Yes, I can confirm I have been taking CDP choline for over 6 years, and I can also confirm that as Rick said, I am as handsome as ever,in fact, when I think about it, even more so....
But back to the topic, CDP choline is given to stroke sufferers, where it aids brain metabolism and recovery. I have been able to scale down to one 250 mg cap per day. I have taken it in combination with curcumin for about the same length of time. Olsen is also right, it also decreases BBB permeability. It is natural to the body, and seems very safe.
