These include kidney disease, herpes , and after a person has had a heart attack. A study published in in JAMA found that people taking L-arginine after a heart attack had a higher chance of death, experiencing a repeat heart attack, and being hospitalized than people who did not.

This article does not give a comprehensive list of potential conditions where a person should not take nitric oxide supplements. The supplements may also interfere with medications, such as those for diabetes and high blood pressure.

Anyone thinking about taking nitric oxide supplements should talk to their doctor first to ensure they will not interfere with existing conditions or any other medications they are taking.

Nitric oxide supplements have been available for decades, but as there is little scientific evidence to back up their use for specific health benefits, doctors do not routinely recommend them. Instead, doctors may prefer to recommend lifestyle modifications or medications that scientists have proven to treat medical conditions effectively.

Nitric oxide supplements do not cause many side effects in most people, so some people might choose to try them. However, individuals should make sure that they do not have specific medical conditions that nitric oxide could harm.

A person should always talk to their doctor before taking nitric oxide or any other supplement to make sure they are making a safe, healthful choice.

Pro tip: the less sugar content in your beets supplement, the better. You probably know that citrus fruits — such as oranges, lemons, and grapefruits — are great sources of vitamin C.

Some studies suggest that vitamin C might also increase the amount of nitric oxide synthase, an enzyme essential for NO production.

By boosting NO levels, citrus fruits may also help lower the risk of high blood pressure and heart disease and help optimize brain function. As well as eating citrus fruits whole, or juicing them, try adding the zest to your salad, seafood, or fish dish to boost your intake.

A small study in which eight men drank ml of watermelon juice daily for two weeks showed increased bioavailability of NO. A review suggested increased watermelon intake boosts nitric oxide levels, which may support higher athletic performance and promote healthy blood pressure and blood flow.

Watermelon has also been shown to aid post-workout recovery. The last nitric oxide food on our list is the heart-healthy pomegranate.

The rich red seeds of pomegranates are full of antioxidants that promote the formation of NO and protect it from damage. A test-tube study on pomegranate juice showed that it prevented NO being damaged by oxidative stress. An animal study suggested that pomegranate helps boost the enzyme nitric oxide synthase and blood nitrate levels — both of which are crucial for the formation of nitric oxide.

Other human and animal studies have suggested that the antioxidants in pomegranates can help blood flow more freely, which may help lower the risk of heart conditions. Store-bought juices can be high in sugar and other additives. A smoothie bowl is a great way to start the day or to boost your energy at any time.

These delicious truffles combine a beets powder with collagen, along with dark chocolate or cacao nibs for an extra NO boosting effect.

Scientists agree: Nitric oxide is vital for your long term heart, energy, exercise performance, and brain function. Boost your levels of nitric oxide naturally by increasing your dietary nitrate intake not to be confused with dietary nitrites found in processed meats. Foods high in dietary nitrate include leafy greens, dark chocolate, beets, citrus fruits, watermelon, and pomegranates.

Increasing physical activity through regular exercise may also help to optimize your NO levels. This means the beets you buy today and the beets you buy next week may have a different amount of nutrients and dietary nitrate.

What are Dietary Nitrates? Some studies suggest it can help with age-related brain deterioration. Leafy Greens The best source of dietary nitrate is, without a doubt, organic leafy vegetables.

Out of all vegetables, arugula contains the highest amount of dietary nitrates — mg for g. Toss it into your next salad and pat yourself on the back for treating your body right. Kale — Kale is a rich source of potassium and magnesium. It also contains a significant amount of dietary nitrate to help with nitric oxide production.

Just make sure you lightly steam it to maintain all of its nutrients. It helps your body get rid of sodium, a mineral that can negatively impact healthy blood pressure levels.

Spirulina — In a human research trial, 4. It is also chock-full of vitamins, minerals, and chlorophyll — which help protect cells. Swiss Chard — With bitter leaves and sweet stems, swiss chard has more to offer than just dynamic flavor. It provides the dietary nitrate necessary to maintain a healthy lifestyle.

Try steaming both the leaves and stems before enjoying this power vegetable. Cabbage — Cabbage grows in a variety of colors, all offering the nutrients your body needs to make nitric oxide.

Amino acids Amino acids, such as L-arginine and L-citrulline, are essential in order for your body to be able to produce nitric oxide. L-arginine The amino acid L-arginine, also called arginine, is found in foods such as nuts particularly walnuts and seeds.

Citrus Fruits You probably know that citrus fruits — such as oranges, lemons, and grapefruits — are great sources of vitamin C.

