Gut RestoreX - Ultimate Microbiome Barrier Support
Gut RestoreX · Microbiome & Barrier Support
Two ingredients. One of them is dosed exactly the way it was studied.
Most gut powders are long ingredient lists at doses nobody researched. Gut RestoreX is the opposite: 2,000 mg of IgY Max hyperimmune egg powder — the same daily amount used in the published human work on this ingredient — plus 800 mg of larch arabinogalactan fiber to feed the bacteria you want to keep. No fillers. No sweeteners. No flavors. Nothing else in the scoop.
How this one is made
Manufacturing and standardization
We are specific about what we can document for this product, and we do not borrow language from anywhere else in the line. Here is exactly what stands behind the scoop in this bottle.
01
Made in the USA, FDA-registered facility
Manufactured in a United States facility that is registered with the FDA and operates under current Good Manufacturing Practice regulations for dietary supplements.
02
Licensed branded immunoglobulin
The hyperimmune egg powder is IgY Max, a branded, standardized raw material produced by IgY Nutrition, LLC and used under license. Not a generic egg protein.
03
Nothing hiding in the scoop
2,000 mg of IgY Max plus 800 mg of arabinogalactan equals 2,800 mg — the entire 2.8 gram scoop. Other Ingredients: None. There is no room for anything undisclosed.
04
No proprietary blend
Both actives are listed at their exact amounts on the panel. You can compare our doses to the published research yourself, which is the whole point.
The short version
What it is
An unflavored, two-ingredient powder combining hyperimmune egg powder (IgY Max) with larch arabinogalactan, a soluble prebiotic fiber. One scoop daily in a cold beverage.
What it does
Delivers antibodies raised against 26 microbial strains directly to the gut lining, where they act locally. Supports gut barrier integrity, a balanced microbial population, and a healthy inflammatory response.
Who it's for
Adults who want foundational gut support: people rebuilding after a rough stretch of eating or travel, hard trainers under GI stress, and anyone who tolerates eggs and wants passive immune support at the mucosal level.
How to take it
One scoop daily in 6 to 8 oz of cold water, juice, or a cold shake. Never mix into hot liquid or cook with it — heat degrades immunoglobulins. Consistency matters more than timing.
The difference
Fewer ingredients is the harder formulation problem.
Anyone can put twenty things on a label. Putting two things on a label means both of them have to earn the space.
The industry standard
- A dozen gut ingredients at fractional doses, buried inside a proprietary blend
- Sweeteners, gums, natural flavors, and anti-caking agents making up most of the scoop
- Immunoglobulins listed as a generic "egg protein" with no source, no standardization, no license
- Study percentages quoted on the label without ever stating the dose those studies used
- Amino acid and herb doses too small to match any published human research
The IOH standard
- Two actives, both disclosed at full amount, no blend to hide behind
- Zero fillers, zero sweeteners, zero flavors — the scoop is 100 percent active material
- A named, licensed, standardized branded immunoglobulin: IgY Max
- We tell you the dose the research used, next to the dose in the bottle, even when they do not match
- The primary active is at 2,000 mg per day — the amount used in the published human work
What it supports
Four jobs, one scoop.
01
Gut barrier integrity
The single cell layer lining your intestine decides what gets into circulation and what stays out. IgY antibodies work at that surface, supporting the structural integrity of the gut wall without being absorbed themselves.
02
Passive immunity where it counts
Roughly 70 percent of immune tissue sits along the digestive tract. These antibodies are not absorbed into the bloodstream. They stay in the lumen and act locally, which is exactly where mucosal defense happens.
03
A microbial population worth having
Arabinogalactan is fermented by resident bacteria into short-chain fatty acids, principally butyrate — the preferred fuel of the cells lining your colon. It supports Lactobacillus and Bifidobacterium populations.
04
A healthy inflammatory response
IgY antibodies do not activate the human complement system and are not associated with a rise in inflammatory cytokines, which is part of why they can support immune activity at the gut surface without adding to inflammatory load.
Signature section · The dose ledger
Here is our dose next to the research dose. Both of them.
Most brands only show you this comparison when it flatters them. We are showing you both ingredients, including the one where we come in under the studied range, because you should be able to decide for yourself instead of taking our word for it.
