Two choline donors.

Both are choline donors that raise acetylcholine for focus and memory; citicoline also supplies uridine, while alpha-GPC delivers a higher percentage of choline by weight. Their core effect overlaps.

What to do

Pick one: citicoline for the added uridine and a smoother feel, alpha-GPC for a higher choline yield. Stacking both rarely adds noticeable benefit and mainly raises the cost and the chance of a headache, the usual sign you have pushed choline too high.
