It’s ok

[This review was collected as part of a promotion.] I’m a person that it’s always moving around and doing a lot of stuff at the same time but also tends to forget everything. I tried this to see how it works I did get more focus while taking them. Didn’t like the after taste but it’s ok because it’s natural.

Nice product

[This review was collected as part of a promotion.] I didn't notice a big difference after taking these. Maybe one month isn't long enough. The bottle was nice and easy to open. The capsules were an ok size and easy to swallow with no after taste. The ingredients send good and natural. I'm sure the cost is good as well.

Didn’t Notice a Difference

[This review was collected as part of a promotion.] I gave this supplement to my husband to try since he studies a lot and sometimes has a hard time focusing. He took it consistently as directed, but unfortunately, he didn’t feel any noticeable difference in focus, memory, or overall mental clarity. It might work better for others, but in his case, it didn’t seem to have any real effect. Still, we appreciated that the ingredients are natural and that it’s an easy supplement to take daily. The pills don’t have any flavor, which I think a pro, but for the price we expected to have better results.

We’re bummed to hear that you didn’t have the experience that you expected while taking Alpha Brain. Being that we all have different needs, it's expected that we all respond to supplements a bit differently. Thanks for leaving a review about your experience and giving it a shot regardless! -- Cailee B. ONNIT Customer Service Associate #getonnit

Great, relaxing vitamin focus

[This review was collected as part of a promotion.] These are the great vitamin because it really helped me to focus on my studying. Also, it comes you a lot. It doesn’t have a lot of on it. It’s great vitamin also the price well it’s kind of expensive but it’s a great vitamin to use.

Subtle changes with great potential

[This review was collected as part of a promotion.] I tried Onnit Alpha Brain Daily Cognitive Support for a month, starting with a half dose before moving to a full dose. While I can't confirm any major changes in my focus due to a busy workload, I did notice a subtle increase in my energy levels. The capsules were easy to swallow with no bad taste. It's a decent supplement that gave me a mild energy boost, but the effects on focus were hard to measure.

Extra brain power

[This review was collected as part of a promotion.] I received a complimentary Alpha BRAIN by Onnit in exchange for my honest opinion. I tried so many vitamins and such to try to help energy levels and focus especially when trying to be productive at work, at home, and in fitness plans! This stuff is great. I took it with a quick breakfast and had no issues with my stomach feeling bad like other vitamins I’ve had before. There was a very subtle difference the first day I took it where I noticed the difference when it kind of “kicked in” but the other days it’s just been so steady overall improving my focus. My energy levels are better and it’s helping me to get to sleep quicker at night. Truly impressed with this stuff so far. The package is a nice design, simple but I do like the dark bottle. It looks so sleek and easy to identify. Really good stuff so far after using it for a couple of weeks! Capsules are on the slightly larger side but I didn’t even notice. Had no issues taking them at all. No aftertaste, no Weird feelings. Overall, the product seems to work so far as intended.

Try!

[This review was collected as part of a promotion.] I have been taking this for a few days now and can tell a small difference. The packaging is easy to open and the ingredients look to be very minimal. The taste is not that great if you do not swallow it quickly.

Causes Nausea

[This review was collected as part of a promotion.] The promise of improved focus and memory from Alpha Brain was intriguing since I could definitely use both. However, the formula gave me nausea, even though I took them with food and then adjusted the dosage the 2nd day to only one capsule. Hopefully, it works for others, but I couldn't 'stomach' them

After two weeks,its giving *nothing*

[This review was collected as part of a promotion.] I’ve been taking this for a few weeks now and haven’t felt much of a difference in my mental performance. The taste isn’t horrible though and the smell isn’t too strong. I’ll probably finish the bottle and see if there is any compounds effects for using this product.
