THE SCIENCE BEHIND NAD+
Every cell in your body is fueled by NAD+
Your 37.2 trillion cells are powered by NAD+, a vital coenzyme that fuels cellular energy and repair throughout your entire body. NAD+ levels naturally decline with age, lifestyle factors, and stressors. Replenishing NAD+ levels is essential for maintaining your cellular health, energy, and vitality.
