Exercise is the main lever for mitochondrial health: steady aerobic work builds efficiency, intervals drive new mitochondria, and strength training adds more of them. Cold, heat, fasting and morning light can add to it. Mitochondria-boosting supplements are secondary and mostly unproven, and high-dose antioxidants can blunt what training builds.

Stance update (2026): Urolithin A is the mitochondria-targeted supplement drawing the most attention. It is a mitophagy stimulator from pomegranate polyphenols, called a 'third pillar of cellular health alongside diet and exercise' (Anurag Singh, on The Doctor's Farmacy). The biology is compelling in animal models but still needs human proof (Brian Kennedy, on The Drive).

Precis is not affiliated with or endorsed by YouTube or by any researcher, show or publisher we quote. We take no sponsorship, ad or affiliate money, and every verdict is our own review of what was said. How we stay independent
This report on Mitochondrial Health draws on 26 videos (48 hours analyzed) out of 3,700+ hours of recorded interviews with 380 researchers and doctors, plus 48,500+ research studies. Every mention of a claim gets a stance, and the verdict is worked out from all of them, never written by hand.
The full report adds 8 key findings and the dose and protocol. It also has the verdict on every claim, a receipt for each mention, the risks to check, and what combines with it.
