Good discussion, but this conclusion:
> I don’t know. Maybe a little.
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.

I think this is quite different because (1) creatine has been proven to be completely harmless for people of all ages absent some rare thing like a kidney disorder and (2) it has a bunch of clearly measurable positive effects.
So this is more like trying to determine whether ginseng is good at keeping away colds or whatever. Maybe it does (actually quickly searching this, it definitely does but let's pretend it's as folksy as it sounds for a minute) but even if it doesn't then it's harmless and has a bunch of other effects, so when one takes it - the whole possible cold prophylaxis can just be seen as an added perk.
chmod775 1 days ago [-]
Issue being that if you took everything that's "probably harmless" at once, cramming your body full of supplements, you might just end up harming yourself with substances that are toxic above certain amounts (acute iron toxicity etc.). Also the more random stuff you take, the more likely it is that something you took actually does turn out to have been harmful later.
So no, you should not take something merely because it's "probably harmless".

You and I should not. But I'm also not going to bother correcting someneone taking homeopathy for a cold. It doesn't do anything. But unless it contains heavy metals, it also isn't hurting.
When I found ivermectin in my father's fridge, on the other hand, I absolutely asked him what he was taking it for. When I confirmed he's also taking real medicine, I dropped it provided he told his doctor in case there are drug interactions. (There aren't. Ivermectin is pretty safe. That's why the nutters congregate around it.)

This is basically "wanting" it to be true then it actually being there are so many variables and so many other things that even the minuscule benefit you gain from this heavily marketed science backed supplement could get completely offset by your other lifestyle problem like poor inconsistent sleep. I at one point was deep in this "optimizing" phase listening to all these pseduo-intellectual channels like "What I've Learned" and articles like the one linked and they always overblow the finding to support some conclusion. I tried creatine for full year and didn't felt any different no extra 20% energy nothing still fatigued after work same with fish oils all this stuff is at best either placebo or in case of creatine only tiny benefits that might only be felt by someone really at peak of their training.
The actual things that I now swear by and actually help is consistent sleep of whatever hours that doesn't make you feel sleepy in the day/night (depending on shift) since actual consistency matters more then timing and also in case of workouts really balancing the fatigue to intensity ratio. I understood this late and thought one should always push hard but there needs to be a balance. It's kind of like how cheetah can run really fast but only for 20-30 seconds and then it needs a 30 minute reset period or something. So if you go to failure or always at very high intensity it affects later sets and increases recovery period and in a way driving down overall weekly sets/volume which is main hypertrophy factor.

My lay person understanding is that supplemental creatine screws with a common lab test to screen for kidney problems. Let your physician know if you are taking any supplements so they can interpret your lab test results appropriately or order different tests.

People have no idea how successful big pharma’s info campaign has been since what I’m increasingly calling the real Web 3.0 (post-influencer social media and arrival of big corporate narratives).
According to Reddit, Epsom salt has no effect (doesn’t absorb) - you’re wasting your time by using it. They’ll cite all sorts of real, funded studies that agree and yet always the comment section is filled with anecdotal evidence of the contrary - to which a typical response is “hot water in general is soothing” (ignoring efficacy of magnesium sulfate in ice baths).
I digress - creatine is a similar situation. All this confusion at best. It’s also not unlike the health effects of cannabis just prior to going effectively legal - it either causes or cures cancer, or something? We need more research! That’s the real problem!
Any time you see this sort of narrative it’s corporate politics and influence at play.
By virtue of how hard it is to get any information on creatine, it probably threatens some market or vertical at least (whether or not it “works”). Like A. muscaria mushroom or sassafras, you’ll have to do your own research to really know.

Drinking the same Epsom salt in water that you soak in has the same effect as soaking in hot or cold water with it, and it's also the same effect as taking magnesium supplements sold over the counter.

