Annie M. reviewed Qualia Mind Caffeine Free
I took this 5 days on 2 days off (nonconsecutive), on an empty stomach as recommended, and did not notice a difference. I took them from 1/2/20 to 1/13/20.
Great formula
I would definitely use the product again and highly recommend it for focus and working long hours. The price point is a little heavy, but if you can budget it. Get it.
