Lectin Shield

Lectins are a protein present in many plant-based foods we eat. They can interfere with your digestion, energy, and overall health. Lectin Shield is a unique blend of potent compounds designed to help your body eliminate these toxic proteins.


  • Promotes regularity and pleasant bathroom visits
  • Helps reduce feelings of gas and bloating
  • Aids against out-of-control food cravings

Suggested Use

Take 2 capsules, twice a day, with 2 of your largest meals.

What’s in Lectin Shield?

Product Description

This groundbreaking new formula was created to offset the discomforting effects of proteins commonly found in plants that make them harder to digest. These foods pervade the typical American diet and it can be difficult to maintain a completely lectin free diet. This is where Lectin Shield comes in. Lectin Shield works to support your body from a pile-up of lectins and to promote full-body comfort.

  • Supports intestinal health.
  • Helps reduce instances of gas and bloating.
  • Helps curb cravings for lectin foods and encourages digestive strength.


The 9 potent ingredients in Lectin Shield act together to give your body full anti-lectin support making it easier for you every time you eat lectin foods.

Several of the components found in Lectin Shield help counteract the distressing effects of lectins. Some of the ingredients even have useful antioxidant and anti-fatigue properties.

Simply take two capsules, twice a day, with two of your largest meals. That’s all you have to do to start easing the discomfort of digestion.


Now, let’s look a little closer at each of the 9 ingredients in Lectin Shield and how they work on certain foods containing lectins…

N Acetyl D-Glucosamine

N Acetyl D-Glucosamine binds to harmful lectins from wheat.1 Since wheat lectins have been associated with joint problems, this wheat lectin blocker is also a popular ingredient in joint health supplements.2


Bladderwrack, a powerful seaweed, has been shown in studies to bind to dangerous, inflammatory lectins.3


D-Mannose is a potent natural compound that binds to specific lectins in legumes, a lectin rich food.4

Okra (Fruit)

Okra is your source for raw polysaccharide (RPS), a powerful compound that binds to multiple toxic lectins.7 As a concentrated source of polyphenols, okra extract has been shown to have powerful antioxidant and anti-fatigue properties.8


Mucin helps to form a slippery protective barrier inside your digestive tract.9 Not to mention, the sialic acid in mucin binds to multiple sources of foods containing lectins, including those found in wheat and several types of berries.10

Sodium Alginate

When you’re dealing with lectin-based digestive problems, sodium alginate can be your best friend. It also acts as a “fecal bulking agent,” which can help make bathroom visits much more pleasant and less frantic.11

Vegetable Peptase

When you eat lectins they inhibit peptidase, an important enzyme your body uses to break down proteins in your food, spelling trouble for your digestive tract.12 So, I’ve included vegetable peptase in Lectin Shield to assist your protein digestion and counteract the digestive effects of lectins.

Methylsulfonylmethane (MSM)

I mentioned earlier that foods containing lectins, particularly wheat lectins, have been tied to joint discomfort.13 MSM has been shown to be a powerful agent for helping to reduce joint discomfort — especially if you use it in combination with N-Acetyl D Glucosamine above.14

Larch Arabinogalactans

Arabinogalactans have been shown to increase butyrate production in gut bacteria.15 Butyrate nourishes your gut lining, which is your first line of defense against lectins and other harmful substances you unknowingly eat.16



These are the main ingredients in Lectin Shield™:

  • N Acetyl D-Glucosamine
  • Bladderwrack
  • D-Mannose
  • Okra 
  • Mucin
  • Sodium Alginate
  • Vegetable Peptase
  • Methylsulfonylmethane
  • Larch Arabinogalactans


Lectin Shield is a powerful formula designed to help ease the effects of consuming harmful lectins and support overall gut health.

The biggest difference between Gundry MD® Lectin Shield™ and other gut health supplements is that the ingredients that make up this formula are both 100% natural and pure, and scientifically shown to support your gut health. 

On top of that, it contains zero sugar or artificial sweeteners — unlike many supplements you’ll find on the market today.

Not only is Lectin Shield™ a one-of-a-kind gut-health supplement, but it’s a 3-1 formula designed to support intestinal health, help reduce instances of gas and bloating, and help discourage cravings for unhealthy lectin-filled foods.


Gundry MD™ Lectin Shield is for anyone who wants help achieving…*

  • Easy, regular, comfortable digestion
  • More easily controlled “junk” cravings 
  • More comfortable, mobile joints

*Every individual is unique. As such, your results may vary. 

Gundry MD™ Lectin Shield is a healthy supplement designed to support your body naturally. It is not a substitute for prescription medication. It is highly recommended that you consult with your own health care provider before beginning any new program.


Every single batch of Lectin Shield capsules consists of 9 naturally-derived ingredients. To protect the integrity of this lectin blocker, Lectin Shield is packaged in an easy-to-close, high-grade amber glass bottle. This helps keep the supplement fresh and potent.

