I don’t understand the author’s reading of the literature they cite. They refer to “isolated studies” and then link to a systematic review of 25 studies. They also linked to the same review twice for both memory and attention, which I assume is a mistake, because the review only supports the claim about memory.
But none of these studies are about “brain-boosting”. They’re about preventing or reversing cognitive decline, which is perhaps related, but ultimately different.
No fault to the author of this post for being unable to find evidence focused on healthy adults; anyone who has looked into the evidence around nootropics can tell you that pretty much nobody wants to study that. But it’s important to be clear about what the evidence actually says, and what it doesn’t speak to.
