I have tried several products claiming to help with memory. 1 month on each of them left me with no noticeable improvement. However with this product, as I am nearing the end of the month, I was disappointed until 2 days ago, when I happened to be thinking about the job I held when I was first married (in 1961). Nothing unusual about that, but I realized that I remembered the names of the people I worked with from 60 years ago. That was amazing! So far... I'm very impressed.
