Good product by Onnit! A must try!

[This review was collected as part of a promotion.] Onnit Alpha Brain definitely delivers a noticeable boost in focus and mental clarity. After a few days of use, I felt more dialed in during work and less prone to distractions. It didn’t feel like a jittery caffeine rush—just a smooth, natural sense of alertness. The ingredients are solid, and I appreciate that it’s stimulant-free. The only reason I’m giving it 4 stars instead of 5 is that the effects can be subtle, and results vary from day to day. Still, for anyone looking for a gentle cognitive edge without caffeine, it’s worth trying!

No Effect Not Worth it

I gave Alpha Brain a shot for 4 full months. Did not see any results whatsoever. Absolutely no change in focus or memory. Very disappointing as I was hopeful I would feel a difference even so much so I originally signed up for subscription. I have since cancelled and will not be reordering

Alpha Brain

[This review was collected as part of a promotion.] I have been taking these supplements so far, I like them. This is for cognitive function which I needed as I tend to not have focus on my tasks and I do tend to forget things easily, I feel like I have been having a sharper focus which is great for school days. The packaging is great and the value as well. It’s worth it.

Will purchase again

[This review was collected as part of a promotion.] Using it every day! Great product that’s helped me more so than any other supplement. Not like this one thing solves everything but it’s a good boost for mental focus and energy. Not a big after taste either.

Getting a new start

I purchased Alpha Brain 3 weeks ago for my less verbal Husban who is suffering from memory lost, I noticed this week he's beginning to recognize being home and names of the streets in our neighborhood. I CAN see more of an alertness just this fast.

Amazing Product!!

I’m so glad that I found this product! I work in a high pressure, fast paced work environment and Onnit Memory and Focus has been a tremendous help without the caffeine influence which helps since I’m caffeine intolerant. I especially noticed an improvement in my memory recall ability. Excellent product!! I highly recommend it.

Might work better for others, but it wasn’t a game

[This review was collected as part of a promotion.] Mixed results – not sure it’s worth the hype I tried Alpha BRAIN hoping for better focus and mental clarity. Some days I felt a slight improvement in alertness, but other times I didn’t notice much of a difference. It’s hard to tell if it was the supplement or just a placebo effect. I do like that it’s made with natural ingredients, but the price is pretty high for something with inconsistent results. Might work better for others, but it wasn’t a game-changer for me.

Just not sure....

[This review was collected as part of a promotion.] So I got these for free to try. I waited till I used the whole sample container to give my review since I don't feel like after 1 dose you can truly say yes or no. I'm just honestly not sure there was any improvement to my memory. That's just being honest.
