>> Recently, a pilot study (single-arm) by Smith et al., recruited 20 patients (73 years of age) with AD and provided them with 20 grams/day of CrM for 8 weeks [20]. Serum creatine levels were increased at weeks 4 and 8 (p < 0.001), and total brain creatine levels (as measured by H-MRS) increased by 11% (p < 0.001). Clinically, there were demonstrated improvements in cognition on global (p = 0.02) and fluid composites (p = 0.004), as well as List Sorting (p = 0.001), Oral Reading (p < 0.001) and Flanker tests (p = 0.05).
Yeah 20 patients is not a lot. I'm inferring this is a pre-post test. However some of those p-values are pretty good (.001 on reading and and sorting). Very promising pilot study but not conclusive imo.
tgv 11 minutes ago [-]
19 patients completed, according to the article.
And List Sorting, Oral reading, and Flanker only? The first and last are part of global and fluid composites, so those have to be excluded from comparison. That leaves us with 3 improved scores out of 12 tests. So 9 did not improve, or got worse. Figure 3 (of the original article) shows that the changes aren't big. Just "significant". Since the participants were in the early stages of dementia, this seems well within expectations.
So I can't see those numbers as impressive.

Sounds like something we should study more rather than dismiss.
I wanted to check the dosages they used. Looks like the review includes studies ranging from 5g/day to 20-25g/day.

High dosage is not for your daily intake
It’s called loading phase to quickly saturate the tissues
I wouldn’t go higher than 10g daily on a regular basis.
I personally take 7,5g for the last couple of years.
gardnr 33 minutes ago [-]
Just in case anyone is thinking about trying it: 25g seems pretty high. It’s worth it to review what that means for the rest of your body before starting this regime. Kidneys are really useful organs to have working.
ai_fry_ur_brain 24 minutes ago [-]
This is a myth, its not bad for your kidneys. The reason this gets spread is because you will have higher levels of creatine in your urine if your Doctor tests your urine for kidney function, which indicates kidney disease.
However, If you reveal to that doctor that you're supplementing Creatine it will not be concern them.

I think male baldness is a bit more complex than creatine->DHT->loss of hair.
But if you want to go down that road, there's also indications that the oil in pumpkin seeds reduce the enzymatic process that turns testosterone into DHT - so just eat some pumpkin seeds with your creatine and the problem goes away! It's that simple!!!

A few thoughts
1) It annoys me whenever anybody mentions literally anything (whatever baking soda, potassium, any vitamin) you get a million unhinged comments about how this was a personal panacea.
2) Creatine definitely does stuff, that's scientifically been established by numerous studies for decades. It's been recommended as a supplement for vegetarians for mental reasons and for people trying to build muscle-mass (sort of niche). I'm actually a bit surprised how few people talk about it when it's a standard blood test thing (possibly because it can't be patented).
3) It's dirt cheap and made by tons of difference places. I don't think there's a "big creatine." It's probably like < 25 cents a serving.
That strikes me as a really poorly calibrated expectation. Who benefits? Who's paying? How could I get this job?

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.

Silagi 8 minutes ago [-]
Are you increasing your water intake when you do? That sounds like dehydration. Creatine takes a large amount of water to appropriately process, and during the loading phase, your body is pushing substantially more water into your muscles. Anecdotally, if I don't drink something like an extra half gallon of water a day while loading at 15g/day, I show symptoms of dehydration. And I'm already drinking somewhere between a half gallon to a gallon a day.
willy_k 13 minutes ago [-]
Yes I can definitely “feel” it when I take it, especially so at 10g+. And it makes me overly reactive and somewhat irritable, and gives me a ton of energy that needs to be let out lest the former two get worse.

stouset 40 minutes ago [-]
It’s a flavorless powder you mix into a drink. It unfortunately doesn’t really dissolve, so it can be a little grainy if taken with water but it’s mostly flavorless so outside of that you wouldn’t notice it.
5g/day is the general recommendation and most packaging will come with an appropriately sized scoop, notably this is one of the rare ones where dose doesn’t seem to be adjusted by age or bodyweight. I presume because it’s cheap, well-studied, and there don’t appear to be downsides for overdoing it. They’re testing it at up to and possibly above 25g/day for Alzheimer’s.
Some people recommend a higher “loading” dose for the first two weeks to build up reserves in your body more quickly, but if the goal is to start taking it daily, this is really unnecessary.
ravenstine 33 minutes ago [-]
> there don’t appear to be downsides for overdoing it
There may or may not be a downside depending on what one considers a downside.
In one of my other comments I just made in this thread, I mentioned my experience taking relatively large doses of 20g a day. While I found it has cognitive benefits, it did interfere with my sleep, though not catastrophically. If a person happens to enjoy sleep, then it's probably best they stick to 5 or 10 grams. On the other hand, if you need to pull an all-nighter, the sleep interference (as well as the better recovery the following day) may not be seen as a downside but beneficial.
But yeah, from a toxicological perspective, creatine does seem very safe even at those doses.
stouset 25 minutes ago [-]
Yes, there is always going to be someone somewhere that sees some sort of issue. My point wasn’t that nobody anywhere has ever experienced a negative consequence, but that at scale, it is overwhelmingly safe and so it isn’t really worth advising the general public to tailor their dose.
Any of the rare issues that people do experience—especially at the 5g/day level across age and weight—are minor, acute, and easy to resolve by simply lowering the dose.

As for a second dose, that's of possible value for intense exercise, but again be mindful of insomnia.

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 that positive...
Besides, I don't know if it helped jump start the process or not but I build muscle either way, on little protein, no creatine... Carbs seem to be more important actually.

In my experience, those with creatine intolerance, especially if assuming it's not taken late in the day, have unresolved excitotoxicty/inflammation/pressure/headache/migraine issues in their brain.
Also, be mindful with blends as they can be fairly dangerous. It's best to get an isolated creatine monohydrate product that is not a blend.
Check your blood pressure. It is very possible that there is something else in your blend that is raising your BP.
I have the same struggles with preworkout, they are just overkill for me and make me crash and i feel they impact my sleep because i usually work out at a random time so the caffeine timing may be terrible. Certainly had success with them for a while, but it was when i didn't really care when i went to sleep because when i was younger I'd just sleep for 8-10 hours straight regardless of time of day/night.
