Today, I'm sitting down with two true pioneers in the health optimization space: microbiologist Kiran Krishnan from Just Thrive, and Forrest Smith, founder of Kineon. In this episode, we bridge two often separate worlds—gut health and photobiomodulation—to explore what happens when you combine spore-based probiotics with red and near-infrared light therapy. You'll hear about the unexpected links between the gut and brain, the pivotal role of leaky gut in everything from neurodegeneration to hormone imbalance, and why Forrest started experimenting with shining red light directly on his abdomen.

Whether you're looking to optimize your longevity, support immunity, or simply understand how foundational gut health really is, this conversation is packed with practical strategies, cutting-edge insights, and a fresh perspective on the interconnectedness of our bodies.

Today, I'm diving solo into a topic that's both fascinating and a little bit spooky—senescent cells, also known as "zombie cells." Understanding zombie cells is a crucial piece of the puzzle if you want to feel younger, stronger, and more resilient as you age.

In this episode, I unpack what senescent cells are, why they're not just harmless bystanders, and how their buildup can accelerate the aging process and drive chronic inflammation—one of the hallmarks of aging. I break down the lifestyle habits that might be quietly increasing your zombie cell load, the early warning signs your body could be giving you, and most importantly, the evidence-backed interventions you can start using right now—from exercise and diet, to cutting-edge supplements, peptides, and more.
