Coffee good but where's the energy??

I paid for a sample of 4 pods. Vita Cup advertises as coffee with vitamins for energy, increased brain function, etc. I didn't get any added energy nor did I feel that my mind was any clearer (Fibro fog is a real pain in the brain!) I used the 4 pods on consecutive days & didn't use my regular brand.

The coffee taste was good but I just don't feel I got any other benefits to warrant paying more.