IgY Max hyperimmune egg powder
Dose matched
The human work on this specific branded ingredient used 2 grams of hyperimmune whole egg powder per day, taken over an eight week period, looking at gut permeability markers, microbial composition, and inflammatory markers. One scoop of Gut RestoreX delivers that same 2,000 mg. Not a fraction of it. Not a "clinically inspired" gesture toward it. The amount.
Straight talk
The published dataset behind IgY Max is small and largely sponsored by the ingredient supplier, and some of it lives in patent filings and company reports rather than peer-reviewed journals. That is a real limitation and I am not going to pretend otherwise. What I can tell you plainly is that the dose in this bottle is the dose that was actually tested, which is more than most gut products on the shelf can say about anything in them.
Larch arabinogalactan
Below the studied range
This is the part other brands would quietly skip. The human immune research on larch arabinogalactan used 1,500 to 4,500 mg per day. The gastrointestinal work — the studies showing increased fecal anaerobes, increased Lactobacillus, and reduced fecal ammonia — used 15 to 30 grams per day. Gut RestoreX contains 800 mg. That is a supporting dose, not a therapeutic prebiotic dose, and we are not going to attach those study results to it.
Why we did it this way
We built this formula around the immunoglobulin, and the fiber is here to do one specific job: give the beneficial bacteria something fermentable to work with while the IgY is doing its work at the barrier. Putting 15 grams of fiber in the scoop would have meant a 17 gram serving, a gritty drink most people quit inside a week, and a bottle that lasts twelve days. If you want a full prebiotic fiber dose, add it deliberately on top — that is a conversation worth having with your practitioner, not something we should hide inside a scoop.
Inside the formula
Two actives. Nothing else in the scoop.
Hyperimmune Egg Powder
2,000 MG
IgY Max · from Gallus gallus · antibodies raised against 26 microbial strains
Hens are repeatedly immunized against a defined panel of 26 human-relevant microbial strains. Their immune systems generate antibodies, and those antibodies concentrate in the eggs. The eggs are gently processed into a whole egg powder that carries that polyvalent antibody profile intact. Most other IgY products on the market are monovalent, meaning they target a single organism. This one is polyvalent across 26.
The functional point is that IgY is not absorbed into your bloodstream. It works in the lumen — the open channel of the intestine — where it binds to microbial surface structures and interferes with adhesion to the gut wall. Bacteria that cannot adhere cannot colonize, and they move on through. Beneficial commensal organisms are not targets of this antibody panel, which is why the mechanism is selective rather than indiscriminate the way a broad antimicrobial would be.
- Supports the structural integrity of the intestinal barrier
- Supports passive mucosal immunity at the gut surface
- Supports a favorable balance of resident gut organisms
- Supports a healthy inflammatory response — IgY does not activate the human complement system
What I tell patients
This is the ingredient I reach for when someone's gut has taken a beating and I want to support the barrier without throwing a dozen herbs at it first. It is quiet, it is food-derived, and it does not fight with much. If you cannot have eggs, this is not your product, and no amount of wanting it to work changes that.
Arabinogalactan
800 MG
From larch (Larix species) · soluble prebiotic fiber
Larch arabinogalactan is a highly branched polysaccharide — a galactan backbone with arabinose and galactose side chains — that human digestive enzymes cannot break down. It arrives in the large intestine intact, where resident bacteria ferment it into short-chain fatty acids, principally butyrate and propionate. Butyrate is the preferred energy substrate of colonocytes, the cells that make up your colon lining. In practical terms, you are not feeding yourself with this fiber. You are feeding the bacteria that maintain the wall.
At the 15 to 30 gram doses used in the published gastrointestinal research, arabinogalactan increased total fecal anaerobes and Lactobacillus species and lowered fecal ammonia. Gut RestoreX contains 800 mg, well under that range, so treat those specific findings as background on the ingredient rather than as claims about this product. At 800 mg the fiber is functioning as a fermentable substrate alongside the immunoglobulin, and the practical benefit most people notice is simply that the powder does not sit heavy.
- Supports the growth of beneficial gut bacteria as a fermentable substrate
- Supports short-chain fatty acid production by resident microflora
- Supports a healthy intestinal environment
- Counts toward daily soluble fiber intake

Honest expectations
What the first 90 days usually looks like.
