Nitric Oxide (NO) is one of the more important substances in the body, as it can significantly improve cardiovascular health by widening the blood vessels. NO levels are ordinarily boosted through regular exercise, although researchers are continually uncovering foods and supplements, such as HeartGreens, that can also do the job. Although most supplements focus on amino acids like l-arginine as a way to raise NO levels, others are gradually looking at the potential for making products entirely out of nitrate-rich foods (like arugula or beets) to achieve the same effect.
Below we take an in-depth look into HeartGreens, to see whether this superfood supplement has the ingredients necessary to improve cardiovascular health, and protect against heart disease.

What You Need To Know About HeartGreens
HeartGreens is a superfood supplement that aims to protect customers’ heart and cardiovascular health. It works by providing consumers with a source of leafy, nitrate-rich greens, which supposedly raises the levels of Nitric Oxide (NO) in the body. Raised NO levels have the effect of widening the body’s blood vessels, which increases the rate of oxygenation in the bloodstream and reduces the risk of heart disease. Readers should note however that the benefits of supplementing nitrate-rich ingredients are likely only experienced by those who are already NO-deficient, or who are at an elevated risk of heart disease.
This product is produced and sold by HumanN, an American supplement manufacturer co-founded and led by a group of scientific researchers. Perhaps the most interesting of these is Dr Nathan Bryan, a well-known researcher of Nitric Oxide. Dr Bryan has researched and written dozens of papers, articles, studies, and books on Nitric Oxide which makes him appear to be something of an expert on the subject. Readers should note however that he authored or led many of the studies which he now uses as evidence that his products and ingredients work; a serious conflict-of-interest violation.
What Are The Side Effects Of HeartGreens?
Customers shouldn’t expect any major side effects as a result of taking HeartGreens, although at least one customer has complained of heartburn. The use of Wheatgrass can cause heartburn issues for some consumers, along with the possibility of experiencing nausea, loss of appetite, and constipation. The inulin content may also cause mild stomach issues.
How Much Does HeartGreens Cost?
Prices for HeartGreens vary considerably depending on the retailer. The most expensive way to purchase this product is by buying a single 150g tub. On both Amazon and the official HumanN website, this option will set customers back $39.95 plus $8.95 in shipping and handling.
Customers on the official website do have slightly more choice in terms of bulk buying. A purchase of 3 boxes costs $79.90 and six packs costs $149.90. Autoship programs are also available, with a monthly subscription costing $34.95 per month, and a 3-month subscription costing $69.90 every 3 months. All bulk options on the official website come with free shipping.
Our Verdict On HeartGreens
Like most of HumanN’s products, HeartGreens seems to broadly do what it claims to do. The two most important ingredients (kale and spinach) are good sources of nitrates, which should readily convert to Nitric Oxide when consumed. Customers enjoy the taste as well, which is normally a big challenge for manufacturers trying to make a superfood supplement like this. Customers will also likely enjoy HumanN’s generous 90-day money back guarantee, which helps to ensure that this pricey purchase isn’t overly risky.
We urge readers to remember that the benefits of raising NO levels through supplements may only be felt by those who currently suffer with an NO deficiency or those who are already suffering with cardiovascular issues. Consumers that do fall into this category however should see great benefits from all of HumanN’s products, including HeartGreens.
It’s not all good news however. One major issue is the price, which is unacceptably high when you consider what this product really is: a relatively cheap mixture of some very easily-acquired vegetables. Customers looking to buy this product are likely going to have to fork over $50-$80 to get a taste of it, which just seems to us to be far too much for what is essentially kale and spinach and some other bits thrown in.
Unfortunately, kale and spinach are not even the most nitrate-rich vegetables out there – that distinction falls to arugula, as well as at least 10 other leafy-green vegetables. If readers are really concerned with elevating their NO levels through a healthy diet, we urge them to simply buy the most useful vegetables for far less at the store and make them a normal part of your diet. Product like this are simply unnecessary and expensive when you consider alternatives like these.
We would not recommend HeartGreens to our readers.

HeartGreens is a superfood supplement that claims to support cardiovascular health. This powdered product is designed to be mixed into a smoothie or breakfast drink, and uses a small quantity of stevia to make the taste more palatable. Like many other products offered by the manufacturer, HumanN, HeartGreens has been specially designed to boost Nitric Oxide (NO) production, which is then said to support healthy blood pressure and good circulation.
HeartGreens is produced and sold by HumanN (also known as Human to the power of N), an American supplement manufacturer that was formerly known as Neogenis Labs. Co-founded by an American scientist called Dr Nathan Bryan, HumanN seems to have made the most of its links to the University of Texas, as it draws its formula designs and scientific credential from the University’s research teams and staff. Dr Bryan is also well-known in his field for his existing work and research on the subject of Nitric Oxide and its effects on the body. The company can be contacted via the contact details supplied on the official website.
How to Take HeartGreens
The directions for use are as follows:
Mix 1 scoop (5g) thoroughly with 4-6oz of water. For optimal blood pressure support, take 2 scoops daily. Store in cool, dry place. Consume within 45 days of opening. Do not exceed two 5 gram servings in a 24 hour period.
- Price is extremely high, especially when not purchased in bulk
- The ingredients selected do not appear to be the most effective ones out there
- Ingredient quantities not listed
What Does HeartGreens Claim To Do?
Like most other HumanN products, HeartGreens aims to boost Nitric Oxide production in the body, a process which then leads to healthy blood pressure levels and good overall cardiovascular health. Along with the benefits of improved circulation, customers are also told to expect improvements to energy levels whilst taking this product.
Does HeartGreens Work?
