I purchased these after reading they assist with mental focus and memory. I have become a victim of "pandemic" brain and needed a natural way to feel better. I don't know if it is all in my head but I can say while taking these my moods have improved, I have a bit more energy, and feel a bit happier. Give it a try, it can't be worse than the other things we put into our bodies. I would have given it five stars but as stated, I am not sure if it is all in my head.
