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

What Our Customers Say

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.”

- Margaret S. 

Verified Buyer

Finally have my life back

“I suffered for years but now I have my life back.”

- Michelle D. 

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..”

- Jen B. 

Verified Buyer

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..”

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.

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.

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.

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].
