Bests & Worsts Reviews from Amazon

I am 72 years old. I am a retired Ch.E from Purdue and have worked for over 40+ years in a laboratory/technical production, data gathering, statistical evaluation environment. I am saying I don’t approve or give approval of products randomly. I must say after using this product daily for over 120 consecutive days, that I have experienced a profound improvement in cognitive reasoning and memory recall. I frequently have actual recalls of classroom discussions of scientific applications from the 60’s. All I can say is that from personal results, this is a PHENOMENAL product.
