Your Immune System Is Aging Faster Than You Are
Pushing The Limits
Your Immune Age Is Lying To You. Here's How To Read Your Blood And Fix It. How old is your immune system, really? It's probably not the same age as you are — and that gap may be the single biggest hidden driver of how well you age, how fast you recover, and how long you stay healthy. In this episode I break down what actually happens to your immune system as the years tick over — immunosenescence (the immune system getting weaker) and inflammaging (the silent, smouldering inflammation that never switches off) — and why almost every disease of ageing sits somewhere on that spectrum. Then...

Professor Julia Rucklidge: Micronutrients, Mental Health and Why the RDAs Are Broken
Pushing The Limits
The link between micronutrients and mental health is one of the most overlooked stories in modern medicine, and Professor Julia Rucklidge has spent more than two decades proving it matters. In this episode of Pushing the Limits, she shares the research on micronutrients and mental health that has challenged psychiatry's drug-first model, showing that broad-spectrum vitamins and minerals can treat ADHD, depression and anxiety, often as effectively as medication and without the side effects. If you have ever wondered how deeply micronutrients and mental health are connected, this conversation...

R3HBG: The Bioidentical Ketone That Bypasses the Liver | Mike Chesne, Tecton Founder
Pushing The Limits
What if there was an exogenous ketone that didn't go through the liver, didn't cause the GI distress of other ketones, and delivered bioidentical BHB directly to your cells? In this episode, Lisa sits down with Mike Chesne, founder of Tecton and retired US Army Special Forces combat medic, who spent 25 years in special operations before developing R3HBG — a patented ketone molecule that's categorically different from everything else on the market. Mike's journey from battlefield medicine to biotech is extraordinary. After suffering multiple traumatic brain injuries from IED blasts during...

INUSpheresis: Removing Toxins, Heavy Metals & Microplastics From Blood/ Tash Simons
Pushing The Limits
What if the reason you're not getting better isn't about what you're putting in — but what you can't get out? In this episode I sit down with Tash Simons from INUSpheresis Perth — the first clinic in Australia and the Southern Hemisphere to offer this advanced blood filtration therapy. We go deep into how double filtration plasmapheresis works, the two specialised filters (TKM58 and INUS 30), and the science behind removing autoantibodies, inflammatory cytokines, heavy metals, microplastics, PCBs, and oxidised LDL directly from your blood — without involving your kidneys or liver. We...

Copper, Mitochondria Grey Hair & Autism: The Missing Link No One Is Talking About
Pushing The Limits
Could a simple mineral deficiency be driving mitochondrial dysfunction in autism? In this episode I sit down with Melissa Atchley from MitoSynergy to hear her personal story of using BioCopper1 with her son on the autism spectrum — and the changes she saw that no one expected. I break down the science behind it: Dr Richard Frye's research showing Complex IV dysfunction in children with ASD, the brand new April 2026 Science Advances paper linking copper deficiency directly to ASD-like behaviours through mitochondrial damage and impaired myelination, and why the type of copper matters — Cu1+...

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