I thought I would try taking this product for mild attention issues and low mood. I took it for about a week and had a very bad headache and felt twinges of anxiety that I have not had in a long time. I dealt with these issues through the use of calming herbs like Passion Flower, Ashwahganda, and holy basil, ample amounts of magnesium ( both oral and transdermal daily) along with mind/ body work, all of which worked very well. After looking at the ingredients I believe that my bad reaction of severe head aches was from the Ginko Biloba. This was my reaction to Ginkgo Biloba in the past as well. It did have a mind clearing effect but I did not like they way I felt on this at all, I prefer my regular mind, :) The head aches went away after stopping the product, as did the twinges of anxiety. It is a individual response of mine as I see that most are having a positive response.
