NAD+ gets called the “fountain of youth” molecule a lot.
And while that’s certainly good marketing, there is some really interesting biology behind why NAD+ has become such a major topic in longevity research.
NAD+ is a coenzyme found throughout the body. Your cells depend on it for mitochondrial function and energy metabolism, but its role goes much further.
NAD+ is consumed by enzymes involved in DNA repair and cellular signaling. It’s also closely connected with sirtuins — proteins researchers have been studying for their roles in cellular stress responses, metabolism and aging.
And one of the reasons the longevity world is so interested in NAD+?
NAD+ availability tends to decline with age.
That has led researchers to investigate whether preserving or restoring NAD+ biology could influence different aspects of age-related cellular function. That research is exciting, but it doesn’t mean we’ve discovered a literal fountain of youth — or that everyone needs supplemental NAD+.
That’s the distinction we care about at LUX.
If you’re exhausted, traveling constantly, struggling to recover from a demanding lifestyle or interested in supporting cellular health as you age, NAD+ may be a conversation worth having.
But we’re still going to ask about your sleep, nutrition, hydration, stress and lifestyle first.
Sometimes NAD+ makes sense.
Sometimes the basics need attention first.
And if NAD+ does make sense, we can talk about whether an IV infusion or smaller, more frequent injections better fit your goals and lifestyle.
