Why Your NAD+ Levels Drop (Stress, Sleep, Aging Explained)

In Part 1, I explained what NAD+ is and why it’s essential for cellular energy, DNA repair, and healthy aging. In Part 2, we focus on the less-discussed side of the conversation: what actually breaks NAD+ down — and what helps support it over time. This video covers: • Why NAD+ demand increases with age • How DNA damage and chronic inflammation consume NAD+ • The role of stress, poor sleep, alcohol, and metabolic strain • Why lifestyle factors matter more than any single compound • How to think about NAD+ support without shortcuts or hype Key takeaway: NAD+ decline isn’t random — it reflects cumulative stress on the system. Supporting NAD+ means reducing unnecessary drain while improving recovery and resilience. This content is for educational purposes only and is not medical advice.
