About Lectin Shield

Using a combination of nine “dynamically effective,” all-natural ingredients, Gundry MD’s Lectin Shield supplement claims to protect your body from lectin overload, which can lead to digestion problems and inflammation-related diseases.

Instead, by taking two capsules of Lectin Shield twice daily, the company claims you’ll experience:

  • Improved digestion,
  • Reduced gassiness and bloating,
  • Improved regularity,
  • Boosted immune strength,
  • Healthier circulation,
  • Reduced food cravings,
  • Extra protection for your thyroid, skin, & joints, and
  • “Full body wellness,”

… all within just a few days! Even better, they promise you’ll notice more “dramatic” results over the course of two to three weeks.

Despite all these benefits, Gundry MD claims Lectin Shield is completely safe and effective for daily use.

Coming from a highly trained and well-respected surgeon, along with all the scientific terms frequently used on the Gundry MD website, it might be easy to believe that Lectin Shield is a no-brainer. But before handing over your hard-earned money, let’s fully explore this supplement and help you decide if it’s really right for you.

What Are Lectins? Do They Really Cause Disease?

Lectins are a type of protein that acts as a “glue,” binding certain carbohydrate molecules together, without involving the immune system. Although lectins were first discovered in plants (which is also the main focus on the Lectin Shield website), they’re now thought to be widely distributed throughout nature.

Now, it’s important to point out that there are many different lectin families, each of which performs a specific set of functions. For example, in animals, lectins “facilitate cell-to-cell contact”; e.g., they act almost like Velcro by building binding sites on the surface of cells.

This means that animal lectins can be responsible for everything from very specific functions (glycoprotein synthesis) to very broad ones (they play an important role in immune system function). However, the scientific community isn’t quite sure what role lectins play in plants, although they’re thought to act as a deterrent against insects and other threats.

But Wait … Aren’t Lectins Bad For You?

After watching Lectin Shield’s lengthy video, a lot of what you read in the previous section might have come as a surprise. After all, the video certainly didn’t cast a positive light on lectins.

The truth of the matter is that not all lectins are created equal; many can provide us with health benefits (and are even required by the body for proper functioning), while others can do a great deal of harm. For example, ricin is an extremely toxic lectin that can lead to death in very small doses, while raw red kidney beans contain another type of lectin that can lead to side effects similar to food poisoning.

Pro tip: Lectins are found in almost all foods, although legumes (including kidney beans) and grains often contain some of the highest concentrations in nature.

However, not all lectins cause immediate, severe harm to our body. Instead, they may cause much less damage that can accumulate over time into something more serious. Like what?

  • Lectins are though to slow cellular regeneration in the lining of the gut, leading to a potentially severe condition known as leaky gut (keep in mind that there is a lot of controversy surrounding this condition in general, as well as its causes).
  • Since much of our immune system originates in our gut, this slowed regeneration can also cause our body to view these lectins as outside invaders and attack them, leading to inflammation-related symptoms like skin rashes and joint pain.

Is it Possible to Avoid Lectins?

As we mentioned above, lectins are found in most foods. So, unless you’re willing to make drastic changes to your diet, then it’s probably not feasible to avoid them altogether. But why would you, anyway? Remember, the right lectins in the right amounts play key roles in health, and most experts agree that normal lectin consumption poses no serious health risks to humans.

The key here is to monitor how much lectin you consume by properly preparing high-lectin foods in advance. To achieve the biggest bang for your buck, you’ll want to avoid eating raw legumes altogether, and to soak, ferment, sprout, and/or cook them prior to consumption.

Pro tip: Remember the story at the beginning of the Lectin Shield video? The one where everyone became ill after eating a healthy lunch? About the only way this could have occurred so quickly is if they had eating raw legumes, or a variety that’s high in lectins, so it’s more of a marketing tactic than a real-world scenario.

Even if you follow this guideline, what about all the lectin you’re ingesting from other foods? Again, these are necessary for proper bodily functioning, and aren’t thought to cause a great deal of health concerns (if any). Nonetheless, can anything contained in Gundry MD’s Lectin Shield supplement help regulate lectin?

What Ingredients Are Found in Lectin Shield?

According to the product label found on the Lectin Shield website, here’s what the supplement contains:

Will any of these work to counteract the potential side effects associated with lectins?

Although N Acetyl D-Glucosamine and glucosamine sound similar (and are generally derived from the outer shells of shellfish), they have different effects on the body. For example, glucosamine is often used to help treat osteoarthritis, while N Acetyl D-Glucosamine is used to help protect stomach and intestinal lining. However, there isn’t enough clinical evidence available showing that N Acetyl D-Glucosamine is effective for this.