They're not saying "one point" about the conclusion, they're saying that their statement isn't nearly confident enough, and that they would prefer that they say with strong confidence that there is unequivocally NO positive effect on cognition.
It is a hell of a thing for a random person on an internet forum to be so unilateral, without providing some kind of strong evidence (aside from statements about "the industry", which is kind of beside the point). I would also suggest if you want to be so unequivocal, that the burden of proof is especially high for you.
This "point" isn't actually all that rational - it's knee jerk skepticism. It's a fine default for yourself, but it's not something you get to force on others because they admit there's room for the potential of benefit.
Again: You're perfectly fine to hold that opinion yourself, but when you start trying to force that on others - you now have an especially high bar to reach, and yes - being a lead researcher in the field is exactly what I'm looking for when someone says "X has been proven to not have a benefit for Y".
"Trust me, I'm a scientitian" - Not sure the point of that juvenile wordplay, but Ok: we do have these things called scientists, some are good, some are terrible. You still need to back up your statements - that's the key part, this isn't a blind appeal to authority. And it's a hell of a lot better than "Trust me, I'm a nerd with very strong beliefs about a topic I know very little about".

That's why I dropped creatine since I didn't notice any benefits when I tried it for a year.
somenameforme 1 days ago [-]
With most industries companies live and die by their reputation. Find a bulk provider with a positive reputation and the creatine you buy is almost certainly going to be safer than e.g. eating at Taco Bell. And with creatine in particular it's so dirt cheap that a lot of motivation for dodgy stuff goes away unlike e.g. with protein powders where amino acid spiking can save a company a bunch of money. And incidentally creatine is one of the substances dodgy companies use for amino acid spiking, just because it's so cheap!
That said it's obviously the right decision to drop it if you're not seeing any effects. The interesting thing about creatine is that people's bodies are very different in their natural levels of creatine, and if you're already at 'saturation' then more creatine isn't going to do anything. Same reason the typical benefits of creatine don't show much difference beyond 5g/day. That's enough to send the overwhelming majority of people towards 'saturation.'

Are there really downsides to creatine though? (Genuine question). All the advice I've seen makes it seem like it's basically just good for you even if it doesn't accomplish some specific thing. The only downside I've heard is maybe water retention?
ttul 24 hours ago [-]
That's not the point. Often in medicine, the downside of using one thing is that you're not using another thing that would be safer and more effective. When people chase results from unproven therapies, often it means they're avoiding doing something else that is known to produce a result - even if the result of the alternative is not as spectacular as the unproven therapy promises to be.
But speaking of creatine itself, while not inherently toxic, consuming large doses can cause serious indirect harms, such as triggering falsely elevated kidney markers on blood tests that lead doctors to misdiagnose organ failure, unnecessarily cancel crucial medical treatments, or order invasive biopsies. Furthermore, overloading the body with creatine while taking kidney-stressing medications (like heavy doses of ibuprofen) or having an undetected renal condition can cause actual acute kidney strain, while the massive shift of water into muscle cells can trigger severe dehydration, heat exhaustion, and electrolyte imbalances during intense heat or exercise if fluid intake falls behind.
But, I don't want to belabour the point about creatine. Rather, I want to focus on the negatives stemming from NOT doing other things that ARE proven to be safe and effective. People tend to think creatine will solve a lot of their problems (for instance, they may believe it will fix their feeling of being "low energy). But by avoiding things that might actually help their problem get better, they're persisting a poor state of health.
freehorse 13 hours ago [-]
Taking creatine does not bar you from doing other things. Being "low energy" is too general a thing, and to approach you probably need to start eliminating factors anyway until you find the issue, by getting better sleep, doing blood tests etc. Taking creatine can be part of this.
Creatine supplementation not having significant effect in X domain in population level does not mean that it will not have effect on YOU if for example you are vegan and don't get enough creatine from diet. If you have low energy, probably you have something that may not show in a population level. Similarly you may be low in B12 and then B12 can help you, but it may not show effects in population level if most of the population is not low in B12 (and your study is not powered enough to catch nuances).
It is not like when you have to choose between two medicines and excluding one can be harmful even if the other is not harmful to take per se. You can supplement creatine and try whatever else at the same time.

The author is not understanding that each experiment is independent.
The correct cartoon should show researchers trying green jellybeans 100 times, with 99 negative results and one positive result, and then the press keeping only the positive (Or in this comic, claiming that all jellybeans produce acne).
Mocking the scientific method, and showing scientists as lazy people that play video-games is funny, but is just a cartoon, not the reality. People should not take XKCD as god's speech without any critical thinking. This in your workplace says to me "I don't really understand statistics".
There is an effect that is statistically rare just by chance, AND is consistently absent within a huge control group of "non-green jellybeans" (the author seems to think that this weakens the result, but in fact is reinforcing it). And it needs further research. Not less, not more.

