Best Nitric Oxide Foods for Better Blood Flow & Sexual Health

When it comes to men’s health, nitric oxide (NO) doesn’t get nearly enough credit. This tiny molecule keeps blood flowing, fuels your workouts, and powers your performance—inside and outside the gym. The best nitric oxide foods help your body make more of it naturally, giving you better energy and endurance where it counts.

On an episode of the Women Want Strong Men podcast, nitric oxide expert Dr. Nathan Bryan explained how certain habits can block NO production, no matter how healthy your diet is. Save the episode below for more insights on what to avoid and how to optimize your levels.

Today, we’ll break down how nitric oxide works, what helps your body make more of it, and the foods that support stronger blood flow and better performance. Let’s dive in. 

Why Nitric Oxide Drops With Age (& What To Do About It)

Nitric oxide levels naturally decline as we get older, especially after age 40. This isn’t just a symptom of aging—it’s a byproduct of stress, poor sleep, inactivity, and oxidative damage in your cells. When nitric oxide production slows, it affects everything from heart health to sexual function.

However, diet and daily habits can help you restore balance. Exercise, deep sleep, and eating nitrate-rich foods can all support your body’s nitric oxide pathways. A few consistent lifestyle shifts (like walking outside daily and cutting back on alcohol) can go a long way in helping your blood vessels stay flexible and strong.

Best Nitric Oxide Foods for Blood Flow and Sexual Health

The right foods can help your body produce more nitric oxide naturally to improve circulation, stamina, and overall performance. Here are the best nitric oxide foods to include in your routine, each supporting your blood flow in a unique way:

  1. Nitrate-Rich Vegetables
  2. Polyphenol- and Antioxidant-Rich Foods
  3. Foods with Citrulline and Arginine
  4. Fermented and Gut-Friendly Foods

Nitrate-Rich Vegetables

Beets, arugula, spinach, and celery are the gold standard of nitrate-rich foods. Your body converts these nitrates into nitric oxide, especially when your oral bacteria are healthy. 

Dr. Bryan emphasizes chewing thoroughly and avoiding antiseptic mouthwash, which can kill the bacteria that help with this conversion. These vegetables boost blood flow while supporting brain and heart function.

Polyphenol- and Antioxidant-Rich Foods

Foods high in polyphenols—like pomegranates, blueberries, dark chocolate (70%+), green tea, and citrus fruits—protect nitric oxide from breaking down too quickly. They reduce oxidative stress in blood vessels, allowing nitric oxide to circulate longer. 

Think of these foods as bodyguards for your NO production. They keep your arteries flexible and your energy levels steady.

Foods with Citrulline and Arginine

Watermelon, salmon, chickpeas, nuts, and seeds provide the amino acids citrulline and arginine, both key building blocks for nitric oxide synthesis. While many supplements overpromise, these foods give your body a steady, natural supply. 

It’s also worth noting that true deficiencies in these amino acids are rare. More often, low nitric oxide comes from poor conversion at the enzyme level, so optimizing your vascular health is key. Combined with regular exercise, these foods can help you maintain strong circulation.

Fermented and Gut-Friendly Foods

Your gut and oral microbiomes play major roles in nitric oxide production. Foods like kefir, yogurt, kimchi, sauerkraut, and fiber-rich vegetables promote a healthy bacterial balance, helping your body efficiently convert nitrates into nitric oxide. Pairing these with nitrate-rich vegetables creates a powerful one-two punch for your vascular health.

Which Habits Are Bad for Nitric Oxide?

Even the best nitric oxide foods won’t help if you’re unknowingly sabotaging your production. Here are some everyday habits that can blunt your nitric oxide response without you realizing it.

  • Antiseptic mouthwash: Kills oral bacteria needed to convert nitrates to nitric oxide. Swap for gentle rinses or tongue scraping.
  • Fluoride-heavy toothpaste or unfiltered water: Can disrupt your oral microbiome. Use filtered water and fluoride-free options if you can.
  • PPIs (acid blockers): Impair gastric nitric oxide pathways. Consider discussing alternatives with your healthcare provider if you use PPIs long-term.
  • Ultra-processed foods and alcohol: Damage blood vessels and slow nitric oxide generation. Stick with whole foods and moderate drinking.

Small tweaks can make a big difference in your nitric oxide levels and overall energy.

How to Eat for Nitric Oxide: Timing, Chewing & Simple Routines

The way you eat affects how much nitric oxide your body can make. Chewing thoroughly, breathing through your nose, and avoiding mouthwash right before or after meals help preserve the bacteria needed for nitrate conversion.