There is mounting evidence showing that sialic acid may help prevent certain types of viruses (specifically, the influenza virus) from attaching to cells and reproducing. However, there isn’t enough clinical evidence to consider it “proven.”

Finally, alginic acid may help inhibit acid reflux, a common symptom of excess lectin intake, although it may not work any better than other bicarbonate-based products you’d find at your local pharmacy.

Outside of these, there appears to be insufficient clinical evidence showing that any of Lectin Shield’s other ingredients will affect lectins (or their side effects).

Potential Lectin Shield Side Effects

In general, most of Lectin Shield’s ingredients should be well tolerated by most users, with the most common side effects being digestive upset and gassiness/bloating.

However, according to WebMD, bladderwrack is listed as “possibly unsafe” when taken by mouth: “It may contain high concentrations of iodine, which could cause or worsen some thyroid problems. Prolonged, high intake of dietary iodine is linked with goiter and increased risk of thyroid cancer.”

Also, due to the N Acetyl D-Glucosamine content, you should not take Lectin Shield if you’re allergic to shellfish.

Despite the somewhat fuzzy clinical evidence supporting the efficacy of these ingredients, how much will Gundry MD’s Lectin Shield cost you?

How Much Does Gundry MD Lectin Shield Cost?

Lectin Shield is available in the following quantities:

  • 1 Bottle: $39.95
  • 3 Bottles: $101.95
  • 6 Bottles: $179.95

Who Is Dr. Steven Gundry? Does His Company Make Other Supplements?

Dr. Steven Gundry is a board certified general surgeon and thoracic cardiovascular surgeon based out of Palm Springs, CA, where he runs the International Heart and Lung Institute. There, he delivers “advanced heart and lung care” for patients looking to “avoid the chronic diseases such as high blood pressure, coronary artery disease, diabetes, cancer and obesity.”

Dr. Gundry is also the founder and director of The Center for Restorative Medicine, with locations in Palm Springs and Santa Barbara, CA. This concierge program is focused on “health and wellness by diet, supplementation, and living well.”

Dr. Gundry’s focus on diet-based health also lead him to write Dr. Gundry’s Diet Revolution: Turn Off the Genes That Are Killing You and Your Waistline, a three-phase plan that aims to help readers overcome obesity-related diseases.

Although Gundry MD is a fairly new company, they have two other products already on the market: Correct + Calm Redness Relief and Vital Reds. We mentioned in our Correct + Calm review that, based on the available clinical evidence, we felt many of the cream’s ingredients might not work as well as the company claimed. However, one HighYa reader has already chimed in and rated it five stars, claiming it gave them “glowing, radiant” skin.

Let’s carry this thought over to the next section as we wrap everything up.

Will Lectin Shield Provide “Comprehensive Anti-Lectin Health Support”?

Despite everything we’ve learned here, when it comes to Lectin Shield, we’re left with an important unanswered question:

Exactly how does Lectin Shield “shield” you against lectins? Does it target and destroy lectins already in your body? Does it help maintain a healthy lectin balance? Or, does the supplement work to counteract some of the negative side effects associated with excess lectin levels?

Regardless of how it works though, there seems to be limited clinical evidence showing that most of Lectin Shield’s ingredients will provide the specific benefits promoted by Gundry MD. And even if they do provide any benefits, it appears they might not be as noticeable as the manufacturer makes it seem.

Despite this, Gundry MD appears to be a completely legitimate company who stands behind their products with a 90-day refund policy. As such, you might not be out more than a few dollars in S&H for giving Lectin Shield a try.

Just remember that, unless you have a habit of eating raw legumes, causing lectin overload—and all the nasty side effects that can come along with it—Lectin Shield might represent a solution to a problem you don’t have.

  • Excellent product

    I was never aware of lectins before, but when I found out what they do to you, I decided to give Lectin Shield a try. I was already on the prebiotic for the last four months. I added the Lectin Shield and now find I can tell the difference already! I'm feeling so much better and have more energy than I had before, plus I'm eating better.

    Bottom Line: Yes, I would recommend this to a friend

  • Lectin Shield insurance

    Although I am following the diet, I wanted to have insurance that lectins were not affecting my leaky gut in any way. It has taken me so long to finally find something I understand and believe is an answer to my problems. Lectin Shield ensures that I have protected myself when I have a meal that may not be completely free of lectins.

    After only three weeks I have a complete blood analysis done by my cardiologist that was so improved he took me off of Atorvastatin. The visit previous he had doubled the dosage. I can imagine what my future tests will be like. I am excited about the direction I am going and believe Lectin Shield is a vital part of the program I am on. I believe I am doing all I can to help myself now.