Jellybeans here are irrelevant (They are present in both groups, the control and the experiment). It may be, or not be, a random correlation, we can't know at this point. And this leads us directly to the next line:
> A positive result is no more deserving of further investigation than a negative result.
This is not how science works.
Your null hypothesis is rejected, you publish and continue trying to explain why. Otherwise you stop and try something different.
Films have sold us the idea that science can be done in the countdown of a bomb, experiments take 30 seconds; and if it does not work in the first try, it means that you are not a real genius.

Yeah. Master of disguise. This Big Bird costume pays for itself every time we break into the Pentagon. G'morning Mr Hegseth
But this is a fantasy, not the real life. Scientists stumble and limp all the way. Even the geniuses. Specially the geniuses. And they faint at the price of the required spare part that must be ordered and imported from one, and only one, company in Finland, and will be here in five months. Meanwhile, researchers throw things to the wall to see what sticks, and laser focus on the unexpected strange result that is different in a subtle way, because their grants depend on it.

FYI, your sleep hygiene sounds good, but doctors have started to agree that primary, idiopathic insomnia doesn’t exist. It’s either anxiety or evidence of some severe disease or physiological condition.
So as long as you’re trying things, CBT is the most evidence-based long-term solution for the (very likely) cause of your insomnia.

Not to suggest diagnosis on the internet to people I haven't met, but for me chronic insomnia was actually narcolepsy. Ironic given that it's disease known for excess sleep, but the actual core issue is broken sleep structure. I had actually been supplementing with creatine for the past 6 months or so and recently gave it up. If it was having any effect it was marginal at best. The only thing that works is pharmaceuticals.

I take 5g/day, through better part of last 9-12 months (don't remember when I started).
No noticeable cognitive difference/improvement. And the more I've researched creatine the less convinced I am that there are reliable conclusions about cognitive impacts.
Significant physical changes! But other than the pure aesthetics, it's hard to say that my strength increases are tied to creatine or instead a solid routine, plan, diet, and progressive overload. Probably some all of above.
I also take whey protein isolate (20-25g at least once a day)
The Nootropic space fascinates me. A few observations:
- Not sure if caffeine is considered nootropic. Caffeine definitely makes a difference.
- Unclear if placebo effect or real, L-theanine seems to help with calm and focus.
- Otherwise, when it comes to what I'm sure alters my state/body/etc. - drugs! And I'm not suggesting anything specific but my point is the effects are obvious/real/etc. vs. much of the supplement space that suffers from very murky conclusions (imo).

It's my understanding that creatine doesn't directly make you stronger, instead it gives your muscles the ability to work a bit longer. This means you can do more strength training per session which is the part which makes you stronger.

Feeling like you can confidently take one more rep does feel like being stronger. Sure you're not stronger in the sense that you can lift more weight per rep, but being able to do more heavy reps is also a valid way to define feeling stronger.

icegreentea2 1 days ago [-]
Well, for caffeine you might... at least in the short term.
But to be more specific:
* Protein supplements make it easier for your body to get the protein required for whatever demand you're putting on it. You need higher protein intake to growth than to sustain muscle. If you were on protein supplementation during a growth phase, and then transitioned to a maintain, and stopped supplementing, while making sure your actual diet was sufficient, then you could in principle maintain your muscle mass with no problem. The extrapolation of this is that in principle, you could always replace protein supplements with "real food", regardless of phase and get pretty much the same benefits. There may be lifestyle/ease/cost tradeoffs.
* Creatine supplementation helps your body get "a little extra" work done. The direct boost that creatine grants you is real, but also like... small. I think it's often visualized as "it helps you get that one extra rep/half rep". Where creatine pays off is that by sustainably helping you get that one extra rep, it helps create greater demand on your body over time, therefore promoting more growth. If you stopped creatine supplementation, you would probably lose that "extra rep", but all the extra growth that you got would be locked in.
* Caffeine... well, that's far more psychological. Leaving the world of sports, as a knowledge worker, I've committed myself to my addiction. The withdrawal is real, and even if I worked through the headache, I definitely do not feel as sharp.

