Every Theronomic formula follows one evidence-backed standard. We design to the Seed • Feed • Shield model with clinically-validated dosing, characterised inputs, and rigorous stability and purity testing protocols.

• Seed probiotics with defined strain IDs and CFU counts based on published clinical trial data and human microbiome research.
• Feed prebiotics that selectively nourish beneficial taxa and support short chain fatty acid production, as demonstrated in controlled studies.
• Shield postbiotics that provide stable signalling to reinforce barrier and immune function through documented mechanistic pathways.
  

Our promise is evidence-driven. Clinical research informs our formulations, third-party testing validates our labels, and ecosystem-level design guides every product decision.

Our commitment to quality starts at the source and extends through every step of production. We exclusively manufacture in New Zealand and Australia under strict Good Manufacturing Practice (GMP) standards, ensuring consistent quality and supply confidence across our entire range.

Every ingredient is purposefully selected for its role in our signature FEED • SEED • SHIELD architecture, from precision prebiotics like Livaux® Gold Kiwifruit powder to genetically sequenced, strain-specific probiotics with documented heritage. We maintain radical transparency by disclosing exact amounts, strain names, and CFU counts rather than hiding behind proprietary blends, while our independent third-party testing verifies potency, purity, and safety before any product reaches your hands.