Try eating nitrate-rich foods in the morning when nitric oxide levels are lowest, and aim for at least one serving of leafy greens or beets daily. Pairing polyphenol-rich foods (like pomegranate or green tea) with nitrate vegetables amplifies the effect. Hydration also matters—proper mineral balance keeps your blood vessels responsive.

Daily Habits That Supercharge Nitric Oxide

You can amplify your results by stacking nitric oxide-friendly habits with your diet. Here are a few examples to consider adding to your routine. 

  • Morning sunlight and light movement: Increases circulation and nitric oxide release.
  • Resistance and cardio training: Both boost nitric oxide synthase activity.
  • Red light or sauna sessions: Stimulate nitric oxide release and improve vascular tone.
  • Sleep and stress management: Keep blood vessel function and nitric oxide levels stable.

When you combine these with the best nitric oxide foods, your body runs smoother, your workouts feel stronger, and your performance (both physical and sexual) improves.

Do Nitric Oxide Supplements Work?

They can, if you choose the right ones. Not all nitric oxide supplements are created equal, and many on the market don’t actually increase NO levels in the body. That’s why we’re big advocates of Dr. Bryan’s nitric oxide supplements, which are backed by clinical research.

His NO Beetz and Nitric Oxide Releasing Lozenges are formulated to restore nitric oxide directly, not just provide precursors like beetroot or arginine. They work instantly to open blood vessels, improve oxygen delivery, and enhance both performance. Many of our patients notice better energy, stamina, and recovery within days.

Keep in mind: many NO supplements rely on your oral microbiome to convert ingredients into nitric oxide, so poor oral health habits can limit their effectiveness. Dr. Bryan’s formulas are different because they provide nitric oxide directly, bypassing the need for that conversion step. 

We still encourage supporting your oral microbiome with healthy habits, but even if that’s a work in progress, these supplements can still deliver results. In our clinics, we often use nitric oxide supplements as part of a full optimization plan combining high-quality nutrition, hormone balance, and vascular support. 

Why Nitric Oxide Foods Can Improve ED

Erectile dysfunction is often a result of poor blood flow, and thus a sign of low nitric oxide. Medications like sildenafil and tadalafil rely on nitric oxide to relax blood vessels, so if your body isn’t making enough, those drugs can underperform. 

Eating nitrate-rich foods and restoring nitric oxide pathways can help these medications work better. That’s why addressing nitric oxide isn’t just about diet, but about your overall vascular and hormonal health.

Sample One-Day Nitric Oxide Meal Plan

  • Breakfast: Spinach and arugula omelet with citrus on the side; green tea.
  • Lunch: Beet and walnut salad with a kefir-based dressing; handful of blueberries.
  • Midday Snack: Watermelon and dark chocolate (70%+).
  • Dinner: Grilled salmon with roasted celery and garlic; sauerkraut on the side.

Simple, whole-food meals like these keep nitric oxide production steady throughout the day.

Nitric Oxide Benefits for Men: Boost Energy, Circulation, & Sexual Health

Feeling a little off lately? Maybe your energy levels feel lower than usual, your workouts aren’t hitting the same, or your performance in the bedroom is less than ideal. If any of that resonates, low nitric oxide levels might be the culprit. Many men aren’t aware of powerful nitric oxide benefits like improved circulation, stamina, heart health, and even sexual performance. 

Nitric oxide (NO) plays a huge part in our overall well-being. In fact, it’s so crucial that three scientists won a Nobel Prize back in 1998 for discovering its powerful effects on the body. Let’s break down what it is, why men need it, and how you can boost your levels for better health.

What Is Nitric Oxide (NO)?

Nitric oxide (NO) is a molecule made up of one nitrogen and one oxygen atom, and it’s produced naturally in the body—mostly in the lining of your blood vessels, known as the endothelium. It helps your blood vessels relax and expand, which means more oxygen and nutrients can reach your muscles and brain. 

Good blood flow is essential for everything from brain function and heart health to muscle recovery and sexual function. Without enough nitric oxide, things start to slow down, and your body can’t perform at its best.

What are the Nitric Oxide Benefits for Men?

Most men don’t think twice about circulation until there’s a problem. But the truth is, nitric oxide is quietly working behind the scenes to support nearly every major system in your body. 

From helping your heart pump efficiently to helping you maintain strong erections, nitric oxide is a foundational part of men’s health. When your levels drop, the ripple effect can be felt everywhere—your energy, stamina, and sexual performance all take a big hit.

