GREAT product!! No complaints at all!
Size: 90 Count (Pack of 1)
So I got this product as an experiment. I don’t like taking prescriptions - but that is just me. I have the most boring job on the planet. And it’s all I can do to make it just through the morning without falling asleep. when I saw this product, I decided to give it a try. I am totally and completely shocked how well this works. It doesn’t make me jittery at all. It just makes me feel alive and alert and ready to roll. And I can focus on the monotonous tasks at my job. When I do take them, I have to take them in the morning. they do last all day - again - this is for me. but I found when I took them in the afternoon, I was still wide awake at 1:00am. Which put a damper on my trying to drag myself out of bed and to work at the most boring job ever.

good experience so far
Size: 60 Count (Pack of 1)
I’ve been taking Qunol Brain Health for a little while now, and overall I’ve had a good experience with it. What stood out to me first was that it didn’t upset my stomach, which I’ve run into with other supplements. I feel like I’ve noticed a difference in my ability to stay focused during the day, especially when I’m working on tasks that usually make my mind wander. My energy levels also feel a bit steadier, without that late afternoon mental fog.
The capsules are easy to swallow, and I like that it combines several ingredients aimed at supporting memory and concentration rather than having to take them separately. It’s obviously not an overnight miracle, but with consistent use I do feel sharper and more mentally “on.”
The only downside for me is the price—it’s a little higher than some other brain supplements I’ve tried. But considering the quality and how it makes me feel, I think it’s worth it.

Way too expensive

Great product, but Costco is more affordable even when not on sale.

Definitely worth it!!
Size: 60 Count (Pack of 1)
After completing one bottle, I have to say that I have noticed a difference in not just my short term memory, but overall, how I can focus throughout the day. I'm on my second bottle now.