Lectin Shield is always tested by a third-party lab for quality and purity. And don’t forget, this powerful formula has absolutely no sugar and is manufactured in a “Good Manufacturing Practice” certified facility. When you rely on the pure ingredients in Lectin Shield, as well as avoiding lectins whenever you can, you’ll be taking huge steps to support your overall health.


Lectin Shield was designed as an easy-to-swallow capsule. For maximum effectiveness, it is recommended that anyone taking Lectin Shield take two capsules, twice daily. That means anyone taking Lectin Shield should take four capsules every single day.

For best results, take Lectin Shield with your two largest meals of the day and remember that consistency is key to experiencing the best results.  



When it comes to results, many of the people who take Lectin Shield report a distinct improvement in gut health and digestion within just the first few days of adding the supplement to their health regimen.*

For many users, the most dramatic results will be noticed over the course of 2-3 weeks. Please use it as directed for the best results. And don’t forget — consistency is key! 

*Results not typical. All individuals are unique; your results can and will vary.



Gundry MD Lectin Shield was created for optimal all-natural purity. It is effective to use daily for the vast majority of people.

However, it is strongly suggested that you speak with your healthcare practitioner before beginning any new regimen — including the decision to try Gundry MD™ Lectin Shield.

It’s important to note, this dietary supplement contains N Acetyl D-glucosamine. This ingredient is extracted from the shells of shrimp and other shellfish. Lectin Shield also contains bladderwrack, which houses natural concentrations of iodine. If you happen to have any kind of shellfish allergy or you are concerned about excess iodine in your system, please take caution using Gundry MD™ Lectin Shield, and speak with your healthcare provider before you do.


While Total Restore is designed to support and nourish your gut lining, it has a unique power to help you to “flush out” toxins in your bloodstream. Lectin Shield is designed to help “block” these toxins from entering your body in the first place. The two formulas are extremely compatible and can therefore be used simultaneously for accelerated results.


No two bodies are alike. So even though many users rave about the incredible changes they are experiencing with Lectin Shield, there may be some very rare cases with fewer results or customers who simply don’t like the formula.

Because your satisfaction is our primary concern, Lectin Shield comes with Dr. Gundry’s personal 90-day guarantee. If for any reason you are unsatisfied within 90 days of use, you can return your bottles for a full refund of your purchase price, no questions asked.

You can read reviews from Lectin Shield lovers below… and you can read all reviews about Gundry MD here.


I formulated Gundry MD® Lectin Shield™ with these 9 cutting-edge ingredients specifically to…

  • nourish your gut lining (helps prevent “Leaky Gut”)
  • form a protective barrier in your GI tract
  • help make bathroom habits more “regular”
  • support your immune system
  • help your body process protein for energy
  • reduce your overall appetite
  • help relieve joint discomfort

…and help you get the body you want, the energy you deserve, and the vitality you know is inside – just waiting to break free*.
*individual results may vary

For many years now, understanding the effects of lectin toxicity has been a passion project of mine. I’ve seen the damage lectins have done to my patients firsthand – and I know what’s at stake.

But since I developed this product and began encouraging a lectin free diet, I’ve seen so many patients at my clinic experience incredible breakthroughs in weight loss, heart health, and immune function.

I’d like to let you hear from just a few real Lectin Shield users…

“…. Within 2 weeks of using Lectin Shield I have been able to walk 3-4 miles and I have noticed the increase in energy. I almost feel like my overall attitude has changed as well. I can tackle more house chores and don’t have to nap for hours at a time. If this is just cutting the surface to better health down the line, these products will be staples in my home like toilet paper and toothpaste, a necessity not a want.” *
— Christy V.

I haven’t felt this good in maybe 10 years. I wake up feeling refreshed and full of energy, sleep so much better, I have lost 5 lbs (with) no dieting… The past 5 weeks have me feeling incredible. Thank you Dr. Gundry for this super product.” *
— Brian B.

I can tell the difference, if I forget to take (Lectin Shield), my digestive tract is very upset. When I do take it, I feel satisfied and full, no digestive issues. Thank you Dr. Gundry for helping those of us who thought our days of sharing a meal in public was over.” *
— Julie Anne M.

Based on extensive user group data – as well as reviews from hundreds of verified customers – the results are clear…

Lectin Shield helps you suppress your appetite, maintain a lectin free diet, support your digestive system and reduce those feelings of occasional joint aches.

In fact, Gundry MD Lectin Shield is the most significant medical innovation I’ve developed to date.

I feel very strongly about that, and now I want to put it in your hands.

Problems With Gut Health? Look To Gundry MD™ Lectin Shield

  Lectins are harmful plant-based proteins hunting for sugar in your gut, bloodstream, and nervous system. Once they find that sugar, they cling to it like barnacles on a boat. This would be no big deal if they clung peacefully. But when lectins invade, they poke holes in your gut allowing harmful pathogens to enter and destroy the good-for-you gut flora in your gut microbiome. Lectins can cause big trouble — digestive issues and discomfort, zapped energy levels, irregular bowel movements, and more. Gundry MD™ Lectin Shield is a one-of-a-kind dietary supplement designed to help your body eliminate these toxic proteins and support your overall health and well-being.

