The Complete Long COVID Handbook: Volume 3 Mitochondrial Dysfunction
By Dr. Robert Groysman, MD

Millions struggling with Long COVID share the same hidden problem: their cellular power plants, the mitochondria, aren't working properly. When mitochondria falter, energy crashes, brain fog sets in, muscles weaken, and recovery feels impossible.

In this accessible and hopeful guide, pain specialist and Long COVID expert Dr. Robert Groysman explains how mitochondrial dysfunction lies at the core of many lingering symptoms. Using plain language, real-world analogies, and practical tools, he helps readers understand:

How COVID-19 hijacks mitochondria and triggers lasting fatigue, brain fog, and pain
The role of oxidative stress, mitophagy (cellular cleanup), and methylation in recovery
Everyday signs that your mitochondria are struggling-even when lab tests look "normal"
Key diagnostic tools like the Organic Acids Test, lactate/pyruvate testing, and metabolic markers
Evidence-based strategies to restore cellular energy, from antioxidants and nutrients to advanced therapies like low-dose naltrexone, metformin, and red light therapy

This volume is part of The Complete Long COVID Handbook series, which explores the six major mechanisms behind persistent symptoms: dysautonomia, mitochondrial dysfunction, gut dysbiosis, histamine excess/MCAS, endothelial dysfunction with microclots, and hormone imbalance.

If you've been told "everything looks normal" but you still feel exhausted, foggy, or unable to bounce back after COVID, this book will help you finally connect the dots and take actionable steps toward healing.

Your body isn't broken. With the right knowledge and tools, recovery is possible.
