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.

In order to request a refund, you’ll need to call Gundry MD customer service at (800) 852-0477.

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.

    Don't buy or trust this company!

    • Indianapolis, IN,
    • Jan 6, 2018
    • Verified Reviewer

    After a high-pressure internet "educational" video, I purchased THREE bottles of this product.

    I got it home and realized that I am allergic to the ingredients in the product! Do you think that the company will stand behind their product video and admit that they failed to mention not to buy if you are allergic to SHELLFISH?

    I can now mail it back at MY EXPENSE. I question the reputation of this allegedly "renowned" physician.

    Bottom Line: No, I would not recommend this to a friend

    System glitch

    I logged in searching for Lectin Shield, looking for the best deal. It was a single bottle for $79.95, but I clicked the button at the top for deals for new customers, chose the 6-bottle price at what appeared to be $37.45 each. I had just listened to the video and wanted to try it. I went through the process and made the purchase.

    I had to tell the system "NO" to 4-5 additional products, including Vital Reds as I already take a 'Feds' product I like. I discovered at the end of the order that I actually purchased Vital Reds. Had I not scrolled down and looked at the receipt, I would have received Vital Reds in a few days, and probably would have had to pay to ship them back.

    I called immediately and they canceled the order. I decided not to try the product after all!

    Bottom Line: No, I would not recommend this to a friend

    Beware, unless you want to lose your money.

    I am not commenting on the product, I don't know if it works, but about their billing practices. I bought a 6 months supply by Visa. I was shocked that they sent and used my Visa details to fund another order also of 12 months supply. I immediately contacted them, but they won't refund my money as they say it has been shipped despite the fact I placed the order at 1 am Eastern Standard Time. Do US workers even work then? Surely there must be laws in the US to protect consumers. They exist in our country.

    So beware, don't trust this company.

    Refund

    I listened to the entire video about Lectin Shield and felt convinced that this product could give me digestive strength, which I have always felt I struggled with. When I ordered Lectin Shield, I wasn't feeling sick, but then I started feeling bad pain in my stomach just before receiving my bottle of the Lectin Shield. I started taking it in the hopes that it will aide in me feeling better. I went to see my doctor for the pain, it has been so bad, and he wants to do tests and procedures to find what is going on and told me to stop taking Lectin Shield. He wasn't saying that Lectin Shield caused my problem and neither am I, but at this time, something is wrong and I need to stop all meds, etc.

    When I am diagnosed and feeling better, I will consider ordering again, if this refund goes smoothly, which so far it hasn't. I have written twice asking for instructions to send my bottle back and receive my refund and have gotten NO response, which really concerns me for any future order with this company! It shouldn't be this difficult!

    I bought a six month supply by using my Visa, as I thought the 90-day return would be ok if the product were a scam, but I was so shocked to see after checkout they used my Visa details to fund another order of 12 months supply! I immediately contacted them, but they won't refund my money as they say it had been shipped, despite the fact I placed the order at 1:00 am Eastern Standard Time. I contacted them as soon as I saw the additional amount on the receipt!

    I pointed this out to them and they took numerous days to reply to further messages that I sent expressing serious concerns, about what they did. And I mentioned a couple of other issues that made the transaction appear completely dodgy, as the information they said in emails contradicted information in the lengthy video. Each email avoided my request to cancel the order and gave pre-rehearsed marketing type answers. This is ambush marketing and theft.

    Stomach pain

    • Florida,

    • Verified Reviewer

    I have been taking Lectin Shield for a couple of weeks. I primarily decided to take it to help with digestive issues. One of my primary concerns is bloating and some irregularity. My experience has been that my stomach hurts and is bloated each time I take a dose. One benefit is that my regularity has improved. However, I think I'm going to stop taking it. I'm sitting here with a heating pad on my stomach because I'm experiencing so much discomfort. It's not worth it to me.

      Hi Kris, my name is Aria with Gundry MD. I’m very sorry to hear that this was your experience with Lectin Shield. I’m happy to hear that your regularity has improved, but abdominal pain is not a typical side effect of taking Lectin Shield. Please stop taking the product until you consult your physician to ensure that it is right for you. If you are unable to take Lectin Shield or would like to return your product, please email me at aria@gundrymd.com, and I will be more than happy to issue you a full refund just for giving the product a try.

    Use it when out

    I don't use this product regularly. Instead, I use when I am invited out to a meal or traveling, as protection against unexpected lectins. Sometimes it is just not possible to avoid all lectins when you are traveling or invited out to a meal.

      Hi Mark! Thank you so much for taking the time to leave us a review. You are so right! In an ideal world, we would be able to avoid all lectins all of the time but we do understand that this may not be possible for everybody. Although we do strongly encourage it, and that is the exact reason Lectin Shield was created. We are so glad to hear that you are using it when you can to avoid lectins as much as possible!

    Effectively ripped

    • Jul 25, 2018
    • Verified Reviewer

    If you want to get effectively ripped in less than an hour all it takes is to listen to the Lectin Shield video. Dr. Gundry has a clever way of pushing you into a nine bottle purchase without even requesting one. Beware of such hackers! I heard the whole video to learn in the end they just want to push products and volume.

    I decided a 3-bottle trial but realized inadvertly they sold me into 9 bottles. I called immediately to cancel the order but they said the order had been shipped! How efficient! I called my bank to stop the order.

    In less than I week I had the order in my house and a charge of $168.00. I tried 2 pills and got diarrhea immediately. I do not suffer constipation but bought the story of preventing glue in my bloodstream. I will follow his advise and try for 30 days and decide to return the other 8 or continue as another guinea pig and confirm if I was effectively ripped off.

    Why the supplement if you follow The Plant Paradox diet? The whole online order process reeks of snake oil with offer after offer presented to you before placing the final original order. I am trying one bottle and carefully monitoring digestive, energy, weight loss results. I'm currently following a whole food plant based diet and going to incorporate a few diet changes based on The Plant Paradox book. Thirty days should show, according to the program.

    I received my bottle of Lectin Shield today and understood the cost for shipping and handling to be minimal (which turned out to be $9.95, not bad). The Canadian government converted the original cost to Canadian money and charged me PST and GST on the above, which was over $58.15. I had to pay the taxes at the post office before I could get these goods.

    Note: on the bottle, it says to just take two tablets a day just before your biggest meal. It doesn't say to take two twice a day like in the above article.

    I am hoping for small miracles with this and will keep in touch.

      Hello Sandy, thank you for reaching out about your experience with Lectin Shield. I sincerely apologize for any extra fees you were charged by customs. Unfortunately, only 10% of international products are flagged when they go through customs and we have absolutely no control over what your country of residence chooses to charge you.

      In addition, the frequency in which you take the pills varies for each customer. We recommend starting with two per day, which can be increased on an as needed basis. I would love to hear about your continued progress with Lectin Shield. Please feel free to email me with any updates at aria@gundrymd.com. Thank you Sandy.
