I never ended up doing it because you had to cycle it, and it was just one more thing to track
Is it the same case in 2026? Is there a simple pill I can take?
You can just take 3-5g daily.

is not the right way to interpret the null result (insufficient evidence to reject null hypothesis that it has no effect) because the prior for supplements that people are trying to sell you is so low. In the absence of clear, strong evidence, you should assume the the whole thing is just an example of motivated reasoning. People want nootropics to be real, and other people really want to sell you readily available powders by claiming they have nootropic properties. In that environment, they were always going to trying to concoct a similar narrative about some supplement, and it just happened to be creatine. Those efforts were always going to result in a handful of "positive" studies that turn out to be non-reproducible, maybe because of p-hacking, maybe because of publication bias, maybe because of outright fraud. This is what the literature always looks like for stuff that just doesn't work. If it did work - if the effect size was large enough that you could personally detect it in your own life - then the papers would be trying to put error bars around the effect size, not trying (and failing) to barely distinguish it from a placebo.

Like being tired, stressed, etc...
Here are the sleep deprivation studies
It safely builds muscle and boosts cognition.
More like "probably", "yes", and "probably not."
If I know I'm only going to get a few hours of sleep, I'll take 5–10 g of creatine, drink plenty of water, and go to bed. The next morning, I usually don't wake up with a headache.
If I skip the creatine under the same conditions, I'm much more likely to wake up with a headache after a short night's sleep.
Now it's become a habit, I automatically take creatine whenever I know my sleep duration is going to be much shorter than usual.

>Headache pain often appears along with other signs and symptoms of dehydration, including darker-than-usual pee, dry mouth and fatigue
none of these symptoms are true for me.
They missed a zero behind the comma, didn't they?
The one thing this misses is many supplements are tainted, which skews the popular perception of both upsides and risks. This was especially true in the US prior to 2005 or so when prohormones were still legal over the counter. Anything branded that wasn't just pure creatine was extremely likely to actually be a low-dose oral steroid, which really can make you lose hair and will increase strength quite a bit more than any dietary supplement.
This also misses caffeine as the other a-tier supplement that consistently shows strength increases in RCTs, though of course, caffeine is more frought than creatine because you build tolerance and it can disturb sleep.
Perhaps you can say "danger to your hair is rare", but there's very clearly (to me at least) an effect there, and the way it gets hand-waved away is strange to me.
In college Ripped Fuel wasn't banned yet. We would take two, go to the gym for 2 hours, shower, then go out until the sun came up the next day. It's no surprise it was eventually banned. I think some people ended up dying by taking too many.
this is wrong [0] , it's just hard to measure.
If it’s really hard to measure because the amount is so small that it requires precise equipment, it’s not significant relative to the rest of the body’s energy expenditure.
Just having the desire to think makes a huge difference.
if you truly want fuel for the brain nothing beats keto
Is creatine safe to supplement for children?
Up to 50 Cal extra over ~2 hours of intense thinking IS significant given brains consume 240-400 Cal over 24 hours.
> Start thinking hard, and watch as your heart rate does not increase.
And yet you soon get tired and slow down. Now try the opposite. Stretch or punch the air a few times to get the heart rate going. You'll sustain brain performance for longer. Try it.
Perhaps the problem is that higher brain activity SHOULD trigger heart rate increase, but doesn't due to one of many design defects of the human body.
The vegan/vegetarian is a big spectrum. A vegetarian eating plenty of dairy products and eggs should in theory be much better creatine-equipped than a poor vegan student feeding on noodles and ketchup pastas. A lot of pseudo-meat for vegans are full of processed shit.
Confusion will be even higher if you include fish in the vegetarian diet, which is odd but some people do that.
Could the cognitive effect works in the case of creatine deficiency (vegan) and not in the case a vegetarian (low creatine but not deficient) ?
As for pills, yes, there is about every form of creatine supplement now, even chewing gum, but this is just dumb, how much of creatine do you think you can consume this way in a day?
I think mostly through placebo effect, people buy a supplement to treat condition X and they think it's getting better, so they keep buying.
I mean, just look at the wide variety of homeopathic "cures" that are often so diluted that there might not be any molecules of the active ingredient left. Yet people keep buying it.
Their conclusion seems like an absolutely fair interpretation of what they saw, and it also strikes me as dangerous -- perhaps more dangerous -- to suggest "writer genuinely believes, or doesn't believe, a thing, but they should say it differently from their own interpretation because..people are dumb?" Something like that.
That's why I dropped creatine since I didn't notice any benefits when I tried it for a year.
Basically, HN doing HN things - having a good deep think about topics outside their realm of expertise, then debating the minutiae. I'd just rather trust someone who has spent their career researching this stuff, thanks (unless that's what you do - in which case please tell us more).
So drinking water part is consistent with or without creatine. I do know the creatine takes a while to build up, so i don't know why it works but it does.
There's also no shortage of expensive water bottles being sold, and smart water bottles that track your drinking frequencies and flavor pods sold via subscription.
Anecdotal so safe to ignore this… but my hair did thin out but only after I was lazier on my work outs. Stopped taking and hair mostly returned to normal thank God.
Since taking creatine I feel so much more energized. I can make it through the day with just 2 coffees (was previously drinking 5 coffees and an energy drink).
Maybe it's placebo. Maybe it's not. I don't really care. I feel the benefit and I love it.
