Feed your heart with heartgreens

You’ve likely heard of popular heart-healthy diets like DASH, and know that a key component is eating a lot of vegetables. But why? We now know that diets like the DASH diet work for numerous reasons, but one overlooked reason is the dietary nitrate found in certain green leafy vegetables, such as kale or spinach, that turns into nitrite and Nitric Oxide in the body.

Premium greens like Kale & Spinach used in HeartGreens are sourced for consistent levels of dietary nitrates to support Nitric Oxide production.

HeartGreens makes it quick and easy to get your daily source of nitrate from greens with ingredients like Kale, Spinach, Spirulina, Barley Grass, Wheat Grass

A single serving of HeartGreens provides the dietary nitrate equivalent of 5 servings of veggies.

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 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.

Our Gold Standard

All of the greens sourced for HeartGreens have gone through standardized testing to ensure a consistent level of dietary nitrate. We also have a team of scientists behind it that understand how to effectively metabolize nitrate and nitrite in the body to produce Nitric Oxide.

We began with world-class, patented research solutions centered around Nitric Oxide restoration--the key to healthy circulation and heart health.

We maintain rigorous growing standards that ensure we harvest dark, leafy greens that are sourced for consistent levels of dietary nitrate to support N-O production.

We use only non-GMO kale and spinach grown here in the U.S., in rich, carefully cultivated soil.

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.
