You can stack every biohack imaginable—but without the right people in your life, your progress will eventually stall. As the founder of the Health Optimisation Summit, Tim Gray gets that. He’s built a global ecosystem around one simple idea: community is the fourth pillar of longevity. Tim joins me on the podcast for the fifth time (yes—fifth) to explore some of the latest breakthroughs in wellness, performance, and human connection: -How vagus nerve stimulation, cold plasma therapy, and the “Human Regenerator” might reshape recovery protocols -What Tim used to recover from chronic sinus infections—including IP6 (a powerful antioxidant), targeted iron strategies, and post-surgery immune support -What stem cell eye drops and exosome tech are doing for inflammation, healing, and ocular performance -Why mimicking nature often beats chasing the next device, and what today’s top “biohacks” are really trying to recreate You’ll also get a behind-the-scenes look at what’s coming to the Health Optimisation Summit London this September—everything from next-gen food brands and ethical oils to tools that support full-spectrum optimization from the inside out. I’ll also be back on stage in London, alongside top minds in biohacking, nutrition, mental performance, and functional health. It’s not just an expo—it’s a hands-on environment for learning, testing, and connecting with people who take their health seriously.
