BIOptimizers Microbiome Breakthrough

Leaky Gut GuardianŽ has a new name: Microbiome Breakthrough. A powerful combination of IgYmaxŽ and synbiotics (probiotics and prebiotics).

It is synergistically designed to weed out bad bacteria and reseed the good ones, as well as repair the gut lining.

How Do You Know If Your Immunity Is Being Weakened By Leaky Gut?

150g | 30 x 5g servings

Have you ever eaten the standard Australian diet (processed food) for a period of time?

 Have you ever consumed tap water on a regular basis? (even if you don’t anymore)

 Have you ever eaten sugar (including soda) regularly for a period of time?

 Have you ever taken antibiotics, either as an adult or a child?

 Have you ever had wheat or dairy as a regular part of your diet?

 Have you consumed tuna, sushi or mercury-containing foods on a regular basis?

If the answer is YES to one or more of these questions, research shows that toxins in these substances likely create “leaks” in the gut. 70% of your immune system is in your gut. So if you’re serious about immunity, this is something that must be addressed.

LEAKY GUT GUARDIANÂŽ can help repair compromised gut-lining, help it rebuild with the right probiotics and prebiotics and activate the four critical pathways to super immunity. Available in either Vegetarian Vanilla or Carnivore Chocolate.


A smooth, creamy, vanilla flavour that is delicious all by itself with water—but also goes well in any shake or smoothie... and even latte-style drinks that are not overly hot. This is suitable for vegetarians (but not vegans, due to the egg-based IgY Max®.). Vanilla flavour: Vegetarian, Gluten Free , Dairy Free, Contains Egg


If you’re NOT vegetarian, you have an additional option and even more benefits... as the chocolate version contains both collagen and bone broth —to further help fortify gut health. A recent study found that collagen peptides were able to prevent further breakdown of the intestinal lining. And as a natural source of glutamine and gelatine, bone broth can help maintain the integrity of the gut mucosa and intestinal barrier. Carnivore Chocolate flavour: Gluten Free, Dairy Free , Contains bovine collagen and bone broth

30 x 5g servings (scoops) per jar.

  • I discovered a way to fix the “holes” in my leaky gut using 3 simple nutrients... Let me walk you through them, one-by-one so you can heal your gut and upgrade your immunity...


    Found In Your Fridge This is essential to sealing any holes in your gut. Immunoglobulins are a class of proteins which are formed by your immune system in reaction to certain foreign substances. They are quite frankly some of the most powerful nutrients in existence. Your body is specifically designed to recognise and USE immunoglobulins to help in the fight against pathogens.

    But here’s the REALLY amazing part: Specific immunoglobulins found in eggs have superpowers—especially when it comes to your gut. In fact, one study conducted on an egg-based immunoglobulin—called IgY—found mind-blowing results: Initially, the majority of subjects reported “a decrease in gas and bloating” and “felt more energy”... Yet the most incredible result of all was the 95% decline in the occurrence of something called Zonulin—which shows up when there is excess intestinal permeability (holes in the gut lining)...

    That means you... Take This Nutrient, And Up To 95% Of The “Holes” In Your Gut Get Sealed... Truly amazing. Plus, subjects saw a 290% decline in gut inflammation—which speaks to how this rare compound delivers further benefits to your immune system, digestion, and more. Now, you *could* definitely get more of this nutrient by eating more egg yolks—but there’s a problem... These egg-based immunoglobulins are very sensitive to heat — so cooking up some delicious eggs isn’t that helpful... Plus, to get enough of these immunoglobulins to actually repair gut lining and for them to pass through your entire gastric environment, with all of the acids it produces... These immunoglobulins need to be attached to special sugars so they can reach your gut lining fully intact, which is where IgYmax® comes in.

    GUT-IMMUNITY NUTRIENT #2: Rare “Repairing”Probiotic Strains

    Once the lining in your gut is no longer excessively “permeable” (riddled with holes)... you’re ready for the next step. Years and years of gut issues have left most people with a very toxic imbalance of bad microbes relative to the good guys.

