NAD+ is a coenzyme essential to how cells convert nutrients into energy and how repair enzymes like sirtuins operate. Its levels are studied for declining with age, which is the core of the longevity interest.
Research investigates NAD+ and its precursors for mitochondrial function, cellular-repair signaling, and biological-aging markers. It is studied via several delivery approaches in the research setting.