A Lectin Blocker That Sets The Bar High: Gundry MD™ Lectin Shield Benefits

  Each and every lectin you end up consuming has the potential to damage your gut health. The unique blend of potent compounds in Gundry MD™ Lectin Shield works to help eliminate lectins and their harmful actions so they won’t take such a heavy toll on your system. Gundry MD™ Lectin Shield is formulated to promote the following health benefits: – Provide nourishment to the gut lining * – Encourage regularity and pleasant bathroom visits * – Support intestinal health * – Support immune system * – Help ease feelings of gas and bloating * – Aid against out-of-control food cravings * – Help ease joint discomfort * *Individual results can and will vary.

  1. N Acetyl D-Glucosamine
  2. Bladderwrack

  5. Mucin 
  6. Sodium Alginate
  7. Vegetable Peptase
  8. Methylsulfonylmethane
  9. Larch Arabinogalactans

First Line of Defense: Avoid These High Lectin Foods With Gundry MD™ Lectin Shield

  Avoiding lectins is as important as blocking them once you consume them. In concert with using Gundry MD™ Lectin Shield, it is highly recommended that you also try to avoid the following lectin-heavy foods:   Legumes – Legumes have a very high lectin content. This includes foods such as beans, peas, lentils, and peanuts. Grains – Grains are full of damaging lectins like agglutinin. Eliminating grains is one of the primary tenets of a lectin-free diet. Nightshade vegetables — Nightshade vegetables and fruits include tomatoes, peppers, eggplant, and potatoes. Not only are they chock-full of lectins, but nightshades contain natural pesticides (glycoalkaloids) that can tank your efforts to keep healthy. Casein A1 Dairy Products – The casein present in most dairy products contains harmful lectins which can cause digestive discomfort. Opt for dairy products containing casein A2 instead. You can find them in many grocery stores today. 

Premium Quality, Honest Purity, And High-Potency

  Gundry MD™ Lectin Shield contains only 100% natural and pure ingredients. Each bottle of Gundry MD™ Lectin Shield is manufactured in the United States of America and contains a 30-day supply. Packaged for freshness, Gundry MD™ Lectin Shield comes in a top-quality amber glass bottle. Each batch of Gundry MD™ Lectin Shield is third-party tested for ingredient strength and purity.

  Many Gundry MD™ Lectin Shield users are quick to take advantage of the chance to acquire multiple bottles of the lectin blockers at a steep discount. The most popular order for Gundry MD™ Lectin Shield users is the 3-bottle option, which we recommend. Many longtime, regular users or Gundry MD™ Lectin Shield prefer to opt for the 6-bottle package. This will give you the best price, as well as ensuring you’re stocked up. After all, the best results come with consistent use, and the 6-bottle package will give you plenty of Lectin Shield so you can stick to your new routine.

But no two bodies work in the same way, and some bodies react differently to the exact same compounds.

Simply send the unused portion back within 90 days and you will receive a full refund of your purchase price— no questions asked. Your satisfaction is our first priority.

    5 out of 5 Using as needed


    I use Lectin Shield when I know I will be eating some food that is definitely not good for my gut. If I don’t use it, I seem to get more gas which stays up high in my stomach area and I seem to have the bloating for hours. With Lectin Shield the food digests without leaving all the gas. I don’t have to undo my bra hook to feel better. I had indigestion for years. Now by using your product and by knowing what I should eat, by reading your books, there isn’t the terrible result of not being able to sleep at night due to the indigestion. There is no knowing how all your products and advice have benefited me, but I trust in your research and knowledge. Thank you Dr. Gundry.

    I am a natural nutritionist and was worried about actually taking additional supplements. To my surprise thus far I have made no adverse reactions. I am actually experiencing less bloat and hoping that with continued efforts I maybe able to enjoy lectin foods (which I love and eat daily) with more ease!

    The Lectin Shield is well engineered and perfect. I share the Lectin results with relatives and fiends. Received zero complaints just
    “Thank you!” and compliments. My weight has stabilized ever since I joined the many people you’ve helped. Thank you Dr. Gundry

    Olivia Allnutt

    My husband and I try to avoid the ‘no list’ foods, however we also travel a lot for work, so having the Lectin Shield with us when we can’t prepare all our meals is very helpful!

    I use it for those days when “my eyes see outside the list of allowed food”. I find there are no consequences when taken with the LECTIN SHIELD. Very satisfied.

    5 out of 5 Feeling like I should


    I started taking lectin shield and prebio thrive at the same time. I had a day or 2 of my body getting adjusted but then I started to feel less bloated and less uncomfortable feelings. I especially noticed that my digestive system is working better. I was having some issues before and now I’m not so I’m very happy about that.

    5 out of 5 Lectin Shield great for my life


    With a busy life style, it’s hard to eat right all the time. And to have a Lectin free diet is impossible for me. So it’s nice to know that with Lectin Shield I can still balance my digestive system.
