“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.”

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.

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.

Fuels energy production

NAD+ converts nutrients into ATP (Adenosine Triphosphate), the energy source that powers every living cell.
