Every cell has NAD+.

It's critical for energy and cell repair.

And inside our cells, we have NAD+, and it's helping our mitochondria.

So these are the little tiny, tiny energy-producing structures or organelles within our cells that are converting nutrients into usable energy, into ATP, particularly.

Really good.

Very good for brain health as well.

And it's also involved in activating a group of proteins.

You might have heard of these.

They're called sirtuins.

And these are sometimes referred to as longevity pathways because they regulate things like DNA repair and inflammation, cell aging.

And the challenge is that NAD+, these levels that we have in all our cells, they decline as we get older.

And that's why there's growing interest in ways to either support or to replenish it.

Now, because NAD Plus itself is very difficult to absorb as a supplement, most products that are on the market contain what's called a precursor.

So a precursor is something pre, so it's before the actual ingredient.

So in this case, it's giving you something that the body will then convert into NAD Plus.

And the most common ones are NMN, nicotinamide mononucleotide, or NR, nicotinamide riboside.

So NMN or NR, these are the precursors to NAD+, okay?

I think maybe you should get a pen and paper because you might want to write a bit of this down.

So NMN and NR, very good.

They are designed as supplements to help the body boost its own NAD+.
