Enhance Gut Health And Reduce Toxins

Your body’s immune system protects you from infections and disease. When the immune system is compromised, your body starts attacking healthy cells. This is what’s known as autoimmune diseases.

Autoimmune diseases are on the rise.

Recent research shows a connection between autoimmunity and intestinal permeability. Or “Leaky Gut”. A condition where your gut doesn’t catch everything it’s designed to. The lining of your gut isn’t as tight as it should be so harmful substances ‘leak’ through.

When microbes and toxins leak through your gut, your immune system kicks in. As more and more particles enter your system, your immune system is on overdrive. This causes a drop in immune tolerance.

To restore healthy immune function, you must reduce the burden on your immune system.

How do you start?

The GI tract acts as the gateway to the rest of the body. This makes the health of the gut barrier critical to your health. Environmental triggers like poor diet, and toxins can lead to GI challenges.

Probiotics are a natural choice for supporting beneficial bacteria in the gut. Immune Shield works to knock out unwanted microbes and toxins. This further enhances microbiome balance and facilitates gut barrier strength.

What makes Immune Shield so powerful?

Immunoglobulins. Protein molecules that that contain antibody activity. The most abundant class of immunoglobulins in the blood is Immunoglobulin G (IgG).

Immune Shield contains Serum-derived bovine immunoglobulins (SBI). SBI provides the highest concentration of bio-available IgG for immune challenges. Especially where allergens are a significant concern.

It is the only source of purified, dairy-free immunoglobulin G available as a dietary supplement. Immune Shield helps to maintain a healthy intestinal immune system. It binds a broad range of microbes and toxins within the gut.

Immune Shield binds to microbes and toxins. Eliminating them before the immune system activates. This reduces the stress on the immune system.

70 – 80% of all pathogens enter the body through the mouth and GI tract. Adding Immune Shield to your daily supplement regimen is a fast and immediate way of sending in reinforcements to your immune system.

Why Serum-derived Bovine Immunoglobulins (SBI)?

Several studies explain that oral administration of SBI with high levels of IgG help:

  • Improve weight management
  • Normalize gut barrier function
  • Improves immune function
  • Improves composition of the GI microflora
  • Enhances digestive processes
  • Neutralize bacterial toxins
  • Decrease intestinal inflammation

For Best Results

Immune Shield works best taking 4 capsules daily with food. Or as recommended by your health professional.

    Great product – my nutritionist is using it to more gently help me to overcome some bacterial infections in my gut. I’d much rather use this product than harsh antibiotics!

    Digestion seems to be better.

  12. Karen T.

    works for me!

  13. .

    I like the product as we travel a lot and it is hard to make sure our food is completely gluten free.


    This was added to help the healing process with Intestinal permeability. While I’ve only been taking it for a couple weeks, it has had noticeable positive effects on my digestion. I’ll continue to take it for a few months & return to add my comments. Hard to assess in such a short time.

    I’ve been on this for over a month now & seeing a difference. So grateful for all your products. They are making a big difference in my well being! 🙏
