UnprovenWidely claimed, not demonstrated.
Kept separate from the priority score on purpose: confidence in the evidence never raises how worth-it something is.
What we read
- Modafinil and methylphenidate for neuroenhancement in healthy individuals: A systematic review
Pharmacological Research · 2010
Expectations outran effects: methylphenidate improved memory and little else; modafinil helped attention when people were rested and wakefulness when they were sleep-deprived — smaller gains than the marketing.
- Ginkgo for Memory Enhancement: A Randomized Controlled Trial
JAMA · 2002
In 230 healthy adults over 60, six weeks of ginkgo (40 mg three times a day) did not improve any of the memory, attention, or concentration tests versus placebo.

Where this falls down
Still unknown. Caffeine is a real nootropic and is not what this card is scoring; the proprietary blends, racetams, and herb stacks sold as 'smart drugs' are.
