Comprehensive Pre/Pro/Post Biotic Formula*

  • OVERVIEW

    GI Prime is a dietary supplement formulated to support gut health and promote overall digestive well-being. This advanced blend combines the following ingredients known for their beneficial effects on gut microbiota and immune function: Epicor® , which has been shown to support gut health by promoting a balanced gut microbiota, modulating immune function, and optimizing gut barrier integrity. IMMUSETM , a cutting-edge postbiotic, has been clinically shown to aid the body's natural defenses at the cellular level to provide comprehensive gut and immune support year-round. ButyragenTM serves as a prebiotic, butyrate-producing innovation. All of these well researched, branded ingredients are combined with a 12 billion CFU blend of Bacillus coagulans, subtilis, and clausii.

  • INGREDIENTS

    EpiCor®

    EpiCor® is a postbiotic, a term which when broken down means ‘after’ and ‘life’. The term postbiotic appropriately refers to substances derived after the microorganisms are no longer alive, or, in other words, inanimate, dead or inactivated but still confer a health benefit. EpiCor® is a whole food fermentate made using yeast (“Saccharomyces cerevisiae”) that goes through a closely held trade secret fermentation and drying processes. This fermentation process makes a unique fingerprint of metabolites including proteins, polyphenols, vitamins, minerals, amino acids, polysaccharides, fiber, and other nutrients.


    Over a dozen published studies show EpiCor® postbiotic helps to support your immune system and modulate the gut microbiota. The direct role it has on gut health relies on two main mechanisms of action. First, the modulation of gut microbiota: Epicor® promotes a balanced gut microbiota by supporting the growth of beneficial bacteria, such as Lactobacillus and Bifidobacterium species, while inhibiting the growth of potentially harmful bacteria. This modulation helps maintain a healthy microbial balance, which is essential for optimal digestion, nutrient absorption, and overall gut health. Second, is through supporting gut barrier integrity: Epicor® supports the integrity and function of the gut barrier, which acts as the primary protective barrier between the gut lumen (the inner space of the intestines) and the rest of the body. It prevents the translocation of harmful substances, such as toxins and bacteria, into the bloodstream. By strengthening the gut barrier, Epicor® aids in ensuring minimal amount of gut permeability and helps maintain an overall healthy gut ecosystem.1,2


    IMMUSETM

    IMMUSETM is a novel postbiotic, specifically targeting the immune system. The primary benefit of IMMUSETM (Lactococcus lactis JCM 5805) is its ability to promote pDC, which are a rare subset of immune cells that have been described as the commander-in-chief or leader of the immune system. It's been well established that pDC’s themselves activate natural killer cells, killer T cells, helper T cells and B cells. In short, this postbiotic provides comprehensive immune support and is backed by 30 published studies, 15 of which are human trials.3,4 In addition to IMMUSETM's clinical successes, it’s been awarded the Product of the Y ear by NutraIngredients-Asia, as well as being bestowed the North American Immune Health Ingredient New Product Innovation Award. Both of these honors further validate the strength of this ingredient as a groundbreaking postbiotic.


    ButyraGenTM

    ButyraGenTM is an innovative next-generation prebiotic – its primary function is as a direct butyrate generator that lends to gut health and beyond, generating high levels of butyrate directly in the colon. This is what sets it apart from traditional prebiotics: its unique ability to generate butyrate mostly independent of the state of the microbiome. In other words, the microbiome doesn’t have to be fully balanced and in its most optimal state in order for butyrate to be made.

    Other prebiotics work solely by feeding bacteria that then generate butyrate and are completely dependent on the state of the microbiome. ButyraGenTM, which only requires 200 mg, can be especially effective when combined with probiotics to further promote the health benefits of the probiotic strains. When consumed, ButyraGenTM is broken down into butyrate, which serves as a primary energy source for the cells lining the intestinal tract. Butyrate supports the integrity of the gut barrier. This helps prevent the translocation of harmful substances and toxins, maintaining gut health and optimal digestion.5,6


    Additionally, butyrate aids in optimizing digestion and nutrient absorption. But the impact is not limited to the digestive system alone. The gut-brain axis is influenced by butyrate production in the gut as well. Butyrate acts as a signaling molecule, communicating with the central nervous system and influencing brain function. By supporting butyrate production, ButyraGenTM indirectly contributes to a balanced gut-brain axis, potentially impacting cognitive function, mood, and mental well-being.


    Bacillus Strains of Probiotics

    The probiotic strains Bacillus coagulans, Bacillus subtilis, and Bacillus clausii, found in GI Prime, can potentially influence the gut-brain axis. The gut-brain axis refers to the bidirectional communication pathway between the gut and the brain, involving the nervous, endocrine, and immune systems.

  • Why is maintaining a healthy gut so important?

    Your gut plays a central role in overall wellness. Also known as the GI tract, it is home to trillions of beneficial bacteria that help maintain digestion, nutrient absorption, and immune balance.

    Here’s why gut health matters:

    • Regular digestion and nutrient absorption: These are foundational for sustained energy and overall wellness.
    • Balanced beneficial bacteria: Eating fiber-rich foods helps friendly microbes thrive, supporting a resilient gut environment.
    • Blood sugar balance and nervous system function: Both contribute to steady energy levels and balanced mood.
    • Whole-body wellness support: A well-balanced gut microbiome is associated with healthy metabolic and immune function.
    By keeping the digestive system functioning well, a healthy gut supports consistent digestion and everyday vitality.

  • How does a healthy gut impact mental well-being?

    The gut and brain are connected through what’s often referred to as the gut-brain axis, a communication network linking the digestive system and the brain. A diverse and balanced gut microbiome contributes to the production of certain neurotransmitters that influence mood, stress response, and sleep patterns.

    Here’s how gut balance supports mental well-being:

    • Neurotransmitter support: A balanced gut microbiome supports the production of compounds involved in mood and stress regulation. Emerging research suggests that supporting gut-brain communication pathways (including neurotransmitter activity, immune signaling, and metabolic processes) may contribute to a more positive mental outlook.
    • Immune system support: Lifestyle habits and dietary patterns influence gut balance. By supporting nutrient absorption and maintaining microbial diversity, a healthy gut helps the body respond to everyday stressors.
    • Nutrient utilization: A well-functioning gut helps the body efficiently absorb nutrients, supporting steady energy and overall mental clarity.
    Research in this area is ongoing and not definitive. Individual experiences may vary.