Nitric Oxide and Circulation

Your body relies on healthy circulation to deliver oxygen and nutrients to every organ, muscle, and tissue. Nitric oxide helps keep that system running smoothly by improving blood flow, reducing plaque buildup, and lowering your risk of clotting. That’s why it’s often called a “miracle molecule” in cardiovascular health.

Nitric Oxide and Chronic Disease

The decline of nitric oxide production is one of the earliest markers of cardiovascular disease—and it starts earlier than most people realize. By your thirties, NO levels begin to drop by about 20% every decade. By age 65, most men have lost up to 85% of their nitric oxide production. Low nitric oxide levels are also linked to:

  • High blood pressure
  • Type 2 diabetes
  • Poor circulation
  • Low energy
  • Erectile dysfunction

Factors like smoking, poor diet, lack of exercise, oxidative stress, and even overuse of certain medications (like antacids or NSAIDs) can make things worse.

Nitric Oxide and Erectile Dysfunction

In many cases, erectile dysfunction comes down to one thing: poor blood flow. And nitric oxide is what allows that blood to get where it needs to go. Here’s how it works:

  • Nitric oxide activates an enzyme called guanylyl cyclase.
  • This increases levels of cGMP, which causes arteries in the penis to widen.
  • Blood flows into the spongy tissue known as the corpus cavernosum, creating an erection.

ED medications like prevent cGMP from breaking down, helping you maintain that blood flow. But here’s the kicker: if you’re not producing enough nitric oxide to begin with, these medications might not be as effective. If that’s the case, boosting your NO levels can make a big difference in both natural and medicated sexual performance.

What are the Signs of Low Nitric Oxide?

You don’t need a lab test to suspect your nitric oxide levels are low because your body will give you clues. While the symptoms can be subtle at first, they often become more noticeable over time. 

If you’ve been dealing with unexplained fatigue, cold extremities, or poor performance, it’s worth digging deeper. Identifying these signs early could help you take action before bigger health issues set in. Some common signs of low nitric oxide levels include:

  • Chronic fatigue or low energy
  • Cold hands and feet
  • Slower workout recovery
  • Brain fog
  • Difficulty getting or maintaining erections
  • High blood pressure

How to Naturally Boost Nitric Oxide

If your nitric oxide levels are trending low, the good news is there’s a lot you can do about it. Lifestyle changes and smart habits can naturally support your body’s ability to produce more NO. These strategies not only help restore energy and blood flow but also improve your overall cardiovascular health and long-term vitality.

Here are the best ways to naturally boost nitric oxide: 

  1. Regular Exercise
  2. Skip Antiseptic Mouthwash
  3. Check Your Medications
  4. Eat Nitrate-Rich Veggies
  5. Quit Smoking
  6. Optimize Your Sleep
Lifestyle Changes to Boost Nitric Oxide | Victory Men's Health

Regular Exercise

Exercise is one of the most effective ways to unlock nitric oxide benefits by increasing your body’s natural production of it. The more you move, the more your body produces NO—and the more NO you produce, the better your endurance becomes. Aim for at least:

  • 150 minutes of moderate activity per week (like brisk walking)
  • OR 75 minutes of vigorous activity (running, swimming, biking)

Skip Antiseptic Mouthwash

Your mouth plays a surprisingly big role in nitric oxide production. Certain oral bacteria convert nutrients from your food into usable NO, but many common products like mouthwash and fluoride toothpaste can kill those helpful bacteria. 

Cutting back or switching to a more natural oral care routine (like alcohol-free mouthwash or oil pulling) may help support this part of the nitric oxide process.

Check Your Medications

Over-the-counter meds like ibuprofen, aspirin, statins, and daily antacids may seem harmless, but they can interfere with how your body produces nitric oxide. If you’re taking these regularly, especially long term, it’s worth having a conversation with your provider. There may be better alternatives that don’t block one of your body’s most important molecules.

Eat Nitrate-Rich Veggies

Your diet has a direct impact on your nitric oxide levels (and your erections), especially when it comes to vegetables. Leafy greens and root vegetables are packed with natural nitrates that your body can turn into nitric oxide. The key is consistency and variety. Try to get a few servings daily, and whenever possible, eat them raw or lightly cooked to preserve their nutrient content. 

Here are some nitric oxide allies to incorporate into your diet: 

  • Spinach
  • Arugula
  • Kale
  • Beets
  • Radishes
  • Cabbage

Quit Smoking

If you needed one more reason to quit, here it is: smoking is a nitric oxide killer. It damages the endothelium (where NO is made), constricts blood vessels, and drastically reduces circulation. 

