection and poor sexual performance.

Signs of Nitric oxide Deficiency

If you have the following symptoms, you might have nitric oxide deficiency:

  • Erectile dysfunction
  • Chronic fatigue
  • Physical weakness
  • Chronic kidney disease
  • High blood pressure
  • Psoriasis
  • low testosterone

But nitric oxide deficiency does not mean that all is lost. And although, you may have tried to remedy the situation by eating all those foods that are supposed to help your body produce enough nitric oxide to no avail, there is still hope.

Nitric Oxide Supplements for Better Erections

The good news is; there is another way to support your body so that it produces all the NO necessary to pump blood to where it is needed most. Hundreds of studies have been conducted on the subject of nitric oxide. These have led to the identification of specific natural supplements that can help to increase nitric acid production in your body and thereby help you live a normal life.

Supplements that increase production of nitric oxide in your body can help you get more effective erections and by so doing, banish your erectile dysfunction. This is similar to how ED drugs such as Viagra work. The difference is that by relying on natural supplements, you support your sexual functions without the risk of dangerous side effects. Let us now look at 10 supplements that increase nitric oxide production.

10 Supplements That Increase Nitric Oxide Production

   Omega-3 Fatty Acids

Omega-3 fatty acids protect the body from inflammation besides increasing the production of nitric oxide. This leads to improved circulatory health including normal blood pressure and reduced risk of stroke and heart disease. Omega-3 is normally obtained from dietary sources and is abundant in fatty fish. However, the modern diet contains too much omega-6 and minimal omega-3, a situation that exposes the body to inflammation, high blood pressure and weak erections. Taking omega-3 fatty acids supplements can remedy these conditions and lead to better erections and sexual health.



Resveratrol, a polyphenol flavonoid, occurs naturally in grapes and is also found in red wine. Studies indicate that resveratrol increases the production of NO by stimulating the nitric oxide synthase enzyme. Supplementing with resveratrol also boosts testosterone levels while lowering estrogen levels. These properties make it an important sexual health enhancer which improves erection.


Icariin is extracted from epimedium (horny goat weed), a herb with a history of use as an aphrodisiac. Icariin works by increasing production of nitric oxide besides acting as an inhibitor of the PDE-5 enzyme in a similar way to conventional ED drugs. Additionally, icariin boosts testosterone levels and is, therefore, a natural anti-ED supplement that also improves blood circulation and nerve growth in the pelvic region.


Niacin, also known as vitamin B3, is an essential vitamin in the human body. Energy production, hormone synthesis and gene expression are some of the roles in which niacin is involved. It also protects the heart and supports the cardiovascular system through its involvement in nitric oxide synthesis. Other roles include increasing HDL (good cholesterol) levels and lowering LDL (bad cholesterol) levels, and reducing inflammation. By supporting NO production and cardiovascular health, niacin helps improve sexual prowess. Regular supplementation with vitamin B3 has been shown to improve erections, especially for individuals with high cholesterol.



Pycnogenol is an extract from the bark of the French maritime pine tree and is a rich source of an antioxidant called anthocyanin that supports the activities of L-arginine. It also contains bioflavonoids like taxifolin and catechin. According to various studies, pycnogenol supplementation increases the production of NO within the endothelium, thereby helping to achieve functional erections besides improving general cardiovascular integrity. One study established that taking 40 to 120 mg of pycnogenol leads to significant improvement of erections in men with erectile dysfunction. The subjects were able to achieve and maintain functional erections.


Arginine is an amino acid from which nitric oxide is synthesized within the body. It is, therefore, a precursor to nitric oxide. By supporting the production of NO, arginine supplements help improve sexual health, besides reducing inflammation and improving overall cardiovascular health.

Nutricost L-Citrulline Malate

L-citrulline is an amino acid that is produced within the body as a by-product when nitric oxide synthases enzymes synthesize the amino acid, L-arginine to produce nitric oxide. L-citruline is thereafter synthesized in the kidneys back to L-arginine and the cycle continues. Taking L-citruline supplements provides your body with more raw materials for the synthesis of L-arginine from which more nitric oxide is produced. Studies indicate that supplementing with L-citruline is more effective than supplementing with L-arginine directly.

Vitamin C

Vitamin C in an important vitamin involved in maintaining overall health and supporting healing. It also increases production of nitric oxide besides protecting the NO molecules within the body. Studies indicate that vitamin C supplements can help increase NO production thereby improving blood circulation including increased blood flow within the sexual organ.

Korean red Ginseng

Korean ginseng has been used as an aphrodisiac for hundreds of years and recent studies have confirmed its efficacy. One study showed that using ginseng supplementation for a few weeks helps improve sexual prowess, including achieving harder erections that last longer. Ginseng works by increasing testosterone levels, thereby improving libido. It also boosts the production of dopamine in the brain, and promotes the production of nitric oxide within the penis.

Coenzyme Q10

Coenzyme Q10 molecules are found in the mitochondria within cells where it is involved in energy production. It helps increase nitric oxide production. In normal circumstances, coenzyme Q10 is synthesized in the body. But when the body is unable to produce adequate amounts of coenzyme 10, conditions like low testosterone, infertility, fibromyalgia, cardiovascular disease, and Parkinson’s disease can arise. Taking coenzyme Q10 supplements helps your body to produce sufficient nitric oxide in addition to protecting the NO molecules. These properties support cardiovascular health and improve sexual potency.


Being nitric oxide deficient is not a sentence to low libido as you can remedy the condition by eating a healthy diet and taking supplements that increase production of nitric oxide in your body. And if you have any medical condition and wish to take supplements for increased nitric oxide, consult a healthcare professional for advice.
