I have tried numerous supplements for memory loss...nothing seemed to work for me. At 66 years old, it was very frustrating, and expensive! However, within 2 weeks of starting Lion's Mane extract, my daughter asked what was different? I wasn't repeating the same stories and questions, also I wasn't mixing up names! I'm remembering people and their names from 20 and 30 years ago...incredible!! To anyone that's wondering, try it! It worked for me.
