The One System Behind ALL 14 Hallmarks of Aging — And How to Target It | Courtney Van Bussum

Your immune system isn't just fighting off colds. It's the foundational system that influences all 14 hallmarks of aging — and when it declines, everything downstream accelerates.

In this episode, I sit down with Courtney Van Bussum, COO of Longevity Launch Labs, to dive deep into immunosenescence — the aging of the immune system — and why it starts far earlier than most people realise. We unpack what Stanford's landmark 1000 Immunomes Project revealed about the real driver of biological aging, why your supplement stack might be missing the most important piece, and how we built Re:juvenate Pro (Cell Restore in the US) to target immune aging at its root.

We get into the fire station analogy that makes the immune system finally make sense, why 70-80% of your immune system lives in your gut and what that means for barrier health, the science behind four synergistic ingredients — Immune Defense Protein, Immunel colostrum extract, carnosic acid from NZ rosemary, and kawakawa — and why standard colostrum supplements aren't cutting it.

We also cover why NSAIDs are impairing your recovery, what CXCL9 is and why most practitioners have never heard of it, Isobel's lymphocyte count recovery story, the immune age calculator app, and why "boost your immune system" is the wrong approach — modulation is everything.

This is not another colostrum product. This is upstream immune intervention.