Quitting smoking is one of the fastest ways to experience nitric oxide benefits by improving its availability and supporting better heart health, lung function, and performance.

Optimize Your Sleep

Poor sleep actively reduces nitric oxide production by impairing endothelial function. Your endothelium is the thin lining of your blood vessels responsible for releasing nitric oxide, and when sleep is cut short or disrupted, that system can’t function properly. Over time, this can lead to higher blood pressure, poor circulation, and decreased vascular flexibility.

To support your nitric oxide levels, aim for 7–9 hours of quality sleep per night, maintain a consistent bedtime, and avoid screens or heavy meals close to lights out. Better sleep means better recovery, better blood flow, and a stronger foundation for your overall health.

Should You Take Nitric Oxide Supplements?

Before deciding whether to start taking nitric oxide supplements, speak with your healthcare provider to make sure it’s the right choice. They can help you not only make the decision, but make sure you choose a high-quality supplement. 

There are plenty of NO supplements on the market promising increased blood flow, better workouts, and improved performance. The only problem? Many are built around L-Arginine or L-Citrulline alone, which—despite the hype—won’t do much without other co-factors present. 

In fact, research from the American Heart Association shows that long-term L-Arginine supplementation doesn’t significantly boost NO levels or improve blood vessel function. Other products toss in beet root extract or kale powder, but those ingredients alone don’t guarantee a therapeutic dose of nitrates. You want a product that’s:

  • Clinically tested in human trials
  • Proven to restore nitric oxide production
  • Backed by real results, not just marketing

When working with patients who want to boost their NO levels, we recommend N1O1 lozenges developed by Dr. Nathan Bryan, the world’s leading expert on nitric oxide production. They’re scientifically formulated to rapidly deliver nitric oxide and bypass the common pathways that become less effective as we age. 

It’s one of the few products on the market that actually lives up to the promise of real nitric oxide benefits.

Nitric Oxide Questions Our Patients Ask

Does Nitric Oxide Help With ED?

In some cases, yes! Nitric oxide is crucial in getting and maintaining erections by relaxing blood vessels and improving blood flow to the penis. For many men, increasing NO levels can significantly improve erectile function. 

However, if ED is caused by low testosterone, nerve damage, or psychological factors like anxiety or stress, nitric oxide alone may not be enough. In those cases, a more comprehensive approach may be needed. Your provider may recommend combining an NO supplement with hormone therapy or other ED treatments. 

Is Nitric Oxide Safe to Take Every Day?

If you’re using a high-quality, clinically tested supplement and following the right dosage, daily use is generally safe for most people. But not all products are created equal, so it’s important to consult with your provider—especially if you’re taking other medications or have health concerns.

Can I Combine Nitric Oxide with ED Medications?

In many cases, yes, and the combination can actually improve your results. Nitric oxide boosts blood flow, while ED medications help that effect last longer by preventing cGMP breakdown. Just make sure you’re working with a reputable provider who can guide you on safe, effective use and monitor any changes. 

What Foods Boost Nitric Oxide Naturally?

Leafy greens, beets, radishes, and cabbage are all rich in natural nitrates that your body can convert into nitric oxide. Try to eat them fresh and regularly, as cooking or processing can reduce nitrate content. A varied, veggie-forward diet is great for anyone looking to maximize nitric oxide benefits. 

Does Nitric Oxide Boost Testosterone?

While nitric oxide doesn’t directly increase testosterone, it plays a supportive role in overall men’s health. Better blood flow means improved performance, more effective workouts, and even better nutrient delivery—all of which can positively influence your hormone balance and energy levels.

Nitric Oxide for Men’s Health: Insights from Dr. Nathan Bryan & Amy Stuttle

When it comes to performance, vitality, and longevity, few things are more important than nitric oxide for men’s health. This small but mighty molecule impacts nearly every system in your body—from your cardiovascular health and energy levels to your focus, recovery, and sexual function.

On an episode of the Women Want Strong Men Podcast, Victory Men’s Health CEO Amy Stuttle sat down with nitric oxide expert Dr. Nathan Bryan to unpack what nitric oxide really does, why your levels decline as you age, and how to naturally restore balance for better health, energy, and performance. Save the full episode below, and let’s dive in.

What is Nitric Oxide?

Nitric oxide (NO) is a gas naturally produced by the lining of your blood vessels. Think of it like a signal your body uses to help blood flow efficiently throughout your system. Dr. Bryan explains it like this:

“Nitric oxide acts like a hormone—it tells your blood vessels to relax and open up so more oxygen and nutrients can reach your muscles, brain, and organs.”