Some research suggests that including arginine from foods like nuts and seeds in your diet can help increase nitric oxide levels in your body. For example, one study in 2, people showed that a higher intake of arginine-rich foods was associated with higher levels of nitric oxide in the blood Another small study found that supplementing with arginine increased levels of nitric oxide after just two weeks Thanks to their arginine content and stellar nutrient profile, regularly eating nuts and seeds has been associated with lower blood pressure, improved cognition and increased endurance 44 , 45 , 46 , Summary Nuts and seeds are high in arginine, an amino acid needed for the production of nitric oxide.

One small study found that citrulline supplements helped stimulate nitric oxide synthesis after just a few hours but noted that it may take longer to see positive effects on health Meanwhile, another study in eight men showed that drinking 10 ounces ml of watermelon juice for two weeks led to significant improvements in nitric oxide bioavailability Recent research suggests that upping your intake of watermelon not only enhances nitric oxide levels but can also improve exercise performance, decrease blood pressure and boost blood flow Summary Watermelon is high in citrulline, which is converted to arginine and then later used in the production of nitric oxide.

Red wine contains many powerful antioxidants and has been tied to a multitude of health benefits Interestingly, some studies have found that drinking red wine could also increase levels of nitric oxide. One test-tube study showed that treating cells with red wine increased levels of nitric oxide synthase, an enzyme involved in the production of nitric oxide Another test-tube study had similar findings, reporting that certain compounds found in red wine enhanced nitric oxide synthase and increased the release of nitric oxide from the cells that line the blood vessels Summary Red wine can increase levels of nitric oxide synthase, which can help enhance nitric oxide levels.

Nitric oxide is a crucial compound involved in many aspects of health, including blood pressure regulation, athletic performance and brain function. Making a few simple swaps in your diet can be an easy and effective way to increase your levels of nitric oxide naturally.

Eating plenty of fruits, vegetables, nuts, seeds and healthy protein foods can optimize nitric oxide levels while also promoting better overall health in the process.

By Gavin Van De Walle, MS, RD. Are Nitrates and Nitrites in Foods Harmful? You can source these fatty acids from walnuts, flaxseeds, chia seeds, hemp seeds, edamame, seaweed, and algae. Antioxidants help prolong the short life of the gas nitric oxide.

The half-life of nitric oxide is between seconds. Foods containing antioxidants neutralize the free radicals that contribute to a shortened nitric oxide lifespan and thus support nitric oxide synthase activity.

Researchers have warned that nitric oxide and its associated benefits could be lost with the increased consumption of processed meats and foods with added nitrate, as opposed to naturally occurring nitrate.

Recent studies show that vitamins in fruits, vegetables, green tea, and black tea block nitrosamine formation. The best foods for ample antioxidant contents include tart cherry, pomegranate juice, blueberries, strawberries, and citrus fruits.

Dump exercises are a powerful way to target your muscles and increase fitness levels. It's a type of advanced stability drill that strengthens muscles, ligaments, and tendons around the knee.

Here's an example of a perfectly executed nitric oxide dump exercise : three sets of 10 reps for a total of around 4 minutes. This quick exercise is meant to be repeated 3 times a day, leading to a total of 15 minutes of exercise time. Nitrite reserved in our skin cells reacts with sunlight to produce what is called dermal nitric oxide.

There are numerous benefits to this phenomenon. Specifically, nitric oxide production on the skin is important for three key reasons: wound healing, dermal immune response, and dermal vasodilation.

Learn more about the endless benefits of getting the right amount of sun to boost nitric oxide levels. Increased stress lowers nitric oxide levels, and lower nitric oxide levels increase stress. It's feedback systems that spiral health out of control.

Symptoms of low nitric oxide include anxiety, depression, and fatigue, which are all made worse by stress. Stressful events can engage the parasympathetic nervous system, which causes the heart to pump and adrenal glands to engage. Try to put plans in place and use tools to prevent stress from reaching this level.

Find more about how the body uses nitric oxide to reduce stress and ways you can manage stress levels for achieving optimal health. It keeps us alive, but mostly we don't think about the way we breathe. But the way we choose to breathe makes a big difference in our quality of life and our health.

One key difference is that breathing through the nose allows nitric oxide production in the nasal cavity. When we breathe through our mouth, there are no nitric oxide production benefits. Nose breathing helps produce nitric oxide that relaxes the muscle around blood vessels and arteries helping the body relax.

SKY meditation is an example of a popular breathing practice that increases nitric oxide and one that drastically:. Most people don't know that the wrong turn in oral health can mean depleted benefits from exercise.

For a long time, researchers didn't understand how post-workout hypotension occurred. After studies were conducted, it was found that anti-bacterial mouthwash is to blame for reduced nitrate levels and thus reduced nitric oxide levels. You don't have to skip the dental floss, and there are natural mouthwashes you can switch to if you're at risk.

