About The Brand

Dr. Steven Gundry MD is one of the leading heart surgeons in the United States of America. He was the founder and the director of one of the clinics in the US namely, “The International Heart & Lung Institute for Restorative Medicine”. Dr. Steven shifted his career into wellness medicines and became one of the best-selling authors in the New York Times with his book about the plant paradox food list: “The Plant Paradox: The Hidden Dangers in Healthy’ Foods That Cause Disease and Weight Gain”.

Dr. Steven was the one to propose Leaky Gut Syndrome, which many doctors do not agree that it is a real disease. His theory and belief made him a very controversial health expert all throughout the world.

He had produced many products such as Polyphenol-Rich Olive Oil and Bio Complete 3. He claims that his products provide people a healthier body. Specifically, people using his products may get a healthy gut lining and digestive system. However, in today’s review, we are going to examine Gundry’s Lectin Shield.

Is it effective? How does science support his idea of lectin blocking and lectin-free diet? Find the answers in our lectin shield review.

What Is Lectin Shield?

Lectin Shield is a product formulated by Dr. Gundry. According to him, the goal of Lectin Shield is to block, filter, or illuminate the harmful effects of proteins called lectin, which is often found in plants, fruits, or vegetables making them harder to digest.

He further describes the product as good intestinal support, and it is best to include it in people’s diet. Thus, he suggested that people should take it twice a day with two capsules in each intake, having four capsules a day.

What Can Lectin Shield do?

Gundry believes that through a lectin-free diet, people will experience little to no constipation and other digestive-related concerns. Thus, he created his Lectin Shield.

According to his website, lectin shields support intestinal health, reduces the chance of experiencing bloating, and lessens your cravings for lectin foods. Moreover, the nine ingredients of lectin shields have antioxidant and anti-fatigue properties that help your body to experience a more calming effect.

Gundry MD Lectin Shield Ingredients Reviews – Does it really work?

Gundry MD Lectin Shield contains 300m of N Acetyl D-Glucosamine (NAG), 200mg of Bladderwrack, 100mg of D-Mannose, Okra Fruit, Mucin, and Sodium Alginate (Alginic acid), 50mg of Vegetable Peptase, Methylsulfonylmethane (MSM), and Larch arabinogalactan. Most of these ingredients contain Lectin blockers, while some have additional benefits like pain loss, weight loss, and decrease of appetite.

Lectin Shield

N Acetyl D-Glucosamine

N Acetyl D-Glucosamine[1] is an amino derivative that tends to reduce unsafe wheat lectins. In other words, it has lectin blocker properties, helping the reduction of an array of digestive problems as well as joint issues. 

This is also used for drug medication for coronary illnesses and dietary enhancements — like Gundry Lectin Shield. However, despite its benefits, it has also a couple of side effects.

If taken with a higher dosage than your body can carry, you may experience looseness of the bowels, stomach upset, and indigestion. Moreover, it is not recommended for people who have a high sensitivity to shellfish taking such an amount of N Acetyl D-Glucosamine. If they do, they may experience rashes, windedness, and wheezing.

Bladderwrack

Bladderwrack is a type of seaweed that is used as one of the ingredients of supplements related to diet, especially for weight loss. It also ties with risky, fiery lectins. As a result, it filters lectins that pass to your gut. 

Bladderwrack is capable of creating an anti-inflammatory effect by doing faster digestive processes. Afterward, your body will allow these harmful lectins to flash out through our excretory system.

D-Mannose

D-mannose[2] is a type of natural sugar that binds two sugars like N-Acetyl-D-Glucosamine allowing body proteins to react with some bacteria. It has an antioxidant effect on the body, including explicit harmful lectins.

Research suggests that it contributes to the functions of the liver, as well as our blood’s health. Taking a small amount of it will not harm your body. However, if taken more than the standards may impair your kidney 

In the case of Gundry’s Lectin shield, only a small percentage of D-mannose is present. Thus, having such risk is lower than those who self-medicate.

Okra Fruit

Okra Fruit, as the name suggests, is a fruit. It contains a substantial amount of raw polysaccharides (RPS). This helps reduce, illuminate, or prevent harmful effects of lectins.

It also contains polyphenol, a chemical with anti-oxidative properties. Moreover, it helps you to have a good amount of energy. Thus, you will be less likely to experience great fatigue.

In addition to those benefits, Okra Fruit furthermore contains potassium, vitamin B and C, folic acid, calcium, and natural dietary fibers. This certainly complements the health benefits of the Gundry Lectin Shield.

You must take precautions though, especially if you have certain medical conditions as it may interfere with your other medications. For example, oxalates, one of the contents in Okra may bind with gall and/or kidney stones, causing gall and/or kidney to further deteriorate.

Furthermore, taking a very high amount of Okra Fruit may cause gas, cramping, bloating, and diarrhea. It is always better to consult a doctor first, especially if you have a chronic medical condition and are taking drug medication.

Mucin

Mucin is a type of protein taken from epithelial tissue of some animals, most especially from snails. It is known best for its contribution in the creation of a slippery protective barrier within our digestive system.

Mucin also contains sialic acid[3], making it capable of binding to multiple lectin-based foods’ sources easier. Such foods include wheat and some types of fruit berries. Mucin may also provide dry skin prevention with its anti-aging benefits through its capability of producing collagen.

Even though Dr. Gundry does not focus on skin health, there is a greater possibility of acquiring healthier skin because of this ingredient. However, its most primary goal is to block Lectins, especially the harmful ones.

