The Little-Known “Throwaway” Gland That Is CRITICAL For Immunity (& The Unexpected Peptides To Support It) - With Abud Bakri
Oct 10, 2026 · 52m
Summary
In this episode, host Ben Greenfield interviews Dr. Aboud Bakri, an internal medicine physician and former powerlifter, to explore the critical role of the thymus in immunity and longevity. They discuss how modern factors like birth control, TRT, and chronic stress accelerate thymic involution, increasing the risk of autoimmune diseases and poor immune function. The conversation covers key biomarkers such as the CD4/CD8 ratio and thymulin, while detailing interventions like thymus-derived peptides, bioregulators, and red light therapy to support immune health.
