Mitochondria 101
Mitochondria produce the ATP that powers every cell. Quantity and quality of mitochondria largely determine your daily energy ceiling, endurance, and cognitive stamina.
What builds mitochondria
Zone-2 cardio, strength training, sauna, cold exposure, fasting windows, and adequate protein all stimulate mitochondrial biogenesis.
Key nutrients
CoQ10, magnesium, B-complex, alpha-lipoic acid, and omega-3 fatty acids all support mitochondrial function. Food first (red meat, fish, eggs, leafy greens); supplement to fill gaps.
Frequently asked questions
- Does CoQ10 work for energy?
- Most strongly in older adults, statin users, and people with documented CoQ10 deficiency. Effects in healthy young men are modest.
- Can mitochondria 'die' with age?
- Mitochondrial function declines with age, but training and nutrition meaningfully slow and partially reverse the decline.
