#379: The NEW Biohacking Stack For Gut Healing and Lifelong Vitality | Kiran Krishnan & Forrest Smith

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. • Visit Justthrivehealth.com/discount/NAT and use code NAT20 for 20% off sitewide. • Visit https://kineon.io/NATNIDDAM for 10% off!
