α-GPC / CDP-choline = nootropic for healthy adults
The evidence
Acute dose shows no robust cognitive benefit in healthy adults; long-term human data is thin.
The mechanism, in brief
α-GPC (alpha-glycerylphosphorylcholine) plus CDP-choline (citicoline, cytidine 5′-diphosphocholine) are two choline-derived nootropic supplements that complement the atlas choline story.
