The Complete Guide to Gundry MD Lectin Shield: Ingredients, Benefits and How to Use

What Is Gundry MD Lectin Shield?

Gundry MD Lectin Shield is a dietary supplement designed to help protect against potentially harmful lectins commonly found in plants. Lectin Shield contains a blend of compounds that work together to help block lectins from disrupting the digestive system.

Lectin Shield is a great option for those looking to support their gut health.

What Are The Ingredients In Gundry MD Lectin Shield?

Gundry MD Lectin Shield contains nine powerful active ingredients:

  1. N Acetyl D-Glucosamine
  2. Bladderwrack
  3. D-Mannose
  4. Okra (fruit) Extract
  5. Mucin
  6. Sodium Alginate
  7. Vegetable Peptase
  8. Methylsulfonylmethane
  9. Larch Arabinogalactans

Each of these ingredients has unique properties that can positively impact the body in different ways.

Potential Benefits Of Using Gundry MD Lectin Shield

Gundry MD Lectin Shield works by targeting the activity of dangerous lectin proteins and other harmful substances.

Here are some of the specific potential benefits of each of the potent ingredients found in Gundry MD Lectin Shield:

  1. N Acetyl D-Glucosamine

    N Acetyl D-Glucosamine binds to harmful wheat lectins which have been associated with joint issues. This lectin blocker is a popular ingredient in many joint health supplements.1,2

  2. Bladderwrack

    Bladderwrack is a powerful variety of seaweed that’s been shown in studies to bind to lectins.3

  3. D-Mannose

    D-Mannose is a potent natural compound that’s able to bind to specific lectins in legumes (a lectin-rich food).4

  4. Okra (fruit) Extract

    Okra is often cited as a strong “lectin blocker” because it’s a source of raw polysaccharide (RPS), a powerful compound that binds to multiple lectins. Okra is also a rich source of polyphenols and has shown powerful antioxidant and anti-fatigue properties.5,6

  5. Mucin

    Sialic acid found in mucin binds to lectin-containing foods, including those found in wheat and several types of berries. Mucin also helps to form a “slippery” protective barrier inside the digestive tract.7,8*†

  6. Sodium Alginate

    Sodium alginate acts as a “fecal bulking agent,” which can help make bathroom visits more comfortable.9*†

  7. Vegetable Peptidase

    Lectins inhibit peptidase, a crucial enzyme that your body uses to break down proteins in food. Vegetable peptidase can assist in protein digestion and help counteract the digestive effects of lectins.10*†

  8. Methylsulfonylmethane (MSM)

    Foods containing lectins have been tied to joint discomfort, and MSM has been shown to be a powerful means for helping reduce joint discomfort — especially when used in combination with N-Acetyl D Glucosamine.11,12*†

  9. Larch Arabinogalactans

    Arabinogalactan has been shown to support butyrate production in gut bacteria. Butyrate nourishes your gut lining, which is your first line of defense against destructive lectins.13,14

How To Use Gundry MD Lectin Shield

Step 1: Take The Correct Dose Of Lectin Shield

Lectin Shield comes in the form of easy-to-swallow capsules.

It’s recommended that you take two capsules of Lectin Shield, twice daily. That means that you’ll be taking four capsules in total each day.

For best results, take Lectin Shield with your two largest meals of the day, and remember that consistency is absolutely key to experience the best results.

Always take the supplement with a full glass of water. This will help the supplement to dissolve and be better absorbed by the body.

Step 2: Raise Your Shield Level

If you want to support your intestinal health and help shield yourself from harmful lectins, you can “raise your shield level” when using Gundry MD Lectin Shield.

Here’s how:

  1. Take the recommended dosage as directed on the label: at least four capsules per day, two per sitting, with your two largest daily meals.

By following these steps, you can help “raise your shield level” of defense against lectins and help support your overall health.*†

I’ve been taking Lectin Shield for over two weeks now and have noticed improved gastrointestinal function. I have a more stable energy level... I am hopeful that this trend will continue and that I will experience greater improvement over time. I have experienced no adverse effects.

John A. Skorupa, on 05-15-2022

The product is easy to take. I haven't noticed any physiological changes, though.

Lectin Shield

Good product so far. No side effects that are negative.

Walter Tizura, on 05-08-2022

It works for me. Since I have started taking the Lectin Shield the constant itching of my torso has lessened considerably or stopped completely on certain days.

Marcia Kral, on 05-08-2022
Immediate Results!

I eat on an average of 4-6 fresh fruits and vegetables per day. Before taking lectin shield, my hands were sore and stiff. Making a fist was impossible. Three days after lectin shield, the soreness and stiffness began to subside. Within a week, all function returned to my hands. I can even eat nightshades with no consequences. I’m sold on this product and will never stop taking it.
