cardio greens

In a world filled with processed foods, environmental toxins, and daily stressors, giving your body a daily dose of nutrient-dense, plant-based superfoods is one of the most powerful choices you can make—especially for your heart.

Cardio Greens is a physician-formulated, organic greens drink that delivers the best of land and sea, root and leaf, all in one unsweetened scoop. Free of sugar, stevia, monk fruit, erythritol, and artificial flavors, it’s built for serious heart support without compromising your metabolism, gut health, or taste integrity.

Let’s explore what makes Cardio Greens so powerful—and why unsweetened is the only way to go.


🌿 The Benefits of a Reconstituted Organic Greens Drink

Daily greens drinks support your cardiovascular health in multiple ways:

✅ Alkalize and Balance Your Body

Modern diets are too acidic. Greens help restore pH balance and mineralize your tissues, supporting energy, immunity, and bone health.

Journal of Environmental and Public Health (2012) found alkaline diets reduce muscle wasting and improve cardiovascular markers.

✅ Boost Nitric Oxide for Better Blood Pressure

Greens like spinach and beet tops are rich in dietary nitrates that enhance nitric oxide production—essential for vasodilation, circulation, and oxygen delivery.

Hypertension (2008) demonstrated nitrate-rich vegetables lower blood pressure significantly.

✅ Combat Oxidative Stress

Antioxidants in greens, fruits, and vegetables neutralize free radicals that damage blood vessels and accelerate aging.

A Clinical Nutrition (2011) study showed that vegetable powders reduced DNA damage and increased antioxidant capacity.

✅ Support Detoxification

Ingredients like chlorella and dandelion help bind to heavy metals and support liver detox, essential for heart and metabolic health.

Nutrition Research and Practice (2014) confirmed that chlorella improves detoxification and reduces heavy metal burden.

✅ Improve Gut Health and Inflammation

Greens feed good gut bacteria, support digestion, and regulate systemic inflammation—a major driver of cardiovascular disease.

Frontiers in Nutrition (2020) showed leafy greens increase microbial diversity and gut-derived anti-inflammatory compounds.


❤️ What’s Inside Cardio Greens? A Formula Designed for Heart Health

🌱 Grasses Blend

Wheatgrass, Alfalfa Leaf, Barley Grass, Oat Grass
These chlorophyll-rich grasses are loaded with enzymes, magnesium, potassium, and antioxidants that:

  • Lower blood pressure
  • Improve oxygenation
  • Bind toxins and acids
  • Reduce inflammation

🍏 Antioxidant Fruit Blend

Apple, Acai, Acerola, Cranberry, Pomegranate, Lycii (Goji) Berry
These heart-protective fruits are rich in:

  • Anthocyanins to reduce plaque formation
  • Polyphenols for endothelial health
  • Antioxidants to combat arterial stress

Pomegranate, in particular, has been shown to reduce carotid artery thickness and improve blood flow in multiple human trials.


🥬 Vegetable Blend

Cabbage, Dandelion, Parsley, Spinach, Kale, Broccoli, Cilantro, Broccoli Sprout
A cruciferous and leafy medley that provides:

  • Natural nitrates for nitric oxide production
  • Sulforaphane to reduce oxidative stress
  • Vitamin K1 to support healthy clotting and arterial flexibility
  • Detox support for better cholesterol metabolism

🌊 HydroFoods Blend

Chlorella, Spirulina, Dulse, Kelp, Fucoidan Extract
Sea-based nutrients provide:

  • Trace minerals like iodine and selenium
  • Blood-purifying and anti-inflammatory benefits
  • Cholesterol-lowering and thyroid-regulating properties
  • Fucoidan, shown to have anti-coagulant and anti-hypertensive effects

🌾 Fiber + Fatty Acids

Chia Seed, Flax Seed, Nopal Cactus

  • Provide soluble fiber to bind bile acids and lower cholesterol
  • Rich in omega-3 ALA to reduce vascular inflammation
  • Help stabilize blood sugar and insulin response—critical for heart health

🦠 Probiotic Blend

Lactobacillus gasseri, Bifidobacterium bifidum, Bifidobacterium longum
Your gut influences every aspect of your cardiovascular health. These strains:

  • Lower blood pressure
  • Improve lipid profiles
  • Support weight and insulin balance
  • Increase production of short-chain fatty acids (SCFAs) that reduce inflammation

🚫 Why No Sweeteners? Even the Natural Ones

Many greens powders—especially those marketed as “delicious”—add sweeteners like:

  • Stevia
  • Monk Fruit
  • Erythritol
  • Sucralose or Aspartame
  • Even cane sugar or agave

But sweeteners, even zero-calorie ones, can:

  • Disrupt the gut microbiome
  • Trigger cravings
  • Alter insulin sensitivity
  • Confuse the brain’s satiety signals

Nature (2014) and Cell (2022) studies show non-nutritive sweeteners change microbiota and impair glucose metabolism.

Your body doesn’t need sweet—it needs real nutrients. Over time, your taste buds adapt, and the pure, earthy flavor becomes refreshing and grounding.


💚 The Bottom Line: Let Greens Be Greens

Cardio Greens is more than a multivitamin—it’s a daily ritual for vibrant health, longevity, and heart protection. It supports:

  • ✅ Healthy blood pressure
  • ✅ Clean arteries
  • ✅ Resilient blood vessels
  • ✅ Efficient detoxification
  • ✅ Gut-brain-heart synergy

All without the sugar. Without the gimmicks. Without the junk.


Ready to fuel your heart with real nutrition? Drink Cardio Greens daily—and experience the difference a clean, unsweetened greens drink can make for your energy, vitality, and cardiovascular resilience.

(Pairs well with Heart Beet and Vessel Support for a triple combo that is the perfect attack on heart disease)

About Dr. Lauren Lattanza NMD, FACC

Dr. Lattanza Office Visit with Patient

As a Naturopathic Physician, I am trained to treat the whole person and get to the root cause of disease.

I went to Arizona State University where I graduated with a bachelor’s degree in psychology with a depth in physiology and minor in Spanish. After my undergraduate degree I was working on prerequisite classes towards medical school, which is when I came to learn that my values identified best with the principles of naturopathic medicine. I knew that I wanted to help patients identify the causes of disease and be able to offer treatments which would improve their health rather than simply treating symptoms.

I dedicated the next 4 years to the Southwest College of Naturopathic Medicine in Tempe, Arizona where I attained my Doctorate of Naturopathic Medicine. I served as Class President all 4 years, Board of Trustees – Student Trustee, spoke as the Club President for our branch of Toastmasters, and was voted by my peers and attending physicians to earn the Outstanding Leadership Award for the Class of 2020. Throughout medical school I took it upon myself to work alongside MDs, DOs, chiropractors, and functional medicine practitioners in addition to naturopathic physicians.

As a Spanish speaking student, I was able to volunteer with community clinics around Phoenix and provide free healthcare to low-income families. Due to this combined exposure, I came to find my passion in treating cardiometabolic and digestive disorders that are all too common, yet largely preventable. I took the opportunity to learn the broad spectrum of healthcare so I can ensure that I am able to provide my patients with the best options.
