What is Coluracetam?
Coluracetam was initially developed by Mitsubishi Tanabe Pharma in Japan. It was first explored as a treatment for Alzheimer’s disease, and later gained attention for its role in managing major depressive disorder and generalized anxiety disorder. Over time, it has made its space in the world of cognitive enhancers, especially among those used to improve memory, mood, and mental clarity.
How is Coluracetam different from other racetam nootropics? It has the ability to enhance high affinity choline uptake (HACU), which is a critical process in the synthesis of acetylcholine, a neurotransmitter essential for learning, memory, and neural communication. It involves the inhibition of ethylcholine aziridinium ion-induced hippocampal acetylcholine release in the hippocampus and septal cholinergic neurons, which supports better brain function and offers long-lasting cognitive improvement.
Coluracetam is a synthetic compound classified under the racetam family. The racetam family includes well-known names like Piracetam, Aniracetam, and the more advanced Coluracetam, also commonly abbreviated as MKC-231, which is known for boosting mood, motivation, and even enhancing vision.
How it Works: The Science Behind Coluracetam

Like most racetam, it also works by increasing levels of the neurotransmitter acetylcholine, which is associated with learning and memory. Coluracetam enhances the high affinity choline uptake (HACU), the rate-limiting step in the synthesis of acetylcholine, a key neurotransmitter involved in memory, learning, and cognition. This mechanism takes place in the hippocampus, where choline uptake is essential for maintaining neural transmission.
According to a study published in a Japanese journal, involving cultured cortical neurons and animal experiments, Coluracetam was shown to restore choline uptake even under conditions where it had been impaired by stress or exposure to neurotoxic substances like ethyl choline aziridinium ions.
Additionally, Coluracetam protects the neurons by reducing glutamate cytotoxicity, which can damage brain cells under chronic stress or injury. It is also known to ameliorate working memory deficits, enhance water maze learning in rats, and reverse phencyclidine-induced behavioral deficits.

Benefits of Coluracetam

Memory Enhancement
It is widely known to improve working memory deficits and promote water maze learning. It’s especially beneficial when hippocampal acetylcholine levels are decreased, due to subsequent exposure to toxins or stress. It improves memorization and recall abilities and increases learning speed and information retention.
Mood Improvement
Coluracetam may benefit those with major depressive disorder (MDD) and generalized anxiety disorder (GAD). It enhances acetylcholine synthesis, which is linked to a notable reduction in anxiety and stress levels, leading to better mood and mental function.
Neuroprotection
It may help protect the brain from glutamate cytotoxicity, a form of neural damage, which happens in chronic neurodegenerative conditions like Alzheimer’s disease.
Improved Vision
Coluracetam is also known to enhance color vision, shape recognition, and optical vividness. Some users who have used it describe the effect as “HD vision” while others say it makes lights brighter and intensifies contrast.
However, enhanced vision is one of the most commonly reported benefits, but there is no scientific evidence to explain or confirm this effect.
Recommended Dosage for Coluracetam
Coluracetam is sold for research use and is not yet approved as a dietary supplement in many countries. Typical dosage ranges from 3-35 mg per day, often divided into two or three doses. Coluracetam is usually prepared as a stock solution, and its molecular weight is used to calculate the appropriate dose.
Repeated administration of Coluracetam has protective effects on the brain and does not cause any significant tolerance. However, more scientific evidence is required to support the dosage range for Coluracetam.
Important Guidelines:
- Start with a low dose and gradually increase.
- Use with a choline precursor like Alpha-GPC or CDP-choline to prevent depletion.
- The powder form of Coluracetam can be mixed with water or any other solvent like juice, for optimal delivery.
- It is recommended to store Coluracetam in a cool and dry place to prevent degradation and avoid repeated freeze-thaw cycles.
- Always consult your healthcare provider before use for appropriate dosage.
Side Effects of Coluracetam

Coluracetam is generally considered safe and well-tolerated, but like any other medication, it also comes with some common side effects:
- Headaches: Headaches may be experienced because of depleted choline levels due to increased acetylcholine synthesis. This can usually be avoided by taking a choline precursor like Alpha-GPC or CDP-choline.
- Nausea or Vomiting: Gastrointestinal discomfort may occur in some users; common or normal in individuals who are new to nootropics or take higher doses.
- Fatigue or Lethargy: Some users may feel tired or mentally drained, especially without proper sleep, hydration, or nutrition.
- Irritability or Mood Changes: Changes in neurotransmitter levels may temporarily affect mood in some individuals.
- Brain Fog: Users may experience cognitive dullness, although rare, often due to poor choline support or overuse of the supplement without breaks.
Disclaimer: Side effects can vary from person to person, so it’s best to start with a low dose, monitor response carefully and always consult a healthcare provider before use especially if you have pre-existing health conditions or to avoid interactions with other substances, including stimulants and drugs, as it can increase the risk of adverse effects.
Who Should Consider Using Coluracetam?

- Students who are looking to enhance their memory and concentration.
- Professionals who deal with demanding day-to-day tasks and require a sharp and efficient mental function.
- Patients with depression or generalized anxiety disorder. Must be used under medical supervision.

Coluracetam vs. Piracetam
Coluracetam and Piracetam both belong to the racetam family, but they work quite differently. Coluracetam increases the high affinity choline uptake enhancer (HACU), which is the rate-limiting step in producing acetylcholine. On the other hand, Piracetam does not directly affect choline uptake but improves neuronal membrane fluidity, which promotes a smoother communication between brain cells.
Coluracetam is praised for its fast-acting and mood-lifting properties, with the potential to treat major depressive disorder and working memory deficits. Piracetam, on the other hand, is more subtle and gradual in effect, commonly used for age-related cognitive decline or Alzheimer’s disease.
Coluracetam vs. Aniracetam
Coluracetam and Aniracetam both are cognitive enhancers, but they target different brain systems. Coluracetam works by enhancing choline uptake, directly boosting acetylcholine synthesis. Aniracetam acts on AMPA receptors and modulates glutamate activity, giving it anti-anxiety and mood-enhancing effects along with cognitive benefits.
Aniracetam is more commonly used for creative thinking, emotional resilience, and social anxiety. If you’re looking to ameliorate working memory deficits and enhance neural transmission, Coluracetam is the go-to; if your focus is on mood, motivation, and verbal fluency, Aniracetam might be more effective in this scenario.
Legal Status of Coluracetam
The legality status of Coluracetam varies based on country or region. In the U.S., it’s sold as a research chemical and not regulated as a drug or supplement. If you are planning to purchase Coluractetam, make sure it’s from a reputable vendor that provides COAs (Certificates of Analysis) like Swiss Chems.
Coluracetam should be labeled properly with quantity, concentration, and storage conditions.
