Complete Gut Restoration System

One daily scoop delivers triple-action support for your entire digestive system -

 replenishing lost bacteria, defending against harmful invaders and

 rebuilding your damaged gut lining.

01. Flora Restoration

--- PREBIOTIC OLIGOSACCHARIDES

Selectively feeds and nurtures beneficial bacteria like Bifidobacterium and Lactobacillus, helping them repopulate the gut ecosystem that antibiotics wiped out. 

02. Microbial Balance

--- LACTOFERRIN

Binds free iron in the gut environment — starving harmful bacteria and disrupting the protective biofilms they hide behind, while simultaneously promoting the growth of beneficial strains. 

03. Immune Defense

--- IMMUNOGLOBULINS (IgG)

Provides a protective shield by binding to and helping neutralize harmful bacteria, toxins, and allergens throughout the digestive tract.

04. Barrier Repair

--- PEPTIDE GROWTH FACTORS (IGF-1 · TGF-β)

Supports intestinal cells in knitting back together and restoring tight junction function — effectively sealing the microscopic gaps that allow toxins and food particles to leak into the bloodstream

Complete Upper Digestive Tract Support

One serving delivers targeted support for your entire upper digestive system stopping heartburn, soothing throat irritation, and rebuilding damaged esophageal tissue for complete repair.

--- ZINC-L-CARNOSINE • DGL • SLIPPERY ELM

Provides essential building blocks that damaged cells need to regenerate throughout your entire upper digestive tract from throat to esophagus. Supports cellular renewal at every level.

--- SODIUM ALGINATE • HYALURONIC ACID • CHONDROITIN

Creates multiple protective barriers that physically block acid from reaching and damaging sensitive tissue in your throat, esophagus, and upper digestive tract.

--- MARSHMALLOW ROOT • SLIPPERY ELM • ALOE VERA

Natural mucilage compounds coat and calm irritated tissue throughout the entire pathway from throat to stomach, providing instant comfort and lasting protection.

--- VITAMIN D3 • QUERCETIN • ALOE VERA

Targets the chronic inflammation that drives tissue damage, prevents supporting, and causes ongoing symptoms throughout your entire upper digestive system.

--- DGL LICORICE • HYALURONIC ACID • L-GLUTAMINE

Rebuilds and strengthens the protective mucus layer that shields your entire digestive tract from acid, bacteria, and irritants while supporting healthy tissue.

--- ADVANCED NANO TECHNOLOGY

Delivers supporting compounds directly where damage occurs coating throat, esophagus, and upper digestive tract as you drink. Nano particles absorb up to 98% versus 15-30% for standard pills.

What Our Customers Say

My doctor had no answers. This did.

“Three years of telling my GI doctor something was wrong and being handed a fiber supplement. Found out about colostrum on my own. The difference in my digestion inside of 30 days was more than anything a prescription ever did for me.”

- Samantha S. 

Verified Buyer

I have my life back

“Finally my constipation saga is over. ”

- Jennifer D. 

Verified Buyer

I stopped dreading meals

“I've had gut issues since my C-section antibiotics four years ago. Never connected it until I found Seelev. I'm not running to the bathroom after every meal anymore and the bloating that made me look six months pregnant is basically gone..”

- Michelle B. 

Verified Buyer

Finally something that actually works

“After two rounds of antibiotics last year my gut was completely destroyed. Bloating, loose stools, cramping every morning. I tried every probiotic on the market and nothing stuck. Two weeks on Seelev and the cramping stopped. By week four I felt like myself again.”

The Hidden Danger: The Antibiotic-Wrecked Gut No One Warns You About

Your gut was a thriving ecosystem — trillions of beneficial bacteria working together to digest food, regulate your immune system, and protect your intestinal lining. Then antibiotics carpet-bombed everything. The medication did its job against the infection, but it also destroyed the good bacteria that kept you healthy. Some beneficial species may remain depleted for years — one study found key bacteria were still suppressed two years after a single antibiotic course

The Root Cause: Antibiotics create a one-two punch — they wipe out your protective gut flora (dysbiosis) AND damage your intestinal lining (increased permeability). Scientific reviews confirm that antibiotic-induced dysbiosis "intensifies gut disorders by increasing intestinal permeability."⁸ This creates a vicious cycle of inflammation, immune dysfunction, and re-injury that progressively worsens over time.

The Hidden Danger: Chronic Esophageal Inflammation

Your esophagus is under constant attack. Every time you eat, drink, or even sleep, acidic stomach contents can splash back up, creating a cycle of inflammation that most people ignore until it's too late. This isn't just "heartburn". It's progressive tissue damage that can fundamentally change your quality of life.

