What is NAD and why is it important to measure?
NAD keeps your cells running smoothly. It’s involved in DNA repair, energy production, and fighting inflammation.
Your body uses NAD for more than 500 cellular activities every day. These include making ATP (cellular energy), supporting your immune system, and regulating sleep.
As NAD declines with age, you may notice lower energy, slower recovery, and reduced mental clarity. Many age-related health concerns trace back to insufficient NAD.
Testing reveals your current levels so you can take action. You can’t optimize what you don’t measure.
When NAD levels are optimal, your cells repair themselves better and produce energy more efficiently.
