Choline-uptake research small molecule · Fact sheet
Coluracetam
Also known as MKC-231 · BCI-540
Coluracetam is a research racetam also known as MKC-231. Animal and cell findings on choline transport do not establish human memory, mood or sensory benefits.
What is Coluracetam?
The research focuses on high-affinity choline uptake and acetylcholine-related signaling.
A mechanistic effect on a transporter is different from showing that a person thinks or functions better.
Benefits & claims
Readers encounter Coluracetam in discussions of cognition, mood or mental fatigue. The relevant study population and outcome determine whether those claims are supported.
What the evidence supports
- Repeated MKC-231 treatment improved some rodent memory and acetylcholine measures in injury models.
- The mechanistic study linked effects to the availability of choline transporters at synaptic membranes.
- Neither result establishes human sensory enhancement, antidepressant efficacy or a dosing schedule.
Research areas
- Cognition and memory
- Neurologic or psychiatric research
Dosage & frequency
No established human regimenThe reviewed sources do not establish a human treatment amount or frequency for Coluracetam. Animal and laboratory exposures are not human regimens.
How to read these amounts
An approved regimen belongs to a specific product, indication, and population. A study regimen describes what researchers tested; it does not establish a prescription or a safe self-use protocol. Products, routes, and formulations are not interchangeable. A prescriber uses the full label and individual clinical circumstances.
Personal accounts may describe amounts, schedules and outcomes beyond clinical research. They do not establish a regimen. Read the reported experiences
Formulations, interactions & practical context
- Identity and pharmacology
- The research focuses on high-affinity choline uptake and acetylcholine-related signaling.
Formulation differences
- A mechanistic effect on a transporter is different from showing that a person thinks or functions better.
Interactions & precautions
- The reviewed sources do not establish a comprehensive human interaction profile for this exact substance or combination.
What is still unresolved
- Reproducible benefit on everyday function in the intended population
- Long-term safety and clinically important interactions
- Equivalence of nonstandard products to research formulations
Side effects & risks
- Human adverse-event rates, chronic exposure and interaction studies are insufficiently established.
- Improving a deficit induced by a laboratory toxin does not establish safety in an intact human brain.
This is a summary of the cited evidence, not a complete product label. A lack of human safety data does not establish safety.
Clinical research
Limited or unclear evidenceThe cited primary studies involve chemically induced deficits in rodents and laboratory transport measurements. They do not establish human clinical outcomes.
Studies
Mouse memory-deficit and hippocampal acetylcholine experiment.
Laboratory choline-transporter mechanism.
Repeated administration in a rat injury model.
Personal experiences
Reports describe what someone noticed. They cannot establish cause, typical results, or how often a side effect happens. Amounts and schedules describe the individual account, not an effective or safe dose. Product identity and strength may be unverified, and missing details are left explicit.
No attributable personal accounts were found in the sources reviewed.
Approval status
Coluracetam is not an FDA-approved treatment for the cognitive or mood uses discussed here. Regional use, historical trials and online availability are separate from U.S. drug approval.
No FDA-approved product for this entry
Approval covers the labeled product, use and population. A trial phase does not establish success; a stopped program is not ongoing research.

Open questions
- Reproducible benefit on everyday function in the intended population
