I have been taking the Advanced Memory Formula daily for about a month now and have only noticed one positive result - somewhat greater alertness but zero memory benefit. I noticed that a component ingredient in Vinpocetine, which I've taken before and gotten the same result - so I think that may be the only active ingredient that's having a positive impact. I was impressed with the compelling online commercial, but so far the results have fallen far way short of the promise. I ordered a 90 day supply and will continue taking it for the duration, but if my first month is any indication, I won't be reordering.
