Nitric oxide is a molecule produced in the body that has several health benefits, including improved exercise performance, better brain function, and blood pressure regulation. As we age, the body's ability to produce nitric oxide decreases, which can lead to adverse health effects. However, making a few simple dietary changes can help increase nitric oxide levels. Consuming foods rich in nitrates, such as leafy greens (spinach, kale, arugula), beets, celery, and radishes, can boost nitric oxide production. Additionally, traditional Japanese vegetables, apples, and watermelon are excellent sources of nitrates and flavanoids. Relaxation techniques, such as meditation and deep breathing, can also help increase nitric oxide levels by reducing stress.

What You'll Learn

Eat leafy greens like spinach, kale, arugula, and celery
Eating leafy greens is a great way to increase nitric oxide levels in the body. Nitric oxide has a wide range of health benefits, including improved blood flow, lower blood pressure, and better brain function. It also helps with athletic performance, immune system health, and respiratory health.
Leafy greens such as spinach, kale, arugula, and celery are packed with nitrates, which the body can convert into nitric oxide. In fact, leafy greens contain some of the highest concentrations of nitrates, with arugula, spinach, and lettuce containing about 250 milligrams of nitrates per 3.5 ounces.
When you eat nitrate-rich foods, the nitrates are absorbed into your bloodstream. Then, helpful bacteria in your mouth convert these nitrates into nitrites as you chew. Once in your stomach and bloodstream, these nitrites are then converted into nitric oxide.
To maximize the benefits of leafy greens, it is recommended to consume them raw, as cooking can hinder the production of nitric oxide. There are many delicious ways to incorporate these nutrient-dense greens into your diet, such as salads, smoothies, or pitas.
In addition to their nitrate content, leafy greens also provide other essential nutrients and antioxidants, making them a healthy addition to any meal.

Consume beetroot juice or supplements
Consuming beetroot juice or supplements is a great way to increase nitric oxide levels in the body. Beets are rich in dietary nitrates, which the body can convert to nitric oxide. In one small study, consuming a beetroot juice supplement increased nitric oxide levels by 21% in just 45 minutes. Another study showed that drinking 3.4 ounces (100 ml) of beetroot juice significantly increased nitric oxide levels in both men and women.
Beetroot juice has been linked to a number of health benefits, including improved cognitive function, enhanced athletic performance, and lower blood pressure. This is due to the high nitrate content in beets, which is converted into nitric oxide in the body. The process starts with the absorption of nitrates into the bloodstream, followed by the conversion of nitrates to nitrites by helpful bacteria in the mouth. Once in the stomach and bloodstream, nitrites are then converted into nitric oxide.
To incorporate beetroot juice into your diet, you can try drinking it straight or mixing it with other juices or smoothies. You can also look for beetroot juice blends that combine beetroot with other nitric oxide-boosting ingredients, such as leafy greens or citrus fruits. In addition to fresh beetroot juice, there are also beetroot juice powders and capsules available, which can be a convenient way to boost your nitric oxide levels on the go.
It's important to note that while beetroot juice can effectively increase nitric oxide levels, it should be consumed in moderation as part of a balanced diet. Excessive consumption of beetroot juice may have negative side effects, such as a temporary pink or red discoloration of urine or stool, which is harmless but can be concerning. Additionally, some people may be allergic to beetroot, so it is always recommended to consult with a healthcare professional or a registered dietitian before making any significant changes to your diet.

Snack on antioxidant-rich foods like berries and citrus fruits
Snacking on antioxidant-rich foods is a great way to increase nitric oxide levels in the body. Antioxidants help to prolong the short life of nitric oxide, a gas with a half-life of 1-3 seconds. Found primarily in plant-based foods, antioxidants are molecules that neutralise free radicals, which would otherwise shorten the lifespan of nitric oxide.
Berries are a fantastic source of antioxidants. Tart cherry and blueberries are particularly antioxidant-rich, and snacking on these fruits is a delicious way to increase nitric oxide levels. Strawberries are another great option, and they can easily be added to breakfasts, desserts, or smoothies.
Citrus fruits are also an excellent choice for boosting nitric oxide. Oranges, lemons, and limes are all packed with vitamin C, a powerful antioxidant that helps the body form connective tissues and produces brain chemicals that aid nerve cell communication. In addition to fresh fruit, citrus juice can also be a convenient way to incorporate more citrus into your diet.
Snacking on antioxidant-rich foods like berries and citrus fruits is a tasty and effective way to increase nitric oxide levels in the body. By prolonging the lifespan of nitric oxide, these foods help promote improved blood flow, enhanced exercise performance, and better brain function.

Breath meditation is a simple yet powerful technique that can help reduce stress. It involves focusing your attention on your breath, observing it without judgment, and acknowledging and letting go of any intrusive thoughts. This practice can lead to a sense of relaxation and a more mindful approach to life. It is recommended to start with shorter meditation sessions, gradually increasing the duration over time.
Deep breathing exercises are another effective tool to combat stress. They can be practiced anytime, anywhere, and can be easily incorporated into your daily routine. One such technique is box breathing, which involves sitting or standing with a straight back or lying down with your arms by your sides. Close your eyes if it feels comfortable, and follow these steps:
- Relax your shoulders and release any tension in your jaw.
- Breathe in slowly to a count of four, feeling your belly expand.
- Hold your breath for another count of four.
- Breathe out slowly and steadily through your mouth, counting to four.
- Hold your breath again for a final count of four.
- Repeat this process for as long as you feel necessary.
By including these relaxation techniques in your daily life, you can effectively reduce stress and, in turn, help increase nitric oxide levels in your body.
