I've had reduced mental focus and depression for about 5 or 6 years, but recently it became intolerable. Tried several things to improve it with no success. Ordered some Lion's Mane, trying and hoping for relief. Within the first day there was a difference but by day three, the depression is gone, I can focus and accomplish thing I couldn't do for years. Soooo impressed, and ever so thankful. I could only hope it could work as well for others. A true game-changer!!
