NAD+ is having a moment - and for good reason. It’s the molecule your cells use to produce energy, repair DNA, and keep your metabolism running. But NAD+ levels naturally decline with age. And things like stress, poor sleep, and environmental damage can speed up the drop. When NAD+ falls, the systems that rely on it - energy, repair, resilience - start to slow down. Not hype. Just cellular science. #NAD #longevityscience #cellularhealth #antiagingresearch #cellularenergy #biohacking #healthyaging #agingwell #nutritionalscience #im8health