    And in this altered environment, where food tends to rot and putrefy more, the problem tends to get worse with time... Luckily, in my work with thousands of clients and follow-up research with our team... We uncovered the EXACT probiotic strains needed to kickstart this repopulation process... This way, your gut lining is filled with all the good bacteria needed to help you build super immunity... This includes:


    A probiotic bacteria native to your gut, but hard to find in food sources... and not common in other probiotic supplements. The early research on Lactobacillus Rhamnosus is pretty incredible: In one study, orally administered Lactobacillus rhamnosus modulates the respiratory immune response triggered by the pathogens... A study by doctors in Finland found that it directly helps activate immune response in the gut... Another study found that Lactobacillus rhamnosus is critical for rebuilding damaged gut health...


    A probiotic that helps the body by suppressing harmful bacteria, which, in turn, enhances immune function and aids in digestion. This is another essential strain for rebuilding your gut-immunity connection and early research is beyond impressive.

    In a study published in the Academic Press Journal, the researchers found that Lactobacillus gasseri potentiates immune response against infection. Initial animal studies have found that Lactobacillus gasseri inhibits tissue inflammation and intestinal permeability —making it powerful in the gut-rebuilding process. And when scientists in Korea studied this strain, they found that it reduced inches around the waist and hips in human subjects.


    A type of lactic acid bacteria, naturally found in the gut, shown to enhance protection against pathogens and modulate immune responses. This is the third and final probiotic strain ESSENTIAL to the gut-rebuilding process:

    A study published in the journal Nutrition found that Lactobacillus helveticus significantly improved immune response in elderly people... Another study published in the Frontier Journal of Microbiology showed that Lactobacillus helveticus was able to induce immune response and exert a protective effect against Salmonella Typhimurium and E. coli...

    And finally, a study published in the American Society for Microbiology showed how Lactobacillus helveticus works with a protein in your body to modulate and properly stimulate innate immunity.

    GUT-IMMUNITY NUTRIENT #3: Feed The Good Guys Starve the Bad Guys With Powerful Prebiotics

    The last step is simply to add prebiotics—which are nutrients/fuel for your friendly bacteria—to accelerate the regrowth and rebuilding process. Unfortunately, not all prebiotics are created equally... so you need to be careful which ones you incorporate.Science says these are most effective:


    A naturally occurring polysaccharide sugar produced by many types of plants, which cannot be absorbed as a carbohydrate, and instead feeds friendly bacteria in your gut. Inulin has some very impressive research behind it:

    One study on inulin (and its fermentation metabolites) found that it boosted gut barrier and immune function of porcine intestinal epithelial cells...

    A study published in the prestigious British Journal of Nutrition found that Inulin prebiotics directly helped modulate immunity function in humans...

    And just like the probiotic strains we covered a moment ago, a study found that inulin can help with weight management and ectopic fat with subjects who have blood sugar issues... Now, there are even more prebiotics you could add to this mix—but this is a great start. Especially because this 1-2-3 combination goes beyond just restoring your gut-immunity connection. It helps activate ALL FOUR critical pathways necessary for “super immunity.”



    Studies have shown that a healthy gut lining is teeming with good bacteria that form a stable community of protection. One role of these “protectors” is to resist and kill invading, non-native bacteria and other pathogens.


    A study published in the Journal Microbes found that a healthy gut, one that is not overly permeable and has the right balance of bacteria, helps maintain “immune homeostasis.” This means it helps you naturally regulate overall immune response throughout the entire body — something other solutions cannot do because they don’t directly address the gut-immunity connection.


    This last pathway is perhaps the most powerful, especially when it comes to foreign pathogens. Earlier, you learned that immunoglobulins are Y shaped molecules that play a direct role in defending against “bad guys.” Immunoglobulins are found in the openings through which outside organisms can enter your body, as well as blood and lymph fluids. That makes them the first line of defence against invading organisms like viruses and bacteria.
