What is Oxiracetam?
Oxiracetam is a synthetic racetam developed in the late 1970s and obtained by adding a hydroxyl (-OH) group to the structure of piracetam. The compound, whose chemical name is 4-hydroxy-2-oxo-1-pyrrolidinacetamide, is a cyclic GABA derivative, like other members of the racetam family; however, it does not act directly on GABA receptors.
User experiences and limited clinical literature make oxiracetam particularly logical-analytical thinking, associates it with attention and processing speed. For this reason, it is often described as a molecule with a "technical/analytical focus" profile within the racetam family.
Its Place in the Racetam Family
Its place in the Racetam family: Piracetam is a balanced and mild basic molecule, while oxiracetam is more stimulating and speed-oriented; Aniracetam, on the other hand, is fat-soluble, anxiolytic, and prone to creativity. All three benefit from choline synergy.
Mechanism of Effect
The effects of oxiracetam are mainly expressed through two glutamatergic pathways:
1. AMPA and NMDA Receptor Modulation
Oxiracetam supports long-term potentiation (LTP) by positively affecting both AMPA and NMDA receptor activity in the glutamatergic system. This modulation is a mechanism thought to strengthen the molecular basis of learning and memory consolidation.
2. Effect on the Cholinergic System
Like other racetams, oxiracetam stimulates the acetylcholine cycle and increases choline utilization. Therefore, headaches may occur with insufficient choline intake; Concomitant use with Alpha-GPC or CDP-Choline reduces this risk.
3. Cerebral Metabolism
Limited studies indicate that oxiracetam supports cerebral glucose metabolism and blood flow; however, these findings are predominantly in the context of age-related cognitive decline, and evidence is limited in healthy young individuals.
Clinical Evidence
Most studies on oxiracetam were conducted in the 1980s and 1990s, predominantly in age-related cognitive impairment and dementia populations. These studies reported improvements in measures of attention and memory compared to placebo. However, samples are small, method quality is variable, and solid evidence for use for cognitive enhancement in healthy individuals is limited.
⚠ Limitation of Evidence
Limitation of evidence: High-quality, modern randomized studies demonstrating the effectiveness of oxiracetam in healthy young individuals are scarce. Available data rely heavily on clinical populations and older studies; Therefore, expectations should be kept cautious.
Dosage and Usage Protocol
| target | Daily Dose | How to Use | Note |
|---|---|---|---|
| Start (tolerance test) | 800 mg/day | Single dose, morning | First 1–2 weeks |
| cognitive support | 1200–1600 mg/day | 2× divided dose | Most common range |
| high dose | 2400 mg/day | 2–3× divided dose | Choline support is a must |
Oxiracetam is water soluble and due to its mild stimulant effect it is usually morning and noon It is recommended to take it and not to use it late in the evening. Since its half-life is approximately 8 hours, two daily doses are suitable for most users.
- Alpha-GPC: 300–600 mg/day (high BBB permeability, preferred source of choline)
- CDP-Choline (Citicoline): 250–500 mg/day (adds dopaminergic synergy)
Safety and Side Effects
Oxiracetam is generally considered a well-tolerated, low-toxicity compound. Reported side effects are generally mild and temporary.
| Possible Impact | frequency | Management |
|---|---|---|
| headache | Common (in choline deficiency) | Add choline source |
| Restlessness/trouble sleeping | rare | Avoid evening dose |
| stomach upset | rare | Take with food |
⚠ Legal Status
Legal status: Oxiracetam is not licensed as a food supplement in many countries, including Türkiye, and is in the regulatory gray area. It is recommended that you consult current legislation and a physician's opinion before use. This content does not constitute medical advice.
Is Oxiracetam Legal in Türkiye?
Oxiracetam is not licensed as a food supplement in Türkiye and is not included as a standard in the pharmacy prescription drug catalogue. Foreign sourced raw material forms are in a legally uncertain area. It is recommended that those considering using it consult a neurologist or physician.

Frequently Asked Questions
Oxiracetam is a synthetic racetam that is the hydroxyl derivative of piracetam. It is reported to support attention, logical-analytical thinking, and processing speed by modulating AMPA and NMDA receptors and supporting the cholinergic system. It is a mildly stimulating, speed-oriented member of the Rasetam family.
The common range of use is 1200–2400 mg per day, in divided doses. Because it increases choline utilization, it is often recommended to take it with a choline source such as Alpha-GPC or CDP-Choline to reduce headaches.
Due to its mild stimulant effect, it is recommended to take it in the morning and at noon and not to use it late in the evening. Since its half-life is approximately 8 hours, two daily doses are suitable for most users.
Oxiracetam is not licensed as a food supplement in Türkiye and is in a regulatory gray area. As its legal status is unclear, current legislation and a healthcare professional should be consulted before use.
Oxiracetam is considered more stimulant and speed/logic oriented than piracetam; Piracetam, on the other hand, is a more balanced and mild basic molecule. Both benefit from choline synergy, but oxiracetam has a longer half-life.
