Is this you?

You did one normal thing yesterday. Today you are paying for it.

A trip to the grocery store, a walk with the dog, a work call that ran long. Twenty-four hours later your legs are lead, your head is cotton, and nobody around you can see why. You have learned to ration yourself like a battery that never fully charges.

Here is what is happening inside the cells that make that energy, what we can measure, and what we can treat.

The mechanism

What Mitochondria Do

Every cell in the human body contains hundreds to thousands of mitochondria — tiny organelles responsible for producing adenosine triphosphate (ATP), the universal energy currency of life. Your body produces and consumes roughly its own weight in ATP every single day.

Mitochondria convert nutrients from food and oxygen from breathing into ATP through a complex process called oxidative phosphorylation. This process involves five enzyme complexes (Complexes I-V) in the electron transport chain, each of which can be damaged by infections, toxins, oxidative stress, or nutritional deficiencies.

When mitochondria are impaired, cells do not receive enough energy. The organs most affected are those with the highest energy demands: the brain, heart, muscles, and immune system. This explains why mitochondrial dysfunction produces such a wide range of symptoms — from cognitive impairment to cardiac dysfunction to immune failure.

Mechanisms of Failure

What Damages Mitochondria?

Viral Infections

Viruses including SARS-CoV-2, EBV, and HHV-6 can directly damage mitochondrial membranes, hijack mitochondrial machinery for viral replication, and trigger mitochondrial apoptosis pathways. Post-infectious mitochondrial damage is a key driver of both Post-COVID and CFS.

Oxidative Stress

When mitochondria are stressed, they produce excessive reactive oxygen species (ROS) that damage their own membranes, DNA, and enzyme complexes. This creates a vicious cycle: damaged mitochondria produce more ROS, which causes further damage.

Nutrient Deficiency

The electron transport chain requires specific cofactors to function: CoQ10, NAD+, riboflavin (B2), niacin (B3), iron, magnesium, and others. Deficiency in any of these can create bottlenecks in energy production. Many CFS patients show multiple subclinical nutrient deficiencies.

Toxic Exposure

Heavy metals (mercury, lead, aluminum), pesticides, mycotoxins (mold toxins), and certain medications (statins, fluoroquinolone antibiotics) are known mitochondrial toxins. Environmental toxin exposure is an underrecognized contributor to CFS.

Chronic Inflammation

Pro-inflammatory cytokines (TNF-alpha, IL-1, IL-6) directly impair mitochondrial function. Chronic low-grade inflammation -- from any source -- gradually erodes the mitochondria's ability to produce energy efficiently.

Hormonal Imbalance

Thyroid hormones directly regulate mitochondrial biogenesis and function. Cortisol dysregulation impairs cellular energy metabolism. Sex hormones influence mitochondrial efficiency. Hormonal imbalances compound the energy deficit.

What we test

How We Assess Mitochondrial Function

Standard laboratory tests do not evaluate mitochondrial health. At St. George Hospital, we use specialized testing to map the specific nature of each patient’s mitochondrial dysfunction:

  • ATP Profile Test: Measures actual ATP production capacity, ATP recycling efficiency, and identifies which mitochondrial complexes are impaired
  • Organic Acid Testing: Urinary organic acids reveal metabolic blocks in the citric acid cycle and electron transport chain
  • Oxidative Stress Panel: Measures lipid peroxidation, 8-OHdG (DNA damage), and antioxidant capacity
  • CoQ10, NAD+, and Cofactor Levels: Direct measurement of essential mitochondrial cofactors
  • Lactate/Pyruvate Ratio: Elevated ratios indicate a shift from aerobic to anaerobic metabolism
  • Intracellular Mineral and Vitamin Analysis: Red blood cell mineral levels and functional vitamin testing

Treatment

Mitochondrial Repair Therapy

Our mitochondrial support protocol is designed to restore ATP production, reduce oxidative damage, and rebuild mitochondrial capacity. Treatment is guided by individual test results and adjusted based on clinical response.

IV Micronutrient Therapy

High-dose intravenous delivery of CoQ10, NAD+, alpha-lipoic acid, B-complex vitamins, magnesium, and glutathione bypasses absorption issues and achieves therapeutic intracellular concentrations not possible with oral supplements alone.

Detoxification

Removal of mitochondrial toxins -- heavy metals, mycotoxins, environmental pollutants -- through targeted chelation, liver support, and apheresis eliminates ongoing sources of mitochondrial damage. c

Antioxidant Support

Breaking the oxidative stress cycle with IV glutathione, vitamin C, and targeted antioxidant therapy protects existing mitochondria from further damage and creates conditions for mitochondrial biogenesis.

Oral Maintenance Protocol

After the intensive IV phase, patients continue with a carefully designed oral supplement protocol -- CoQ10, PQQ, D-ribose, acetyl-L-carnitine, and B vitamins -- to maintain and build upon gains achieved during the inpatient stay.

Mitochondrial Dysfunction Also Affects

Mitochondrial dysfunction is not exclusive to CFS/ME. It plays a central role in several conditions we treat at St. George Hospital:

Lyme Disease

Borrelia and co-infections impair mitochondrial function, driving the fatigue of chronic Lyme.

Mitochondrial decline is a hallmark of aging. Supporting mitochondrial health is central to longevity medicine.
