Do NAD Levels Decline As You Age?
And if so, by how much? Scientists are clear that NAD levels decline over time...
It has been well established that NAD+ level decline with age. By middle age, our NAD+ levels may have plummeted to half that of our youth.
However, it varies by tissue type. NAD levels in skin appear to decline by at least 50%.
The NAD decline in human brains may be closer to 10%-25%.
Human liver samples from patients over 60 years old exhibited an approximately 30% decline in NAD+ compared to samples from patients who were 45 years old or younger.
