Prime Gut Health

Prime Gut Health — Advanced Gut Barrier & Microbiome Support Formula

Most gut health products seed the microbiome. Prime Gut Health was built to repair the environment first.*

Adding probiotic bacteria to a compromised gut is like planting seeds in concrete — without addressing the underlying barrier dysfunction and immune imbalance that created the problem, new bacteria have little chance of establishing or thriving. Prime Gut Health takes a fundamentally different approach: addressing gut barrier integrity, immune balance, and butyrate production before and alongside microbiome reconditioning.

Four clinically studied ingredients. Four non-redundant mechanisms. One formula that works from the gut wall outward — repairing the foundation, fueling the colonocytes that maintain it, and then reconditioning the microbiome environment into one where beneficial bacteria can genuinely thrive.*

 THE FORMULA

ImmunoLin® (Serum-Derived Bovine Immunoglobulin Protein Isolate)

Role: Gut-Immune Balance, IgG-Mediated Barrier Support & Pathogen Neutralization Over 40 Published Human Studies

ImmunoLin® is serum-derived bovine immunoglobulin protein isolate (SBI) — a concentrated fraction of bovine serum proteins rich in IgG immunoglobulins. Unlike colostrum-based immunoglobulins or whey protein fractions, SBI is derived directly from bovine serum — providing a highly concentrated, stable, and bioavailable IgG source with the most extensive clinical evidence base of any immunoglobulin ingredient in the gut health space.*

With over 40 published human studies, ImmunoLin® is the most clinically documented immunoglobulin ingredient in the gut health supplement category — with evidence spanning gut barrier function, intestinal immune balance, IBS-D, HIV enteropathy, inflammatory bowel conditions, and microbiome modulation.*

How ImmunoLin® works — four distinct and validated mechanisms:*

IgG Binding and Pathogen Neutralization: SBI IgG binds conserved microbial and viral antigens — bacteria, bacterial fragments, and lipopolysaccharide (LPS) — in the gut lumen, preventing their translocation across the epithelial barrier into the bloodstream.* This mechanism directly addresses one of the primary drivers of systemic inflammation: gut-derived endotoxin leakage.*

Gut Barrier Function Support: ImmunoLin® supports tight junction protein expression and epithelial barrier integrity — the structural layer that physically separates the gut contents from the systemic circulation.* In a 2024 ex vivo human study using SIFR® technology (24 human adults), SBI promoted gut barrier integrity more profoundly than dietary protein under LPS-induced inflammatory conditions.*

GI Immune Homeostasis: SBI modulates gut-associated immune activity — supporting balanced mucosal immune responses rather than broad immune stimulation. It supports secretory IgA levels and helps maintain the immune surveillance environment of the GALT (gut-associated lymphoid tissue).*

Microbiome Modulation: Recent research demonstrates SBI partially resists digestion, reaching the colon where it specifically stimulates the production of health-promoting metabolites including indole-3-propionic acid (IPA) — a tryptophan metabolite associated with gut barrier integrity and systemic health — alongside increases in short-chain fatty acids.*

Clinical Evidence Highlights:*

• 2024 ex vivo SIFR® study (24 human adults): SBI significantly promoted gut barrier integrity and lowered inflammatory markers TNF-α and CXCL10 — outperforming dietary protein*
• Multiple human RCTs demonstrating improvement in digestive symptoms (loose stools, bloating, abdominal discomfort) in IBS-D patients*
  
• 40+ peer-reviewed human studies — the largest clinical evidence base of any gut immunoglobulin ingredient*

CoreBiome® Tributyrin

Role: Colonic Butyrate Delivery, Colonocyte Fuel & Barrier Maintenance The Most Important Short-Chain Fatty Acid — Delivered Where It Is Needed

Butyrate is the primary fuel source for colonocytes — the epithelial cells that line the colon and form the innermost layer of the gut barrier. When colonocytes have sufficient butyrate, they maintain tight junction integrity, produce mucin for the protective mucus layer, and regulate inflammatory signaling. When butyrate is deficient — as it is in dysbiotic, fiber-depleted, or post-antibiotic gut environments — barrier integrity deteriorates and inflammatory tone increases.*

The challenge with oral butyrate supplementation: conventional butyrate salts (sodium butyrate, calcium-magnesium butyrate) are absorbed in the small intestine before reaching the colon, where butyrate is most needed. They also have a strong, unpleasant odor that limits compliance.

CoreBiome® solves both problems through tributyrin — a naturally occurring triglyceride form of butyrate (three butyrate molecules esterified to a glycerol backbone) that resists upper GI absorption due to its triglyceride structure. Pancreatic lipases cleave the butyrate molecules progressively through the intestine and into the colon — delivering butyrate precisely where colonocytes need it.*

Published Evidence — CoreBiome® Tributyrin (2025 Frontiers in Nutrition):*

• Upper GI simulations confirmed 51–59% of tributyrin dose reaches the colon intact for colonic butyrate conversion*
• 3-week SHIME® model treatment increased colonic butyrate levels significantly*
• Tributyrin supplementation enhanced Bifidobacterium spp. and Akkermansia muciniphila populations — two of the most clinically significant beneficial bacteria in the gut health research literature*
• Protective effect on intestinal barrier integrity confirmed in Caco-2/THP1 co-culture cellular models*
  

