3/31/20261 hr 24 min
Today, I'm joined by David Roberts and Dr. John Gildea, two passionate researchers whose work sits at the cutting edge of environmental health and longevity science. In this episode, we dive deep into the catalyst for developing a stabilized sulforaphane supplement—something born out of both necessity and relentless curiosity. David opens up about how environmental toxicity stopped being theoretical for him, and Dr. Gildea brings a wealth of clinical insight into why supporting our detox pathways could be a game-changer for chronic disease prevention.
