Lectin Shield Review – Does Dr. Gundry’s Product Work?

Here’s our Gundry MD Lectin Shield review. In it, our team will be analyzing this product’s ingredients to see if it can block lectin absorption and support your gut health.

If you already didn’t know, lectins are proteins found in many plant foods. Many people get negative effects from eating lectins – such as reduced energy, bloating, intestinal cramps and high blood sugar.

Lectin Shield, as the name suggests, is there to make life easier for you.

Claimed benefits of Lectin Shield are:

  • Promotes regularity and pleasant bathroom visits
  • Helps reduce feelings of gas and bloating
  • Aids against out-of-control food cravings

Sounds promising! But does it really work? We analyze everything in depth below.

Formula Analysis

Here are the ingredients in Gundry MD Lectin Shield as shown on the label:

  • N-Acetyl D-Glucosamine (300mg)
  • Bladderwrack (200mg)
  • D-Mannose (100mg)
  • Okra Fruit (100mg)
  • Mucin (100mg)
  • Sodium Alginate (100mg)
  • Vegetable Peptase (50mg)
  • Methylsulfonylmethane (50mg)
  • Larch Arabinogalactan (50mg)

Looking at the ingredients, you can see their doses clearly on the label, which is good. Typically, many of these food supplements use proprietary blends, which are a mixture of ingredients that don’t disclose exactly how much of each ingredient you’re getting.

So, transparency is there. But do the ingredients in Lectin Shield actually work?

See for yourself:

N-Acetyl D-Glucosamine

Glucosamine is a molecule extracted from shellfish. It has joint soothing properties; specifically, it alleviates joint pain associated with arthritis.

N-Acetyl D-Glucosamine can also aid gut health by blocking the absorption of anti-nutrients in wheat.

As such, it’s a solid ingredient for a supplement called ‘Lectin Shield’. Although some studies suggest it may cause insulin resistance, this hasn’t been proven in more robust research.

The only annoying side effect of Glucosamine, ironically, is bloating and flatulence! [1]


Bladderwrack, or Fucus vesiculosus, is a brown seaweed. It’s a good source of iodine and L-Fucose compounds.

The latter are known for having anti-obesity, anti-oxidant and anti-inflammatory properties.

Bladderwrack isn’t the most effective ingredient for gut health specifically, though. It’d be better to replace it with something that aids gut health integrity and with that, shields from lectin’s effects.


D-Mannose is a simple sugar with only one sugar molecule. Naturally found in apples, oranges, peaches, green beans, and broccoli, it’s similar in structure to glucose.

D-Mannose is commonly used to treat urinary tract infections (UTI). Again, though, it’s not proven to block lectins or aid gut health in any significant way. [2]

Okra Fruit

Okra (ochro, Ladies’ fingers) is a plant with edible green seapods. Native to Africa and Southern Asia, Okra is prized for its impressive nutrient profile – containing beneficial antioxidants that aid heart health and can regulate your blood sugar.

However, once again, it’s an ineffective ingredient for blocking lectins. Although it has some fiber, it doesn’t quite belong among the best gut health ingredients.


This is not something you’ll commonly see in supplements, let alone gut health supplements.

Although potentially beneficial for skin health and cartilage, it’s a disguisting ingredient that won’t ‘shield’ you from lectins.

Sodium Alginate

Sodium Alginate is a compound extracted from brown seaweed. You’ll see it in commercially available cheeses, yogurts, and creams, where it’s used as a stabilizer and emulsifier.

This food additive can actually be beneficial for your gut, satiety, and digestion. It has a fiber-like effect.

Vegetable Peptase

Vegetable peptase is an enzyme that helps you digest proteins. Your body naturally makes peptase.

We rarely advocate using digestive enzymes as this can suppress your body’s own natural production.

In other words, once you stop taking digestive enzymes you may not be able to digest foods like you did before, and you may need to keep using them just to get back to normal.


Methylsulfonylmethane or simply MSM is a compound similar to glucosamine in effects.

It helps reduce joint swelling and pain in athletes and those who put their ankles through a lot of strain. [4]

Not the best gut health ingredient, though.

