    Lectins: Plants’ Natural Defense

    Imagine finally being in control of your appetite and eating your favorite foods without worrying about digestive discomfort, embarrassing gas, or frequent trips to the restroom. Lectin Shield can help you protect your body against dangerous, hidden “anti-nutrients” that put your health at risk: plant lectins.

    Turns out, lectins are a plant’s natural system of defense. That’s right, they’re designed to harm you so you won’t eat them again. They can even paralyze the insects that eat them!1,2 Not only that, but lectins are part of the reason even a “healthy” vegetarian diet can cause weight gain and digestive issues.

    The bottom line: No one has addressed this issue — and it’s the biggest problem in the American diet today. Carbs are not the problem. Sugar isn’t either. And it’s not fast food, artificial sweeteners, preservatives, fat, or even high-fructose corn syrup. Lectins are what’s making America fat, sick, and tired. But, there’s a shield for lectins.

    A One-of-a-kind Product

    Lectins wreak havoc on your system by sticking to certain cells in your body. But there are some natural compounds that can actually block plant lectins and keep them from sticking to your cells… so they can’t do their dirty work!3,4 These natural compounds are monosaccharides and oligosaccharides, and they can be found in a number of natural sources.5

    And, since lectin-rich foods are spread throughout the typical American diet, it’s not easy to avoid them completely. That’s where Lectin Shield comes in.

    Gundry MD Lectin Shield was created to neutralize the toxicity of dietary lectins (the proteins plants produce that make them harder to digest) and provide you with a simple, at-home solution to the lectin dilemma.

    Lectin Shield works to protect you from lectin overkill, and it supports optimal wellness. By blocking the lectins in your diet, the formula is constructed to help…

    – Control your cravings for unhealthy foods
    – Reduce gas, bloating, and digestive discomfort
    – Promote better nutrient absorption
    – Support your immune system
    – Strengthen the walls of your gut
    – Manage your appetite so you can maintain a healthy weight
    – Improve your joint and muscle strength
    – Boost your energy
    – Make bathroom habits more “regular”

    Foods High in Lectins

    Now, there is a slew of high-lectin foods out there. And some of the foods you’ve been taught are traditionally the healthiest are some of the worst offenders. Check out this list of lectin-rich foods that should ultimately be eliminated from your diet:

    – LEGUMES — that means all beans, lentils, peas, peanuts, soybeans & all  soy products, and more.
    – GRAINS — wheat, rice, corn, barley, oats, rye… ALL grains.
    – NIGHTSHADES — potatoes, tomatoes, eggplant, and every type of pepper.
    – Almost all seeds from American plants.
    – Fruits & vegetables with lots of seeds — squash, zucchini, cucumbers, melons, etc.

    Plus, lectins can also be found in milk, dairy products, and eggs.

    That’s a lot of food! Even if you’re a lectin-eliminating superstar, you’ll need some help. So, let’s look inside Lectin Shield…


    I believe Gundry MD Lectin Shield will give you real relief and make a significant difference in your body’s fight against lectins. However, there might be a small number of people who don’t find Lectin Shield as helpful as they’d like.

    That’s why every bottle of Lectin Shield is backed by my 90-day guarantee. If, for any reason, you don’t get exactly what you’re looking for from Lectin Shield, just return your bottles, empty or full, for a full refund — no-questions-asked.

    Nine Knockout Safe and All-natural Ingredients

    The following nine potent ingredients combine to make Lectin Shield. Together, they bind to and block plant-lectins, providing real lectin defense for your body… taking the pressure off and allowing you to indulge in some of your favorite foods.

    A few of these ingredients work double-time — binding to dietary lectins so they can’t attach to your body, and counteracting the upsetting effects of lectins. And quite a few of the compounds in Lectin Shield possess antioxidant and anti-fatigue abilities.


    Supplement Facts

    Lectin Shield Supplement Facts

    N Acetyl D-Glucosamine

    N Acetyl D-Glucosamine binds to wheat germ agglutinin — the harmful lectins from wheat have been associated with joint problems.6


    Bladderwrack seaweed binds to inflammatory lectins and has properties that work against Candida yeasts.7,8


    D-Mannose is a natural compound that blocks the lectins in legumes, including peas, beans, lentils, peanuts, and alfalfa.9

    Okra (Fruit)

    Okra supplies raw polysaccharides to bind to toxic lectins.10 With concentrated polyphenol content, okra extract possesses antioxidant and anti-fatigue properties.11


    Mucin helps form a slippery barrier inside your digestive tract so lectins can’t hold on.12 And the sialic acid in mucin binds to many dietary lectins — especially wheat and berry lectins.13

    Sodium Alginate

    Sodium Alginate provides fecal bulking power… which can make bathroom visits more pleasant and less stressful.14

    Vegetable Peptase

    Vegetable Peptase Certain types of lectins inhibit peptidase, which your body needs to break down protein.15 The vegetable peptase in Lectin Shield will help you digest useful protein.

    Methylsulfonylmethane (MSM)

    Methylsulfonylmethane (MSM) has been shown to help reduce joint discomfort — especially when used with N-Acetyl D Glucosamine.16

    Larch Arabinogalactans

    Larch Arabinogalactans can increase butyrate production in your gut bacteria which nourishes your gut lining — the first line of defense against lectins.17,18

    All you have to do to start easing the discomfort of poor digestion is take two capsules, two times a day (preferably with your largest meals).

    A Word from Dr. Gundry…

    For years, 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.

    Since I developed Lectin Shield, I’ve seen so many patients experience incredible breakthroughs in weight loss, heart health, and immune function. And based on extensive user group data – as well as reviews from hundreds of verified customers – the results are clear…

    Lectin Shield can help suppress your appetite, wipe out digestive problems, reduce the feeling of arthritic discomfort in your joints, and help protect your cardiovascular system from meltdown.

    While eliminating high-lectin foods can help start you back on the road to better health, you’ll need a hand protecting your body from lectin damage. That’s why a smart diet — in addition to Lectin Shield — is the way to go when dealing with lectins head-on. Get the body you want, the energy you deserve, and the vitality you know is inside of you waiting to break free.