  • Lectin Shield, wonderful product, improves digestion and weight management!

    I've been starting using Lectin Shield nine months ago with great results, including improved digestion and better weight management. I ran out for a short time and thought perhaps I didn't need it as I was taking some other Gundry supplements as well, but could really feel the difference, especially with digestive issues, stomach cramping and bloating. I highly recommend Lectin Shield, especially for those times when you find yourself in social situations where you are likely to eat foods with high lectin content.

    To be honest I use the shield only when I'm not controlling what I prepare to eat. I follow the diet quite strictly because if I stray I pay. While traveling the Lectin Shield is a godsend.

  • Life Changing Product

    My wife has suffered with ME from chronic fatigue for the last 25 years, we now live in Tuscany for half of the year as this does help with her condition.

    We started the Plant Paradox diet which also had a real beneficial effect, however, we were initially concerned that my wife, as a vegan, eating a lectin free diet in Tuscany would make life really difficult when visiting friends (no zucchini, aubergines and especially no gnocchi).

    The Lectin Blockers are the icing on the cake! Occasionally, she eats "dodgy" food where blockers totally override the negative effects, fantastic!

    Just out of interest, having read the book she discovered hemp tofu in Italy (don't think we can get it in the UK) and is now making her own!

    Thank you, Dr G for all your work.

  • Nothing happened!

    • Bakersfield, CA,
    • Jul 14, 2017
    • Verified Reviewer

    I had already been active in the Plant Paradox nutritional program and been taking the Vital Reds for better than a month before I read about and ordered Lectin Shield.

    I must say I was losing steam following the challenging Plant Paradox "diet" and cheated on it twice. Twice my gut punished me with days of relentless constipation and lassitude.

    Had I not enjoyed the serendipity to have read about Lectin Shield precisely when I did, I would have left the program. I had been invited to attend two days of fun and excellent cuisine at the coast, and it was on the following weekend.

    Not going was not an option. So I ordered one bottle of Lectin Shield and RSVP'd the invitation. One week later I was at my friend's home, with my mysterious bottle in my suitcase. We were running late for the play he had authored, so we had to wolf down a couple of grilled burgers before we left. I excused myself and popped a Lectin Shield in my mouth and returned to his patio.

    The cheeseburger was ambrosia to me. It was accompanied by wine and followed by desert before we left.

    The next morning, and the morning after I was delighted to discover that, well, nothing happened.! No grumbly gut. I was full of energy and enjoying myself insanely.

    A fluke? Hardly! The next time I used my Lectin Shield was several weeks later, at a going away party for my daughter. I was frying the tacos for the family, and I am proud of my tacos. It was no time for prudery. Besides I wanted one, two, no, three of them. But it wasn't before I downed a Lectin Shield. For good measure, I had another Lectin Shield afterward. The tacos were greasy-good!

    I'm still on the Plant Paradox program. How could a nutritional program like Dr. Gundry's not be good for my gut when the warning for my occasional departure from it can be so harsh? Unless, that is, one has his/her bottle of Lectin Shield at the ready for that rare cheat day when he's/she's gonna be Lectin-ly naughty?

    It's gonna happen, so why not prepare for it? That's why I'll always have my bottle of Lectin Shield in my cupboard or suitcase.

    I no longer have stomach cramps or excess gas and enjoy most of the food I have always enjoyed. As an aside, I have stayed pretty rigorously with the Plant Paradox eating plan and have enjoyed a significant reduction in weight.

  • Nice product

    Seems to be working, thanks. I enjoy the product, and I hope to make even more progress in my weight loss. I can't wait to get back into shape and get the body I always wanted. I think the lectin diet will surpass the carb and gluten diet. I tried both the carb and gluten free diet, but they don't deliver results like the lectin diet. I would definitely recommend this to friends and family.

  • A life savor!

    • Big Bear Lake, CA,
    • Jul 10, 2017
    • Verified Reviewer

    As far as I can remember, I've had awful stomach upsets. Since I have discovered my lectin sensitivity, (thanks to Dr. Gundry!), avoiding lectins has completely illuminated my stomach issues. However, life in America doesn't make it easy to avoid high lectin foods, so I carry the Lectin Sheild with me and take one if I'm eating out or happen to indulge in something that I know will pay for later. Lectin Shield really does protect against my reactions to the foods I'm sensitive too. It's not a license to eat anything I want, but I am so happy I have it when I need it. It really does work. Thank you Dr. Gundry!

    I go out to eat a lot with my wife who hasn't as of yet embraced my new way of eating. I use Lectin Shield when I need protection from possible lectin foods, usually sauces and dressings. I don't have an overt sensitivity to lectin, but I do want to protect my gut.
