Welcome to Core Immune Health


At Core Immune Health, our mission is simple: to offer a small, carefully curated selection of high-potency natural products—and to serve as a reliable source of information on some of the most promising natural health interventions available today.

We focus on quality, not quantity. Rather than stocking dozens of products, we offer only a select few—each chosen for its clinical relevance, scientific backing, and therapeutic potential. Our flagship offerings center around PSK (Polysaccharide-K) and PSP (Polysaccharopeptide)—two powerful extracts from the Coriolus versicolor mushroom, extensively studied for their immune-modulating and cancer-supportive properties.

Our Core Product Line

  • PSK – A highly standardized immune-support compound used for decades in Japan alongside chemotherapy. Known to activate T-cells, NK cells, and macrophages.
  • PSP – Offers similar immune benefits to PSK with additional anti-inflammatory and gut-modulating effects. Being explored for a range of applications from hormonal balance to neuroinflammation.
  • PSK/PSP Blend – A 70/30 clinical-grade combination, providing complementary immune and systemic support.

These are not everyday supplements. They are research-backed extracts, designed for those seeking targeted immune support, often in the context of complex or chronic health conditions.

More Than a Supplement Store

While we sell only a few products, our broader aim is to educate and inform. We understand that many people today are seeking alternatives to conventional treatments—whether that means medicinal mushrooms, repurposed pharmaceuticals, or other natural compounds with emerging evidence.

That’s why we maintain a growing blog and video library, where we explore:

  • The science behind PSK and PSP—how they work, what the studies show, and what that means for real-world use
  • Health conditions such as prostate cancer, PMDD, fibrocystic breast disease, and immune dysregulation
  • Comparisons of natural compounds and insights into dosage, sourcing, and safety
  • Discussions on repurposed drugs and off-label options gaining interest in functional and integrative medicine circles

Why People Trust Core Immune Health

  • Focused, high-quality products—We do not flood the shelves with trends. We only sell what meets rigorous standards for clinical relevance and purity.
  • Evidence-based information—Our content is grounded in published research, case studies, and traditional use cases.
  • Educational transparency—We believe people should be informed about all of their options, and we aim to be a trusted resource in that process.
  • Support for both patients and practitioners—Whether you're exploring options yourself or supporting someone through a diagnosis, we aim to provide clear, credible guidance.