Don't waste the cardiovascular benefits of your next workout by using harmful mouthwashes. Fluoride use in municipal drinking water has become the norm.

Toothpaste brands have made it a staple ingredient. The claim is that fluoride is important to prevent cavities. However, you can choose which toothpaste you use and opt for non-fluoridated toothpaste.

Those who drink municipal water are subjected to fluoride, whether they want to ingest it or not. Regardless of your take on fluoride, studies show that fluoride poses a threat to health and suppresses nitric oxide synthesis.

Excessive exposure can deplete nitric oxide production capabilities. Look for toothpaste that avoids fluoride as an ingredient. Natural alternatives to fluoride that protect teeth from cavities include Neem, coconut oil, ozonated olive oil, oregano oil, and myrrh.

Heavy salt use or "salt loading" episodes have been connected to a subsequent decrease in nitric oxide production. Both groups of people who are salt sensitive and who are not salt-sensitive displayed depleted nitric oxide production capabilities after heavy salt usage.

This study tells us that if you want to keep your nitric oxide levels up, avoid salty foods. That means reducing the amount of salt you use or opting for an alternative altogether like miso paste which is soy-based.

Diets rich in saturated fats impact the body's ability to produce nitric oxide. Reduced nitric oxide production means there will be less nitric oxide available to do its job and relax the smooth muscle around arteries. It is suspected that this might be the process by which saturated fats contribute to disturbed endothelial tissue.

The reduction of saturated fats helps avoid this reduction in nitric oxide and will undoubtedly contribute to overall health. It's no surprise that smoking is bad for you, but did you know that smoking drastically reduces your oxid nitric levels.

Smoking impairs endothelial vasodilation and restricts circulation. Exposure to cigarette smoke extract displays irreversible, permanent nitric oxide synthase inhibition in the pulmonary artery endothelial cells.

As a result of this permanent damage, it's suspected that this is the cause of high rate pulmonary and cardiovascular disease in cigarette smokers. If you want to increase your nitric oxide levels, try decreasing your cholesterol. Studies show that high cholesterol levels reduce the bioavailability of nitric oxide, which is part of why this impacts heart health.

Studies show that after treatment of high cholesterol with lipid-lowering drugs, an increase in nitric oxide bioavailability is present. Impaired vasodilation due to high cholesterol can be corrected, and nitric oxide levels could rise once again. When it comes to drinking alcohol, it's not all or nothing.

Small amounts of alcohol have been shown to increase nitric oxide levels. However, high concentrations of alcohol and chronic alcohol usage dramatically reduce endothelial health and nitric oxide bioavailability. Reducing or eliminating alcohol consumption improves nitric oxide levels by allowing nitric oxide synthase to commence.

Unlike smoking, when you reduce your alcohol intake you can repair and boost nitric oxide levels once again.

Learn more about the endless benefits of getting the right amount of sun to boost nitric oxide levels. Increased stress lowers nitric oxide levels, and lower nitric oxide levels increase stress.

It's feedback systems that spiral health out of control. Symptoms of low nitric oxide include anxiety, depression, and fatigue, which are all made worse by stress. Stressful events can engage the parasympathetic nervous system, which causes the heart to pump and adrenal glands to engage.

Reducing or eliminating alcohol consumption improves nitric oxide levels by allowing nitric oxide synthase to commence.

Unlike smoking, when you reduce your alcohol intake you can repair and boost nitric oxide levels once again. Just as a nitric oxide dump workout can boost your nitric oxide production levels, inactivity does just the opposite.

It stagnates nitric oxide production. One study showed that young, healthy individuals who partake in a sedentary lifestyle display endothelial dysfunction and reduced nitric oxide production levels.

Even one walk a day can reverse this. Maintaining high glucose levels ultimately leads to an imbalance of nitric oxide and superoxide , a free radical.

When this imbalance occurs as a result of high sugar intake, endothelial functions become impaired. Kidneys become impacted by too much sugar in this process, and researchers are looking to correct the damage by administering L-arginine and antioxidants.

To reduce blood sugar levels, you can increase water intake, eat more fiber, implement portion control, get adequate sleep, and increase micronutrients. There's no physical test you can take for assessing nitric oxide levels because it's such a short-lived gas.

However, you can infer whether your levels are high or low based on symptoms, your feelings, and your overall lifestyle.

Do you take actions to increase your nitric oxide levels? Are you actively seeking to increase levels by diet and exercise? Wherever you fall on the nitric oxide production spectrum, you can still take charge of your life. Use this list to help you address where you're excelling and where you can improve your nitric oxide game.

The subsequent conversion of nitrites produces nitric oxide, crucial for many physiological functions. Studies have shown that consuming meals rich in nitrates can lower blood pressure, improve blood flow, and prevent blood clots from forming. Nitrate-rich meals can also improve exercise performance by boosting stamina and reducing oxygen needs.