The Root Cause: Damaged esophageal mucosa loses its protective barrier function, creating a vicious cycle of inflammation, supporting, and re-injury that progressively worsens over time.

What Happens When Post-Antibiotic Gut Damage Goes Unaddressed

Chronic Digestive Distress

Unresolved dysbiosis locks the gut into a cycle of unpredictable bowel swings — from urgent diarrhea to days of constipation. Without rebalancing, these symptoms become a permanent fixture, leading to social withdrawal and shrinking quality of life

Opportunistic Infections

Damaging the body's natural defense against harmful overgrowth creates ideal conditions for dangerous infections like Clostridioides difficile and SIBO, potentially requiring hospitalization or repeat antibiotic courses that deepen the damage.

Autoimmune Conditions

A compromised gut barrier allows bacterial toxins and undigested food particles to leak into the bloodstream which increases risk of autoimmune conditions including Crohn's disease and ulcerative colitis, with risk escalating with each additional antibiotic course.

Nutrient Absorption

Research links extensive antibiotic-induced dysbiosis to higher risks of metabolic syndrome, unexplained weight changes, and even increased colorectal cancer risk.¹¹

Worsening Food Intolerances

A permeable intestinal lining exposes the immune system to food particles it was never meant to encounter, triggering reactions to foods that were once perfectly safe. This expanding sensitivity turns every meal into a minefield, leading to nutritional restriction and fear of eating.

Mental Health Decline

The gut produces approximately 95% of the body's serotonin. Dysbiosis disrupts this gut-brain communication, contributing to anxiety, depression, brain fog, and crushing fatigue — symptoms that compound the physical suffering and often lead to misdiagnosis as a psychiatric condition.

What Happens When You Ignore Esophageal Health

Cell damage

Chronic acid exposure causes normal esophageal cells to transform into stomach-like cells. This abnormal condition increases the risk of life-threatening esophageal disease by 30-40x.

Strictures & Narrowing

Repeated inflammation creates scar tissue that narrows the esophagus, making swallowing painful and potentially requiring surgical intervention.

Cardiac Complications

Severe reflux can trigger irregular heartbeats, chest pain, and even severe heart symptoms, leading to emergency room visits.

Respiratory Issues

Acid reaching the lungs causes chronic cough, asthma-like symptoms, and recurrent lung complications that don't respond to typical treatments.

Sleep Disruption

Nighttime reflux destroys sleep quality, leading to chronic fatigue, depressive states, and weakened immune function.

Dental Erosion

Stomach acid reaching the mouth permanently damages tooth enamel, leading to cavities, sensitivity, and expensive dental work.

Why Colostrum Succeeds Where Probiotics Alone Fail

Standard probiotics fail because they drop a handful of bacterial strains into a damaged gut with no stable lining to anchor to — they pass straight through without rebuilding anything.

 

Seelev's Colostrum delivers four bioactive compounds simultaneously — prebiotic oligosaccharides, lactoferrin, immunoglobulins (IgG), and peptide growth factors (IGF-1, TGF-β). These compounds work together to restore beneficial flora, rebalance microbial terrain, neutralize harmful bacteria, and physically repair the damaged intestinal lining all at once.

 

The result? A rebuilt gut ecosystem — not partial relief from a single-action supplement, but complete restoration across all four layers of post-antibiotic damage. That's why most people report meaningful improvement within the first 30 days, not months of guessing.

Why Nano Technology Changes Everything

Standard esophageal supplements fail because their particles are too large to penetrate damaged tissue.

EsoRepair uses nano technology to create particles Up to 1,000 times smaller than standard supplements. These ultra-fine nanoparticles encapsulate our supporting ingredients Marshmallow Root, DGL, Slippery Elm protecting them from stomach acid degradation while driving them directly into damaged esophageal cells.

The result? Up to 10x better absorption at the cellular level where true supporting occurs. That's why users feel soothing relief from their very first dose not weeks later.

The Formulation

Dosage per serving size, made with only 12 active ingredients, essential for esophageal supporting & protection

Zinc-L-Carnosine

75 mg

When zinc is low, wounds heal about 30 percent slower. Replacing zinc brings supporting back to normal speed (9).

 

Zinc-L-Carnosine duo sticks to sore spots and speeds recovery. In a hospital study it cut tough throat damage by 60 percent compared with standard care (10).

 

Out of 75mg 16mg is Zinc and 59 mg is Carnosine.

