Unfortunately, I get terribly tired and brain-fogged from even small quantities. Anyone else experienced this?

I haven't heard of that but I know creatine causes loads of water absorption. I wonder if you're borderline dehydrated and creatine pushes you over the limit.

The water retention can be avoided with low-dose creatine which still has some benefits in studies

Instead of 5grams/day like 2grams/day

You can also spread it out during the day to avoid retention, 1000mg x 4 or x 2

Creatine is also a precursor to SAM-e which is a natural antidepresant

The article's entirely AI-generated; not necessarily untrue but may not have been fully reviewed by an editor.

What did you use to determine this?

Ask because many of the online tools I've tried, they will sometimes tag what I've written at 30-40% AI written and sometimes purely AI written stuff is flagged as 60-70% AI

Feels like a sign of the times that I expect half the comments here to be paid astroturfing about how amazing creatine is.

Creatine is $10 at Walmart, I don't think they are paying for astroturfing. It's a chemical like salt.

That strikes me as a really poorly calibrated expectation. Who benefits? Who's paying? How could I get this job?

Creatine is one of the few supplements I actually notice a difference if I quit taking. Happy to see it’s benefits extend to beyond performance in the gym.

Funny because I'm not sure I quite notice it immediately when I stop taking it, presumably since the body retains a certain amount of it. But I definitely notice a difference when taking it the first day after not having had it a little while, especially when taking 20+ grams a day. It gives me so much mental energy and alertness that I won't get a whole lot of sleep, but the next day I end up feeling just fine. If I remember correctly, there have been at least 2 studies that suggested high doses of creatine reduce the side effects of suboptimal sleep, and that definitely seems to be the case in my experience.

I feel like crap when taking creatine... Actually most of these purported supplements are a no go. Preworkouts would work first session then make me ultra tired, caffeine is fine as long as I 'cycle' it... Wondering strongly if those studies are not just to sell more cheap supplements... As long as for some reason we find that it has some level of effect on most people. It has some effect for sure but not sure it is…

Try micronised (even finer powder, maxxwell has them) or even in jelly gummy form.

I take 7.5 g every day for a couple of years now and what I definitely noticed is much lower sugar cravings during hard programming days: previously I would eat almost one chocolate every day.

Though YMMV, as I also bench press 140 kg.

Direct link to the study: https://jpbs.hapres.com/htmls/JPBS_1766_Detail.html I wanted to check the dosages they used. Looks like the review includes studies ranging from 5g/day to 20-25g/day. (Typical dosage you'll see for daily use is 5 grams)

I use it as a supplement because I do weightlifting. 5g/day. I did 20g/day for a week once, and didn't notice it made any difference, so I'm back to 5g now. In terms of stuff like memory, mood, etc. I can't say it's made any improvement but the idea that it might be helping prevent decline is nice.

Be sure it’s pure creatine, they often mix in all kinds of shit. I take creapure just to be sure.

Just buy 95% creatine monohydrate. This is the most common formulation, but others do exist.
