Dr. Steven Gundry is a cardiologist,heart surgeon, researcher, and author. He has published over 300 studies, journals, and books; and is a world-renowned speaker on the topic of weight loss, nutrition, and heart health.

As Head of Cardiothoracic Surgery at Loma Linda University for 16 years, Dr. Gundry patented nine lifesaving cardiac devices – including the “Gundry Retrograde Cardioplegia Cannula” – still a gold standard in open-heart surgery today. He also helped to pioneer pediatric heart transplants, cross-species heart transplants, and robotic surgery.

For his entire career, Dr. Gundry has been faced with chronically sick, overweight patients. But what he discovered suddenly forced him to change his trajectory. When an ‘inoperable’ patient walked into his office after completely reversing his clogged arteries through diet alone, Dr. Gundry began researching. Could it be that you could fight coronary artery disease using only dietary changes? He discovered it was true by first experimenting on himself. In his first year of trying out dietary theories he developed back in graduate school at Yale University on himself, he lost 70 pounds and reversed his ailments, such as high cholesterol and migraines.

In 2002, Dr. Gundry dramatically left his career in heart surgery to follow a new mission: to improve health, happiness, and longevity –

without surgery – and founded The International Heart & Lung Institute and The Center for Restorative Medicine in California. In 2008, after years of researching how certain foods affect the body, Dr. Gundry compiled all of this knowledge into a book, and published the best-seller, The Diet Evolution.

In 2016, Dr. Gundry launched Gundry MD, a line of online supplements aimed at helping more people get the nutrients they need to prevent disease and find vitality. Then, in 2017, Dr. Gundry released, The Plant Paradox, an evolution of his first book after a decade of research and new findings. The book arms readers with powerful knowledge about food and lifestyle through easy-to-follow studies, success stories, and tasty recipes. It quickly became a New York Times bestseller and a consistent top seller on Amazon.

The Plant Paradox addresses the concept of lectins and how harmful they can be to our health. Lectins are plant proteins found in produce like tomatoes, grains, and soy. Dr. Gundry believes lectins, over time, poke holes in your gut which leads to stomach issues and diseases. This is the very reason why Dr. Gundry created, Lectin Shield, a supplement that helps protect the body from lectins’ harmful effects.

How does LECTIN SHIELD work?

Gundry MD Lectin Shield is made up of 9 key ingredients that work together to provide you with full lectin support. Each capsule contains:

1. N Acetyl D-Glucosamine
A wheat-lectin blocker that binds to lectins that have been associated with joint problems. It’s also a common ingredient in joint health supplements.

2. Bladderwrack
Bladderwrack is a potent seaweed that’s been shown to bind to those nasty, inflammatory lectins. But it also has wonderful antifungal properties, especially against Candida yeasts.

3. D-Mannose
This natural compound binds to specific lectins in legumes – like peanuts, beans, and lentils – while also being a natural antibacterial.

4. Okra Extract
Okra extract is a concentrated source of polyphenols, which are powerful antioxidants. But it’s also full of raw polysaccharides (RPS), which can bind to multiple lectins. As a bonus it has natural anti-fatigue properties.

5. Mucin (Sialic Acid)
Sialic acid binds to multiple lectins, like those found in wheat and many types of berries.It also helps to form a slippery barrier that makes it impossible for lectins to stick to your digestive tract.

6. Sodium Alginate
A natural fiber that acts as a “fecal bulking agent” and can help to keep you regular.

7. Vegetable Peptase
Lectins can inhibit peptidase, a very important enzyme that breaks down proteins in food. Adding vegetable peptase to your diet can assist in protein digestion and hinder the effects of lectins.

8. Methylsulfonylmethane (MSM)
MSM can be powerful in reducing joint pain — especially when combined with N-Acetyl D Glucosamine, listed above.

9. Larch Arabinogalactans
Derived from the Larch tree, this compound nourishes and strengthens your gut lining. A stronger gut lining means better protection against lectin damage.


Gundry MD Lectin Shield has been formulated with all-natural ingredients. It should therefore be safe for daily use by most people. But of course, everybody – and every body – is different.

Lectin Shield should be used with caution if you suffer from a shellfish allergy or are concerned about excess iodine in your diet. N Acetyl D-glucosamine is an extract from the shells of shrimp and other shellfish, while bladderwrack seaweed contains natural concentrations of iodine. As with any new supplement, it’s recommended that you consult your physician before taking Lectin Shield if you have any concerns.
