Yes makes sense b5 is required for acetylcholine production “Pantothenic acid becomes coenzyme A, a cofactor necessary for acetylcholine production”b5 it was better, but from experience, taking only 50mg b5 3h before sleep is the fastest way to have a good night regardless of other factors.
I suspect people get enough dietary choline without supplements and that supplementing choline can be dangerous as it might cause elevated levels of acetylcholine. I do like to have a few eggs at night to improve my dreams
