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?

  • 1 Bottle: $39.95

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.

  • Lectin Shield

    I am still in the trial stage on one bottle purchased. Seems to be doing its job if I remember to take it before eating. I was wondering if the batch was bad until I read one of the main ingredients is N Acetyl D-Glucosamine from crab and shrimp. So far I have loved all the products I've purchased from GundryMD.com, keep up the good work Dr. Gundry.

    I started the Lectin Shield tablets a month ago. The most noticeable difference in the supplement is my lack of aches and pains. After I turned 40, I realized that each morning that I woke, something hurt. It could be my back, neck, shoulder, but there was always a nagging pain. I have never been over weight and always been fit, so weight really wasn't an issue. I had put on a few pounds but nothing that should be stressing my joints. I have found that the Lectin Shield has kept my exercise injuries and aches and pains at a minimum.

    I only use it when I know I'm going to be in a situation that requires the Lectin Shield (family get together, friends out for a bite and so on).

    So far it is working very good, and I'm so glad I bought it. I wouldn't be without it.

    I feel awesome!

  • Great thing to have available for us

    The Lectin Shield for me is a way to be able to sometimes deviate from the way we eat when necessity calls. After three years of completely avoiding all grains when traveling with no other choice for me, I was able to eat pizza without any consequences with the help of the Lectin Shield. Now I'll also be able to go to dinner with friends without being the "difficult" one to cater for. It provides us with another way of dealing with the other challenges arising from our choice of this way of life.

  • Great product

    I have a lot of digestive problems, I have terrible trapped gas, and it's hard for me to follow Dr. Gundry's diet by keeping the lectin out of the food I eat. These tablets give me a peace of mind and help with my digestive problems. I recommend this product with all the confidence that this product works.

  • Traveling and parties

    I love Lectin Shield. It helps make traveling possible. Eating in restaurants prior to Lectin Shield was nearly impossible. Sometimes the ONLY item I could order was steamed broccoli! I have a great sensitivity to bread and potatoes. Nearly every item on restaurant menus has one or both in them. Also, I have much difficulty when attending parties. I love to be able to partake in birthday celebrations with my grandchildren. I don't have to be "weird" grandma who doesn't eat anymore.

    I hope that soon my family will get on board onto a healthy lifestyle. I want to be a good role model for them and hope that my great health eventually turns them around.

    Lectin blocker is the icing on the cake of other excellent Gundry products

    • Regina, Saskatchewan, Canada,
    • Jul 26, 2017
    • Verified Reviewer

    Lectin blocker seems to reduce pain and inflammation for my fibromyalgia and promotes weight loss along Vital Reds in a very significant way.

    I was trapped in obesity and yo-yo dieting. Always hungry, fighting cravings, and doing well on diets until I just couldn't keep going and would give up. With Gundry products and cutting out sugar to a large extent and eating good proteins regularly, I have lost a lot of weight with out the torture! I don't feel hungry all the time, hungry right after a meal or obsessed with cravings so I feel free for the first time from the control of food. I don't live to eat anymore, but I still enjoy eating. My husband and I keep losing inches too. It has been fun and surprising.

    Lectin blocker seems to make things even better because many foods caused my inflammation and fibromyalgia to flare so badly or my fatigue to hit so hard, but with Lectin Shield it seems to reduce the impact of certain foods and allows me to enjoy a bigger variety of foods without the painful consequences. It doesn't mean perfection but it does offer a definite amount of relief, and I am more than grateful. Thank you Dr. Gundry.

  • Can't assess

    I say "good" because I have no reason to believe it's bad, but I don't know what to look for. I've dropped lectins from my diet and take it only when I eat something that's questionable, or eat out and learn ingredients like green and red peppers, let's say, were used in cooking. But I have no way of measuring the effectiveness of Lectin Shield.

  • How I use Lectin Shield!

    Currently, my family and I are working on eliminating all lectins from our diet. Like with anything, "change" can be a difficult thing. We have incorporated using the Lectin Shield when we dine out.

    This way if my daughter wants a little pasta, or my hubby has a few chopped tomatoes in his salad, we are covered. I am totally on board with Dr. Gundry's Primal Plants, Vital Reds and now Heart Defense, but for those times when the old "change" monster raises its pesky head, we have our Lectin Shield to help!
