Hi Pooja! Thank you for sharing your feedback on Qualia NAD+! NAD+ is a critical molecule found in every cell in your body: it’s involved in hundreds of metabolic processes. NAD+ is most well-known for being involved in turning the energy in food into cellular energy (it’s a key player in metabolism) and regulating cellular functions related to maintenance, repair, and stress. Your health starts with your cells; their health creates your health. And, cells need adequate amounts of NAD+ to support many of the metabolic processes they rely on to stay healthy. NAD+ became an area of much greater scientific interest because of two things: the realization that NAD+ levels decline with age and the recognition that replenishing NAD+ to more youthful levels supports cellular health.
