Choline Bitartrate for Poor Memory

How it was tested: 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.
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.
Dose: 2000–2500 mg
Tested as: single acute dose of 2.0-2.5 g choline bitartrate, memory tests given 60-120 minutes later, in healthy young university students