I switched from creatine to eating pickled herring or steak instead. It's WAY more expensive, but considering I don't live in a country with very great control over stuff like adulterants, I'll definitely elect for tasty and safe.
Each 2-ounce rollmop contains about a gram or two of creatine, sometimes more. Steak is about a gram per 8 ounces.
If you can afford it, it's way nicer than choking down that powder in water getting all crunchy in your teeth and stuff.
It's decent pre-workout food although not for everyone as mentioned elsewhere in the comments here (Something like 20% of people don't see any workout endurance benefits)

Water that's coming out of your tap is generally aiming for neutral (~7 ph). The alkaline waters in the store are using minerals to elevate it into probably the 9s.

Not really. In the US at least, there’s the “Lead And Copper Rule”, which effectively requires utilities to adjust water composition to make the water minimally corrosive to copper and to lead. This often involves delivering water at a pH higher than 7. (San Francisco, for example, has water pH near 9, although it seems to be on the high end compared to other systems.)

"Creatine found to improve cognitive performance during sleep deprivation" (2024, 56 comments)
"Other studies already proved those effects with creatine with a normal dose schedule, what they were testing is if a single high dose would have a beneficial effect too, which it did.
A normal schedule is 3-5g per day with an optional loading phase of 10-20g per day during 7 days.
In the study they used a single dose of 0.35g/kg which means 20-40g per dose. How do they not get diarrhea? The loading phase is usually split into several doses to avoid diarrhea and I can personally attest to that being a good idea."
What the above doesn't tell you is that taking a loading dose can draw water into your intestines causing diarrhea. You probably can guess how I found this out.

Yes. It’s very rare for a supplement to have such strong and consistent evidence.
A widely-cited review says that short-term supplementation increases maximal power/strength by 5-15%. This in turn may increase the long-term gainz from strength-training exercise. Creatine also increases sprint performance by 1-5%. Though, there seems to be little if any benefit for endurance exercise like long-distance running.
Creatine works because of buffering ATP and creatine kinase.
A problem though is that 1lb of chicken breast contains about 1.5 grams of creatine.
If a person is already eating a modern high protein diet, they are most likely already getting a decent amount of creatine.
I would imagine a vegetarian taking creatine would get a much better effect.

The cited paper in Wikipedia might be accurate and the author is just expecting "at rest" to mean awake but mostly idle. I'd wager that during sleep, we use less than 100W. For the sake of argument if you take out 8 hours (asleep time) from a 24 hour period, you end up with a rate of ~0.8681 grams per second, much closer to 1g/s. Anyway, just a little fun with numbers.

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.

Creatine is a health fad? No other supplement has been this widely-used for such a long time. It was considered safe and effective when I started using it 30 years ago. The benefits are/were well established, the mechanisms well-known, the safety is impeccable. If anything, it's the most well-established supplement on the market - the exact opposite of a fad!

I think another source of variation on the results is the actual nutritional intake of the subjects.
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) ?

The conclusions aren't any different (it's one of the few thing that helps strength, poses no danger to your hair, and almost certainly does nothing for cognition), but the articles at https://www.strongerbyscience.com/?s=creatine are far more comprehensive, including the famous extremely long podcast episodes they used to do.
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.
switchbak 1 days ago [-]
"poses no danger to your hair" I keep hearing folks say this, and even in this thread there's someone who's experienced that and had it stop when they eliminated creatine. I too have experienced exactly that with exactly the stopping of issues once I stopped taking creatine.

I feel like you would need to find some correlation between dosing creatine and increased DHT production to find a link between the two.
Creatine is not an anabolic steroid and does not increase testosterone levels, according to Harvard Health, so while there was 1 suspicious study that claimed that creatine increased DHT, that study has afterwards not been able to be replicated, and since creatine does not manipulate hormones but rather energy instead, it seems to as closes a possible to being a settled fact sans the final nail in the coffin.

