Most citicoline vs alpha-GPC comparisons miss the point. These compounds work through fundamentally different pathways, serve different purposes, and come with a genuinely different safety profile. Here is what 18 years of research and personal testing actually tells you about choosing between them
Working memory is the cognitive function most directly responsible for how intelligent you seem — and how intelligent you feel. Understanding its biological capacity limit (4 ± 1 chunks), why the prefrontal cortex is uniquely vulnerable to stress and sleep deprivation, and the specific interventions with RCT evidence for improvement is the difference between vague advice and a precision protocol. This guide covers the neuroscience, the clinical evidence, and the four-layer optimisation protocol that Peter has refined across 40+ Creyos testing sessions.
Alpha-GPC is a pharmaceutical compound approved by prescription in Europe that most people treat like a casual supplement. After 18+ years of research and the 2,044-patient clinical trial that no other cholinergic supplement can match, this complete guide covers what Alpha-GPC actually does, what the evidence shows, the TMAO cardiovascular consideration every user needs to understand, the 50% vs 99% form stability distinction, and the Bacopa Monnieri pairing that makes it most powerful.
