did some research on it, and I may consider this....
how long have you been taking this and how does it affect you?
I started taking it 30 years ago. I was 27 years old. The most notable affect was extreme memory improvement. I like telling jokes, but I had a problem remembering the punch lines. I started taking this supplement and about a week later I read a joke book. I was telling some of the jokes and I could remember the jokes and the punch lines. I am talking about 20 or so jokes in a row. This was an amazing improvement for me. When I use it I feel sharper.