DGL Extract

90mg

Licorice extract boosts mucus and shields tissue. A 28-day trial showed it eased reflux symptoms and improved comfort compared to baseline [19].

Slippery Elm Bark Mucilage

40 mg

About 45 percent of the bark is slick mucilage that clings to sore tissue, creating a gentle shield while you heal (16).

Aloe Vera 200:1

4.5 mg solids (≈ 900 mg fresh)

Concentrated aloe calms burning and helps cells regrow. A pilot trial showed it cut overall reflux symptoms by 55 percent, matching a prescription acid blocker (14).

Hyaluronic Acid

22.5 mg HA

These natural gels coat and calm the food pipe. Combined with usual meds they eased reflux symptoms in 53 percent of people versus 32 percent on meds alone after two weeks (12).

Marshmallow Root 10:1

22.5 mg (≈ 225 mg raw herb)

The plant’s thick mucilage forms a soothing blanket. Ninety percent of users felt relief within ten minutes in real-world surveys (13).

Chondroitin Sulfate

90 mg

Forms a soothing barrier on the esophagus. In studies with hyaluronic acid, 50 percent of users had complete relief vs 10 percent on placebo after 2 weeks [20].

Sodium Alginate

11.25 mg

Alginate turns stomach acid into a gentle “raft” that floats on top of food. Trials show it ended heartburn 4.4 times more often than placebo (11).

L-Glutamine

45 mg

Glutamine is fuel for the cells lining the gut. Supplement studies show it tightens the barrier, lowering a “leakiness” score by 0.01 units, a meaningful drop (17).

Vitamin D3

50 mcg

Vitamin D3 cools swelling in the esophagus. Research shows it can cut three major inflammation signals, IL-1β, IL-6, and IL-8, by up to 58 percent in irritated tissue (8).

Quercetin

22.5 mg

This plant antioxidant protects against acid damage. Lab work found it slashed a tissue-breaking enzyme, MMP-9, by up to 65 percent (18).

The Formulation

Dosage per serving size, made with only 7 active ingredients, essential for post-antibiotic gut restoration & repair.

Bovine Colostrum Powder (grass-fed)             5000 mg

The golden first-milk produced in the first 48 hours after birth, containing the highest concentration of bioactive compounds. Grass-fed sourcing ensures a clean, hormone-free nutrient profile. 

 

In a placebo-controlled trial, bovine colostrum supplementation reduced exercise-induced gut permeability by 80 percent (1). 

 

A 2024 meta-analysis of 10 randomized clinical trials confirmed colostrum significantly reduced intestinal permeability markers across multiple populations (9).

IgG Immunoglobulins                                             Naturally occurring

The primary antibody found in bovine colostrum, present at concentrations exceeding 30 percent of total protein.

 

A comprehensive review in Frontiers in Nutrition confirmed bovine IgG can bind to many human pathogens and limit gastrointestinal inflammation (7).

Lactoferrin                                                                  Naturally occurring

An iron-binding glycoprotein with dual action — it starves harmful bacteria by removing the free iron they need to thrive, while simultaneously promoting the growth of beneficial strains like Bifidobacterium and Lactobacillus. 

 

Research confirms lactoferrin possesses both iron-dependent bacteriostatic and iron-independent bactericidal activity, and disrupts protective biofilm structures that harmful microbes hide behind (6)

Growth Factors (IGF-1, TGF-β)                           Naturally occurring

Peptide growth factors that support intestinal cell regeneration and tight junction repair — effectively sealing the microscopic gaps in a damaged gut wall. 

 

In experimental models, colostrum growth factors reduced mucosal tissue injury by 60 percent compared with standard care (3). 

 

A 2023 study confirmed colostrum upregulates barrier-related gene expression in zonulin transgenic mice (13).

Hyaluronic Acid                                                        Naturally occurring

A naturally present glycosaminoglycan in colostrum that supports mucosal hydration and tissue repair throughout the digestive tract. Hyaluronic acid helps maintain the protective mucus layer that shields intestinal cells from irritants, supporting a healthier environment for gut barrier recovery.

Proline-Rich Polypeptides                                   Naturally occurring

Immune-modulating peptides that help the immune system distinguish between real threats and false alarms, reducing the inflammatory cascade that drives food intolerances and systemic symptoms after antibiotic-induced dysbiosis.

Oligosaccharides                                                    Naturally occurring

Forms a soothing barrier on the esophagus. In studies with hyaluronic acid, 50 percent of users had complete relief vs 10 percent on placebo after 2 weeks [20].