Nobody can promise you a timeline, and I will not. Gut tissue turns over on its own schedule and yours is not mine. Here is the honest shape of it, based on what I see clinically.
Days 1 to 14
Establish the habit, notice the tolerance
The first thing you are checking is whether it sits well. Most people find it neutral to the point of forgettable — no bloat, no urgency, no aftertaste. Some people notice a change in regularity in the first week or two. Some notice nothing yet, which is normal and not a failure.
Days 15 to 45
The quieter middle
This is where the barrier and microbial work happens and where most people quit, because "less noticeable digestion" does not feel like an event. Comfort after meals, less gas, and steadier days are the kind of thing you usually recognize in hindsight rather than in the moment.
Days 46 to 90
Whether it earned its spot
The published work on this ingredient ran eight weeks, so give it at least that before you judge. At 90 days you will have a real read: keep it in the rotation, or stop and see whether you miss it. That second test is the honest one, and I recommend it.
Taste and mixability
It is unflavored, and that is on purpose.
What it tastes like
Faintly eggy, mildly savory, essentially neutral in anything with flavor of its own. In plain water you will notice it. In juice, a smoothie, or a cold protein shake, it largely disappears.
How it mixes
Stir or shake into 6 to 8 oz of cold liquid. Arabinogalactan is highly water soluble. The egg powder disperses well but likes a shaker bottle or 15 seconds of stirring more than a lazy swirl with a spoon.
Why no sweetener
Adding stevia, flavor, and gum would have meant a bigger scoop with less active in it, and would have put sweeteners into a product designed for people rebuilding a microbiome. We left it out.
Do not use hot liquid. Do not stir this into coffee, tea, soup, or oatmeal, and do not bake with it. Immunoglobulins are proteins, and heat denatures them. Cold liquid or cold food only — that instruction is not fussiness, it is the difference between the product working and the product being expensive egg powder.
What to look for
How to read a gut powder label before you buy it.
Use these on any product in this category, not just ours. If a label will not answer these questions, that is the answer.
| What to check | Gut RestoreX | Typical off-the-shelf gut powder |
|---|---|---|
| Immunoglobulin source | IgY Max, a named and licensed branded hyperimmune egg powder, polyvalent across 26 strains | Generic "egg protein" or "immunoglobulin concentrate" with no source or standardization named |
| Dose vs. published research | 2,000 mg daily — the amount used in the human work on this ingredient | Dose not stated, or stated inside a blend so it cannot be compared to anything |
| Proprietary blends | None. Both actives disclosed at exact amounts | Common. One number covering six to fifteen ingredients |
| Non-active ingredients | Zero. Other Ingredients: None | Sweeteners, natural flavors, gums, silica, maltodextrin, anti-caking agents |
| Added sugar or sweetener | None of any kind, natural or artificial | Stevia, monk fruit, sucralose, or cane sugar in most flavored versions |
| Scoop math you can verify | 2,000 mg + 800 mg = 2,800 mg = the full 2.8 g scoop | Scoop weight and active totals rarely reconcile once fillers are counted |
| Servings per container | 60 — a full two months at one scoop daily | 20 to 30 servings is the common size in this category |
| Study doses disclosed | Stated for both actives, including where our dose sits below the studied range | Percentages borrowed from studies run at doses the product does not contain |

From the founder
Why we formulated this one.
"I have spent 33 years watching people chase gut health with fifteen-ingredient powders that never disclose a single dose. We formulated Gut RestoreX the other direction on purpose: put the primary active at the exact amount it was studied at, tell you what the fiber can and cannot do at 800 mg, and take everything else out. I take a scoop most mornings in cold water. It is not the product that makes people say 'wow' in week one — it is the one that quietly holds the floor while everything else you are doing has a chance to work."

What it pairs with.
Gut RestoreX is the foundation layer. These are the three products I most often build around it.
Probiotic 40
The natural partner. The published work on hyperimmune egg powder specifically looked at pairing it with a probiotic, on the logic that clearing adhesion sites and seeding beneficial organisms are two halves of one job. Take them at the same time of day, both in cold liquid.
View Probiotic 40AceX Glutamine
Where Gut RestoreX supports the barrier from the lumen side, glutamine supports the enterocytes themselves as a primary fuel substrate. This is the pairing I use for people whose gut has been under sustained stress from hard training, travel, or a long stretch of poor eating.

