Top 12 Best Foods To Boost Nitric Oxide Levels

Nitric oxide is a gas molecule in the body responsible for blood pressure regulation, reproduction, and protecting the cardiovascular and immune systems. 


Therapeutically, nitric oxide is used as a supplement to combat sexual disorders like erectile dysfunction and infertility. It’s also popular with athletes for its ability to enhance training performance, reduce fatigue, increase muscle size and promote recovery.

Whether in food or supplement form, adding nitric oxide to your diet can increase your energy levels, giving you an extra boost to conquer your busy schedule and survive the toughest workouts.


What is Nitric Oxide?


Nitric oxide circulates oxygen, nutrients, and blood through the body. It improves metabolic health and cognitive functions and increases sexual stamina and muscle hypertrophy. 


External nitric oxide is found in foods like meats, fruits, dark chocolate, and green leafy vegetables. Eating nitric oxide-rich foods can lower blood pressure and relax constricted veins and arteries. Our bodies produce nitric oxide with the help of the enzyme nitric oxide synthase.


In recent years, nitric oxide supplements have grown in popularity in the fitness community. 


Athletes use it to increase energy, improve training performance, and increase muscle repair. This allows athletes to train longer and harder, with less downtime recovering. Supplementing with nitric oxide can provide many benefits, but reviews are mixed about the effects of long-term use. 


Next, you’ll learn how nitric oxide is created and functions in the body. 


Nitric Oxide Production in the Body

Nitric oxide is a gas made from the amino acid L-arginine combined with oxygen. It's an anti-bacterial and anti-inflammatory molecule that lines every organ and tissue in the body.


As a biological regulator, nitric oxide works as a messenger, moving blood, oxygen, and nutrients throughout the body. It controls the functioning process of the circulatory, respiratory, digestive, and immune systems. Nitric oxide is used to treat metabolic conditions like coronary heart disease and myocardial infarctions (heart attacks).


In 2018, the National Institute of Diabetes and Digestive and Kidney Disorders cited nitric oxide as providing therapeutic benefits to the cardiovascular and renal systems and metabolic conditions like hypertension. 


In reproduction, nitric oxide is used to treat sexual disorders and prevent fertility issues. For men, it is used to treat erectile dysfunction by relaxing the smooth muscles and allowing blood to circulate to the genitals. This has been found to prolong erections and improve sexual performance. 


For women, studies show that nitric oxide is beneficial in encouraging ovulation, regulating menstruation, and preventing reproductive diseases. 


In the fitness world, nutrition companies sell nitric oxide supplements as a strength and endurance enhancer. These supplements don't contain the molecule. Instead, they contain substrates that encourage nitric oxide production in the body. All natural athletes can consume nitric oxide-rich foods to improve levels and performance.  


Health Benefits of Nitric Oxide Foods

Nitrates and nitrites are compounds naturally found in soil and water. They are also used in the food industry as additives in cured meats like ham, bacon, deli meats, and hot dogs to preserve smell, meat color, and flavor. Some people avoid foods that contain nitrates due to negative effects like high sodium and the promotion of gastric, prostate, and breast cancer.


A 2021 study found that cured meats with high nitric oxide levels can cause colon cancer. But plant-based extracts can serve as an equivalent alternative for meat preservation. 


Healthy nitrates are in vegetables like beats, dark leafy greens (i.e., kale, spinach, etc.), nuts, and fruits. Consuming these nitro oxide-rich foods promotes blood circulation, lowers blood pressure, and improves heart health and reduces the risk of cardiovascular disease.

Increased Blood Flow & Improved Cardiovascular Health


Nitric oxide plays an important role in cell communication for the central nervous system. It moderates seizures, cerebral diseases like strokes, and neurological disorders like Alzheimer's. 

Increased Energy Levels


Nitric oxide improves blood flow and vessel health by promoting metabolic efficiency and the production of oxygen diffusion.

Improved Athletic Performance


Nitric oxide supplements are known to have a positive effect on athletic performance by widening blood vessels during exercise. Blood, oxygen, and nutrients can easily travel to the muscles improving protein synthesis and repair

Reduce Blood Pressure


Nitric oxide improves blood flow and vessel health by promoting blood circulation to muscles throughout the body. 

Improved Brain Function


Nitric oxide works as a neurotransmitter to improve brain function by increasing cerebral blood flow which allows for messages to be sent from cells in the body to the brain. 


Next, we'll look at 12 foods that can help promote positive nitric oxide levels and improve performance in the gym, in between the sheets, and in everyday life.
