Well, hello, hello, guys. You're listening to Beauty Bites with Dr. K., Secrets of a Plastic Surgeon,

and it's time for a five-minute

Friday. Today, we're going to talk about NAD. I know you guys have been hearing all about NAD.

What the heck is NAD? Why is everybody jumping on board trying to take NAD for cellular health,

longevity, wellness? Let's dive right in.

Nicotinamide, adenine, dinucleotide. That's what NAD stands for. This is emerged as one of the key molecules in the science of aging and longevity. And it is often regarded as a superhuman molecule.

It's critically important to our cellular health.

As we age, NAD levels drop off precipitously.

They disrupt the balance of energy production in the cell.

There's a balance between synthesis, making NAD for energy cycling through your mitochondria,

and consuming NAD for all of the cell repair mechanisms, the DNA repair, the molecules that get damaged by oxidative damage.

There's a whole process that requires energy to maintain cell health. The decline of NAD is really

profound as we age, and I attribute it to that feeling

of adult tiredness. You know how it is. You sleep for eight hours. You get up out of bed,

and you're just like, why am I dragging? Why am I not bouncing, jumping, and singing like children do?

It's because we get adult tiredness.

It's our NAD levels decline almost 50% from age 20 to age 40.

And this definitely is integral for numerous biologic processes, DNA repair, cell metabolism,

activating your Sertuins. These are the family of enzymes that regulate

aging and longevity. NAD helps Sertuins to repair damaged DNA, reduce inflammation, and promote function.

And as your NAD levels drop, your body becomes less efficient. It can't repair DNA as well and you can't maintain

cellular integrity. This leads to inflammation, slower metabolism, visible signs of aging like
