MICROPLASTIC DEFENSE PROTOCOL

Bloating after every meal? Brain fog by 2pm? Catching every cold? You're not aging — your gut wall is breaking down.

It's not the food.
It's the wall.

Microplastics are quietly weakening the tiny protein seals that hold your gut wall together. That's why the foods you've eaten for years now make you bloated, foggy, and tired — and why cutting one more thing out of your diet hasn't fixed it.

THE WALL · NOT THE FOOD

You didn't get more sensitive.
Your wall got more porous.

  1. 01

    The threat is real, and you can't filter your way out of it.

    Microplastics are now in human blood, breast milk, brain tissue, and arterial plaque. The 2024 New England Journal of Medicine study found them in the carotid plaque of 150 out of 257 patients — and those patients had 4.5× the rate of heart attack and stroke over the next three years.

    You can buy the glass containers. You can filter the water. You can swap the plastic cutting board. The exposure still happens — through the air, the soil, the food chain.

    We are not going to rid the Earth of microplastics. They are just too pervasive.
    Andrew Huberman · October 2024

    The damage is specific. It has a name.

    Inside your gut, microplastics quietly downregulate three protein seals — claudin, occludin, and ZO-1 — that hold your gut wall together cell-to-cell. These aren't wellness words. They're measured cell biology, peer-reviewed in 2021 (PMID 33904557).

    When those seals weaken, the wall starts to leak.

  3. 03

    This is what the leak feels like.

    Once the wall is breached, food fragments and LPS (a bacterial toxin from your own gut) start passing through the wall and into your bloodstream. Your immune system reacts to every leak the way it would react to an infection.

    The result is the daily list you already know:

    • Bloating after meals you used to tolerate
    • Brain fog by 2pm, even after coffee
    • Fatigue that sleep doesn't fix
    • Catching every cold, taking longer to shake it
    • Skin reactivity, joint stiffness, "off" days you can't explain
    You've got this swiss cheese gut barrier that's just letting good guys and bad guys in all the time. And your immune system is just exhausted.

    This is why what you've already tried hasn't worked.

    Probiotics add bacteria. They don't repair the seals between cells. Adding bacteria to a leaking ship doesn't seal the leaks.

    Elimination diets (gluten-free, dairy-free, low-FODMAP) reduce the trigger foods passing through the broken wall. But the wall stays broken. Reintroduce any food and the bloating comes back.

    "Detox" supplements sweep particles out of the gut lumen. They don't rebuild the damage that's already there.

    None of them rebuild the wall.

    The wall has a repair tool. It's the same one a newborn uses.

    When a baby is born, their gut wall is wide open. The very first thing they get from their mother — before regular milk — is colostrum. It's loaded with two things the wall needs to seal itself:

    • IgG antibodies — they wrap around the leak so toxins can't pass through while repair is happening.
    • Growth factors (IGF-I, EGF, TGF-β) — they tell damaged wall cells to rebuild the protein seals.

    Your gut wall doesn't lose this ability when you grow up. It just stops getting the signal.

    Tunicae Rebuild gives it the signal again — once a day, in one scoop.

THE SCIENTIST WHO DISCOVERED LEAKY GUT

The doctor who discovered leaky gut studied this molecule.

Dr. Alessio Fasano runs the Mucosal Immunology and Biology Research Center at Mass General. He's the scientist who discovered zonulin — the protein that controls how open or sealed those tight-junction seals are. He's the reason "leaky gut" stopped being a wellness word and became measured cell biology. In 2023, his lab co-authored a study on bovine colostrum and the gut wall. They found colostrum significantly upregulated three of the proteins that seal the wall — cingulin, claudin-12, and occludin (PMID 37834178). Six years earlier, the Hałasa human RCT (PMID 28397754) had already measured what that means in real bodies. After 20 days of supplementation, 75% of subjects who started with elevated intestinal permeability returned to normal range — measured by stool zonulin.

"The science isn't new. The mechanism isn't speculative. It's just been quietly sitting in PubMed while the supplement aisle sold you 400+ "bioactive nutrients" in a $119 jar."

WHAT REBUILDING THE WALL CHANGES

What rebuilding the wall actually changes.

One scoop, once a day. The wall regenerates every 5-7 days. Most people notice the first changes inside three weeks.

