Hello, my most recent concern is that I am so very tired, all of the time. I just purchased a vitamin called Healthy brain all day focus, because it has some of vitamin D some of B12 L-Theanine Ginkgo extract, Rhodiola extract DMAE and Huperzine-A. I found it in my local pharmacy, because I was looking for some type of vitamin to pick me up from constant feeling for sleep, even after a night of sleep. I know that I need professional advice on vitamins and the correct once. I am 62 year young.
