Key Ingredients

Our formulas are made with clean, natural ingredients, with clinically-validated dosages to support health and performance.

PreforPro® Bacteriophase Prebiotic Complex

15 mg
PreforPro® is a “bacteriophage prebiotic complex” that works by targeting unwanted bacteria in the gut and helping healthy gut bacteria thrive.

IMMUSE® Lactococcus lactis Postbiotic

100 mg (>100B cells)
Heat-killed Lactococcus lactis postbiotic shown to stimulate immune function at the cellular level for system-wide immune support.

Probiotic Blend

22 Billion CFU (Colony Farming Units)
Four clinically studied strains selected for active lifestyles—supporting digestive comfort, microbiome balance, and immune health, with strain-to-strain and prebiotic synergy.

PreforPro® Bacteriophase Prebiotic Complex

15 mg

PreforPro® is a novel phage-based prebiotic containing LH01-Myoviridae, LL5-Siphoviridae, T4D-Myoviridae, and LL12-Myoviridae. Unlike common fiber-based prebiotics, it works by targeting specific unwanted bacteria, releasing nutrients that support beneficial Lactobacillus and Bifidobacterium, to help maintain a balanced gut environment. In randomized, double-blind trials in healthy adults [1,2], PreforPro® used together with Bifidobacterium lactis BL-04® (in our probiotic blend) produced signals for improved GI inflammation and reduced colon-pain scores, plus increases in beneficial bacteria, without disrupting the broader microbial community.

IMMUSE® Lactococcus lactis Postbiotic

100 mg (>100B cells)

A postbiotic is a non-live (“inanimate”) microbial preparation that still confers a health benefit—unlike probiotics, it doesn’t need to be alive to work. IMMUSE® is a heat-killed form of Lactococcus lactis strain Plasma (LC-Plasma) that activates plasmacytoid dendritic cells (pDCs) coordinating broader innate and adaptive immunity.

IMMUSE® is supported by several peer-reviewed clinical studies for its effects on immune function, recovery, and exercised-induced fatigue. In athletes under high training load, IMMUSE® increased pDC activity and reduced cumulative fatigue days under high training load. [3] Several additional studies have evaluated IMMUSE® in the context of supporting immune function and upper respiratory tract health. [4, 5

 This data demonstrates that IMMUSE® helps active individuals keep their immune system ready and functioning optimally for year-round health.

Probiotic Blend

22 Billion CFU (Colony Farming Units)

Our 22 Billion CFU Probiotic Blend was purpose-built for healthy, active adults and combines Bifidobacterium lactis BL-04®, Lacticaseibacillus acidophilus NCFM®, B. lactis Bi-07®, and B. animalis subsp. lactis B420™ to support digestive comfort, microbiome balance, and everyday immune health. Probiotics are “good bacteria” that help keep your gut ecosystem in balance, which in turn supports systemic health. We selected strains that complement each other—and that also pair with our PreforPro® phage prebiotic—to help beneficial bacteria thrive and keep your microbiome healthy. Each of these strains and their respective dosages is supported by peer-reviewed clinical studies. BL-04® was linked to a lower risk of upper-respiratory illness in active adults and showed reduced nasal inflammatory response/viral shedding. [6, 7] NCFM® showed alleviation of discomfort in those with pronounced abdominal pain. [8]; the NCFM® + Bi-07® combo can support immune function and exercise readiness in active individuals  [9]; and B420™ can improve body-composition when taken consistently [10]. Notably, PreforPro® + BL-04® together have shown improvements in GI symptoms and increases in beneficial gut bacteria in randomized controlled trials—supporting our prebiotic + probiotic design.

Frequently Asked Questions

Live microorganisms are very sensitive to damage from moisture and oxidation, and can degrade without the appropriate protection. We use only necessary excipients and flow agents to ensure that the microorganisms remain stable and protected.Our capsules are designed to support probiotic survival  through stomach acid to  safely reach the intestines, where they can deliver their full benefits.

 

Probiotics are live microorganisms that, when taken in adequate amounts, help support immune health and  healthy gut microbiome. A synbiotic contains a combination of both  a probiotic with a prebiotic—a substance that is selectively used by gut microbes to confer a benefit to the host (aka you! ). Together, they deliver validated health benefits through multiple, science-backed mechanisms.
