Most supplements are a waste of money.

I’ve been experimenting with them for over 10 years.
The majority produce zero noticeable difference after three months.
And yet I still take a few. Call it insurance.
But creatine is different.
Not in a dramatic, smack-you-in-the-face kind of way. More of a quiet “huh, my brain actually works today” kind of difference.
I started taking it for muscle performance. Then I came across research on creatine and cognitive performance under sleep deprivation.
I bumped my dose from 5g to 20g a day, split into two servings.
Within days I noticed clearer thinking and better focus. My mood improved too.
When your brain is under-resourced, everything suffers. When it gets what it needs, a lot of things quietly improve.
The research is promising but not settled. The most cited study used 20g per day for 4 weeks and found a significant increase in brain creatine levels.
Do your own reading.
Get creatine monohydrate. Nothing else. If the label says anything other than creatine monohydrate, put it back.
Creapure is a higher-purity version at roughly double the price. Whether that’s worth it is your call. I use regular monohydrate.
Stomach issues? Spread your dose across 3 or 4 smaller servings through the day.
