How To Naturally Increase Nitric Oxide?- 7 Ways Explained!


Nitric oxide is a small, gaseous signaling molecule produced by almost every type of cell in the human body. It’s a key player in various physiological processes.

Primarily, nitric oxide is synthesized from the amino acid L-arginine by a group of enzymes known as nitric oxide synthases (NOS). It’s unique for being a gas that acts as a signal in a biological system.

It is best known for its role in regulating blood flow and blood pressure. It relaxes the inner muscles of the blood vessels as well. In this article, we will discuss the natural ways to nitric oxide. Let’s check it out!

What Are The Natural Ways To Boost Nitric Oxide? – Everyone Must Know

Furthermore, we have listed a few ways to increase nitric oxide in your body naturally:

Natural Ways To Boost Nitric Oxide

Dietary methods to boost nitric oxide

One effective way to naturally increase nitric oxide levels in the body is through diet, particularly by consuming foods rich in nitrates and antioxidants.

Vegetables like beet, kale, and arugula are excellent sources of dietary nitrates. Beets, in particular, stand out for their high nitrate content. These nitrates are converted into nitric oxide in the body, enhancing blood flow and lowering blood pressure. 

In addition to nitrates, antioxidants are crucial in nitric acid production. Foods rich in antioxidants, such as berries and dark chocolate, help protect nitric oxide from being destroyed by oxidative stress. 

Exercise and nitric acid production

Exercise is another key factor in enhancing nitric oxide production. Various forms of physical activity, such as aerobic exercises, strength training, and high-intensity interval training (HIIT), can significantly boost nitric oxide levels.

Aerobic exercises like jogging, cycling, and swimming increase heart rate and blood flow, stimulating the production of nitric oxide.

Additionally, exercise helps prevent the development of atherosclerosis, a key factor in many cardiovascular diseases, by maintaining high levels of nitric oxide, vital for vascular health and the prevention of cardiovascular conditions. 

Sunlight and Nitric Oxide

When the skin is exposed to sunlight, particularly UV rays, it can stimulate the release of nitric oxide stored in the skin into the bloodstream. This process leads to vasodilation, the widening of blood vessels, which improves blood flow and lower blood pressure.

Moreover, the enhanced nitric oxide levels due to sunlight exposure aid in reducing the risk of certain heart conditions. However, while sunlight exposure has certain health benefits, it’s important to practice safe sunlight exposure to avoid the risks associated with UV radiation, such as skin cancer. 

Supplements for nitric oxide increase

L-arginine is an amino acid that serves as a direct precursor to nitric acid. The body converts L-arginine into nitric oxide through the action of nitric oxide synthase enzymes.

Supplementing with L-arginine has been shown to improve blood flow and vasodilation. It is especially beneficial for people with cardiovascular issues or those looking to enhance exercise performance. 

L-citrulline is another amino acid that plays a crucial role in producing nitric oxide. The body transforms L-citrulline into L-arginine, which is then utilized to create nitric oxide.

Some studies suggest that L-citrulline may be more effective than L-arginine because it provides a long-lasting increase in L-arginine levels and, consequently, in nitric oxide production. 

Lifestyle factors

The production of nitric oxide in the body is significantly influenced by lifestyle factors such as sleep and stress. Chronic stress can impair the body’s ability to produce nitric oxide.

This reduction in nitric oxide can lead to compromised blood flow and vascular health. On the other hand, quality sleep plays a prominent role in maintaining optimal nitric oxide levels.

During sleep, the body engages in various restorative processes, including the regulation of nitric oxide production. These processes can be disturbed by sleep deprivation or poor sleep quality. Therefore, it’s crucial to practice techniques such as yoga, meditation, and physical activities. 

Maintaining good oral hygiene

An often overlooked method to increase nitric oxide is maintaining good oral hygiene. The connection between oral health and nitric oxide production lies in the bacteria found in the mouth.

These oral bacteria play a vital role in converting dietary nitrates (from nitrate-rich foods) into nitrites, which are then converted into nitric oxide when they enter the body.

When oral hygiene is poor, the balance of these beneficial bacteria can be disrupted. This reduces the conversion of nitrates to nitrites. Regular brushing, flossing, and routine dental checkups help maintain a healthy oral microbiome. You can also use mouthwash that is not overly harsh. 

 Other natural methods

Breathing exercises play a crucial role in nitric oxide production. Deep and rhythmic breathing, especially through the nasal passage, can increase the release of nitric oxide into the bloodstream.

Techniques like diaphragmatic breathing, pranayama from yogic practices, and Buteyko breathing are particularly effective in enhancing nitric oxide levels. 

Herbal remedies and traditional practices also contribute to nitric oxide levels. Herbs, such as Hawthorn, Ginseng, and Ginkgo Biloba, traditionally used for improving blood flow and cardiovascular health, can impact nitric oxide synthesis.

Moreover, practices like acupuncture and certain massage therapies can indirectly influence nitric oxide levels by improving blood circulation and reducing stress. 


In conclusion, boosting nitric oxide levels naturally encompasses a variety of strategies, ranging from dietary choices to lifestyle adjustments. This holistic approach to naturally increasing nitric oxide highlights the importance of a blanched lifestyle.

It’s not just about what we eat or how we exercise but also how we manage stress, sleep, and even maintain oral health. By adopting the above-mentioned methods, individuals can significantly improve their nitric oxide levels, leading to better health outcomes, improved cardiovascular function, and enhanced overall wellness.

However, it’s important to note that you must consult a healthcare professional when considering changes in your diet or adding supplements to your daily routine.
