A short YouTube monologue (Dr. Charles Mok) explaining NAD’s central role in metabolism and mitochondrial ATP production, noting that NAD levels decline with age (speaker contrasts ~50 vs ~30). The video links NAD to activation of the SIRT1 (sirtuin) pathway, which the speaker describes as a silent inflammatory regulator whose activation may slow aging; this connection has spurred interest and a "race" to identify optimal NAD supplementation forms.
