About Lectin Shield

By HighYa Staff

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.

    My goal is to be as lectin-free as possible, so both my diet and Dr. Gundry's supplements are assisting me in that goal and better gut health. The Lectin Shield gives me some assurance that I'm riding my body of lectins as much as possible. Interestingly, if I've made one of Dr. Gundry's recipes and happen to forget my Lectin Shield, I realize "I'm safe!" FYI, I rarely forget to take my Lectin Shield!

    Good but results still not fully in

    • Alabama,

    My experience with Lectin Shield thus far is it allows me to eat more foods without fear of reactions. I have lost just a tiny bit of weight, but have definitely lost inches! Not sure why, but I have. I am not trying super-hard right now to lose weight, and feel fairly sure if I did, I would lose.

    My big question to Dr. Gundy is, do you have any indication that someone who has been diagnosed with Celiac could potentially be able to eat certain wheat products again with this?

    As mentioned today is only my second day but I found Primal Plants a bit unusual in taste, but I can just add to it Total Restore. I hope it works because of my age, 80 in six weeks. Also, I would like information on type two diabetes, which I have, but I can certainly send a further update after a further three weeks of use of these products.

    Once again many thanks.

    Two of us have been taking the two capsules twice a day for about two months and have noticed some definite improvement in our ability to enjoy certain foods that were problematic.

    One of us has dealt with IBS for many years and has seen that it is improving since adding this regime and would like to continue

    Both of us find the Lectin Shield beneficial.

    I can tell an almost immediate result after taking my Lectin Shield.

    I am less bloated and suspicious that I am slimming down.

    Today I even told my husband about the product when we were eating lunch together and he was trying to pick the tomato seeds out of the tomato to avoid lectin. He is trying the product and I believe he will be pleasantly surprised.

    I haven’t used the product long but I am convinced I don’t want to be out eating and not have it available. I’m looking forward to even better results as I continue using Lectin Shield.

    Thank you Dr. Gundry.

    I have been taking Lectin Shield for one week along with pre and probiotics and Vital Reds from Dr. Gundry. I also began a lower calorie paleo diet at the same time. My digestive tract is much, much happier and I have lost 6+ pounds in one week.

    My only complaint is the cost. I am retired and on a fixed income, even with purchasing more of each item to get a discount, I don't know if I can continue with these supplements.

    I noticed a change in my digestive tract immediately! I have GERD and I have diabetes 2...so you know that I am serious concerning my wellness. After viewing Dr. Grundy's video, I was compelled to act on the knowledge I had just received. I heard of the "leaky gut." For sure I have all the signs. Now that I have been following the Mediterranean diet, added walking, and the Lectin Shield, my bloating is slowly going down, lost inches off my waistline, I believe the bigger picture will be validated when I have my next lab work. My labs after two weeks of taking Lectin Shield were unbelievable. I can send them to the doctor if requested. I feel confident again as if I took back the will to fight for my health. Thank you Dr. Gundry.
