Choline Bitartrate
Plain choline with no special route into the brain — the hope was that more in the blood would be enough.
Say that in clinical terms
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.
