Alpha-GPC

nootropics

Alpha-GPC (L-Alpha glycerylphosphorylcholine) is a naturally occurring choline compound that crosses the blood-brain barrier to support acetylcholine production and cognitive function. It is commonly used to enhance memory, focus, and mental clarity whilst supporting brain health and neuroplasticity.

Benefits

Enhanced memory and recall
Improved focus and concentration
Increased mental clarity
Supports acetylcholine production
Promotes neuroplasticity and brain health
May improve athletic performance and muscle function

Dosage

300–600 mg per day

Upper Limit

1200 mg per day

Timing

Split into 2–3 doses with meals; morning and afternoon optimal for cognitive benefits

Forms & Bioavailability

Avoid concurrent use with scopolamine or similar agents

Research Summary

Alpha-GPC has demonstrated efficacy in supporting cognitive function, particularly in memory and attention tasks, with studies showing improvements in healthy individuals and those with age-related cognitive decline. Research supports its role in acetylcholine synthesis and potential neuroprotective effects through phosphatidylcholine production. Clinical evidence remains moderate, with most robust data in populations with existing cognitive impairment, whilst effects in healthy populations are more variable.
