Urolithin A (specifically via the purified formulation Mitopure) does not technically rewrite your chronological DNA, but it fundamentally rejuvenates cellular age by restoring a vital clean-up process called mitophagy (selective mitochondrial recycling). As cells age, mitophagy efficiency drops, leading to an accumulation of damaged, energy-depleted mitochondria. Mitopure triggers a unique calcium-dependent signaling cascade that stimulates the endoplasmic reticulum to release calcium ions, acc
