Quick Take

Skip for healthy adults; weak evidence for cognitive enhancement and not approved as a dietary supplement in the US.

Piracetam is a synthetic GABA-derived compound developed in the 1960s as the prototypical nootropic; it does not occur in food. It is thought to modulate AMPA-receptor neurotransmission and improve neuronal membrane fluidity. Clinical trials show inconsistent, modest benefits for age-related cognitive decline and post-stroke aphasia, while evidence for memory enhancement in healthy adults remains weak. It is most often considered by older adults with mild cognitive impairment, though it is not approved as a dietary supplement in the United States.

Potential benefits

01
May improve cognition in age-relate
02
May aid post-stroke aphasia recover
03
May improve reading in dyslexia
04
May enhance memory in healthy adult

Protocol

Amount
2400-4800 mg
Frequency
Split into 2-3 doses throughout the day
When
With meals to minimize gastrointestinal discomfort.

Onset Time

4-12 weeks for cognitive effects in older adults; acute effects in healthy.

Who Should Consider

Older adults with mild cognitive impairment
Stroke survivors with aphasia (under medical supervision)
Adults interested in experimental nootropics with tempered

How It Works

Piracetam positively allosterically modulates AMPA receptors, facilitating cholinergic neurotransmission. It also appears to increase membrane fluidity in erythrocytes and neurons and may enhance mitochondrial function and cerebral glucose metabolism without direct sedative or stimulant activity.
