What does nitric oxide do for the body?

So what does nitric oxide do? Nitric oxide is a molecule produced in the body that contributes to a process called vasodilation. Nitric oxide vasodilation is what helps blood vessels relax, which allows for increased blood flow and circulation throughout the body. Having higher levels of nitric oxide is ideal for overall health.

Top 6 nitric oxide health benefits for everyone

So we’ve answered the question of “What does nitric oxide do for the body?” But you might still be wanting some specific examples of nitric oxide benefits. This section will cover some of the top nitric oxide health benefits you should know about.

1. Improves heart health

One of the biggest benefits of nitric oxide regards heart health. Nitric oxide is important for the body’s circulation, as well as helping blood vessels to relax. Having a good level of nitric oxide contributes to a healthy cardiovascular system, lowering blood pressure and reducing the risk of cardiovascular disease.

2. Reduces inflammation

Nitric oxide also greatly influences inflammation. It’s able to act as an anti-inflammatory under normal conditions, but can also help produce inflammation when it’s truly needed. Maintaining a good level of nitric oxide helps to reduce the inflammation that negatively affects the body.

3. Improves oxygenation

Another big benefit of nitric oxide is its ability to help improve oxygenation. Nasal nitric oxide is generated in the sinuses, which enters your body when you breathe in and travels to the lungs and heart. This helps to improve the blood flow needed to carry oxygen throughout your body.

4. Increases physical endurance

Nitric oxide is also great for athletes and those with an active lifestyle. It increases blood flow to the muscles, allowing for increased energy and endurance during physical activity. This also helps decrease muscle soreness and improve recovery time afterwards.

5. Reduces erectile dysfunction

Those struggling with erectile dysfunction can also benefit from increased levels of nitric oxide. Since nitric oxide improves blood flow, it is viewed as a natural way of combating this issue. Many even take supplements in order to help.

6. Helps manage type 2 diabetes

Nitric oxide can also combat type 2 diabetes. Since type 2 diabetes impairs nitric oxide production, it is believed that increasing nitric oxide levels helps prevent and manage it. Studies have shown that having more nitric oxide increases insulin sensitivity and improves blood sugar control.

10 best ways to increase nitric oxide

Those wondering how to increase nitric oxide will be pleased to know it can be done in many different ways. These are some of the best ways to increase the body’s nitric oxide levels.

1. Practice nasal breathing

Since nitric oxide helps move oxygen throughout the body, it makes sense that practicing nose breathing for nitric oxide would be helpful. Nasal nitric oxide is generated in your nose and sinuses, and then travels to your lungs and throughout your body as you inhale. By using nasal breathing exercises, you can increase the amount of nitric oxide entering your body and flowing to your lungs and heart.

2. Eat vegetables high in nitrates

Several vegetables contain nitrates, which are converted into nitric oxide when consumed. By digesting more nitrates, you can easily create more nitric oxide in your body and experience more of its health benefits. Some vegetables you can eat include spinach, celery, arugula, lettuce, and beetroot.

3. Consume more antioxidants

Since nitric oxide is an unstable molecule, it tends to break down easily. Antioxidants can actually help stabilize these molecules and reduce the rate of breakdown. Try eating plant-based foods that contain vitamin C, vitamin E, polyphenols, and glutathione to support the nitric oxide in your body.

4. Take nitric oxide supplements

If you’re someone who prefers taking daily vitamins and supplements, there are options that can help increase nitric oxide. While there aren’t any supplements that are specifically for nitric oxide, there are several options containing ingredients that will help boost the amount of nitric oxide in your body. The two most common ingredients are L-arginine and L-citrulline.

5. Use less mouthwash and fluoride

Fluoride – typically found in water or toothpaste – and mouthwash have the ability to reduce and/or suppress nitric oxide. Overuse of one or both can impact your body’s ability to produce nitric oxide. Limiting your use of both is a great way to protect your body’s nitric oxide production capabilities.

6. Exercise

Exercise is a natural way of helping your body produce nitric oxide. This is because exercise improves endothelial function, which is what helps create nitric oxide in the first place. Combining aerobic and anaerobic exercises you enjoy for at least 30 minutes, 3 times a week, is all you need in order to see results.

7. Get more natural sunlight

You have a chemical called nitrite in your skin cells, which produces dermal nitric oxide. Sun exposure helps your skin turn nitrite into nitric oxide, allowing it to help heal wounds, build dermal immunity, and improve your skin’s blood flow. Making a commitment to spend more time in the sun is a sure way to help increase your dermal nitric oxide.

8. Reduce your stress

Stress is part of life, but high stress levels actually decrease your nitric oxide. Low nitric oxide levels can also cause you to feel more stressed. Making attempts to eliminate stress where you can will help keep your nitric oxide levels adequate and help you feel more relaxed throughout the day.

9. Stick to a healthy diet

While some foods help increase nitric oxide, other foods and beverages can actually decrease it. Too much salt, saturated fat, cholesterol, sugar, and alcohol can all negatively affect your body’s ability to produce nitric oxide. Making an effort to choose healthier food and drinks will help maintain your nitric oxide production.

10. Quit smoking

Smoking or prolonged exposure to cigarette smoke can cause irreversible damage to your pulmonary and cardiovascular systems, leading to a higher risk of disease in these systems. It can also greatly reduce your nitric oxide levels as a result. Making an effort to quit smoking, or avoiding being around cigarette smoke, can make a big difference in your nitric oxide levels and your overall health.

Top 5 breathing exercises to increase nitric oxide

Nitric oxide breathing exercises are some of the best ways to increase the amount of nitric oxide in your body. But it’s important to figure out which ones will work best for you. Here are some of the top breathing exercises to increase nitric oxide.

1. Buteyko breathing

The Buteyko Method is a breathwork technique created by Dr. Konstantin Buteyko in the 1950s. First introduced in Russia, it gained popularity in Australia and the UK in the early 1990s. Many use Buteyko breathing for nitric oxide to improve their breathing and cognitive functioning.


  1. Sit up in a chair, keeping your spine straight.
  2. Relax your respiration muscles as best as you can.
  3. Take a few minutes to breathe as you normally would.
  4. When you feel ready, take your last exhale and hold your breath.
  5. Use your thumb and index finger to plug your nose.
  6. The next step depends on whether you’re new to Buteyko or more experienced.

    a. If you’re a beginner, opt for the Control Pause. Hold your breath until you feel the urge to breathe, then let go and inhale through your nose.

    b. If you’re comfortable, you can try the Maximum Pause. Hold your breath for as long as possible (aiming for double the length of the Control Pause). Once you feel uncomfortable, let go and inhale through your nose.
