Below is the prices I have seen for 1 kilogram of bulk powders of each choline:
CDP Choline - over $ 500
Alpha GPC - over $400
Choline Bitartrate - $20
DMAE - $20
I have some CDP Choline that I haven't tried yet as I am currently trying out the Alpha GPC as it is supposed to be the most potent of all cholines. Not sure why CDP would cost more if it is not up to the level of Alpha GPC.
Choline Bitartrate is supposed to be a poor man's choline. LOL. I see this included in my multi-vitamin in low dose. The company just had to use the cheapest ingredient they could find.
I'm not too familiar with DMAE but I read it works more than just being a choline. It is supposed to be good for skin as it is also used as ingredient on skin care products. It's supposed to be great for mood, memory, lucid dreaming, etc. I can't wait to try this choline out!
