Aniracetam

non-nutrient/non-botanical

What is it

Aniracetam is a synthetic compound in the racetam family of cognitive-enhancing drugs (nootropics). It is a prescription medication in some European countries for cognitive impairment and dementia, but is unregulated and sold as a research chemical or supplement in the United States, where it does not meet criteria as a dietary supplement ingredient.

How it works

Aniracetam is a positive allosteric modulator of AMPA glutamate receptors, the main excitatory receptors in the brain. By slowing receptor desensitization, it enhances glutamatergic signaling, which is involved in learning, memory, and synaptic plasticity. Aniracetam may also modulate acetylcholine and dopamine release in certain brain regions. It is fat-soluble (unlike water-soluble piracetam) and rapidly absorbed when taken with fat, with a relatively short half-life (1-2 hours). Most of the parent compound is metabolized to anisoyl-GABA, which may contribute anxiolytic effects. Clinical studies in Europe have focused on cognitive impairment in elderly patients; data in healthy adults are limited.

Evidence for 4 uses

AI-assisted evidence assessment — talk to your doctor before relying on any single supplement.

Cognitive impairment in elderly (European clinical use)

Grade C

Moderate evidence

Aniracetam is approved in some European countries for age-related cognitive decline. Trials suggest modest improvements in memory and behavioral measures, but methodology and outcomes vary.

Stroke recovery / cerebrovascular disease

Grade C

Moderate evidence

Small European trials have used aniracetam for cognitive recovery after stroke. Evidence is modest and not widely replicated outside specific clinical settings.

Memory and learning in healthy adults

Grade F

Limited evidence

Despite its popularity as a nootropic, controlled trials of aniracetam in healthy adults are sparse. Effects on cognitive performance in non-impaired individuals are uncertain.

Anxiety / mood

Grade F

Limited evidence

Anxiolytic effects in animal studies and self-reports exist, but human trials specifically for anxiety are limited and inconclusive.

2 commercial forms

Aniracetam powder

Fat-soluble; absorption improved with fat-containing meal

Common in supplement form; can be measured to precise doses but has a bitter taste.

Aniracetam capsules

Same absorption profile

Pre-measured for convenience; still benefits from co-administration with fat.

Dosage

Studies have used 1000-1500 mg per day, often divided into two or three doses. Supplement labels typically list 750-1500 mg per serving. Because aniracetam is fat-soluble, it is often recommended to take with a meal or source of fat.

When and how to take it

Take with a meal containing some fat to enhance absorption (aniracetam is fat-soluble). Doses are typically split between morning and afternoon to maintain effects throughout the day. Avoid evening doses if you experience sleep disturbance. Some users co-supplement choline (e.g., alpha-GPC or CDP-choline) to reduce headache risk.

Safety

Generally well tolerated in clinical studies. Common side effects include headache, anxiety or restlessness, insomnia, and gastrointestinal upset. Some users report low-mood or fatigue effects. Long-term safety data outside of European clinical use are limited. Quality of supplement-grade aniracetam can be inconsistent.

Who should be cautious

Avoid in pregnancy and breastfeeding. People with liver or kidney disease should consult a clinician. Those with seizure disorders, psychiatric conditions, or taking psychiatric medications should be cautious. In the US, the FDA has stated that aniracetam does not qualify as a dietary supplement ingredient.

Interactions

Aniracetam may interact with cholinergic medications (acetylcholinesterase inhibitors), other nootropics (especially other racetams), CNS depressants, and antidepressants (particularly those affecting glutamate or serotonin). Choline supplementation is sometimes co-administered to prevent headaches.

Frequently asked questions

Is aniracetam legal?⌄

It varies by country. In some European countries it is a prescription medication. In the US, the FDA does not recognize it as a dietary supplement ingredient, so its sale as a supplement is technically not permitted, though it is widely available online.

Does aniracetam actually improve memory?⌄

Evidence for cognitive enhancement in healthy people is weak. Most clinical studies are in elderly patients with cognitive impairment, where modest benefits have been reported.

Why take choline with aniracetam?⌄

Aniracetam may increase acetylcholine demand. Co-supplementing with choline sources like alpha-GPC or CDP-choline is widely reported to reduce racetam-related headaches.

How does aniracetam differ from piracetam?⌄

Aniracetam is fat-soluble (piracetam is water-soluble), has a shorter half-life, and is generally considered to have stronger anxiolytic effects and weaker memory effects than piracetam.

Are there long-term risks?⌄

Long-term safety data are limited, especially in healthy users. Caution and periodic breaks are reasonable for chronic use.