Mucin does not have harmful effects as long as it is taken without overdoing it. High amounts of Mucin may cause eye irritation and some symptoms of dry eye. People having an allergy to the said compound might also experience these side effects.

Sodium Alginate

There is no known negative side effect for Sodium alginate. Its other positive effects include controlling levels of cholesterol, and/or hypertension (High Blood Pressure). Of all the ingredients found in Lectin Shield, this is probably the safest.

Vegetable Peptase

Vegetable peptase is a kind of protease enzyme aiding digestion and works well with certain proteins. It can also breakdown other harmful proteins that may be present inside our digestive system, keeping our digestive tract healthy. In addition to that, it also releases pain, reduces inflammation, and may prevent infections. 

When you take a food supplement containing Vegetable peptase, experts suggest consuming it two hours before meal. If not, your stomach should be empty. It is somehow contradicting how DR. Steven Gundry suggests — taking Lectin Shield with your meals. On the other hand, Vegetable peptase dosage needed to be effective should be high, especially for food supplements –complimentary to Gundry’s suggestion — 2 capsules twice a day.

Methylsulfonylmethane (MSM)

MSM or Methylsulfonylmethane is a great compliment for N-Acetyl D Glucosamine. It is considered a powerful agent for joint pain or discomfort. Specifically, it reduces inflammation.

Methylsulfonylmethane should not be taken in a higher dosage unless you can afford to experience its mild side effects. It includes diarrhea or other digestive discomfort.

It is also not recommended for people who are breastfeeding their child as well as those who are pregnant. In addition, do not take any supplement like Gundry Lectin Shield if you are allergic to sulfa, unless your doctor allows you of doing so.

Larch Arabinogalactans

Larch Arabinogalactans are starch-like chemicals found in many plants. They have the capability to increase your level of butyrate. The butyrate is responsible for nourishing your gut lining, ensuring that your body will be able to defend you from harmful substances such as lectins.

Arabinogalactans also help in treating common colds and flu and are used in many dietary fiber supplements. Furthermore, it boosts the immune system and is able to lower your cholesterol level.

Arabinogalactans are generally safe to use. However, it may cause side effects like bloating and flatulence (intestinal gas). Furthermore, it is best to avoid Arabinogalactans if you have an autoimmune disease. This will aggravate the symptoms.

Health Benefits of Lectin Shield 

According to many researchers conducted recently, not all lectins are harmful. However, there are some types of lectins that truly damage the human gut lining.

Dr. Gundry believes that these lectins are the cause of some diseases. He says a lectin-free diet improves our overall health. From digestion, immune system, energy to common colds, lectin blockers can certainly help.

In contrast with Gundry, even other doctors working at his founded clinic “The International Heart & Lung Institute”, contradicted most of his theory. According to doctors’ reviews, there is not enough supporting evidence that his lectin-free diet really helps.

  • Improve digestive health
  • Supports immune system
  • Improves bowel movement

Is Lectin shield safe?

According to Dr. Gundry, “Gundry MD Lectin Shield was created for optimal all-natural purity.” He further emphasized that he uses a high graded and an easy to close amber glass to maintain the potency and purity of all the ingredients.

When it comes to product consumption, we recommend you to consult your doctor first. This especially applies to people with existing medical conditions.

For instance, some of its ingredients may cause an allergic reaction. It may also worsen symptoms of autoimmune diseases.

If you decide to use Gundry MD products like Gundry MD Lectin Shield, expect for certain side effects. In most cases, users are able to tolerate these side effects. Nevertheless, the product is generally safe to use.

How to take lectin shield?

Dr. Steven suggests taking lectin shield capsules two times a day. Each intake should consist of two capsules. His best recommendation is taking it during your large meals.

He said that the product’s effectivity (how your body reacts to it) depends on how consistent you are in terms of using the product.

He also acknowledges the uniqueness of every individual. Thus, he stated in his website that there is no absolute time frame on how long it takes to feel its effect. In addition, there is no absolute percentage of a guarantee that your body will positively react to it.

According to the research, you must consult your physician or doctor if you are allergic to seaweeds or shellfish before taking lectin shield. The same advice goes to those who are 7 years old or below.

You must also take extra precaution if you are pregnant or having an existing medication. Always remember that supplements are not replacements for medicines. It will never be intended to treat or cure any kind of illnesses.

Potential Side Effects

Looking upon the ingredients, they are generally safe. However, there is not enough research on this type of diet.

Unsatisfied customers only complain that the product is not working the way they expected, or they only experience its side effects. Here are some of their statements:

“In just a couple days of using this product, I have developed unrelenting heartburn. It was so bad. I was barely able to get any sleep last night. There is only one other Lectin blocking product I’ve tried that caused heartburn, and that one had Pepsin in it, which was the culprit. This one has peptase, and is evidently no better tolerated than Pepsin.”

The bottom line

Many of us know that some fruits and vegetables we eat, though known as healthy foods, still contain harmful lectins. Many doctors do not advocate for lectin blocking products because you might also be losing the benefits safe lectins offer.

However, Dr. Steven Gundry is proposing that all these lectins are harmful to the human body. Regardless of whether we believe his statement or not, let us remember not to do self-medication. In addition, we must keep in mind that as you take any dietary products, you may also get to experience certain side effects.

Lastly, you can still adjust your diet if you do not want to expose yourself to Lectin blocker products. All you have to do is avoid foods with lectins.

You have to make an extra effort to achieve the result. However, you will be less likely to experience negative effects.
