I'm no biochemist, obviously.

I'm reading about people who, apparently, are taking their daily piracetam doses with choline. Does this mean that the piracetam is taken in conjunction with a choline supplement? If so, why?

Does choline facilitate the therapeutic effect of the piracetam? Or, does the choline perform some protective function, guarding the body against (presumably) a potential negative side effect of piracetam?

Possible headaches from large doses of piracetam may be alleviated by coadministration of an acetylcholine biosynthetic precursor, or a drug with cholinergic effects, such as choline bitartrate, choline citrate, choline alfoscerate, lecithin, cyprodenate or centrophenoxine.
