Why NAD+ Levels Fall, and Why It Shows Up the Way It Does
NAD+ is a coenzyme your cells use in over 500 enzymatic reactions. Your mitochondria need it to produce ATP. Your DNA repair machinery needs it to function.
What changes with age is how much of it you have. Clinical research puts the decline at roughly 50% between ages 40 and 60.That drop doesn't announce itself clearly. It shows up as energy that isn't as reliable as it was, recovery that takes longer than it should, or a mental sharpness that's harder to access than it used to be. A NAD+ supplement addresses the supply side of that equation. But supply is only part of the problem.