For a defined reset window rather than daily maintenance. Run GI Clear Elite through its course while Gut RestoreX stays in place underneath it, then keep Gut RestoreX going once the reset is finished.

Questions, answered.
I have an egg allergy. Can I take this?
No. This product is made from whole hyperimmunized egg powder and the entire mechanism depends on egg-derived antibodies. There is no version of this that is safe with an egg allergy, and there is no processing step that removes the allergen. If you have an egg allergy or sensitivity, skip this one entirely and talk to your practitioner about non-egg options.
Medications and health conditions: what should I check first?
Talk with your physician or pharmacist before starting if any of the following apply to you.
Immunosuppressant drugs. If you take medication intended to suppress immune activity — including after an organ or tissue transplant — do not start this product without clearing it first. Arabinogalactan has been associated with immune-stimulating activity, and the theoretical concern is that it could work against what the medication is doing.
Autoimmune conditions. For the same reason, if you have an autoimmune condition, this is a conversation to have with the physician managing it before you add an immune-active ingredient.
Oral medications taken on a strict schedule. Soluble fiber can influence the absorption of some oral drugs. The 800 mg here is a small amount, but if you take thyroid medication, an oral anticoagulant, or anything else where consistent absorption matters, separate this from your medication by a couple of hours as a matter of routine.
Pregnancy and nursing. There is not enough data on larch arabinogalactan in pregnancy or nursing to say it is fine, so we will not say it is fine. Do not use without your physician's approval.
This list is not exhaustive and it is not a substitute for a conversation with the clinician who knows your chart.
Why can't I put it in hot coffee or oatmeal?
Because immunoglobulins are proteins, and heat unfolds proteins. Denatured antibodies lose the three-dimensional shape that lets them bind their targets, which is the entire point of the ingredient. The label instruction to use cold liquid is not a texture preference. Use cold water, juice, a cold shake, or sprinkle it on cold food such as yogurt or a salad.
Is 800 mg of arabinogalactan really enough to do anything?
Not enough to reproduce the published prebiotic research, and we say so on this page rather than hoping you do not check. The human gastrointestinal studies used 15 to 30 grams per day, and the immune studies used 1,500 to 4,500 mg. At 800 mg the fiber is a fermentable substrate supporting the primary active, not a standalone prebiotic dose. If you want a full prebiotic fiber dose, add one deliberately on top and talk it through with your practitioner. We would rather you know that than find it out later.
Will this affect my cholesterol? The panel lists 33 mg.
Each serving contains 33 mg of dietary cholesterol from the whole egg powder, listed on the panel at 10 percent of the Daily Value. For most adults that is a modest amount — roughly a fifth of a large egg. Dietary cholesterol influences blood cholesterol far less than saturated fat and overall dietary pattern do in most people. That said, if you are managing lipids under a physician's care, mention it at your next visit rather than assuming either way.
Can I take more than one scoop a day?
One scoop daily delivers the 2,000 mg of IgY Max that the published human work used, so a second scoop takes you past the studied amount rather than toward it. If your practitioner has a reason to run you higher for a defined period, follow their guidance. Otherwise stay at one scoop and stay consistent — consistency is doing more for you here than volume would.
Does it need refrigeration?
No. Store it sealed in a cool, dry place out of direct sunlight, and keep the scoop dry when you use it. Wet scoops introduce moisture into the tub, which is the fastest way to ruin any powder. Heat is the thing to avoid, so do not leave it in a hot car or above the stove.
How long before I decide whether it is working?
Give it eight weeks at minimum, because that is the length of the published protocol on this ingredient, and 90 days for a fair read. Then run the honest test: stop for two weeks and see whether you notice its absence. That tells you more than any product page can, including this one.
Two ingredients you can verify. One of them at the dose it was studied at.
You have a gut lining that decides what enters your body, and an immune system built around it that most supplements talk about without ever telling you how much of anything they contain. Gut RestoreX is the version of this product I wanted to exist: the primary active at 2,000 mg, the fiber disclosed honestly at 800 mg, nothing else in the scoop, and a full two months in the bottle. You will not have to wonder what you are taking. That is the whole idea.
It's Only Halftime.