> I don’t know. Maybe a little.
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.
“If your experiment needs statistics, you ought to have done a better experiment.” - Ernest Rutherford
So this is more like trying to determine whether ginseng is good at keeping away colds or whatever. Maybe it does (actually quickly searching this, it definitely does but let's pretend it's as folksy as it sounds for a minute) but even if it doesn't then it's harmless and has a bunch of other effects, so when one takes it - the whole possible cold prophylaxis can just be seen as an added perk.
So no, you should not take something merely because it's "probably harmless".
You and I should not. But I'm also not going to bother correcting someneone taking homeopathy for a cold. It doesn't do anything. But unless it contains heavy metals, it also isn't hurting.
When I found ivermectin in my father's fridge, on the other hand, I absolutely asked him what he was taking it for. When I confirmed he's also taking real medicine, I dropped it provided he told his doctor in case there are drug interactions. (There aren't. Ivermectin is pretty safe. That's why the nutters congregate around it.)
The actual things that I now swear by and actually help is consistent sleep of whatever hours that doesn't make you feel sleepy in the day/night (depending on shift) since actual consistency matters more then timing and also in case of workouts really balancing the fatigue to intensity ratio. I understood this late and thought one should always push hard but there needs to be a balance. It's kind of like how cheetah can run really fast but only for 20-30 seconds and then it needs a 30 minute reset period or something. So if you go to failure or always at very high intensity it affects later sets and increases recovery period and in a way driving down overall weekly sets/volume which is main hypertrophy factor.

According to Reddit, Epsom salt has no effect (doesn’t absorb) - you’re wasting your time by using it. They’ll cite all sorts of real, funded studies that agree and yet always the comment section is filled with anecdotal evidence of the contrary - to which a typical response is “hot water in general is soothing” (ignoring efficacy of magnesium sulfate in ice baths).
I digress - creatine is a similar situation. All this confusion at best. It’s also not unlike the health effects of cannabis just prior to going effectively legal - it either causes or cures cancer, or something? We need more research! That’s the real problem!
Any time you see this sort of narrative it’s corporate politics and influence at play.
By virtue of how hard it is to get any information on creatine, it probably threatens some market or vertical at least (whether or not it “works”). Like A. muscaria mushroom or sassafras, you’ll have to do your own research to really know.
"look to the left of you, look to the right of you, one of you isn't real"
What exactly is hard about that? You can get all sorts of information about creatine, it is one of the most studied supplement ever.
What they “doubt” is that it can be absorbed through the skin.
But anyone who takes magnesium tablets can tell you the effect is the same.
And it is studied btw - problem is there are countless on both sides.
Who disputed this?
> What they “doubt” is that it can be absorbed through the skin
The science is helpful. Magnesium sulfate is absorbed less effectively than magnesium chloride. Of course, you're not eating the amount of Epsom salts one dumps in a bath.
> And it is studied btw - problem is there are countless on both sides
This is why meta analysis exists.
Drinking the same Epsom salt in water that you soak in has the same effect as soaking in hot or cold water with it, and it's also the same effect as taking magnesium supplements sold over the counter.
You can try it yourself - totally safe. You already eat magnesium all the time.
Whatever you're doing with your comment, I'm not convinced.
But sure, keep believing they are on your side.
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).
Is discussing such secondary but still highly relevant aspects verboten? Must every comment here be by a lead researcher in the specific field? Would a biomedical science researcher necessarily have any more expertise on these important secondary aspects?
"Trust me, I'm a scientitian". No thanks.
It is a hell of a thing for a random person on an internet forum to be so unilateral, without providing some kind of strong evidence (aside from statements about "the industry", which is kind of beside the point). I would also suggest if you want to be so unequivocal, that the burden of proof is especially high for you.
This "point" isn't actually all that rational - it's knee jerk skepticism. It's a fine default for yourself, but it's not something you get to force on others because they admit there's room for the potential of benefit.
Again: You're perfectly fine to hold that opinion yourself, but when you start trying to force that on others - you now have an especially high bar to reach, and yes - being a lead researcher in the field is exactly what I'm looking for when someone says "X has been proven to not have a benefit for Y".
"Trust me, I'm a scientitian" - Not sure the point of that juvenile wordplay, but Ok: we do have these things called scientists, some are good, some are terrible. You still need to back up your statements - that's the key part, this isn't a blind appeal to authority. And it's a hell of a lot better than "Trust me, I'm a nerd with very strong beliefs about a topic I know very little about".
It'll be people arguing about exact language not being someone's preferred level, or overloading the importance and exact definition of a technical term that experts don't really care about, or blowing up some edge case or another.
That's why I dropped creatine since I didn't notice any benefits when I tried it for a year.
That said it's obviously the right decision to drop it if you're not seeing any effects. The interesting thing about creatine is that people's bodies are very different in their natural levels of creatine, and if you're already at 'saturation' then more creatine isn't going to do anything. Same reason the typical benefits of creatine don't show much difference beyond 5g/day. That's enough to send the overwhelming majority of people towards 'saturation.'
> That's why I dropped creatine since I didn't notice any benefits when I tried it for a year.
Some percentage of people (~20%) are creatine non-responders [1]. It's pretty reasonable to try creatine and then drop it if you find no benefit. I personally find the gain very marginal.

