# Mitochondria and Longevity

No mitochondria supplement matches what exercise, sleep, and how you eat do for your cells, because the master switch for building new mitochondria (PGC-1α) answers to muscle contraction and energy stress, not capsules. Among supplements, only four have strong mechanism: CoQ10 (with one solid heart-failure trial, Q-SYMBIO), riboflavin (B2), an NAD+ precursor (NR or NMN), and taurine, and most of their longevity claims rest on mechanism rather than proven human outcomes. Treat any "mitochondrial booster" sold as a replacement for training as the weaker, pricier option.

Honest evidence on cellular energy, the supplements worth your money, and the free moves that beat every pill.
