Immuno-LP20®
Mechanism of Action +
### The Immunobiotic Paradigm Traditional probiotics rely on the ingestion of live microorganisms to colonize the gastrointestinal tract and alter the local microbiome. However, Immuno-LP20® operates on a fundamentally different biochemical paradigm known as 'immunobiotics.' Immunobiotics are microbial strains that exert beneficial effects on the immune system independently of their viability. Immuno-LP20® utilizes a specific strain, Lactiplantibacillus plantarum L-137, which is deliberately heat-killed (HK L-137).
### The Heat-Killing Process and Cell Wall Integrity The efficacy of Immuno-LP20® hinges on its proprietary heat-treatment process. Live lactobacilli are susceptible to degradation by stomach acid, bile salts, and digestive enzymes, which can alter their cellular structure before they reach the lower intestine. Heat-killing the L-137 strain at the optimal phase of its growth cycle rigidifies and preserves its cellular architecture, particularly the lipoteichoic acids (LTA) and peptidoglycans embedded in the bacterial cell wall. Because the bacteria are non-viable, they do not metabolize or degrade during transit, allowing the intact cell wall components to reach the small intestine in a highly concentrated, structurally pristine state.
### Interaction with Gut-Associated Lymphoid Tissue (GALT) Upon reaching the small intestine, the preserved cell wall components of HK L-137 interact directly with the Gut-Associated Lymphoid Tissue (GALT), specifically the Peyer's patches. Microfold (M) cells located in the epithelium overlying the Peyer's patches transport the HK L-137 particles from the intestinal lumen to underlying antigen-presenting cells, such as dendritic cells and macrophages.
### Toll-Like Receptor (TLR) Activation and IL-12 Induction The lipoteichoic acids of HK L-137 are recognized by pattern recognition receptors, primarily Toll-like receptor 2 (TLR2), on the surface of these macrophages and dendritic cells. This binding triggers an intracellular signaling cascade via the MyD88 pathway, culminating in the activation of NF-κB and the subsequent transcription and robust secretion of Interleukin-12 (IL-12).
### Th1 Immune Shift and Systemic Defense IL-12 is a master regulatory cytokine that drives the differentiation of naive T cells into T helper 1 (Th1) cells. A Th1-dominant immune response is critical for cell-mediated immunity, enhancing the phagocytic activity of macrophages and the cytotoxic capabilities of Natural Killer (NK) cells and cytotoxic T lymphocytes. By upregulating IL-12, Immuno-LP20® effectively primes the innate immune system to respond more rapidly and aggressively to viral and bacterial pathogens, which explains its clinical efficacy in reducing the incidence and duration of upper respiratory tract infections (URTIs). Furthermore, this immune modulation exerts systemic anti-inflammatory effects, contributing to improvements in periodontal health and the acceleration of hyaluronic acid production in the skin.

Everything About Immuno-LP20® Article
## Introduction to Immuno-LP20®
In the rapidly evolving landscape of dietary supplements, the conversation around gut health and immunity has largely been dominated by traditional probiotics—live bacteria intended to colonize the digestive tract. However, a groundbreaking paradigm shift has emerged with the development of **immunobiotics**. Leading this charge is **Immuno-LP20®**, a proprietary, heat-killed strain of *Lactiplantibacillus plantarum* (HK L-137) developed by House Wellness Foods.
Originally isolated from *narezushi*—an ancient, traditional fermented sushi from Southeast Asia—this specific bacterial strain has been utilized for centuries for its health-preserving properties. Today, rigorous scientific scrutiny has transformed this ancient wisdom into a highly stable, clinically validated functional food ingredient designed to support immunity, respiratory health, oral health, and even skin vitality.
## The Immunobiotic Advantage: Why Heat-Killed is Better
The most common question surrounding Immuno-LP20® is: *"If the bacteria are dead, how can they be beneficial?"*
To understand this, we must differentiate between a **probiotic** and an **immunobiotic**. Probiotics rely on live microorganisms surviving the harsh, acidic environment of the stomach to reach the intestines, where they attempt to colonize and alter the local microbiome. This process is highly inefficient; many live strains die during transit, and those that survive often fail to establish a permanent presence.
Immuno-LP20® takes a completely different approach. The *L. plantarum* L-137 strain is intentionally subjected to a precise heat-treatment process at the peak of its growth phase. This heat-killing process (creating HK L-137) does not destroy the bacteria; rather, it rigidifies and preserves the structural integrity of the bacterial cell wall.
