How It Works

NAD+ is a coenzyme found in every living cell. It plays a critical role in energy metabolism, DNA repair, and cell signaling. NAD+ levels decline with age, and this decline is associated with various age-related conditions. Supplementation aims to restore youthful NAD+ levels to support cellular function and activate longevity pathways like sirtuins.
