Longevity Optimization with Kayla Barnes-Lentz Dr. Deb Rivera, PhD: The Missing Link Between Stress, Aging, and Resilience
Apr 2, 2026
Dr. Deb Rivera, neuroengineer and CEO who studies mitochondrial resilience, explains the glutathione ratio as a hidden biomarker of stress adaptation. Short, vivid stories and practical routines illustrate redox balance, mitochondria–gut ties, sleep and recovery, and environmental impacts. Conversation also covers testing glutathione, therapeutic trade-offs, and everyday ways to support resilience.

Episode notes
Glutathione Brain Cleanse Rescued Post‑Accident Vision
- Deb Rivera described post-bike-accident cognitive deficits and using glutathione plus sauna to recover visual processing.
- Two doses of oral trisomal glutathione, vitamin D, fiber and a 24-minute sauna restored her ability to read small letters.
ROS Threshold Triggers Metabolic Warburg Shift
- Inflammation is triggered when ROS exceed a threshold and metabolic flexibility collapses, switching cells into glycolysis (Warburg effect).
- This glycolytic shift reduces ROS production but promotes chronic disease and tumor phenotypes.
Unexpected Heart Tumor Found During Genetic Screen
- During genetic screening after her father's cancer, Rivera found a large atrial tumor she hadn't known about and used glutathione before surgery.
- Surgeons removed the tumor; Rivera credits glutathione and perioperative care for rapid recovery and return to activity in 120 days.
