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: $49.95
  • 3 Bottles: $131.85
  • 6 Bottles: $239.70

All U.S. orders come with free shipping, while all Gundry MD supplements (more about this next) come with a 90-day money back guarantee, less S&H charges.

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.

    Wow, I'm 62, look like 52 and feel like I'm 30! Dr. Gundry's polyphenol-rich, lectin-free diet and GundryMD dietary supplements like Lectin Shield are renovating my body and making me look and feel younger. Lectin Shield is an easy and convenient way to protect your body from reacting to the damaging effects of lectins that slip past a mainly lectin free diet. Once I was an obese middle-aged 104kg man who suffered from fatigue and thought my life was over. I had never heard of a lectin or the role they play in nature and the food chain. I made many positive changes to my diet but couldn't bust through the 88 kg mark. Thanks to Dr. Gundry for sharing his knowledge and research into the causes and effects of foods that make us overweight and unhealthy, and my thirst for knowledge to improve my health, I reckon I found the secret to unlocking a healthier life. I tuned in to Dr. Gundry's blog, videos, and books to educate myself about what can and does overcome the damaging effects of eating the typical western diet. For about 30 years I also suffered from some itchy skin rashes in my crotch and butt cheek. I also had intermittent outbreaks of pain in my shoulder and hands. After reading Dr. Gundry's work on lectins and polyphenols, I changed to a mainly lectin free, polyphenol-rich diet. I use Lectin Shield as a daily defense against the rash and pain returning. It works for me. Try it. It might work for you too.

    Lectin Sheild seems to reduce the amount of nausea I sometimes feel after I eat breakfast. Because it's not eliminating it, I've added Total Restore every morning, which is making more of a difference. It's hard to know what GundryMD product to use as they all seem to claim the same benefits - better digestion, better skin, weight loss, etc. When the Lectin Shield runs out I won't re-order it, but simply continue with the Total Restore, hoping it will address the problem more directly, which I believe to be leaky gut. Practically speaking, I can't afford to continue taking both products.

  • It is hard to pinpoint results

    • Peoria, AZ,
    • Jan 17, 2019
    • Verified Reviewer

    I make a point of taking Shield if I know I will be eating something with lectins. That doesn’t occur often, and I’m never sure if it works. As a rule, I don’t have immediate reactions to less than optimum food choices. I keep a bottle at work and one at home. I also keep a bottle in the car for when I am eating out with friends. Generally, I eat correctly, and I think that has the biggest effect. So I am using Shield as a backup.

    I would only recommend Shield to someone who is committed to this way of eating. It is expensive and most of my friends would be skeptical and unable to spend that much money on something I can’t guarantee is having a measurable effect.

  • Looking forward

    • Orchard Park, NY,

    Although the results are yet not on a grand scale, Lectin Shield is the first product which my wife and I nonetheless have experienced to be directly what its claims are. That's quite a collection of products to be at the top of.

    Having introduced and coupled the Total Restore product to our diet and lifestyle just before the holiday season of 2018, we were impressed to see positive changes combined in the direction of their mutual claims over and above the overwhelm of the holiday season diet. We are now looking forward to even greater results with the New Year and a more normalized diet.

    With select and shield, my wife and I each have noticed an obvious reduction of puffiness around our face and stomach area and hips. This was clearly a defined result of the Lectin Shield itself.

    With the addition of Total Restore, a definite improvement of our sleep quality, energy, joint pain, and skin issues have been each clearly observed since the beginning of December, roughly six weeks ago now.

    We are looking forward to more intense gains on a larger scale in the weeks and months to come. With Santa having left us both The Plant Paradox book and cookbook for Christmas, we are excited for achieving the results we've hoped of for decades in addition to our very active lifestyle.

    From what I’ve experienced using Lectin Shield for a couple of months is that it seems to really work. When I know I have to eat lectins, i.e., fam gathering, co-party, friend’s house, etc., I take the Lectin Shield. I don’t suffer afterward like I used to. I really like having these in my arsenal as an option to avoiding the damage lectins do to our body.

    I use it mainly when I go out to eat since I’m not sure if the vegetables are organic or the fish is wild caught. It has helped me to maintain my weight loss.

  • It has greatly impacted my stomach discomfort

    • Redwood City, CA,
    • Jan 13, 2019
    • Verified Reviewer

    I have been a single dad for over 10 years. I learned to cook at an early age and have been cooking daily since then. I have custody of my children every other week, so I am responsible for them. As such, I have prepared meals for them and myself believing I was cooking healthy foods to keep us all healthy. I did not know or realize the problems that lectin can cause in your diet. I also did not realize how many different foods contain lectin or the amounts in the food I prepared. Until I began to read the information put out by Dr. Gundry and also follow up research from different sources, I prepared a number of dishes that were Lectin rich. I had begun to experience bloating, acid reflux and discomfort a few years back, without realizing what it was. My doctor could not tell me why I had the acid reflux, discomfort or bloating.

    By happenstance, I found Dr. Gundry's page that had a video explaining the leaky gut syndrome, and I have never looked back. I have ordered a number of his products and Lectin Shield was one of them. Since I have started Lectin Shield, I have found that I have not experienced the acid reflux, bloating or discomfort I have dealt with for a number of years. I have and will continue to pass on his information to family and friends and hope they read up on his products and take the same chance I did. I believe they will achieve the same benefits I have.

    Lectin Shield has been a great product for me. Before I started taking Dr. Gundry products, my stomach never felt settled. In fact, it made me think if I just ate more it would quiet down. It turns out that wasn't the problem.

    Now my body feels more "balanced." I even sent my sister-in-law some of the product for Christmas as she has struggled for years with leaky gut. Here was the reply I got just this morning:

    "These products have made a believer out of me. I'm surprised and impressed by how much better my stomach feels after a short period of time. Also, I've been on antibiotics and have had absolutely no stomach irritation, whatsoever, which is a first for me."

    See two good reviews in one!
