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.
