After using Advanced Memory Formula for a few months, I have noticed improved alertness. I am 68 years old, and just completed my master's in Arts of Teaching. I began taking this supplement while still in my Student Teaching phase, and I noticed I was far more alert than the regular teacher of the class who is 20 years younger. Further, my memory was evidenced to be a big help to her. But, two years of hard hitting studies left me feeling exhausted, so I am quite happy to feel the confidence of having some extra positive support from this formula.
