Good Results
I am not a doctor, but I can attest that Qunol Brain Health Focus Plus is working for me. I must confess that I am no spring chicken and was experiencing memory problems that go along with aging. Furthermore, my doctor has me wearing an oxygen tube, and I was worrying about what happens to my brain when something goes haywire in that department. I began to search for an OTC product that might help and noticed that the claims of one product widely advertised on TV were not supported by research while Qunol does have scientific support. I've used the product for several months now and have indeed noticed a decrease in my symptoms. I feel confident recommending the product to others in the same situation.

Useless
Of all the supplements I've tried, this was the biggest waste of money. I just finished the bottle and honestly can say I gave it a good shot, but really it is as useless for memory as a multivitamin would be. Furthermore so expensive and each dose is 2 hard white pills. I've been using brain supplements since college and literally this is useless.
