Broadest Anti-Aging Coverage NAD+ NAD+ affects at least six hallmarks of aging through sirtuin activation, including DNA repair, mitochondrial function, epigenetic maintenance, nutrient sensing, autophagy, and stem cell function Telomere-Specific Intervention Epitalon Epitalon is the only peptide with direct telomerase activation data in human somatic cells, addressing telomere attrition which NAD+ does not directly target Strongest Human Evidence NAD+ Multiple randomized controlled trials demonstrate that NAD+ precursors safely restore NAD+ levels in humans, while Epitalon has no human clinical trial data Ease of Access and Self-Administration NAD+ NMN and NR are available as oral supplements without prescription, injection, or specialized handling, making them the most accessible longevity intervention Complementary Combination Research Epitalon Because Epitalon and NAD+ target non-overlapping hallmarks (telomere attrition vs sirtuin-mediated pathways), they are theoretically complementary rather than redundant in a multi-target longevity strategy Continue Your Research Get comparison updates We publish new head-to-head comparisons regularly
