Why cold and flu season weakens immunity

In this episode, Dr. Jockers and Dr. Chris D'Adamo break down how your immune system learns, adapts, and strengthens over time—and why beta-glucan is one of the most researched natural compounds for resilience. You'll hear how immune modulation, not just stimulation, can keep you healthy through stress, seasonal shifts, and everyday exposures.

You'll learn how gut health, stress hormones, and immune function are deeply connected, and why improving your stress tolerance starts with lowering inflammation and supporting your microbiome. Dr. D'Adamo explains the science behind cortisol, trained immunity, and the role beta-glucan plays in balancing your system long before symptoms appear.

You'll also discover why immune aging may be one of the biggest drivers of biological aging—and how supporting your innate defenses can influence longevity, energy, and mood. Throughout the conversation, you'll pick up practical strategies you can start using today to strengthen immunity in a real, sustainable way.
