both males and females, which is great.

So what you want to do is naturally boost the activity of these sirtuins.

They are genes, but they also make proteins.

That's what genes typically make or encode.

And then those proteins take care of the body in many different ways.

NAD levels are really important for keeping those sirtuin defenses at a youthful level.

I take a precursor to NAD called NMN, and the body uses that to make the NAD molecule in one step.

And so I know from

measuring dozens of human beings, that if you take NMN,

for the time period that I do.

I've been taking it for years, but if you take it for about two weeks, you'll double, on average, double your NAD levels in the blood.

So I just want people to be aware that what I do may not perfectly work at all for others.

But I have studied, as I said, dozens of people who take NMN at a gram, sometimes two grams.

And I know by looking at all those people that without any exceptions, that if you do what I do, your NAD levels go up.

by about twofold or more.

Anecdotally, because I've been taking this for a long time, if I don't take it, I start to feel 50 years old.

It's horrible.

I can't think straight.

It may be placebo, but who knows?

But what we're doing now are very careful clinical trials.