That means better blood flow, sharper focus, and more energy. Nitric oxide also helps your immune system fight off viruses and bacteria, supports healthy brain communication, and plays a key role in sexual function by improving circulation where it matters most.

The problem? As you age (or if you live with certain lifestyle habits) your body’s ability to produce nitric oxide declines. That can set off a chain reaction affecting everything from your endurance to your heart health.

What Causes Low Nitric Oxide Levels?

You might be doing everything “right” on paper—exercising, eating well, managing stress—but still struggle with fatigue, poor circulation, or low libido. Often, the missing piece is low nitric oxide. This isn’t something your doctor usually checks for, yet it’s one of the earliest signs that your blood vessels aren’t functioning as they should.

Certain habits, medications, and even seemingly harmless routines can interfere with nitric oxide production. According to Dr. Bryan, these are the top causes of low nitric oxide levels:

  1. Endothelial Dysfunction
  2. Poor Nutrition
  3. Mouthwash and Toothpaste Use
  4. Antacid or PPI Use

Endothelial Dysfunction

The endothelium—the thin layer of cells that lines your blood vessels—is responsible for making nitric oxide. When it becomes damaged or inflamed (often from poor diet, lack of exercise, or chronic illness), nitric oxide production plummets. This dysfunction is directly linked to heart disease, diabetes, and kidney problems.

Poor Nutrition

Your body needs the right building blocks to create nitric oxide, and those building blocks come from nitrate-rich vegetables. Without enough greens and beets in your diet, production slows down.

Mouthwash and Toothpaste Use

Believe it or not, many antiseptic mouthwashes destroy the beneficial bacteria in your mouth that help convert nitrates into nitric oxide. Dr. Bryan recommends using a fluoride-free, non-antibacterial toothpaste and avoiding harsh mouthwashes whenever possible.

Antacid or PPI Use

Proton pump inhibitors (PPIs) are common heartburn medications that can completely block nitric oxide production by reducing stomach acid. Without stomach acid, your body can’t convert nitrates into nitric oxide.

How to Naturally Boost Nitric Oxide

Now, for the good news: your body can bounce back. Even if nitric oxide production has dipped with age or lifestyle, there are proven ways to restore it naturally. Supporting nitric oxide doesn’t mean just taking a single supplement and calling it a day—it’s about helping your body work the way it was designed to.

Here’s how to naturally boost nitric oxide levels:

  1. Eat More Nitrate-Rich Foods
  2. Get Moving
  3. Protect Your Oral Microbiome
  4. Maintain a Healthy Lifestyle

Eat More Nitrate-Rich Foods

Leafy greens like spinach, kale, arugula, and beets are your best friends here. Try buying from local farmers’ markets where produce tends to have higher nutrient and nitrate content.

Get Moving

Exercise is one of the most effective ways to increase nitric oxide production naturally. Regular physical activity helps your blood vessels stay flexible and responsive.

Protect Your Oral Microbiome

Skip the fluoride and antiseptic rinses. Instead, use gentle, fluoride-free toothpaste and let your body’s natural oral bacteria help maintain nitric oxide balance.

Maintain a Healthy Lifestyle

Sleep, hydration, and stress management all play a role in maintaining nitric oxide levels. If you’re chronically stressed or sleep-deprived, your nitric oxide levels will likely suffer too.

Why Nitric Oxide for Men’s Health Matters

For men, nitric oxide plays a role in how you feel every day. When your nitric oxide levels are optimized, you think clearer, move easier, recover faster, and perform better in every sense of the word. It’s the foundation for feeling strong, confident, and capable—no matter your age.

Here’s how nitric oxide supports men’s health across the board:

  • Heart health – Better blood flow means lower cardiovascular risk.
  • Sexual function – Stronger erections and improved performance.
  • Workout recovery – Faster oxygen delivery to muscles.
  • Energy and focus – Enhanced oxygenation to the brain.

Nitric Oxide Supplements: What to Know

While there are countless nitric oxide supplements online, not all are effective or even scientifically backed. Dr. Bryan has patented several nitric oxide products supported by research, including lozenges and formulas used in clinical trials. We often recommend daily nitric oxide support as part of a larger plan to improve circulation, cardiovascular health, and overall energy.

“When you restore nitric oxide production, you’re improving blood flow everywhere—from your heart and brain to your muscles and sexual organs,” says Dr. Bryan.

If you’re considering nitric oxide supplements, it’s best to talk with a men’s health provider who understands how they fit into your broader health goals.
