Best Nitric Oxide Supplements 2024: Top Recommendations

Nitric oxide (NO) is a naturally occurring molecule in the human body that is involved in various physiological processes, including vasodilation — widening of blood vessels to improve blood flow.

This proposed increase in blood flow is suggested to deliver a host of benefits, including reduced erectile dysfunction (ED), enhanced physical performance, and improvement of cardiovascular health. However, where it gets interesting is understanding how supplementing with nitric oxide actually works, as unlike containing the molecule itself, these supplements typically include precursors that the body uses for nitric oxide production.

In this article, we will guide you through the complex details surrounding nitric oxide products and their formulations. We will explore the science behind them and provide our recommendations for the best nitric oxide supplements available today.

Several supplements on our list may contain ingredients for which evidence is derived primarily from cell and animal model studies or limited human clinical trials. While these initial studies suggest potential beneficial health effects, it is important to note that more robust human studies are required to establish the effectiveness and safety of these ingredients conclusively. Individual responses to these ingredients may vary, and caution is advised. Before incorporating these dietary supplements into your routine, especially if you have underlying health conditions or are pregnant, nursing, or taking medications, it is crucial to consult with a healthcare professional.

The science behind nitric oxide boosters

Nitric oxide boosters function by increasing the production of nitric oxide in the body. These boosters primarily affect two physiological pathways: the nitric oxide synthase (NOS)-dependent and NOS-independent pathways.

In the context of the NOS-dependent pathway, it is heavily influenced by the amino acids L-arginine and L-citrulline. While L-arginine is converted to NO via the action of NOS enzymes, L-citrulline acts as a secondary contributor to NO production since it can be converted to L-arginine.

As for the NOS-independent pathway, it is often activated by dietary nitrate present in foods such as beetroot, spinach, arugula, dairy, and meat.

The end result of both pathways is an increase in NO levels, which leads to vasodilation — or the widening of blood vessels. This expansion facilitates improved blood flow, supporting a more efficient delivery of oxygen and nutrients to tissues, including muscles. These effects are associated with a sea of benefits, some of which we touch upon in the paragraphs below.

Benefits of nitric oxide supplements for erectile dysfunction

Erectile dysfunction is a common condition characterized by the inability to achieve or maintain a penile erection sufficient for satisfactory sexual performance. While research on nitric oxide supplements for ED is still ongoing, it has been suggested that increasing nitric oxide levels may offer potential benefits for those with ED.

In theory, the primary proposed benefit of NO supplementation lies in the vasodilatory effects of nitric oxide, which facilitate blood flow to the genital area. This improved circulation is crucial for achieving and sustaining an erection.

According to this clinical trial, supplementation with relatively high doses of L-arginine — a well-researched NO booster — demonstrated a significant improvement in penile erectile function for patients with vasculogenic erectile dysfunction over a 3-month period.

In contrast, in this single-blind study with humans, oral L-citrulline, another key component associated with NO production, was shown to improve erection hardness in men experiencing mild ED.

While the current body of evidence for nitric oxide supplements is promising, it is of great importance to approach these supplements with caution, as the scientific evidence supporting their efficacy for treating ED is still emerging.

Exploring the benefits of nitric oxide supplements for overall health

The benefits associated with nitric oxide supplementation range beyond specific conditions such as ED. By supporting blood vessel function and optimizing blood flow, NO boosters have demonstrated potential both in exercise performance and cardiovascular health.

When talking about exercise performance, it is thought that nitric oxide supplementation could potentially enhance athletic performance by increasing oxygen and nutrient delivery to the muscles.

A review of the current literature on strength performance has shown that while there is scant evidence to support the use of L-arginine in enhancing strength performance, L-citrulline and nitrate appear to have beneficial effects on muscular performance.

Now, in regards to cardiovascular health, nitric oxide supplements are suggested to have beneficial effects on the heart, including maintaining healthy blood pressure and supporting efficient blood flow. It should be noted, however, that further long-term well designed human studies are required to validate these effects.

Once again, it is advisable to approach even the best nitric oxide supplements with realistic expectations.

How to choose the best nitric oxide supplements

To find the optimal product that aligns with your preferences and needs, start by asking, 'What is the best nitric oxide supplement?' You may consider the following steps as your guide.

  • Check supplement facts. Take a look at the supplement facts label. Make sure the product includes well-researched ingredients such as L-arginine and L-citrulline. Avoid proprietary blends that may hide individual ingredients and their dosages.
  • Check for allergens and additives. Examine the product's ingredient list for potential allergens or unnecessary additives. Choose supplements with clean formulations that align with your dietary preferences and restrictions.
  • Consider your personal preference. Decide whether you prefer a powder or capsule form. Powders are often mixed with water and consumed as a beverage, while capsules offer convenience. Choose based on your personal preference.
  • Consider the price point. Evaluate products across various price points and try to balance affordability with quality. Choose a supplement that fits your budget while meeting the desired standards of manufacturing and ingredient quality.

Concluding recommendations for best nitric oxide supplements

While the potential of the best nitric oxide supplements in promoting exercise performance, improving cardiovascular health, and aiding with ED is evident and documented, it is imperative to approach these supplements with healthy and reasonable expectations. This is particularly important given that research on their long-term effects and safety is still inconclusive.

It is also worth noting that a balanced diet rich in whole foods, regular exercise, and a healthy lifestyle can contribute to optimal nitric oxide production and levels within the body. Therefore, the best nitric oxide pills should complement, not replace, a well-rounded approach to health and fitness.
