Mitochondria & Cellular Energy.
Mitochondria produce most of the energy every other function depends on. Aspects of that function can be assessed, and much of it responds to how you live.
Mitochondria produce most of the energy every other function in the body depends on. Energy, cognition, metabolic health and recovery all relate to how well they work. Aspects of that function can be assessed, and lifestyle and clinical measures can support it.
The system
What it is, and why it matters.
- What it is
- Mitochondria are the cellular engines that turn food and oxygen into ATP, the energy currency every other process in your body runs on. They are also the site of fatty acid oxidation, the TCA cycle, and the electron transport chain. They regulate apoptosis, calcium signaling, and inflammation, so when they falter, the consequences extend far past energy.
- Why it matters
- Your energy, cognition, metabolic health, and rate of recovery all depend on mitochondrial efficiency. When mitochondria slow, you feel it as fatigue you cannot sleep off, brain fog that does not lift, and a body that no longer responds to training the way it used to. Mitochondrial decline is also one of the strongest drivers of metabolic and neurodegenerative disease over the long arc.
- What I read for
- TCA cycle intermediates on a urinary organic-acid profile. The lactate-to-pyruvate ratio for clues about anaerobic shift. Cofactor status, especially CoQ10, magnesium, B vitamins, iron, and carnitine. The pattern across markers tells me whether the bottleneck is upstream substrate, the cycle itself, or the electron transport chain.