D1 · BLOATING RELIEF

Stop dreading what dinner does to you.

If every meal is a calculation — will this one bloat me, will this one wreck tomorrow morning — you're not eating wrong. You're eating through a wall that can't hold its seals.

When the wall reseals, food stops being a trigger. The Hałasa RCT measured intestinal permeability normalizing in 20 days. ARMRA's own internal survey reports 86% of users experiencing less bloating — and ARMRA's positioning never even told them what the wall was. Tunicae names the molecule, names the dose, and gets out of the way.

  • “My digestion, focus, energy and overall well-being is benefitting and I've seen so many results immediately.”

D2 · BRAIN FOG REVERSAL

Your brain fog has a gut address.

You're not getting dumber. You're not "just aging." When the gut wall leaks, the inflammation signal travels — through the vagus nerve, through the bloodstream, into the brain. That's what brain fog actually is: an inflammation signal your brain is trying to read as thought.

Andrew Huberman covered the gut-microplastics-IBS correlation in his October 2024 episode. Higher microplastic levels in the stool of people diagnosed with IBS — and IBS is one of the strongest predictors of brain fog there is. The gut and the brain aren't two separate systems. They never were.

Seal the wall, the inflammation signal stops, the fog lifts.

  • “It has helped with my muscles, mental clarity and overall health.”

D3 · DAILY SAFETY NET

A daily way to handle what you can't avoid.

You filtered the water. You swapped the containers. You read the label. You're still being exposed — through the air, the food chain, the soil. Nobody is winning the avoidance game.

What you can do is give your gut wall the rebuild signal every day, so the exposure that does get through doesn't break the seals faster than your body can repair them. One scoop, mixed in water, before breakfast. Less than 90 seconds.

  • “I feel like it's a safety net for all the unknown microplastics I'm ingesting — no matter how careful I think I'm being.”

  • “It feels better than doing nothing about it.”

D4 · RESTORATION

It's not too late. The damage is reversible.

The microplastics already in your tissues are not coming out. Nobody can honestly tell you otherwise.

But the damage to the gut wall — that's reversible. Your gut wall regenerates every 5 to 7 days. Every cell in it is replaced. The only thing it needs is the right signal to rebuild the seals correctly when it does.

If you've felt for years like "I just haven't been the same since" — since the antibiotics, since the pregnancy, since the long COVID, since the year you can't put your finger on — this is the layer underneath that feeling. The wall stayed open. It's been waiting for the signal.

  • “We are not going to rid the Earth of microplastics. What we can do is limit their introduction and accumulation in our bodies.”

THINGS PEOPLE ASK BEFORE THEIR FIRST ORDER

The questions before the click.

Isn't "detox" kind of made up? My liver does that.+

Yes — your liver and kidneys handle systemic detox just fine. We're not claiming to detox anything. We're claiming to rebuild the gut wall the microplastic exposure is tearing down. Different mechanism, different problem, different fix.

Is "leaky gut" even a real diagnosis?+

The phrase isn't a clinical diagnosis, you're right. But the underlying biology is. Tight-junction proteins — claudin, occludin, ZO-1 — are measured cell biology in peer-reviewed journals, not wellness vocabulary. When those proteins are downregulated, the wall is more permeable. That's measurable, in humans, with stool zonulin and the lactulose/mannitol ratio.

I read that bovine colostrum is "unfounded" for adults.+

That critique is usually pointed at vague immune-boosting claims. Tunicae's claim is specific: bovine colostrum upregulates the proteins that seal the gut wall. The Hałasa 2017 RCT measured stool zonulin normalization in 75% of subjects with elevated permeability — in humans, peer-reviewed (PMID 28397754). And the Fasano-co-authored 2023 paper measured the upregulation directly. The science exists. It's just not loud yet.

I don't want to take something that's stealing from baby cows.+

Neither do we. Tunicae sources only overflow colostrum — the surplus the calf doesn't need after its first feed. Calves get fed first. Always. This is non-negotiable on our supply side.

Are supplements just expensive urine?+

Some are. The "expensive urine" critique applies to nutrients that need to be absorbed into the bloodstream to work. Colostrum's IgG and growth factors do their work in the gut lumen — they don't need to be absorbed systemically. They bind toxins and signal repair right where the wall is leaking. Different category of supplement, different rules.
