Heart Healthy Nutrients Your Heart Desires: Nitric Oxide

Heart Healthy Nutrients Your Heart Desires: Nitric Oxide


It’s more than just Valentine's Day that draws our attention to our hearts. February is Heart Month so I want to give you the nutrition essentials for a healthy heart. Nitric oxide may be the single most important molecule for cardiovascular function. In this post, learn where to get nutrients, which support nitric oxide levels, and how nitric oxide helps your entire cardiovascular and musculoskeletal systems. 

Nitric Oxide & Vasodilators for Optimal Heart Health

Nitric oxide (“N-O” for short”) is a simple molecule with profound effects.  It makes blood vessels dilate and relax. It improves nutrient delivery and use. Beyond that, nitric oxide’s effects on your gut, your brain, and even the mitochondria that power your cells are well researched, but not well known to the public.

Nitric oxide levels go down with age and heart disease, not to mention many other inflammatory chronic conditions.  Since nitric oxide is the hormone for opening up blood vessels and increasing blood flow, it’s no surprise that every heart condition is associated with dysregulated nitric oxide levels.

It is one goal here at Resync to make sure every person knows about the powerful benefits plant-based nitrates can give you. You may have heard of red beet root, but do you know other and even better sources of plant-based nitrates?  

You may have heard about L-arginine, which is another nitric oxide precursor, but it does not appear to be effective for people with heart disease, since it functions on the same pathway that heart disease dysregulates.

Here are also key things to take into consideration when addressing nitric oxide. 

Do you use antibacterial mouthwash regularly? What about antacids like proton pump inhibitors (PPIs)? These two in particular destroy the bacteria you need in order to make the nitric oxide from plant-based nitrates.

With so many causes of low nitric oxide, a lot of research shows that raising nitric oxide levels with plant-based nitrates may potentially help with aspects of heart disease.

Now on the flip side, if you’re young and fit are nitrates going to make a difference? 

Nitric oxide is used in research and by professional athletes to boost long-distance performance (read more on that here), so you’ll have to decide for yourself if you want to rise to your potential, or get left in the dust.

Research on Resync and Heart Health

Earlier in 2020, we partnered with a cardiac rehabilitation clinic in Canada to study the benefits Resync can have on cardiovascular function. I think you’ll want to see these results!

Over the course of 5 weeks (it was cut short due to the pandemic), strain on the heart decreased significantly.

It was the difference between a healthy heart and the start of a heart condition. 

When we separated patients based on average heart health, the results made me say “wow” out loud. The 50% of patients with the most advanced disease improved dramatically!

So what does this mean for you?

This small, open-label study showed that taking 1 to 2 servings of Resync Recovery every day improved heart health in cardiac rehab patients, especially in people with advanced disease. Talk to your cardiologist before making any major changes to your diet, lifestyle, supplements, and medication.

Nitric Oxide, Your Heart, and Your Body

Your veins supply nutrients to the surface of every tissue in your body, so we wanted to help you understand the unique effect nitric oxide can have on the layers of your musculoskeletal system (your bones, muscles, and connective tissues). 


We took a deep dive on the effects of nitric oxide and bone in a recent blog on nitrates and bone health, but here are the takeaways. First, since your blood is made in your bone marrow, and nitric oxide has profound impacts on blood health, nitric oxide can be an essential nutrient for promoting optimal red blood cells. There’s a secondary effect as well, since the structure of the outside of your bones benefits from a healthy blood supply.

Nitric oxide might not be the first thing that comes to mind when you think of the best supplement for bone mineral density or the best supplements for osteoporosis, but decades of science show us when and how to supplement with nitric oxide for better bone health. With or without estrogen therapy, just boosting nitric oxide can strengthen bones in post-menopausal women.

Cartilage & Joints

It’s important to point out that nitric oxide can be made from multiple different enzymes.  Inducible Nitric Oxide Synthase is associated with damage from arthritis, but other nitric oxide metabolites have protective anti-inflammatory potential, according to the research. Early-stage research shows that nitric oxide is essential for the inflammation-resolution process that comes after putting an injured joint in a cast. So far, no studies in humans have been done, so we are not entirely clear on the pro- and anti-inflammatory effects nitric oxide has on cartilage, but it appears that too much and too little is a bad thing


One study suggests that, for tendons, low doses of nitric oxide can enhance collagen synthesis and protein deposition. Outside of this one study, nitric oxide probably helps to make sure these tissues are well-fed, but little research has been done on nitric oxide and tendons or ligaments. 