My level at tennis dropped too, but bicycle endurance remained the same.

But speaking of creatine itself, while not inherently toxic, consuming large doses can cause serious indirect harms, such as triggering falsely elevated kidney markers on blood tests that lead doctors to misdiagnose organ failure, unnecessarily cancel crucial medical treatments, or order invasive biopsies. Furthermore, overloading the body with creatine while taking kidney-stressing medications (like heavy doses of ibuprofen) or having an undetected renal condition can cause actual acute kidney strain, while the massive shift of water into muscle cells can trigger severe dehydration, heat exhaustion, and electrolyte imbalances during intense heat or exercise if fluid intake falls behind.
But, I don't want to belabour the point about creatine. Rather, I want to focus on the negatives stemming from NOT doing other things that ARE proven to be safe and effective. People tend to think creatine will solve a lot of their problems (for instance, they may believe it will fix their feeling of being "low energy). But by avoiding things that might actually help their problem get better, they're persisting a poor state of health.
Creatine supplementation not having significant effect in X domain in population level does not mean that it will not have effect on YOU if for example you are vegan and don't get enough creatine from diet. If you have low energy, probably you have something that may not show in a population level. Similarly you may be low in B12 and then B12 can help you, but it may not show effects in population level if most of the population is not low in B12 (and your study is not powered enough to catch nuances).
It is not like when you have to choose between two medicines and excluding one can be harmful even if the other is not harmful to take per se. You can supplement creatine and try whatever else at the same time.
The fact that there's a biologically plausible mechanism plus mixed statistical evidence makes "maybe" a perfectly reasonable conclusion.
I'm sure that the comic wants to be sarcastic but is missing the mark here. This is how science works. Trying and failing every color except green, does not mean that the green experiment has an invalid result.
The author is not understanding that each experiment is independent.
The correct cartoon should show researchers trying green jellybeans 100 times, with 99 negative results and one positive result, and then the press keeping only the positive (Or in this comic, claiming that all jellybeans produce acne).
Mocking the scientific method, and showing scientists as lazy people that play video-games is funny, but is just a cartoon, not the reality. People should not take XKCD as god's speech without any critical thinking. This in your workplace says to me "I don't really understand statistics".
There is an effect that is statistically rare just by chance, AND is consistently absent within a huge control group of "non-green jellybeans" (the author seems to think that this weakens the result, but in fact is reinforcing it). And it needs further research. Not less, not more.
You could have skipped the wall of text. They didn’t find a link. They found a random correlation.
The scientists here essentially engaged in P-hacking: https://en.wikipedia.org/wiki/Data_dredging
Munroe didn’t misunderstand the independence of the experiments at all. He understands that misleading spurious results can arise from repeated experiments.
> And it needs further research. Not less, not more.
No it doesn’t. At least not anymore than the other colors. A positive result is no more deserving of further investigation than a negative result. What you are describing is bad science.
> A positive result is no more deserving of further investigation than a negative result.
This is not how science works.
Your null hypothesis is rejected, you publish and continue trying to explain why. Otherwise you stop and try something different.
Films have sold us the idea that science can be done in the countdown of a bomb, experiments take 30 seconds; and if it does not work in the first try, it means that you are not a real genius. The weird guys build a time machine in a weekend with empty cans of soda, and the hackers broke into high security buildings with a paperclip and then remove their glasses and nobody recognizes then anymore. Yeah. Master of disguise. This Big Bird costume pays for itself every time we break into the Pentagon. G'morning Mr Hegseth
But this is a fantasy, not the real life. Scientists stumble and limp all the way. Even the geniuses. Specially the geniuses. And they faint at the price of the required spare part that must be ordered and imported from one, and only one, company in Finland, and will be here in five months. Meanwhile, researchers throw things to the wall to see what sticks, and laser focus on the unexpected strange result that is different in a subtle way, because their grants depend on it.
They ran the same experiment 20 times with a meaningless variable changed until they got a positive result with a confidence of 95%. (i.e. 1/20 chance of a random positive result.)
The point of the comic is that this is bad science. Or at least it is ver bad science reporting. This kind of nonsense is why there is a multibillion dollar market for supplements that do not hold up to further testing.
> This is not how science works in the real life.
True. There is a lot of bad science in real life.
“There's a sucker born every minute.”
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.