An exceptionally excellent source of nitrates is beets. Studies have shown that consuming beet juice or powder can significantly increase nitric oxide levels and improve exercise performance. Also, leafy greens like spinach and arugula are a great source of nitrates.

According to research, eating leafy greens can lower blood pressure and improve blood flow in people with hypertension. Furthermore, food preparation is crucial in adding nitrate-rich foods to your diet.

While juicing or blending can increase the bioavailability of nitrates, boiling or cooking nitrate-rich foods can decrease their nitrate content. Taking your recommended daily amount of antioxidants is another natural strategy to increase NO levels. Antioxidants are molecules that help stop cellular damage produced by free radicals.

Free radicals can inhibit the generation of nitric oxide and decrease blood flow by harming the lining of blood vessels [ 3 ]. By minimizing free radical damage, antioxidants like vitamin C and polyphenols can help raise nitric oxide levels.

Avoiding meals high in saturated fats, trans fats, and processed sugars is as important as eating foods rich in antioxidants. These meals can potentially worsen free radical damage and reduce nitric oxide synthesis.

Consuming these antioxidant-rich foods moderately and as part of a balanced diet is crucial. However, too much may result in weight gain and other health problems, even though it has many positive health effects.

A healthy lifestyle must include regular exercise, which can also help the body produce more nitric oxide. Exercise raises nitric oxide levels by boosting blood flow, nitric oxide synthase synthesis the enzyme that turns L-arginine into nitric oxide , and inflammation reduction [ 4 ].

Regular exercise can have various health benefits, including reducing your chances of developing diabetes, heart disease, and stroke. Additionally, it can elevate mood, lessen stress, and improve cognitive function.

Aiming for either 75 minutes of high-intensity activity or a minimum of minutes of moderate-intensity exercise per week is recommended. Another all-natural method to raise nitric oxide levels in the body is sun exposure.

Nitric oxide is produced more quickly when skin is exposed to sunshine, which benefits cardiovascular health and general well-being [ 5 ]. When UVB light enters the skin, an internal type of cholesterol is transformed into nitric oxide. Once in circulation, this nitric oxide can assist in controlling blood pressure and enhance cardiovascular health.

The dangers of skin cancer, early aging, and other skin damage are increased by excessive sun exposure. Besides encouraging NO formation, sunlight exposure offers additional health advantages, including elevating mood, improving sleep quality, and boosting vitamin D synthesis.

L-citrulline can help the body produce more L-arginine, which is needed as a precursor to creating nitric oxide. Supplementing these amino acids can help increase levels of nitric oxide naturally. Nitric oxide generation is one of the physiological processes in which L-arginine has a role.

L-arginine supplements can increase nitric oxide production by giving the body the required precursor for nitric oxide production. Studies have demonstrated that L-arginine supplements increase blood flow, lower blood pressure, and improve exercise performance [ 6 ].

Before using L-arginine supplements, you must speak with a healthcare professional. Another amino acid that can help the body produce more nitric oxide is L-citrulline.

The body transforms L-citrulline into L-arginine, which can increase nitric oxide synthesis. L-citrulline supplements have increased cardiovascular health, decreased muscular soreness, and improved exercise performance [ 7 ].

Supplements containing L-citrulline are typically well-accepted and safe, with few documented adverse effects. drugs, such as blood pressure and blood thinners. Heart disease, diabetes, and depression are some disorders that can be worsened by long-term stress.

It may also hinder nitric oxide synthesis, decreasing blood flow and raising blood pressure. Stress management strategies may naturally increase nitric oxide levels and reduce tension [ 8 ].

Including stress-reduction strategies in your daily routine can help you feel less stressed and naturally raise your levels of nitric oxide. Nitric Oxide levels and production can both be significantly impacted by sleep deprivation.

Early morning is usually when nitric oxide levels are highest, and late at night is usually when they are lowest. This indicates that enough sleep is crucial for maximizing nitric oxide generation and preserving cardiovascular health. Lack of sleep lowers nitric oxide synthesis and raises stress levels.

Heart disease, diabetes, and depression are a few of the disorders that can be exacerbated by long-term stress. Getting adequate sleep might naturally raise nitric oxide levels and lower stress.

Nitric oxide is an essential ingredient for maintaining optimal health and wellness. Deficient levels can lead to cardiovascular diseases and other health problems. Fortunately, several natural ways to increase NO levels are available, including regular exercise, adequate sleep, sun exposure, stress management, and dietary modifications.

These natural methods are safe, effective, and easily incorporated into your daily routine. It is important to note that while nitric oxide supplements are available on the market, their safety and efficacy are still being debated, and caution should be exercised when using them.
