Although the evidence isn't consistent across studies, or tests within studies, Bacopa appears to enhance various sorts of memory (notably working memory) in both healthy persons and through cognitive decline. It's unclear what effects it's within the long-term, as most studies are either 12 weeks long or affect acute dosing, the previous being more reliable. More high-quality evidence and replication of specific tests is required before we will be confident in its effects.
There appear to be attention promoting effects of CDP-Choline, with the one study in adult women noting that 250-500mg was effective but 250mg was simpler.
Attentional focus and similar parameters (task switching) don't appear to be significantly influenced by ginkgo supplementation.
The ability to enhance performance on some mental tasks that need a high degree of attention has been noted with acute dosing, but it doesn't seem to be particularly consistent. Little evidence exists for long-term effects, and therefore the main study that evaluated them could are observing the consequences of improved sleep quality instead of anything inherent to theanine.
