Brand i trust

I have trusted the Qunol brand's other products and been pleased with the results. I expect this product to deliver its promises.

Qunol brain health

I don't know if I have a good opinion yet it doesn't seem to have changed anything too much? I maybe should give it a little longer. I just started getting into the bottle four or five days ago, so yeah it does not have no adverse side effects like Neuriva did cause it has mass caffeine in it..

Worth a shot

Don't really know if it is doing any good, but I still take it hoping.

Maybe too early to rate

Not really feeling the focus yet but do feel a little more mental energy, hopefully not just a placebo type effect. I will try and “remember” to update the review later.

Qunol Brain Health Product

Been taking the product for just over 2 weeks and at times I think it is helping and sometimes I don't. So will continue to use the product for a few months to see if I can tell a difference.

Hopeful

My Mom was itchy after taking this product. Not sure it was as helpful as we had hoped.

Large tablets, no improvement noted

Bought this for my spouse, he does not note any improvement. I do not see a change in him either. Maybe it just helps prevent further decline (have a star for this). Also the tablets are too large. He has a hard time swallowing them so he will either crush or chew them. They should be smaller, or a capsule.
