How Ideal Immunity® Works

Section Image

The strength of our immune system determines our overall state of health and is shaped by the condition of our gut microbiome. Seventy percent of the immune system is in the gut. Balanced and diverse bacteria in the gut benefits our body’s immunity, brain function, skin, and digestion. Ideal Immunity® targets the way the gut microbiome interacts with the immune system.

We are constantly being challenged by pathogens and environmental toxins that tax the body and impact our immune system. Strengthening the lining of the gut provides the critical immune barrier to keep you healthy.

This six-strain formula includes three keystone strains that are proprietary to us and work in harmony with the other strains to form a stable, sustainable community that allows the gut microbiome to produce the necessary metabolites to optimize the immune system. This formula was designed to help reduce the pathogen load, provide molecules to stimulate the immune system, reduce inflammation and produce antioxidants. Together, this special formula improves immune function and helps restore a healthy gut-microbiome.

By increasing the production of butyrate to protect the gut lining, Ideal Immunity® fortifies mucosal surfaces and adjusts pH to give your immune system the boost its craving.

Take 2 capsules per day. We recommend taking 1 in the morning and 1 around dinner time. Do not take if you are taking MAO or SSR inhibitors.

We believe in the transformative potential of Ideal Immunity® and want you to feel confident in giving it a try. That’s why we offer a satisfaction guarantee. If you’re not completely satisfied with how you feel after using our product, simply contact us within 30 days of your purchase, and we’ll refund your full purchase price.

This is our way of supporting your health journey—so you can take this important step toward better wellness with confidence.

health suffers. That’s why you don’t want buy basic probiotics. You need just the
right team of bacteria to get to work and bring back harmony in your gut.

  • Bacillus subtilis (DE111® by Deerland):
    Promotes enhanced immune function and pathogen control.
    Helps with both diarrhea and constipation by maintaining healthy digestion and nutrient uptake.
    Increases muscle mass and reduces body fat.
  • Bifidobacterium bifidum:
    Interacts with immune system by producing a variety of molecules that act as essential communicators with the immune cells in the mucosal lining of the gut.
    It also stimulates growth of other commensal bacteria that produce butyrate to support the gut lining.
  • Lactobacillus plantarum (TBC LP-36™):
    Breaks down acetaldehyde which can damage membranes and produces butyrate which protects the gut barrier.
    It is effective in controlling pathogens, by producing potent antimicrobial peptides.
    Our strain is unique in its ability to degrade glyphosate to carbon, phosphate and water and sequesters and removes heavy metals such as aluminum.
  • Lactobacillus reuteri (PCR07):
    Makes antimicrobial substances
    Converts glucose to mannitol
    May reduce the production of pro-inflammatory cytokines.
    Associated with increased production of oxytocin, the love hormone
    Can help accelerate wound healing.
  • Lactobacillus ruminis (TBC LR-73™):
    Has the central role of immune and pathogen control through the production of antimicrobial substances.
    This unique strain is especially beneficial against foodborne pathogens like Listeria and Salmonella.
  • Leuconostoc mesenteroides (TBC LM-37™):
    Is the principal converter of glucose and fructose into mannitol
    Produces anti-inflammatory substances
    Protects the gut lining
    Makes vitamin B12. B12 keeps nerves and blood cells healthy and helps make DNA and red and white blood cells. White blood cells are critical for a healthy immune system.

    Our formulas are balanced for sustained action, which means they work longer and are stronger. Restore the balance of bacteria in your gut and rediscover your best health.

    THE ABSOLUTE best ever!

    I have been making yogurt for close to 3 years now in following of the expert guidance of Dr. William Davis. It is also how I discovered Biotiquest and the probiotics that Martha Carlin has engineered for us. I have benefited greatly from adding Sugar Shift to my daily routine. It was about a month ago that I decided to try Ideal Immunity (II). I can say beyond a doubt that the yogurt I fermented using these combined strains is THE ABSOLUTE best I have ever tasted, and reliably so. My II yogurt has become a key joy in my healing regimen - a joy for which my immune system thanks me daily!

    Ideal Immunity Review.

    Haven’t really been able to tell any difference. Unfortunately I recently switched my Carbidopa/ levadopa meds to Cexont so that is having some changes in my symptoms. I take a Sugarshift and an Ideal Immunity in the morning after breakfast and another Sugarshift at night before bed. Should I do something different?

    Hi Andy,
    Thank you for sharing how things have been going. Changes in medication—especially ones like Carbidopa/Levodopa—can shift the body’s rhythms in unexpected ways. You’re already doing meaningful work by supporting your gut microbiome with Sugar Shift and Ideal Immunity.

    Please keep an eye out for an upcoming email from our founder, Martha. She’ll be sharing something we think you’ll find insightful.

    With Gratitude,
    Jack

    My son and I got the typhoid vaccine. I was concerned because I remember taking this vaccine 30 years ago. Back then my stomach bloated and hurt! This time neither of us had symptoms as we took one of these per day!
