Nootropics Limited evidence

Ginkgo Biloba

The old memory tree with mixed modern trials.

Ginkgo is the original drugstore brain pill. Standardized EGb 761-type extracts have the data; random leaf powder does not. Effects on healthy young memory are underwhelming. Blood-thinning interactions are the adult conversation.

How to use

120–240 mg standardized extract with food, consistently for 8+ weeks.

Legacy nootropic. Fine as a trial in older adults; skip it next to anticoagulants without a clinician.
