Research Notes

A coenzyme present in every living cell, central to energy metabolism and DNA repair. Research shows NAD+ levels decline significantly with age, roughly 50% between ages 40 and 60, which has made it one of the most active areas of cellular aging research. What the research explores: mitochondrial energy production pathways, sirtuin enzyme activation (proteins linked to cellular aging processes), and PARP-mediated DNA repair mechanisms. NAD+ research sits at the center of the broader scientific interest in cellular aging and metabolic decline. What it isn't: an anti-aging treatment. NAD+ is a coenzyme, not a peptide, but its central role in the cellular processes IRIX researches earns it a place in this lineup. The research correlating NAD+ decline with aging is well established; reversing that decline in humans remains an active and unresolved research question.
