I've been taking Advanced Memory Formula for about a year now, and I have noticed a great increase in my ability to recall facts, names, details, etc. But about two months ago, I ran out of Advanced Memory Formula and was not able to reorder at that time. I really noticed a decline in memory and recall. I received my order last week and resumed taking it. I cannot tell you how much this formula has helped me in my thought processes and recall. It's not perfect, but it is a great improvement. I will try to never be without it again.
