Mitochondria

💡 Did you know? The 'good stress' of exercise — a brief burst of reactive oxygen — is the very signal that makes you fitter. Mega-dosing antioxidants around training can blunt it.

In one line: Tiny power plants inside every cell that turn food and oxygen into usable energy. Keep them numerous, efficient, and undamaged.

Picture this: Inside each cell are hundreds of little power stations called mitochondria. They pass electrons down a line (like a bucket brigade) to generate energy (ATP). With age, some break down and start leaking damage. Fitness and longevity both depend on having lots of clean, working power plants.

Step by step:

Food and oxygen feed electrons into the mitochondria's "electron transport chain."
Passing those electrons along pumps a charge across a membrane.
That charge drives the production of ATP — your cellular energy currency.
Damaged plants leak harmful byproducts, so the cell needs to recycle them.

Why it matters for you: More and healthier mitochondria mean more energy and endurance. CoQ10 is a key part of the electron line (statins deplete it, causing muscle aches). PQQ helps build new mitochondria; urolithin A helps recycle damaged ones.

Turn it up (build/protect): exercise, CoQ10, PQQ, urolithin A. The dangerous extreme: DNP forces the plants to run hot and wasteful — you burn huge energy as heat (dramatic fat loss) but it can literally cook you. People die from it.

Don't be fooled: "mitochondrial support" supplements help most when you're older or depleted; a healthy young trainee gets most of the benefit from exercise itself.
