Nitric oxide (NO) is a vital molecule that your body produces to support healthy circulation and cardiovascular function. Composed of one nitrogen atom and one oxygen atom, nitric oxide plays a key role in vasodilation—the relaxation and widening of blood vessels. This helps improve the flow of blood, oxygen, and nutrients to every part of the body.
Low nitric oxide levels have been linked to serious health concerns like high blood pressure, heart disease, type 2 diabetes, and erectile dysfunction. Fortunately, there are natural, research-backed ways to boost nitric oxide production safely and effectively.
Let’s explore five simple and natural strategies to enhance nitric oxide levels in your body.
1. Eat Nitrate-Rich Vegetables
Vegetables are a top source of natural nitrates, which the body converts into nitric oxide. Some of the best nitrate-rich vegetables include:
-
Celery
-
Lettuce
-
Parsley
-
Cress
-
Arugula
-
Spinach
-
Beetroot
When digested, nitrates are transformed into nitric oxide, which helps support heart health and improves blood flow and athletic performance. Studies show that regular consumption of vegetables like beets can lower blood pressure and increase stamina—comparable to the effects of some medications.
So if you're looking to boost nitric oxide naturally, adding more leafy greens and beets to your plate is a great place to start.
2. Increase Your Antioxidant Intake
Because nitric oxide is unstable and breaks down quickly in the bloodstream, it needs support from antioxidants to stay active. Antioxidants help protect nitric oxide from free radicals, allowing it to circulate longer and do its job more effectively.
Some of the most important nitric oxide-friendly antioxidants include:
-
Vitamin C – Found in citrus fruits, bell peppers, and strawberries
-
Vitamin E – Found in nuts, seeds, and leafy greens
-
Polyphenols – Found in berries, grapes, tea, and cocoa
-
Glutathione – Known as the body’s “master antioxidant”
Many of the same vegetables that are rich in nitrates are also high in antioxidants, making them doubly beneficial for nitric oxide support. A well-balanced diet full of colorful plant-based foods is one of the most effective ways to keep your NO levels healthy.
3. Try Nitric Oxide-Boosting Supplements
If you're looking for an extra boost, certain supplements can help your body produce more nitric oxide naturally. Two of the most popular ingredients are L-arginine and L-citrulline, which are amino acids that play a direct role in the NO production process.
L-arginine converts into nitric oxide through a well-established biochemical pathway. It has been shown to support better blood flow and lower blood pressure, especially in people with cardiovascular risk factors. L-citrulline is converted into L-arginine in the kidneys, and research suggests it may actually be more effective than L-arginine at raising blood levels of nitric oxide.
Looking for an easy and effective supplement to support your nitric oxide levels?
Nitric Boost is a convenient daily supplement designed to naturally enhance nitric oxide production using a synergistic formula of L-arginine, L-citrulline, beetroot extract, and essential vitamins like C, B12, D3, plus magnesium and zinc.

4. Go Easy on Mouthwash
It might sound surprising, but using mouthwash too often can actually reduce your body’s ability to produce nitric oxide.
Here’s why: beneficial bacteria in your mouth help convert nitrates from food into nitric oxide. When you use antibacterial mouthwash, you wipe out these helpful microbes, which can reduce NO production for up to 12 hours.
This drop in nitric oxide levels has even been linked to increased blood pressure and, in some cases, insulin resistance.
To keep your NO levels in check, consider limiting your use of strong mouthwashes or switching to a more natural, microbiome-friendly oral rinse.
5. Exercise Regularly
Physical activity is one of the most reliable ways to increase nitric oxide production. Exercise stimulates your endothelial cells (the cells lining your blood vessels) to produce more NO, which in turn improves circulation and supports heart health.
Both aerobic and strength-based workouts are beneficial. Try incorporating activities like:
-
Brisk walking
-
Cycling
-
Swimming
-
Resistance training
-
Squats or bodyweight movements
Even 30 minutes of moderate exercise three times per week can improve nitric oxide levels over time. And the more consistent your workouts, the stronger the cardiovascular benefits.
Final Thoughts
Nitric oxide plays a critical role in maintaining cardiovascular health, blood pressure balance, and full-body vitality. Fortunately, you can support your body’s nitric oxide levels through smart lifestyle choices:
✅ Eat nitrate-rich vegetables
✅ Load up on antioxidants
✅ Limit harsh mouthwash
✅ Stay active
✅ Consider a high-quality nitric oxide supplement like Nitric Boost
If you're looking for a simple, natural way to feel more energized and support your heart health, boosting your nitric oxide production is a great place to begin.
