Karina D. reviewed Qualia Original Stack
Although I can really appreciate that the company is really trying to do something great here, what they are offering as far as formulation goes, it did not really fit my chemistry. I had this weird side effect to the second bottle pill, and headaches were constant even after change the dosage to 1:2 ratio. I would totally give it another try if they change the formulation, but for now I am gonna have to stop using it.
Good product, all around
I gave it 4 stars bc the initial start was a little unpleasant: headache, stomach discomfort. Then I realized I needed to drink more water AND more coffee! Mentally, it lifts the proverbial fog and keeps one on point with a veritable calm throughout the day.
