And I want to caveat this.

There was no placebo control.

But it did show that giving people with Alzheimer's disease creatine, I believe it was 20 grams a day, did improve their cognition.

And so, again, this is a whole new field where now we're looking at creatine in the brain, not just the gym bros and not just the muscular effects, but in the brain and how it's affecting the brain and being beneficial for cognition, for brain aging, for depression.

So I published a study on a thousand marijuana users, compared it to our healthy group.

Every area of their brain was lower in blood flow and activity.

And then just this year.

Measurably.

Measurably.

On the imaging study we do, which is called SPECT, S-P-E-C-T, single photon emission computed tomography.

It looks at blood flow activity, but also looks at mitochondrial function.

So the mitochondria are little energy powerhouses in your cell.

They activate and keep the cell energized and alive.

And 49% of the tracer that we do this study with is actually taken up by the mitochondria in the brain.

So when we see low activity, it's really low activity along with decreased blood flow.

And then there's a new study by a completely separate group than ours on a thousand young marijuana users.

And the areas of the brain involved in learning and memory were low.

and blood flow and activity.

So it's not just me because I have a problem with marijuana.

So it can go with tiredness.
