Great quality. I like that is low in mg. 350 is a little too much for me but it does help me focus and clears my mind. It does not help memory recall, it just brings clarity. lifts brain fog. I'm sensitive to the cholines but this one is effective when I want to come across clearly. Great quality feel to stay focused when doing an activity being work or being active. and then do another pill after after a few hours to stay on task while doing activity (not so great for memorizing for me at all as I tend to read a lot and this does not help to see what I just read).I tried some other brand at 650 mg and it was not even half the potency of this one, and my brain got tangled up because of those companies' low quality. I'll stick with this one when I need mind clarity.
