I have been taking the Advanced Memory Formula for about 2 months now, but even after only 2 weeks, I found myself remembering things better. I've had a poor memory all of my life, but after age 65 or so it kept getting worse, and I became accustomed to it, After a couple of weeks of taking the Advanced Memory Formula, I happened remember that my hubby said he was out of coffee creamer when I was at the store and it was NOT on the list! I used to NEVER remember anything if it wasn't on the shopping list! Other little happy surprises are happening every day. My memory is still not perfect, but much improved. I'll take this stuff for life! I have had issues with Afib, so I dare not consume caffeine, so I was very happy to know that the whole coffee fruit extract in this formula is caffeine free otherwise I never would have tried it.