Because the bacteria are non-viable, they are completely unaffected by digestive juices, stomach acid, or bile salts. Furthermore, they are incredibly stable at room temperature, requiring no refrigeration and boasting an extended shelf life. When these intact, heat-killed cell walls reach the small intestine, they are recognized by the body's immune sensors with maximum bioavailability.
## Mechanism of Action: Modulating the Immune System
The true power of Immuno-LP20® lies in its interaction with the Gut-Associated Lymphoid Tissue (GALT). The GALT contains roughly 70% of the body's immune cells. When the preserved cell walls of HK L-137 pass through the small intestine, they are taken up by M-cells in the Peyer's patches and presented to immune cells like macrophages and dendritic cells.
The lipoteichoic acids on the surface of HK L-137 bind to Toll-like receptors (specifically TLR2) on these immune cells. This binding acts as a powerful signal, triggering the robust production of **Interleukin-12 (IL-12)**. IL-12 is a critical cytokine that shifts the immune system toward a **Th1 response**, which is responsible for defending the body against intracellular pathogens like viruses. By inducing IL-12, Immuno-LP20® effectively "wakes up" the innate immune system, enhancing the activity of Natural Killer (NK) cells and cytotoxic T-cells.
## Four Pillars of Clinical Efficacy
According to clinical data and expert analysis from researchers like Dr. Michael Murray, Immuno-LP20® supports human health across four distinct fronts:
### 1. Respiratory Health and URTI Prevention Upper Respiratory Tract Infections (URTIs), including the common cold, are a primary reason consumers seek immune support. Clinical trials have demonstrated that daily supplementation with Immuno-LP20® significantly reduces both the incidence and duration of URTIs. By maintaining a primed Th1 immune response, the body is better equipped to identify and neutralize respiratory viruses before they can establish a severe infection.
### 2. Oral Health and Periodontal Support Periodontal disease is characterized by chronic inflammation of the gums, leading to the deepening of periodontal pockets. The systemic anti-inflammatory effects of HK L-137 have been shown to ameliorate periodontal pocket depth. By balancing the immune response, Immuno-LP20® helps mitigate the destructive inflammation triggered by oral pathogens.
### 3. Skin Health and Hyaluronic Acid Production The gut-skin axis is a well-documented physiological pathway. Interestingly, clinical studies on Immuno-LP20® have revealed that its immune-modulating effects accelerate the endogenous production of hyaluronic acid. Hyaluronic acid is a vital molecule for skin hydration, elasticity, and tissue repair, making Immuno-LP20® a unique "beauty-from-within" ingredient.
### 4. Digestive Health and Inflammatory Bowel Conditions While it does not colonize the gut like a traditional probiotic, the immune-balancing effects of *Lactiplantibacillus plantarum* are well-documented by authorities like WebMD. It is frequently used to help manage symptoms of Irritable Bowel Syndrome (IBS) and ulcerative colitis. By downregulating excessive Th2-driven inflammation in the gut lining, Immuno-LP20® helps maintain intestinal barrier integrity.
## Dosing and Formulation
Immuno-LP20® is typically formulated as a powder containing 20% active HK L-137 and 80% dextrin (a carrier). The clinically studied and recommended dose of the Immuno-LP20® complex is **50mg per day**, which yields 10mg of the active heat-killed bacteria. Because of its extreme stability, it can be easily incorporated into capsules, tablets, powders, and even functional foods and beverages without losing efficacy.
## Safety and Tolerability
Immuno-LP20® has held Generally Recognized As Safe (GRAS) status in the United States since 2009. It has been used safely by millions of consumers. Because the bacteria are non-viable, there is zero risk of bacterial translocation or opportunistic infection, which is a rare but potential risk with live probiotics in severely immunocompromised individuals. However, as with any supplement that modulates the immune system, individuals on immunosuppressive medications should consult their healthcare provider before use.
## Conclusion
Immuno-LP20® represents the next evolution in microbiome science. By moving past the limitations of live probiotics and harnessing the power of heat-killed immunobiotics, House Wellness Foods has created an ingredient that offers unparalleled stability, bioavailability, and clinical efficacy. Whether you are looking to ward off seasonal colds, improve your gum health, or support your skin, Immuno-LP20® provides a scientifically rigorous, multi-faceted approach to systemic wellness.
