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 by placing 1 scoop in 4 ounces of water 2 times daily. Or as recommended by your health professional.

    We used Ultra Immune for years to help with accidental gluten contamination and loved it. When it was replaced with Immune Shield, we were skeptical, but desperate, so we decided to try the new product. The small bottle and small dosage were a surprise, but to our delight, it’s a wonder working supplement! One small scoop of powder (2.5g) mixed in 4 ounces of water, gives us almost immediate relief from contamination symptoms! We’ve tried other products, but none of them compare to Immune Shield. It really works! Thank you, Dr. Osborne. We will be keeping this product on hand always.

    Half way through, seems to be doing it’s job. Time will tell, I will keep you posted. Dr. Osborne you are doing a Great Job keep up the good work. You do not find many DR’s that are willing to give up there time and try and help other people with auto immune issues.

    I have finished one container about to start on next one. I like this product. I am having regular stools and it helps relieve the itchiness when I am exposed to gluten. I plan to keep using it along with Dr. Osborne’s other supplements. All his products are high quality.

    I am on second container. Seems to be working. Very pleased with it. Easy to take and I haven’t had acid indigestion lately. But, also avoiding high lectin-type foods.

    I used to have a lot of gut-intestinal problems when a naturophatic doc told me to stop eating grains, which I did, about 5 yrs ago. Then I learned from Dr Osborne that the immune system may mistake dairy protein for gluten and cause a reaction. I also found out that one of my medicines had cornstarch gluten in it, so I switched the medicine, and after a 4 day water fast I switched from Paleo diet to Ketogenic, minus the dairy. I have been taking the Immune Shield Powder for a few weeks now and feel good. I have not done any gut tests, I don’t have any proof that what I am doing for my health is actually helping, other than that I feel better, but I am not 100% okay, just yet (b/c of oral Candida, a bladder disease/IC w chronic pain for 13 yrs, and IBS which I am taking another powder for). I don’t trust regular doctors b/c they almost killed me with chemo for breast cancer(the cancer was taken out in a surgery but they recommended chemo and back then I didn’t know what I do now, 20 yrs later), so I will continue trying to heal myself. I appreciate Dr Osborne very much!

    I am using this product to heal and repair the intestinal permeability related to the autoimmune condition for my thyroid. I have experienced an improvement in my skin already and anticipate this will address my intestinal health too.

  8. Michele W.

    hard to dissolve in hot liquid (decaf coffee) not bad taste though

  9. Melissa K.

    I have been using this product to raise my Immunoglobulin levels during chemotherapy and immunotherapy treatments, which made my levels low. My oncologist wanted me to have an infusion of immunoglobulins, but I wanted to try this first. My levels are consistently improving at each monthly appt.. So happy I tried this first!
