Mitochondrial Dysfunction

Mitochondria make the energy every cell runs on. We remove what burdens them, from toxins and infections to blood sugar swings, then rebuild energy with nutrients, light, heat, cold, and movement.

What you may be noticing

Fatigue that sleep does not fix. Muscles that tire quickly. Brain fog that worsens with effort. Exercise that drains rather than energizes. Sensitivity to cold. A sense that your battery is smaller than it used to be.

Why it is rarely one thing

Mitochondria convert food and oxygen into ATP, the molecule that powers muscle contraction, nerve signaling, detoxification, and repair. Neurons are among the most energy-dependent cells in the body, which is why brain fog is often one of the first signs of an energy shortfall. The heart and muscles also carry high demand.

Primary mitochondrial diseases are genetic and relatively rare. Far more common is secondary mitochondrial dysfunction, in which mitochondria are impaired by their environment: toxins and heavy metals, mold, some medications, chronic infections, insulin resistance, chronic inflammation, nutrient deficiencies, and inactivity. Not a lack of energy, but a factory that cannot produce enough.

Mitochondria are dynamic. They divide, fuse, are recycled through mitophagy, and are rebuilt. Exercise is among the strongest signals for new mitochondria. Heat exposure activates heat shock proteins that help protect cellular proteins, and cold exposure activates brown fat mitochondria; how much these practices add in a given person is still being studied. Nutrients matched to your individual genetics and needs give each cell the cofactors it requires.

Patterns we look for

• Nutrient cofactors: B vitamins, magnesium, CoQ10, carnitine, iron, and alpha-lipoic acid.
• Organic acid markers of energy metabolism and glutathione demand.
• Blood sugar regulation and insulin resistance.
• Toxic burden, including mold and heavy metals.
• Chronic infections and viral reactivation.
• Inflammatory markers and oxidative stress.
• Thyroid function, especially free T3.
• Medications that affect mitochondria, such as statins.
• Post-exertional malaise and muscle mass.

How I evaluate it

The comprehensive functional neurological exam assesses fatigue under repeated testing, eye movement endurance, balance, and autonomic responses, since mitochondrial strain often shows as performance that drops with repetition.

Functional labs may include an organic acids test, which shows how the energy cycle and detoxification pathways are running, a comprehensive metabolic panel, fasting insulin, ferritin, B12, magnesium, a full thyroid panel, inflammatory markers, genetic nutrient testing, and toxic burden testing when indicated. I refer for genetic evaluation when a primary mitochondrial disease is suspected.

How we address it

• Open drainage pathways and lower toxic, infectious, and inflammatory load first.
• Stabilize blood sugar and improve insulin sensitivity.
• Replete nutrient cofactors matched to your labs and genetics.
• Begin each day with morning sunlight.
• Build mitochondria with resistance training and steady aerobic work matched to your tolerance, paced if post-exertional malaise is present.
• Add sauna, gentle cold, and red light where tolerated.
• Protect sleep and support brain energy with functional neurology that stays within your capacity.

Energy is made, not found. When the burden lifts and the signals return, the factory rebuilds.
