Brain Fog, Fatigue, and the Hidden Role of Mitochondrial Dysfunction
Are you struggling with persistent brain fog, low energy, or chronic fatigue? These symptoms are often overlooked or misattributed, but at Transform Wellness Clinic, we uncover their root cause: mitochondrial dysfunction.
Mitochondria are the energy factories of your cells, producing 32–36 ATP (our cellular energy) per glucose molecule through oxidative phosphorylation (OXPHOS). When mitochondria are impaired, energy production plummets to just 2 ATP from anaerobic glycolysis, leaving your brain and body in an energy crisis. This can manifest as poor memory, mental sluggishness, and unrelenting fatigue.
This blog explores how mitochondrial dysfunction drives brain fog and fatigue—and what you can do to reverse it.
1. Oxidative Stress
Mechanism: Excess reactive oxygen species (ROS) damage mitochondrial membranes & mitochondrial DNA (mtDNA), and electron transport chain (ETC) proteins, stalling ATP production.