You also seem to reject the possibility that some things help just a bit. The author has another article in the same vein about "things that can help maybe a bit but the evidence we have doesn't really help detecting small effects" https://dynomight.net/vitamin-d/
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?"

I'm reminded of something I read about dual n-back. (I forget where, it might have been Gwern page on it.) Someone said that when they are sleep deprived, they feel totally fine, but their n-back score absolutely tanks.
It might be interesting to test that, the intersection of sleep deprivation, creatine and objective measures of executive function. That could give us more data on the "helps most in stressed cases" theory.
So as long as you’re trying things, CBT is the most evidence-based long-term solution for the (very likely) cause of your insomnia.
No noticeable cognitive difference/improvement. And the more I've researched creatine the less convinced I am that there are reliable conclusions about cognitive impacts.
Significant physical changes! But other than the pure aesthetics, it's hard to say that my strength increases are tied to creatine or instead a solid routine, plan, diet, and progressive overload. Probably some all of above.
I also take whey protein isolate (20-25g at least once a day)
The Nootropic space fascinates me. A few observations:
- Not sure if caffeine is considered nootropic. Caffeine definitely makes a difference.
- Unclear if placebo effect or real, L-theanine seems to help with calm and focus.
- Otherwise, when it comes to what I'm sure alters my state/body/etc. - drugs! And I'm not suggesting anything specific but my point is the effects are obvious/real/etc. vs. much of the supplement space that suffers from very murky conclusions (imo).
And protein is just convenient way to hit daily protein intake goals for someone doing lots of sports.
No. They're not steroids.
But to be more specific:
* Protein supplements make it easier for your body to get the protein required for whatever demand you're putting on it. You need higher protein intake to growth than to sustain muscle. If you were on protein supplementation during a growth phase, and then transitioned to a maintain, and stopped supplementing, while making sure your actual diet was sufficient, then you could in principle maintain your muscle mass with no problem. The extrapolation of this is that in principle, you could always replace protein supplements with "real food", regardless of phase and get pretty much the same benefits. There may be lifestyle/ease/cost tradeoffs.
* Creatine supplementation helps your body get "a little extra" work done. The direct boost that creatine grants you is real, but also like... small. I think it's often visualized as "it helps you get that one extra rep/half rep". Where creatine pays off is that by sustainably helping you get that one extra rep, it helps create greater demand on your body over time, therefore promoting more growth. If you stopped creatine supplementation, you would probably lose that "extra rep", but all the extra growth that you got would be locked in.
* Caffeine... well, that's far more psychological. Leaving the world of sports, as a knowledge worker, I've committed myself to my addiction. The withdrawal is real, and even if I worked through the headache, I definitely do not feel as sharp.
Each 2-ounce rollmop contains about a gram or two of creatine, sometimes more. Steak is about a gram per 8 ounces.
If you can afford it, it's way nicer than choking down that powder in water getting all crunchy in your teeth and stuff.
It's decent pre-workout food although not for everyone as mentioned elsewhere in the comments here (Something like 20% of people don't see any workout endurance benefits)
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.
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.

Similarly you fail to account for anyone who takes creatine with any other food or beverage.

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.
How old are you?
Also, working out helps reduce stress. Does it seem more plausible that getting lazier on your workouts, rather than the creatine, increased stress in your life, thus the hair thinning?
I have never heard of creatine causing thinning hair.
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.
Like many hippie health trends that then go mainstream, a lot of it seems to filter in from Rastafarian traditions, where in the Ital diet they believe that alkaline water coming from the Blue Mountains in Jamaica (and other natural springs there which are naturally alkaline) help detoxify the acids in the body.
Not really. In the US at least, there’s the “Lead And Copper Rule”, which effectively requires utilities to adjust water composition to make the water minimally corrosive to copper and to lead. This often involves delivering water at a pH higher than 7. (San Francisco, for example, has water pH near 9, although it seems to be on the high end compared to other systems.)
$50 for flavoured salt is pure insanity.
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.
At a certain point I was wondering if it was just placebo, stopped taking it for a month or so, and was quickly back to feeling tired after training. Started taking it again, back to feeling energized. It really does work.

