Bests & Worsts Reviews from Amazon

I have been taking this product for about 6 months.It has been helping with my energy levels and my total feeling of well being. I take it every morning (2) with my other supplements after breakfast (5am).This combination is very effective on keeping me on track. I am 68 yrs old and drive 80 miles a day (to/from) to work and have for the last 15 years. I find that my attention and clarity of mind diminishes as I age and since I cannot retire yet, I need all the help I can get. I try not to take more than two a day, but sometimes I need a little extra help by noon; I never feel jittery or hyper, just able to continue my daily tasks. Thank you for formulating a product that produces such great results.
