Your cells create energy through a process called cellular respiration, where nutrients like glucose are converted into ATP, the body’s main energy currency. NAD+ is a critical part of that system. It works as an electron carrier, NAD+ collects electrons to become NADH, and delivers them into the mitochondria to drive ATP production. 

 NAD+ is present in almost every cell in the body, especially in high-energy tissues like the brain, heart, muscles, and lungs. Beyond energy, it also acts as a coenzyme, helping activate proteins that regulate metabolism, repair DNA, and keep cells functioning efficiently. In short, NAD+ helps your body turn food into fuel, repair daily cellular damage, making it foundational to long-term vitality and performance. NAD+ is fundamental to maintaining overall cellular health, helping to slow the ageing process and reduce the risk of disease.