The main flagship ingredients in this product are kale and spinach, two leafy greens that have indeed been associated with boosting the body’s NO levels through their own rich source of nitrates. Spinach and kale are far from the richest sources of nitrates in the world of vegetables (that prize goes to arugula), but they contain enough to probably make an appreciable difference if this product is used regularly. Most other ingredients have only been linked tenuously with boosting NO production, but will all probably work well together to maximise the benefits of taking the product.
Readers should note that the associated benefits of this (such as lowering the risk of heart disease etc.) will only take place for customers that suffered from cardiovascular issues, or from lowered NO levels beforehand.
What Are The Ingredients of HeartGreens?
The ingredients included in HeartGreens are listed below. Readers should note that the ingredient quantities are not listed on the product or on the official website, which can make it difficult or impossible to estimate how effective the mix is overall.
- Kale: This vegetable is widely regarded as a superfood, as it contains significant levels of numerous vitamins and minerals, including vitamin A, vitamin C, vitamin B6, folate, calcium and iron; some of these nutrients are most commonly found in meat or dairy, and so are more difficult to source from a vegan diet. Kale is also a good source of nitrates (which can be readily converted into NO to improve heart health), although it doesn’t rank particularly highly amongst the leafy greens. Source, Source
- Wheat Grass: Another highly concentrated source of nutrients, including vitamin A, vitamin C, vitamin E, iron, calcium, magnesium and amino acids. It also contains some chemicals naturally that may have anti-oxidant and anti-inflammatory properties. Source
- Barley Grass: Barley Grass is thought to help with lowering cholesterol, providing an antioxidant effect and helping to lower the threat of cancer. Source
- Spinach: Spinach has a range of antioxidant properties. It also helps to prevent cancer, cardiovascular disease, age-related macular degeneration, and the degeneration of the immune and neurological systems. It is also a major source of dietary nitrates, which can help to boost NO levels. Source
- Inulin: This prebiotic is often used to improve gut health, although some studies have indicated that it might boost NO synthesis under the right circumstances. Source
- Magnesium Ascorbate: This is a non-acidic form of Vitamin C. Vitamin C helps with protecting cells and healing wounds and is necessary for maintaining healthy connective tissue. Although Vitamin C can be linked positively to cardiovascular health, supplementation is not generally thought to be useful as a means of reducing the risk of heart disease. Source
- Monk Fruit Extract: This interesting South-East Asian fruit is typically used as a healthy sweetener, comparable to stevia. Source
- Stevia: Stevia is a natural sweetener that contains a fraction of the calories and health risks associated with sugar. Source
- Spirulina: Spirulina is a blue-green algae that contains a range of natural vitamins and minerals. Almost all claims made about it are currently unsubstantiated, although it is thought to synthesis/release Nitric Oxide. Source
- Licorice Root Extract: Liquorice can be used to treat digestive problems and can cause water retention. In certain Chinese herbal medicine formulations, liquorice has sometimes caused an increase in NO production. Source
- Lemon Flavor
- Malic Acid
- Guar Gum
Does HeartGreens Have Any Side Effects?
HeartGreens is unlikely to come with side effects for most. Wheatgrass can sometimes cause nausea, appetite loss, heartburn, and constipation on occasion (with at least one customer complaining of heartburn as a result of this product’s wheat content).
The inulin content may cause mild stomach issues for some, although this is rare. Liquorice has been associated with numerous side effects as well, although the quantity included in this mix is likely to be too low to cause issues. If consumed to excess over a long period of time, liquorice can cause weakness, headaches, water retention, a decrease in libido, organ damage, and high blood pressure.
Do not exceed recommended serving size. Use only as directed. Not intended for use by persons under 18 or by those with a serious medical condition. Do not use if pregnant or nursing. Please consult your physician before using this product.
Are There Any Customer Reviews For HeartGreens?
HeartGreens is not as popular as other HumanN products like Neo40, and has far fewer customer reviews to check. Those that we could find were almost all positive, with one dissenting customer complaining of side effects (that are arguably more the fault of the customer on this occasion than the product itself).
HumanN continues to impress, taste was simple enough, much, much better than greens I have tried in the past. I take this in the mornign with my smoothies, easier than mixing in greens and the boost before lunch is great.
This tastes like fruity pebbles to me, without being too sugary sweet. By far the best greens product I’ve had recently, without the bitter aftertaste. There is some fiber/greens that don’t fully dissolve, but I feel great getting an extra boost of greens in my daily diet.
My lovely sister knows that I hate to eat cooked vegetables…so she gave me this product. My goodness, I’m not only feeling better — but things seem to be improving all around. Taste is not bad — I mix it with my fiber drink to get a really good dose of health!
Should have read the ingredients has wheat grass and one other grain item. Gave me terrible heartburn. Don’t buy it you can’t have wheat.
Does HeartGreens Offer a Money-Back Guarantee?
All products purchased from HumanN are protected by an impressive 90-day money back guarantee. If dissatisfied, customers are invited to contact the customer service team to receive a Return to Manufacturer Authorization (RMA) number. Full refunds (minus shipping and handling) are granted for used or unused packages, as long as they are returned in “good condition” in their original packaging. Customers must remember to write their RMA number clearly on the returned package to receive their refund.
Where Can I Buy HeartGreens?
HeartGreens is available to buy from the official HumanN website and from Amazon. A single 150g tub of Heartgreens costs the same from both retailers ($39.95, with an additional shipping and handling cost of $8.95).
Those purchasing from the official website can also unlock significant discounts when purchasing in bulk. Three tubs of HeartGreens costs just $79.90 with free shipping and handling, and six tubs costs $149.90 (also with free shipping and handling). Customers of the official website can also sign up for autoship programs if they wish, with monthly programs costing $34.95 per pack and 3-month programs costing $23.30 per pack.
