Choline Bitartrate for Poor Memory
Choline bitartrate is plain choline salt with no special brain-delivery advantage; the hypothesis was that raising blood choline would still boost acetylcholine-dependent memory acutely.
How strong is the research?
No Benefit evidence
Across three double-blind, placebo-controlled crossover experiments (n=28, 26, 40), a single 2-2.5 g dose of choline bitartrate produced no significant improvement on visuospatial working memory, declarative picture memory, or verbal working memory tasks. Bayesian analysis favored the null hypothesis of no effect.
