Choline is a natural compound, you can get it by eating eggs. Most people take it as a supplement the same time
with piracetam, you can buy them combined as well. It's definitely discussed in research as well as forums:

"The results of these studies demonstrate that the effects of combining choline and piracetam are quite different than those obtained with either drug alone"
As far as choline goes, I eat an egg every day, and get my vitamins and minerals from fresh fruits, veggies and legumes. Just as you can obtain Vitamin-C or choline from a supplement, so too can you obtain them from natural sources. From what I understand of nutrition, the natural sources deliver the same nutrients in ways that our bodies can metabolize better.
I'm open to trying piracetam again, but it just doesn't seem all that significant to justify even the extra cost of buying it (and the supplements) and becoming dependent on it. If someone here actually does think it's worth it, I'd be very interested in hearing from you, provided you don't own a nootropics business.
One egg isn't going to do it. One egg gets you <200mg of choline, if I remember my research right, while you need more like >1000mg/1g to really see piracetam's effects. My DNB scores improved more with piracetam+choline than just piracetam: http://groups.google.com/group/brain-training/browse_thread/...