Larch Arabinogalactan

Larch Arabinogalactan is commonly found in some plants and bacteria. It’s a compound shown, in animal and cell studies, to aid the immune system.

However, very few if any human studies on this ingredient exist, and we don’t know if it is safe to supplement long-term.

Ironically, Larch Arabinogalactan has been reported to cause flatulence and bloating in some users. Making it a highly unreliable gut health ingredient.

How to Use Lectin Shield (Instructions)

Dosage directions for Gundry MD Lectin Shield are to take 2 capsules, twice per day, with two of your biggest meals of the day. Ideally, those that contain lectins.

Side Effects?

Gundry MD Lectin Shield uses a number of underresearched ingredients, some of which are known to lead to bloating and flatulence.

As such, it may actually worsen gut health in users who’re very sensitive to its ingredients.

The best way to check if it will work for you is by going to a qualified MD and showing them the ingredients of this product.

Based on your history, they should be able to tell whether you’re OK to take this product, as well as whether Gundry MD Lectin Shield has any drug interactions in case you take any medications.

Cost & Where to Buy?

Gundry MD Lectin Shield costs $79.95 on the official website. It’s also available on Amazon, GNC and other 3rd party sellers, as well as in stores such as Costco and Walmart.

Due to its wide availability, you can get Lectin Shield in the USA, UK, Australia, Canada and virtually any other country in the world.

The obvious downside of Lectin Shield is its massive price. With only a few high quality and proven ingredients in it, it’s not a great value for money either.

You could occasionally come across Lectin Shield discounts and coupon codes on the official website, but these seem to be rare.

Lectin Shield Reviews – What do Other Customers Say?

So, what do Lectin Shield reviews tells us? Are Lectin Shield results real or fake? The answer is, you can never tell where these types of testimonials come from. Especially those on Amazon where it’s easy to leave a review that makes the product look worse or better than it really is.

Lectin Shield Reddit reviews aren’t much better either. There are only a few of them that we’ve seen, and most of them are found in threads discussing lectins, gut health supplements, and GundryMD’s products in general.

Ultimately, it’s best to do your own research of the ingredients – this is the best way to know if a product is safe and if it will work for you.

Lectin Shield vs Total Restore – What’s Better?

Gundry MD Total Restore and Lectin Shield are completely different supplements in terms of effects.

Lectin Shield is more focused on protecting you from anti-nutrients in wheat, as well as reducing high blood sugars. Total Restore, on the other hand, is more focused on repairing and maintaining healthy gut cell integrity.

Both products have their downsides – the main one is that they’re both extremely overpriced. Apart from this, both are missing a few core ingredients that we so often see in the best gut health supplements.

But if we had to pick one, we’d go with Total Restore just because it has ingredients more effective for gut health overall, whereas Lectin Shield is unlikely to give you substantial benefits.

Gundry MD Lectin Shield Review Conclusion

This concludes our Gundry MD Lectin Shield review.

So, does Lectin Shield really work? Although some users claim to have debunked Lectin Shield’s reported benefits, these reviews could easily be faked.

On the other hand, if you look at the actual research behind Lectin Shield, many of them aren’t proven to work. A few do work, but they’re just beneficial for balancing your blood sugar. As for lectins – no, you still won’t be able to eat them if you’re intolerant – this product is unlikely to stop the bloating and other side effects.

Ironically, as we already said, some ingredients in Lectin Shield might make bloating and cramps worse. This is why, if you decide to buy this product, it’s best to start with only half a serving (1 capsule) to asses your tolerance.

As a whole, this product isn’t worth the almost $80 it’s asking. Saving money and investing it into something that uses safer, gentler and proven ingredients that work could be a wiser choice.

  • Some ingredients, such as N-Acetyl D-Glucosamine, can aggravate bloating
  • D-Mannose is a pointless ingredient – it’s used for urinary tract infections
  • $79.95 for 30 servings is more than double of what best gut health supplements charge

  1. Very good and informative review. I tried the product and you’re right about the bloating effect. I rather keep on using Total Restore, which is way better for my gut and (at least for me) doesn’t experience any side effects with it. Thank you.