Beyond barrier support, butyrate serves as an epigenetic regulator through histone deacetylase (HDAC) inhibition — supporting gene expression patterns associated with healthy colonocyte function, immune tolerance, and reduced inflammatory signaling in the gut epithelium.*

Sporebiotics (SNZ TriBac — Bacillus Coagulans SNZ 1969®, Bacillus Subtilis SNZ 1972, Bacillus Clausii SNZ 1971)
Role: Microbiome Reconditioning, Digestive Comfort & Gut Immune Modulation

The three-strain SNZ TriBac sporebiotic blend in Prime Gut Health takes a fundamentally different approach to probiotic supplementation than conventional Lactobacillus and Bifidobacterium products — through a combination of spore-based survivability, strain-specific clinical evidence, and complementary mechanisms targeting gut motility, immune modulation, and microbiome reconditioning.*

The critical difference: survivability and colonization capacity.

Conventional vegetative probiotics face a fundamental problem: the acidic stomach environment and bile exposure during upper GI transit destroys the vast majority before they reach the large intestine where they are needed. Bacillus spores operate through a bi-phasic life cycle — in harsh environments including gastric acid, bile, and temperature extremes, they enter a dormant endospore state that protects them completely through upper GI transit. Once they reach the large intestine, they germinate into their active vegetative form and begin colonizing and reconditioning the microbiome environment.*

Bacillus Coagulans SNZ 1969® — The Foundational Strain
B. coagulans SNZ 1969® was originally isolated in Japan in 1949 and is the most clinically studied strain in this blend. It is a lactic acid-producing Bacillus that is highly resistant to gastric acidity and bile acids, ensuring reliable delivery and colonization in the large intestine.*

Bacillus Subtilis SNZ 1972 — Small Intestine and Immune Modulation Support
B. subtilis SNZ 1972 is a spore-forming strain optimized to support the small intestinal microbiome environment alongside the large intestinal activity of B. coagulans and B. clausii.* B. subtilis produces a range of antimicrobial compounds and enzymes that support a balanced intestinal ecology — creating conditions that favor beneficial commensal bacteria while inhibiting pathogenic overgrowth.* SNZ 1972 is self-affirmed GRAS by Sanzyme Biologics.*

Bacillus Clausii SNZ 1971 — Antibiotic Resilience and Microbiome Restoration
B. clausii SNZ 1971 is distinguished by its notable antibiotic resistance profile — it can survive alongside antibiotic therapy, making it particularly relevant for patients during or recovering from antibiotic courses where microbiome disruption is a primary clinical concern.* B. clausii has a long history of safe use in the GI tract from pediatric through adult populations, and supports immune balance and microbiome restoration in post-antibiotic environments.*

Combined Tri-Strain Clinical Evidence:*
- A prospective, randomized, double-blind, placebo-controlled trial evaluated the SNZ TriBac combination (B. coagulans SNZ 1969 + B. clausii SNZ 1971 + B. subtilis SNZ 1972) in 60 adults with GI discomfort — demonstrating significant improvement in GI symptoms including burping/belching, bloating, and digestive discomfort scores on both SODA and GSRS scales across 30 and 37-day assessments*

AstraGin® (Astragalus membranaceus + Panax notoginseng Root Extracts)

Dose: 50 mg Role: Nutrient Transporter Upregulation & Gut Wall Integrity Support by NuLiv Science

AstraGin® is a patented botanical blend with an established research profile for supporting intestinal nutrient absorption through upregulation of key nutrient transporter proteins — including SGLT-1 (glucose/sodium), CAT1 (arginine), and PEPT1 (peptide transport) — in the intestinal wall.*

In Prime Gut Health, AstraGin® serves two roles. First, it supports the absorption of the formula's active ingredients — ensuring ImmunoLin®'s IgG fractions and tributyrin-derived butyrate are efficiently utilized. Second, it supports gut barrier integrity directly through tight junction organization and healthy inflammatory tone in the intestinal mucosa — adding a fourth structural support layer to the formula's barrier repair architecture.*

AstraGin® is also featured in Longevity, GlucoPrime™, and dailyDIM+™ — consistently serving as the absorption foundation layer in Healthgevity formulas where gut barrier integrity and ingredient bioavailability are concurrent clinical priorities.*

THE LAYERED GUT REPAIR ARCHITECTURE

Why Four Ingredients, Not One

The gut ecosystem has three distinct layers that must function together for genuine gut health:

The barrier layer — tight junctions between colonocytes that physically prevent leakage of gut contents into the bloodstream. ImmunoLin® and AstraGin® support this structurally.*

The fuel layer — butyrate availability that determines whether colonocytes have the energy to maintain barrier integrity and regulate inflammation. CoreBiome® tributyrin delivers this directly to the colon.*

The microbiome layer — the bacterial community that produces the SCFAs, immune signals, and metabolites that determine the gut's long-term functional environment. Bacillus sporebiotics recondition this from the ground up — not reseeding with fragile organisms, but establishing resilient commensals that shift the entire microbial ecology toward balance.*

Most gut supplements address one layer. Prime Gut Health addresses all three — simultaneously.
