The Verdict

This is one of the most divisive topics among our 5 experts. Attia categorizes NAD supplementation as 'noise' on his evidence hierarchy, while Hyman actively advocates for NAD precursors as part of a longevity stack. Huberman personally takes NR and NMN for subjective energy but explicitly not for longevity. Patrick provides the most balanced scientific coverage, noting promising animal data but significant gaps in human evidence.