"Other studies already proved those effects with creatine with a normal dose schedule, what they were testing is if a single high dose would have a beneficial effect too, which it did. A normal schedule is 3-5g per day with an optional loading phase of 10-20g per day during 7 days.
In the study they used a single dose of 0.35g/kg which means 20-40g per dose. How do they not get diarrhea? The loading phase is usually split into several doses to avoid diarrhea and I can personally attest to that being a good idea."
What the above doesn't tell you is that taking a loading dose can draw water into your intestines causing diarrhea. You probably can guess how I found this out.
If you can say "Oh yea that makes sense" with the same set of knowledge you had both before and after some event happens, all else being equal, you have an expectation. That is enough for placebo.
You have to have literally 0 knowledge about an event to rule out placebo.
I drink lots of water. Lots and lots, to the point that it’s already kind of annoying how frequently I have to piss. I’m fairly skeptical that drinking yet more would yield any benefits.
Yes. It’s very rare for a supplement to have such strong and consistent evidence.
A widely-cited review says that short-term supplementation increases maximal power/strength by 5-15%. This in turn may increase the long-term gainz from strength-training exercise. Creatine also increases sprint performance by 1-5%. Though, there seems to be little if any benefit for endurance exercise like long-distance running.

Creatine works because of buffering ATP and creatine kinase.
A problem though is that 1lb of chicken breast contains about 1.5 grams of creatine.
If a person is already eating a modern high protein diet, they are most likely already getting a decent amount of creatine.
I would imagine a vegetarian taking creatine would get a much better effect.
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.
Also search for 'sleep' in this comment section, seems many see similar improvements!
If the cognitive effects are real, they aren’t noticeable to me without placebo effect. Meaning, I hadn’t heard any notion of creatine impacting cognitive function and I’ve been taking it on and off for years, and never noticed anything.
Thinking back, maybe an uptick in mood and a mental performance while tired? Purely unscientific, though.
I’ve researched it quite a bit and found that others do experience it as well, but the usual advice of “just drink more water” (which yes, I have tried) is about the extent of info I find on it. Then, the “it causes your body to retain more water” idea which doesn’t seem to be accurate as what I’ve understood is that it causes your muscles to store more water…
The cited paper in Wikipedia might be accurate and the author is just expecting "at rest" to mean awake but mostly idle. I'd wager that during sleep, we use less than 100W. For the sake of argument if you take out 8 hours (asleep time) from a 24 hour period, you end up with a rate of ~0.8681 grams per second, much closer to 1g/s. Anyway, just a little fun with numbers.
Like being tired, stressed, etc...
Here are the sleep deprivation studies

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.
Well, yes. It is well known that you must eat fish, beef, i.e., animal protein, to get close to optimal levels of creatine.
It could be underlying genetic predisposition to hair loss, but I do believe the creatine had an accelerating effect. When I stopped taking creatine, the rate of hair loss noticeably slowed down throughout the rest of my 20s.
Although OP's post says "There is no mechanistic reason to think that would happen." but I don't think that's true. Creatine is known to increase DHT, and higher levels of DHT is linked to hair loss.
Is creatine safe to supplement for children?
It’s just resurfacing as a general health fad/marketing campaign.
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) ?
Meat Is Murder but Fish Is Justifiable Homicide.

Why is "gains" spelled this way? I found myself suddenly trusting the whole thing a little less. But maybe I'm missing something. Is this jargon in the body building world or something? Author being cheeky?
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.
It was always start by 'loading' and then cruise at 5g. Of course GNC was filled with sugar filled "delivery" products like Celltech that claimed to forego any need for 'loading'.
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?

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.
Just curious for other folks experiences as they are on or off creatine in parallel with other hair interventions.
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.
Last I checked, the only study actually focusing on this is n=38, out of Iran, and has heavy conflict of interest issues (funded by the supplement industry).
That's not remotely sufficient to consider this a settled fact.
Creatine is not an anabolic steroid and does not increase testosterone levels, according to Harvard Health, so while there was 1 suspicious study that claimed that creatine increased DHT, that study has afterwards not been able to be replicated, and since creatine does not manipulate hormones but rather energy instead, it seems to as closes a possible to being a settled fact sans the final nail in the coffin.
It safely builds muscle and boosts cognition.
More like "probably", "yes", and "probably not."
