In the course of the day, it could go up, it could go down.

If you're feeling stressed, it's clearly going to go down because it's consuming the NAD.

So it's probably not a good direct marker for aging.

But it's related to processes that could potentially help improve quality of life, extend health span, possibly even lifespan, it sounds like.

I think we've gotten to the point where we've shown that.

But as a specific marker for what your metabolic or biological age might be, I don't think it's a great marker for that.

Interesting.

Yeah, because it can be depleted by stress.

Exactly.

If you don't have a good night's sleep, your NAD levels across the board are going to be lower.

If you overexert yourself in an exercise, immediately after, your NAD levels are going to be low.

Because what do we do when we work out?

We basically damage cells.

They're immediately trying to repair themselves.

So we know it helps your health, and we know that elevating NAD levels improves your health span.

It might extend lifespan.

We don't know that, but it might.

It certainly increases health span, your resiliency of your cells, and the ability to produce energy.

But we don't really know much more than that.

Are there animal studies that you can share?
