7 Healthy drinks to boost nitric oxide

While our body produces nitric oxide, we can also consume foods and drinks with high levels of this molecule. 

In this article, we’ll explore seven drink sources of nitric oxide that you can enjoy as part of your daily diet. From Pomegranate juice to green tea and red wine, these drinks are delicious and provide several health benefits.

We will also explain how nitric oxide works in our bodies, the benefits of consuming nitric oxide-rich drinks, and the potential risks associated with excessive consumption.

Finally, we’ll provide additional tips and recommendations to help you naturally and safely increase your nitric oxide levels.

How does nitric oxide affect our health?

Nitric oxide (NO) is a gas that our body produces naturally [1]. It is a signaling molecule that helps regulate various physiological processes in our body.

NO plays a crucial role in our cardiovascular health, as it helps dilate blood vessels, improve blood flow, and lower blood pressure.

Various factors, including diet, exercise, and lifestyle, can influence nitric oxide production. For instance, consuming foods and drinks rich in nitric oxide precursors, such as nitrates and nitrites, can help increase nitric oxide levels in our bodies.

Similarly, regular exercise can also stimulate nitric oxide production.

Is nitric oxide good for the body?

The benefits of nitric oxide are vast and extend beyond cardiovascular health. Nitric oxide is involved in various bodily functions, including immunity, muscle growth, athletic performance, brain activity, and sexual health.

However, excessive nitric oxide production can also have harmful effects, such as contributing to oxidative stress and inflammation. Listed below are some advantages of nitric oxide:

Improves blood flow

Nitric oxide’s main job is to relax and enlarge blood arteries, as was already established. The increase in blood flow helps nutrients and oxygen reach muscles, organs, and tissues more efficiently [2].

Reduces blood pressure

Nitric oxide helps lower blood pressure by expanding blood vessels, lowering the risk of hypertension and heart disease. Keeping nitric oxide levels in check can improve cardiovascular health.

Improves athletic performance

Nitric oxide helps muscles receive more blood and oxygen, which improves athletic performance. This improves endurance, lessens tiredness, and speeds up the recovery of the muscles after exercise.

Boosts mental performance

Nitric oxide helps increase blood flow to the brain, which promotes memory and cognitive performance [3]. Additionally, it might lower the risk of neurodegenerative illnesses like Parkinson’s and Alzheimer’s.

Enhances sexual performance

Nitric oxide is essential for the adequate functioning of the vaginal area’s blood vessels, which increases blood flow and enhances male erectile function. It could improve arousal and overall sexual pleasure in women.

Decreases inflammation

Nitric oxide helps reduce inflammation by neutralizing free radicals and controlling the activity of inflammatory cells. This may lessen the chance of developing chronic inflammatory disorders like asthma and arthritis.

Enhances immunity

Nitric oxide has a role in several immune system processes, including controlling immune cell activity and cell-to-cell communication [4]. It helps fight off illnesses by enhancing the immune system.

Improves diabetes health

Nitric oxide has been demonstrated to increase insulin sensitivity, which is advantageous for those who have diabetes. Nitric oxide can aid in better blood sugar regulation by increasing blood flow and glucose absorption in muscle cells.

What drinks are high in nitric oxide?

Now that we have delved into the importance of nitric oxide, let’s explore the top seven healthy drinks that can naturally boost nitric oxide levels.

Incorporating these beverages into your diet can have a positive impact on your cardiovascular health, exercise performance, and overall well-being:

1. Beetroot juice

Beetroot juice is one of the most potent sources of nitric oxide precursors, such as nitrates and nitrites [5].

Our bodies convert these compounds into NO, which improves blood flow and reduces blood pressure. Drinking beet juice has also enhanced athletic performance and reduced fatigue.

Beetroot juice is exceptionally rich in nitrates, which are compounds naturally found in beets. When you consume beetroot juice, these nitrates are converted into nitric oxide within the body.

Research suggests that regular consumption of beetroot juice may lead to a significant reduction in blood pressure.

The nitric oxide generated from beetroot juice helps regulate blood pressure levels, making it a potential aid for those with hypertension.

2. Pomegranate juice 

Pomegranate juice contains plant-based compounds called polyphenols, which have antioxidant and anti-inflammatory properties [6].

These compounds can improve heart health by increasing blood flow, reducing inflammation, and lowering blood pressure.

Pomegranate juice contains compounds that stimulate the endothelium (the inner lining of blood vessels) to produce nitric oxide. This process contributes to vasodilation, promoting better blood flow.

Enjoy a refreshing and tasty drink with pomegranate juice packed with antioxidants and a great source of nitric oxide. This unique beverage is simple to add to your daily routine and has several health advantages.

3. Cocoa

Cocoa is a rich source of flavonoids, particularly flavanols like epicatechin [7]. Flavonoids are powerful antioxidants that have been linked to various health benefits, including improved nitric oxide production.

The flavanols in cocoa and dark chocolate have been shown to promote vasodilation, which relaxes blood vessels and supports nitric oxide production. This enhanced blood flow can contribute to cardiovascular health.

Regular consumption of dark chocolate or cocoa has been associated with a reduced risk of heart disease.

The vasodilatory effects of nitric oxide contribute to better circulation and overall cardiovascular well-being.

4. Green tea

Did you know that green tea contains antioxidants and other beneficial compounds that can enhance brain function, increase metabolism, and lower the likelihood of chronic diseases?

It also contains a small amount of nitric oxide precursors, which can help improve blood flow and lower blood pressure.

Numerous bioactive substances, such as the antioxidant catechins, are present in green tea. Epigallocatechin gallate (EGCG), the most prevalent and effective catechin in green tea, is one of these catechins.

Nitric oxide synthase (NOS), the enzyme that generates nitric oxide in the body, has been observed to have increased activity in response to EGCG [8].

5. Watermelon juice

A refreshing drink for hot summer days, watermelon juice is another excellent source of nitric oxide precursors, particularly the amino acid L-citrulline.

This compound is converted into nitric oxide in our body, which helps improve blood flow and reduce muscle soreness. 

Drinking watermelon juice can also help improve cardiovascular health and reduce the risk of chronic diseases.

L-citrulline, an amino acid essential for nitric oxide synthesis, is abundant in watermelon. After ingestion, L-citrulline is changed by the body into L-arginine, another amino acid.

Then, the enzyme that generates nitric oxide, nitric oxide synthase (NOS), uses L-arginine as a substrate.

6. Citrus juice

Citrus fruits and their juices are renowned for their refreshing taste and vibrant colors, but they also offer a host of health benefits, including their potential to boost nitric oxide production [9]. 

Vitamin C has been shown to enhance nitric oxide production and promote its bioavailability. It helps maintain nitric oxide’s effectiveness in relaxing blood vessels and improving circulation.

Moreover, the improved nitric oxide levels associated with citrus fruit consumption can contribute to better cardiovascular health. Vasodilation helps reduce blood pressure and enhance overall circulation.

7. Red wine 

Red wine is rich in polyphenols, notably a compound called resveratrol [10]. This compound has been shown to have numerous health benefits, including improving cardiovascular health, reducing inflammation, and protecting against oxidative stress.

Red wine also contains nitric oxide precursors, which can help improve blood flow.

Incorporating these seven drink sources of nitric oxide into your daily diet can help improve your cardiovascular health, boost athletic performance, and reduce the risk of chronic diseases. 

However, it’s essential to remember that moderation is vital, and excessive consumption of these drinks can adversely affect your health.
