This has been really helpful staying cognitively sharp all day long!
I wake up really early everyday and before I would hit my proverbial wall about 3:00 in the afternoon. I couldn't really handle making decisions on anything and my mental clarity was definitely on the decline. I have not had that problem since I started taking MasterBrain two months ago. Life changing! I can tell when I don't take it, I am not as sharp as I am during the week when I am taking it. Highly recommend it!
