LONGEVITY with Nathalie Niddam

📍 Good news! My original Instagram is back! Please follow my original account at https://www.instagram.com/nathalieniddam/ and also my backup account at https://www.instagram.com/longevitywithnat/.

Today, I’m joined by the innovative Garrett Salpeter, an engineer-turned-neuroscience trailblazer and the founder of NeuFit. In this episode, Garrett Salpeter reveals how a college hockey injury—and a near miss with surgery—catapulted him into the world of neurology and direct current stimulation. His personal story of healing, curiosity, and relentless pursuit of understanding the nervous system will change how you think about pain, movement, and recovery.

Today, I’m joined by Dr. Rafael Gonzalez, a longtime leader in regenerative medicine whose work spans everything from spinal cord injuries to cutting-edge immune modulation and stem cell therapies. Dr. Gonzalez takes us through his journey from studying secondary degeneration in the nervous system to diving deep into what actually drives healthy aging—and what most people get wrong about immune decline, senescent cells, and the promise (and pitfalls) of regenerative interventions.

Today, I’m joined by Steve Scott, an entrepreneur, researcher, and author of The Carbonated Body, who is on a mission to change the way we think about carbon dioxide—and trust me, it’s not just a waste gas. In this episode, Steve makes a compelling case for why CO2 is vital for better energy, resilient mitochondria, and improved recovery, and explains how we’ve misunderstood its role in human health for far too long.

Together, we dive into one of the biggest topics of our time—microplastics. With fresh research showing a 74% reduction in blood microplastics in just one month, Heather Hutchens and Dr. Debra Kimless from Pure BioHealth open up about what that means for our health, our pets, and how we think about longevity.

In this eye-opening conversation, we break down how microplastics don’t just clutter our environment—they infiltrate our bodies, disrupt cellular energy, drive chronic inflammation, and even pass through to future generations. We also get real about the hidden sources of plastic exposure all around us, including the products we think are “healthy,” and why our companion animals may be the environmental sentinels we’ve been ignoring.
