Aniracetam
Aniracetam
Aniracetam is a fat-soluble racetam nootropic developed in the 1970s, primarily used to enhance cognition, reduce anxiety, and improve mood. It is prescribed in Europe and Japan for cognitive decline and dementia, while commonly used off-label worldwide as a cognitive enhancer and anxiolytic. It is notable among racetams for its combined nootropic and anxiolytic properties.
Mechanism of Action
Aniracetam acts as a positive allosteric modulator of AMPA receptors, slowing receptor desensitization and enhancing glutamatergic neurotransmission, which supports learning and memory consolidation. It also stimulates metabotropic glutamate receptors (mGluR1 and mGluR5) and increases acetylcholine release in cortical and hippocampal regions. Additionally, it modulates dopamine and serotonin receptor activity in the mesolimbic system, which is believed to underlie its anxiolytic and mood-enhancing effects.

Dosing Protocols
With meals containing dietary fat to enhance absorption
Cycle: 4-8 weeks on, 2-4 weeks off
Most commonly dosed at 750mg twice daily (1500mg total). Fat-soluble compound requiring dietary fat for adequate absorption. Often stacked with a choline source such as Alpha-GPC or CDP-choline to prevent headaches and support acetylcholine synthesis.
Safety & Side Effects
Aniracetam has a generally favorable safety profile in human studies, with no significant toxicity observed at typical doses; it is prescription-approved in several European countries and Japan. However, it is unscheduled but unregulated as a supplement in the US and many other countries, long-term safety data in healthy adults is limited, and quality control varies significantly among grey-market suppliers.
Possible Side Effects
- !Headaches, especially without adequate choline supplementation
- !Mild anxiety or irritability at higher doses
- !Nausea or gastrointestinal discomfort, particularly on an empty stomach
- !Fatigue or mental fogginess in some users
- !Insomnia or sleep disturbances if taken late in the day
- !Mild skin rash or flushing in sensitive individuals
- !Vivid dreams or altered dream states
Interactions
- -May enhance the cognitive effects of other racetams (piracetam, oxiracetam) — combination may increase headache risk without sufficient choline
- -Potential additive CNS depression with benzodiazepines, alcohol, or sedative medications — use with caution
- -May potentiate the effects of cholinergic drugs or acetylcholinesterase inhibitors such as donepezil, risking cholinergic excess
- -Theoretically may interact with stimulants such as amphetamines or modafinil — monitor for increased cardiovascular effects
- -May have additive anxiolytic effects with other GABAergic or serotonergic supplements — use caution with high-dose L-theanine or 5-HTP combinations
Cost & Where to Buy
Bulk powder is significantly cheaper than capsules; price varies by vendor purity and form. Quality third-party tested sources cost more but are recommended given the unregulated supplement market.
