Dr. Caroline Leaf Podcast

Brain fog, anxiety, and mental decline are often treated like inevitable parts of aging. But what if that narrative is wrong? In this episode, I’m joined by Harvard-trained physician and NAD expert Dr. Andrew Salzman, Chief Medical Officer at Wonderfeel, to explore the science of brain aging—and why your brain’s “fuel supply” matters more than you think. We’ll unpack: ✅ Why cognitive decline isn’t inevitable ✅ How one molecule (NAD+) drives 500+ critical cellular functions ✅ Why NAD levels plunge by 50% by midlife—and what that means for brain health ✅ The surprising role of CD38 in accelerating aging ✅ Real-life benefits of NMN supplementation for energy, focus, and recovery ✅ How the Wonderfeel Youngr™ NMN formula is designed to protect NAD and support healthy aging This conversation is about proactive longevity—not just adding years to life, but life to your years. Whether you’re 25 or 65, your brain needs energy to thrive.
