There was that RCT showing that creatine supplementation boosted the IQs of only vegetarians.
My understanding is that the most rigorous RCT on creatine for cognitive performance found no difference between vegetarians and meat eaters and virtually no effect size in either case.
It looks like creatine supplementation does mildly affect cognitive performance but it doesn’t help vegetarians more than omnivores.
But isn’t creatine really hard or impossible to get with a vegan diet? So presumably then it would be affecting their regular cognitive performances?
This study shows that supplementing causes a similar increase of cognitive abilities compared to omnivores, but it could be that they’re starting from a worse spot than they would have been had they been omnivores?
It’ll be hard to figure that out because vegetarians tend to have baseline higher IQs, from what I recall. But that is quite likely a selection effect.

Ooh, thanks for tracking this down!
