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

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.

    I tried everything to get my stomach back on track. Then I discovered Dr. Gundry's Lectin Shield. The first couple of days I did not notice any real change, but by the end of the first week, I saw a complete change. I have now been on the Lectin Shield for four months and am super happy with my results. No bloating, gas or diarrhea after eating certain vegetables. My wife is now taking the Lectin Shield as well.

    I recommended this product to my family and friends. Well worth the cost.

    Problem solved

    • Ocala, FL,
    • Nov 13, 2018
    • Verified Reviewer

    I've been following the diet program from Dr. Gundry's The Plant Paradox for a few months now, and am within 5 pounds of my weight loss goal. My other goal, to be healthy, is also right on target. However, I confess to an occasional dip into the "forbidden" pool of comfort foods, only to have my stomach react almost immediately. Apparently, the "bad gut bugs" that used to thrive there, looking for lectins, are gone. The "good bugs" don't know what to do with foods that shouldn't be there, and it's very uncomfortable. Clearly, my body is telling me I'm on the right program, but I'm still going to cheat sometimes. I now take Lectin Shield with meals that veer a little, or sometimes a lot, from the wiser path, and I no longer suffer afterward. My problem has been solved. Thank you so much for coming up with the answer.

    Lectin Shield

    • Sandy, UT,
    • Nov 12, 2018
    • Verified Reviewer

    I purchased the Lectin Shield for the benefits of helping reduce the inflammation of my joints. The surprising benefit I have noticed is that if taken just before a meal or with a meal, it is about 90% effective in eliminating the passage of gas. It seems to really help in digestion. I usually take it at least twice a day and sometimes an additional midday dose. I have even started carrying a few in my purse to take if I have a meal away from home. I take Dr. Gundry's Prebiotic and an RX Probiotic. I have eaten a diet high in fiber and have for many years but still have embarrassing gassy episodes throughout the day. Lectin Shield has reduced this greatly. I hope it is doing as good for my joints as it is for my digestive track. Thanks, Dr. Gundry, for introducing me to this product and asking me to share my results. I hope my experience may be helpful to someone else.

    My life partner and I were in our 4th week of Phase II of The Plant Paradox Diet when we went on a trip to Mexico. We had to eat some things that we knew where not fitting with our diet plan. Lectin Shield kept us on track with no ill effects. We are home now and progressing with our diet plan and a new healthier life.

Since reading The Plant Paradox, using the yes/no list as a guide, and starting the products 6 weeks ago, including Lectin Shield, I haven’t had any pain in my knees, my heartburn has disappeared, I haven’t had a migraine, and I’m sleeping very well, and am not tired in the afternoon!

    Lectin Shield is my protection.

    • San Jose, CA,
    • Nov 9, 2018
    • Verified Reviewer

    I learned two years ago nightshades caused inflammation to my finger joints and other parts of my body, so by avoiding them I felt better. It was hard to do, since with almost every meal I would encounter something and sometimes I would just eat them instead of spending time picking it out of the dish. One summer a year ago I was able to avoid eating tomatoes and potatoes completely. I felt much better. However, I missed the nourishing aspects of the vegetables. As a result, I resumed eating tomatoes, potatoes, eggplant, etc. this summer. The of course inflammation set in. I tried prickly pair cactus juice, it helps some.

    Lectin Shield gave me the freedom to decide to shield myself from the inflammation properties of tomatoes, potatoes, eggplants, beans, lentils, etc. So now I take 1 or 2 capsules of Lectin Shield before I eat any vegetables I know that may cause me joint problems. It has made my joints happier. I still have symptoms but not as severe as in the past. I suppose if I took it daily as I did in the beginning, it would be best. You see, I figured when the symptoms reduced, I wouldn't have to take it regularly, only if I ate the offending foods, to "shield" myself from the lectins I ingest.

    I have been using Lectin Shield for two months and am very pleased with how I feel. I take two capsules before a meal high in lectins and find it helps with my allergic response to the toxins in lectins. It basically keeps me from having my usual allergic reactions to any foods high in lectins. I eat out a lot, so I find it nearly impossible to avoid the foods with lectins that I am able to avoid when eating at home. Thanks Dr. Gundry for a great product!
