Product Details

The first and only greens product focused on healthy BP.


Unlike other “greens” products on the market, HeartGreens was formulated by our team of N-O experts with one goal in mind: to be the first greens product to deliver enough dietary nitrate from food to help produce Nitric Oxide, and make a meaningful impact on your health. In fact, HeartGreens features:

  • The dietary nitrate equivalent of 5 servings of veggies in a single scoop
  • Functional levels of dietary nitrates from kale and spinach, which studies have shown help your body produce the necessary Nitric Oxide to support cardiovascular health and healthy blood pressure levels
  • A superfood formulation that brings science, health and nutrients sourced from REAL foods together
  • A world-class team of food scientists, leading experts in dietetics and nutrition and physiology researchers behind its formulation

Feed your heart.

You’ve likely heard of popular heart healthy diets like the DASH, MIND and Mediterranean diet, and that a key component of each of these diets is eating a lot of vegetables. We now know that those diets work for numerous reasons but one overlooked reason is the dietary nitrate found in green leafy vegetables, such kale or spinach, that turns into nitrite and Nitric Oxide in the body. Nitric Oxide helps promote everything from healthy circulation and blood pressure levels to increased natural energy. But for most of us, it can be hard to find a way to eat the prescribed 4 to 5 servings a day of leafy greens or vegetables. You may not like the taste of greens, or you may simply not have enough time in the day to prepare them! While we encourage you to eat green leafy vegetables, we understand it is not always easy to do so in order to get the necessary dietary nitrate you need from your diet alone.

With ingredients like Kale, Spinach, Spirulina, Barley Grass, and Wheat Grass, HeartGreens makes it quick and easy to get your daily source of nitrate from greens –  a single serving of HeartGreens mixed with water or your morning smoothie provides the dietary nitrate equivalent of 5 servings of vegetables.

Know your Nitric Oxide levels.

Our cardiovascular system relies on Nitric Oxide. So, no matter your age or stage of life, N-O is critical to your health. One of the reasons that diets such as the DASH, MIND or Mediterranean diet are so effective is because they heavily feature dark, leafy greens such as kale and spinach which help provide your body with dietary nitrates.

Dietary nitrate from food feed one of the primary pathways for Nitric Oxide production. And many studies have shown you need twice the amount of dietary nitrate than what a typical diet provides on average per day to help support Nitric Oxide production and healthy blood pressure levels.

So how do you know if you’re getting enough dietary nitrate from diet alone? Our Nitric Oxide Indicator Strips are a simple way to instantly see if you’re getting enough essential dietary nitrate through the foods that you eat on a daily basis to support Nitric Oxide production.


Premium greens standardized to support Nitric Oxide production.

Nitrate can be found in green leafy vegetables, but the amount of nitrate can depend on many factors: the type of vegetable, the soil conditions, the amount of sunlight and rain, and the time of harvest. The amount of nitrate in any given vegetable may vary as much as 30-fold (or 3,000%).  That means you can’t be certain you are getting enough dietary nitrate from your vegetables to get the functional health benefits from just your diet alone. HeartGreens contains premium greens that are standardized to contain the necessary levels dietary nitrate to support Nitric Oxide production.


Nitrate Verified

All of the greens sourced for HeartGreens have gone through standardized testing to ensure a consistent level of dietary nitrate to support Nitric Oxide production.

Our products have a team of scientists behind them.
At HumanN, our scientists understand the mechanisms that effectively metabolize nitrate and nitrite in the body to produce Nitric Oxide. We approach Nitric Oxide holistically.

  • Our team of scientists spans food science, nutrition, physiology and kinesiology
  • Our Chief Science Officers include one of the world’s leading Nitric Oxide researchers and also one of world’s top sports nutrition scientists
  • Our functional foods and supplements are backed by 15 years of research at the University of Texas

We believe in research and clinical studies.  We scour the research and have even conducted seven clinical trials on our own products. Our team of food scientists and nutritionists work together to not only optimize the N-O activating potential in our products, but also formulate to help ensure the body is utilizing the efficiency of the nutrient found in our functional foods.

Customer Testimonials

HeartGreens had a refreshing taste, unlike some of the bottled greens I have had. I typically like to juice my greens, but I have a hectic job with a very full schedule so I often just don’t have time to juice. HeartGreens was great because I could mix it easily with water to quickly get my daily source of greens. It has a nice sweetness to it which makes it much easier to drink. I really like the product.
