A Comprehensive Look at Immunity and Supplementation, Part 1

Innate–Adaptive Balance and BWH 85 Beta-Glucan with Functional Medicine Physician Dr. Rob Rountree: He brings a nuanced view of immunity that rejects the simple “immune boosting” dimmer-switch model and emphasizes immune regulation and readiness. He reviews innate immunity as sentinel cells using pattern recognition receptors (e.g., macrophages) and explains how innate and adaptive systems interface, with innate signaling training adaptive responses; chronic inflammatory disease is framed as rooted in innate dysregulation. He reveals how immune responses can both protect and harm (candida, cytokine storm concerns during COVID) and why test-tube “stimulation” doesn’t equal human effects. The focus is a purified brewer’s yeast (Saccharomyces cerevisiae) beta-1,3/1,6-glucan (BWH 85, 85% purity), its triple-helix structure, receptors (Dectin-1, CR3), dosing (100–500 mg), evidence for improving vaccine response in elders, and potential relevance for autoimmunity, athletes, and cancer surveillance alongside lifestyle and key nutrients like vitamins A, C, D and zinc.
