“NAD+ is a molecule found in every cell of your body. It plays a key role in how your cells produce energy and repair damaged DNA. As we age, NAD+ levels naturally decline, which may contribute to many of the changes we associate with getting older.”
Why NAD+
NAD+ declines with age. Supplementing can help replenish it.
NAD+ drops with age
NAD+ levels drop steeply with age. Direct measurements in human tissue found levels of 8.5 units at birth, 2.7 units in young adults, and just 1.1 units in people over 71 — an 87% decline over a lifetime.

HOW NAD+ WORKS
Powers cells. Activates repair.
NAD+ is a coenzyme that cells use to turn nutrients into energy. It fuels two enzyme families — sirtuins and PARPs — that regulate DNA repair, inflammation, and aging processes.
Supports cellular health
NAD+ fuels cellular energy and supports antioxidant defense. Subcutaneous delivery can replenish NAD+ levels and support healthy cellular function as those levels decline with age.
Fuels energy production
NAD+ converts nutrients into ATP (Adenosine Triphosphate), the energy source that powers every living cell.
Activates repair pathways
Sirtuins and PARPs (enzyme families that depend on NAD+) help repair damaged DNA, regulate inflammation, and influence the processes linked to cellular aging.
