Your NAD+ Numbers Went Up. But Did You Actually Get Younger?
The supplement industry has a gift for turning a promising molecule into a simple story: your NAD+ declines with age, so you take a precursor like NMN or NR to

Aging Is Not Just Getting Old: How Science and Nature Mapped the Body's Silent Revolution
Three landmark 2026 studies reveal aging as a coordinated, organism-wide remodeling: one-quarter of 536 cell types shift with age, gut bacteria disrupt brain memory via medium-chain fatty acids, and the NAD+/NADH redox ratio, not absolute NAD+ levels, may determine mitochondrial resilience in Alzheimer's disease.
Your Cells Are Running Out of Fuel — And NAD+ Is the Key to Fixing That
By 40, your mitochondria run on half the NAD+ they had at 20. How NAD+ decline and the SIRT3 switch dim your cellular power plants, and what the science says about fighting the brownout.
