To clear up some things regarding l vs dl choline bitartrate mentioned earlier:
The study that noted no benefits with 2-2.5g acute choline bitartrate didn’t specify, but they did say they got it from BulkPowders UK, so finding out what they use would clear that up.
Similarly, the study that found that choline from eggs had a ~4x higher choline response/AUC than an equal dose of choline (in mg) from choline bitartrate got if from BulkPowders Netherlands, so it seems like they both used BulkPowders choline bitartrate. Clearing up wthat BulkPowders uses would then help clarify this discussion a bit, perhaps, shed some light on it.
The study that did not acute improvements in visuomotor performance with 2g choline bitartrate also didn’t specify l or dl.
EDIT: I just checked on Amazon dot co dot uk, on Bulk Powders’ product page for their choline bitartrate, and in a question, they responded:
This product is DL Choline Bitartrate
So perhaps that explains why 2-2.5g didn’t note acute benefits with dl, when 2g with an unspecified form did? Perhaps, quickly assuming dl is only half l, that 2-2.5g would only be 1-1.25g, which is a fair bit less than the 2g that did note benefits. So maybe you do need 2g of the l, or more than 2-2.5g of dl if that is the case?
Guys, I’m genuinely just curious about choline and want to get as many views and opinions as possible, so I’d greatly appreciate Joey’s, and anyone else’s feedback on the matter, and not just to be called a “Goon” (regardless of if the connotation for that is positive, negative, or neutral). Check through my posts, and you’ll see I post a lot regarding nootropics/choline/studies/research, so would definitely like to have the most informed views/opinions/conclusions on the topic as possible, and also update my posts/topics with said information to help other people who may be curious as well.
