So any kind of stressful condition, that's where creatine shines in the brain.

I would argue that...

All of us, who has the perfect amount of sleep, never has stress?

Nobody, right?

There's always some sort of stress in the background.

So that's when I was like, okay, so if you're the perfect person, you have no stress, you get the perfect amount of sleep every night, your brain makes enough creatine to kind of do what it needs to do.

I know that I'm constantly under stress.

So I'm like, okay, well, I think I need a boost.

And this is where a lot of very interesting studies have come out of many different labs, some out of Germany that looked at the dose of creatine and how it increases creatine levels in the brain.

And this is why I now supplement with 10 grams a day.

So the study out of Germany...

found that five grams a day of creatine, if you're supplementing with five grams a day, your muscles are greedily consuming it, particularly if you're working out.

They want it.

They want it.

After about five grams a day, especially over a few months, like you're saturating your muscle and that's enough, right?

Anything above that kind of spills over to the brain.

And so what this German study found was that 10 grams of creatine increased creatine levels in several different regions of the brain.

And that was probably the most exciting, you know, I would say, evidence that supplementing higher than 5 grams a day was actually doing something in terms of getting creatine into the brain.

There have now been a variety of studies that have looked at different outcomes, right?

So if you supplement with 10 grams of creatine or even go higher than that, like 20 grams of creatine, how does that affect cognitive function, right?
