If you’ve been in the fitness industry for any length of time, you should know all about nitric oxide and the advantages of increasing nitric oxide levels — especially as it relates to helping induce insane muscle pumps that leave you doing a double-take in the gym mirror as you pass by.
What many fail to realize is that increasing nitric oxide levels serves many purposes other than making your muscles look freakishly big. Nitric oxide actually serves numerous vital functions in the body and offers notable advantages for vascular and heart health, among other things.
So, how can you ensure an adequate intake of this crucial nutrient all day to help maximize the benefits?
In this article, we will dive deeper into nitric oxide and how you can add certain healthy foods to your daily nutrition to help skyrocket nitric oxide levels.

What is Nitric Oxide and Why Should You Care?
Your body uses nitric oxide to help regulate various functions, even though, technically, it is considered a free radical.
Our body needs to create nitric oxide out of component parts, which include nitrates and vitamin C. Without enough of these component parts, you won’t be able to make enough nitric oxide. This would impact many systems in the body, including the following:
- Circulatory System: Nitric oxide plays a significant role in regulating the dilation and constriction of blood vessels in the body. By doing so, it has the potential to improve blood pressure, ultimately benefiting heart health.
- Immune System: The immune system is a complex network consisting of diverse cell types. Nitric oxide aids in facilitating communication and promoting swift responses among these cells when encountering pathogens or foreign invaders.
- Exercise and Muscle Performance: Nitric oxide may contribute to improved physical performance, as athletes receiving nitrate supplements showed increased endurance and delayed fatigue. Boosting nitric oxide levels through dietary nitrate intake can potentially enhance exercise performance.
Discover These 7 Healthy Foods That Enhance Nitric Oxide Levels
Including foods that are naturally high in nitrates in your diet can be a simple and effective way to enhance your nitric oxide levels. Below are seven nutrient-rich foods that are abundant in natural nitrates.
1. Beets
Beets are rich in dietary nitrates, which our body can change to nitric oxide. According to a study of 38 adults, consuming a beetroot juice supplement increased nitric oxide levels by 21% after only 45 minutes.
In the same way, another study showed that drinking 100 ml (3.4 ounces) of beetroot juice majorly increased nitric oxide levels in both women and men. Due to their rich content of dietary nitrates, beetroot has been linked to various health benefits, including improved athletic performance, enhanced cognitive function, and decreased blood pressure levels.
2. Garlic
Garlic and various other phytonutrients offer cardiovascular health benefits and help prevent heart disease. One of the ways they achieve this is by enhancing the production of nitric oxide. By activating the enzyme nitric oxide synthase, they facilitate the conversion of L-arginine into nitric oxide.
Combining garlic with arginine supplements can provide an additional boost to nitric oxide activity.
3. Meat
Meat, seafood, and poultry are all great sources of coenzyme Q10, or CoQ10, which is an important compound to help preserve nitric oxide in our bodies. Organ meats, fatty fish, and muscle meats such as beef, chicken, and pork are rich sources of CoQ10, with the highest concentrations.
Research indicates that maintaining sufficient levels of CoQ10 in your diet not only helps preserve nitric oxide but also has potential benefits for athletic performance, migraine prevention, and overall heart health.
4. Dark Chocolate
Cocoa, with its abundance of flavonols, provides valuable protection against oxidative stress, acting as potent antioxidants that help preserve endothelial function.
Research indicates that flavanols in cocoa can play a crucial role in maintaining optimal levels of nitric oxide in the body, thereby supporting heart health and protecting against oxidative damage to cells.
5. Leafy Greens
Leafy green vegetables like arugula, kale, spinach, and cabbage are packed with nitrates, which are converted to nitric oxide in our bodies.
According to one review, regularly consuming nitrate-rich foods such as green leafy vegetables can help maintain enough nitric oxide levels in the tissues and blood.
One study even showed that consuming nitrate-rich meals containing spinach increased salivary nitrate levels eightfold and majorly decreased systolic blood pressure.
6. Pomegranate
Pomegranate contains potent antioxidants that can protect our cells against damage and preserve nitric oxide.
In a test-tube study, it was observed that pomegranate juice demonstrated effectiveness in safeguarding nitric oxide from oxidative damage and simultaneously enhancing its activity.
Another animal study found that both pomegranate fruit extract and pomegranate juice were able to increase levels of nitric oxide synthase and enhance the concentration of nitrates in the blood.
7. Citrus fruits
Citrus fruits such as oranges, lemons, limes, and grapefruits are rich sources of vitamin C, a crucial water-soluble vitamin known for its vital role in maintaining overall health. Vitamin C can improve nitric oxide levels by enhancing its bioavailability and maximizing absorption within the body.
Furthermore, research suggests that it can also elevate levels of nitric oxide synthase, the enzyme essential for producing nitric oxide.
