Not just vegetarians; if you had clicked through to my page, you’d see my summary:
however, Rae 2003 was only in vegetarians, who are known to be creatine deficient (much like B vitamins, creatine is usually gotten in one’s diet from meat), and the other studies are likewise of subpopulations. Rawson 2008 (PDF) studied young omnivores who are not sleep-deprived, and found no mental benefits. However, vegetarians (Rae 2003), the sleep-deprived, and old people may benefit from creatine supplementation.
I did click through to your page; I decided not to quote it directly, which was a mistake. My impression is that of LWers, vegetarians are the most common group (though perhaps there are lots of sleep-deprived people).
Overall, I was disappointed with taking a qualified statement (“creatine deficiency causes intelligence problems; make sure you have enough”) and turning it into an unqualified statement (“creatine improves cognitive performance”).
My impression is that of LWers, vegetarians are the most common group (though perhaps there are lots of sleep-deprived people).
But still not very common. Vegetarian LWers would be, what, 10% maybe? (Not sure any surveys have covered it, but I don’t see it discussed very often).
Overall, I was disappointed with taking a qualified statement

That’s Luke’s description, not mine. I’ve edited the page to include specific citations for each group and some PDF links, incidentally.
Isn’t this primarily true for vegetarians? I was under the impression that most people have all the creatine their brains can make use of.
