My wife and and I, both 81-years old, have been on the Advanced Memory Formula for about two weeks and not noticed any significant changes that we can claim. My wife's memory is the primary target for using this product; mine is not so bad. We are testing the product by testing our cognition before and after a period of time, using the MOCA and CNS Vital Signs tests.
I have given the product a 3-star rating because at this time, I cannot say whether it is helping or not. if given the opportunity, will update rating on down the line.
