Hi, Dr. Jeff! I just wanted to let you know about something I tried that helped me tremendously. I wrote you some time ago about serious memory problems resulting from a pretty severe bout of insomnia. Well I took a product containing L-Carnosine, Acetyl-L-Carnitine HCL, DMAE (and Ionic Trace Minerals). I took a large dose of it faithfully for 6 months. I'm happy to report that my memory problem has almost vanished! I had almost given up hope. However, the results were incredible and I'm so pleased. I realize that you strive for the best in the products you offer. Just thought you'd like feedback on a combination that was tried with excellent results!