The effect of nitric oxide on muscle tissues are pretty clear cut - markedly positive across the board.  Nitrates can:

Besides the performance boosting effect of nitrates themselves, the antioxidants in chokeberry and other colorful fruits might also reduce inflammation post-workout.


The under-represented connective tissue that connects all your other tissues is fascia.  Some research shows that nitric oxide is involved in the relaxation and signalling properties of fascia.


Nitric oxide is a regulator of the wound healing process, but like most things, there is a happy medium for optimal function. Other benefits for skin include the ability to mitigate damage from excessive sun exposure, minimize sagging skin caused by excessive oxidative stress, and promoting skin pigmentation in order to avoid further UV damage, according to a number of studies.

What Are The Best Sources of Plant-Based Nitrates? (Not Beets!)

 In food, you can’t count on consistent nitrate levels. But at least you’ll be happy to know that the veggies highest in nitrates are also superfoods in their own right. The very best whole-food plant-based nitrates sources are:

    1. Red Spinach (aka. Amaranth)
    2. Arugula
    3. Spinach (the regular kind)
    4. Bok Choy
    5. Rhubarb
    6. Beet Juice (wildly inconsistent and full of sugar)
    7. Cilantro & Parsley
    8. Red leaf lettuce
    9. Carrots and carrot juice
    10. Basil
    11. Spring Greens
    12. Beet Greens
    13. Collard Greens
    14. Chinese Cabbage
    15. Chard
    16. Cole (aka cabbage and kale)
    17. Beets, yes far from #1

What does Nitric Oxide interact with? What does it synergize with?

Nitric oxide synergizes with other vasodilators since it works outside of the highly regulated arginine pathway. Here’s my short list of the best nutritional vasodilators that open up your blood vessels:

Other Nutrients that may help with nitric oxide absorption and function include:

  • B vitamins (B6, B12, folic acid (B9)) in one study of mice. You must use the active form of vitamin B12, methylcobalamin, since other types of B12 (oxocaobalamin, cobinamide) have negative effects on NO
  • Vitamin C is an Antioxidant involved in recycling spent NO via the cofactor tetrahydrobiopterin
  • Vitamin D has been shown to improve nitric oxide in Black Americans but not Whites, suggesting that it may only be useful for people with low vitamin D (23% of the U.S. is deficient/insufficient)
  • Vitamin E was shown in one trial to increase nitric oxide levels in pregnant women.

The caveat here is that all studies are looking at production of nitric oxide from L-arginine via eNOS, not the Nitrate→ Nitrite → NO pathway. Notably, this study shows that beet juice plus vitamin C may help prevent the production of harmful nitroso compounds, but only in the short term.

What is the Best Dose of Nitrates? Can You Eat Too Many of Them?

As you probably have gathered, there’s a sweet spot for nitrate supplementation: not too much not too little. You see it with bone research, connective tissue research, and when it comes to your heart, excessive nitrate consumption is linked to methemoglobinemia, where your red blood cells aren’t able to hold onto oxygen very effectively.

5–9 mmol nitrate is the most common range of doses for performance enhancing effects, according to one of the foremost nitric oxide researchers. By eating one or two of the ingredients listed above, you can easily get that much in a day.

Is There a Best Time to Consume Plant-Based Nitrates or Take Nitric Oxide Supplement? 

Some research suggests that nitrates should be taken intermittently, since taking it regularly can lead to so-called “nitrate resistance”. Additionally, your natural circadian rhythms affect N-O levels, with naturally lower levels around midday, and higher levels at night. 

When it comes to performance: Research shows that nitrates have their strongest effect when 5 mmol (310 milligrams) is taken per day and when supplementation occured 2–3.5 hours before training or competition. These effects are most pronounced in people with lower baseline cardiovascular fitness.

When it comes to recovery, one study shows that taking nitrates after a workout can have substantial impacts on hypoxic (ie. high elevation and high intensity) exercise.

What is the Best Nitrate Based Supplement?

Since I make sure to bring you quality not seen in any other supplement on the market, I can confidently tell you that Resync Recovery is the highest quality plant-based nitrate supplement on the market. If you don’t believe me, head over to this blog ー where I rank each of the most popular nitrate supplements ー to see why dose, price, standardization, third party certification, and the addition of synergistic bioactive ingredients put Resync Recovery into a class of its own.

If you have never tried Resync products, now is a good time to. You’ll be joining some of the best athletes in the world when you try our blends. But, keep in mind you don't need to be an athlete to treat your heart the right way.

These are world-class supplements not just because of their safety, but because of their effectiveness. Even Pfizer has purchased our Resync Recovery to test the power of it. Resync stands out in the category of beet based products, because it has more to offer than just beets. Treat your heart this month and learn more about it here
