Maybe worked?

[This review was collected as part of a promotion.] Honestly didn’t notice much difference using this product, even using the full container. The smell isn’t awful but not super pleasant when taking.

We appreciate your feedback after trying our Alpha Brain, although so sorry it wasn't a great fit for you! Because everyone reacts differently to supplementation it's not uncommon to have different experiences. Please note that this supplement's main focus is to help support memory, focus, and processing speed - and sometimes it can take time to notice these effects. Regardless, glad you tried it out!

Maybe?

[This review was collected as part of a promotion.] I did not find these entirely helpful. It was only a 30 day supply, so I never really felt any change. Maybe if you tried them for 6 weeks, you would begin to see results.

Thanks for taking the time to share your experience! We're sorry to hear that Alpha Brain wasn't the right fit for you. It's expected that we have a range of responses since supplementation is not one size fits all. Sometimes it can take a few tries to notice these effects. Experimentation is key! That being said, if you need further assistance you can always reach out to our Customer Service team at help@onnit.com, they'd be happy to help further!

Typical supplements

[This review was collected as part of a promotion.] Packaging was was expected for the product. I don’t think I noticed much of a difference in the duration that it was take . This is something you would need to maintain consistency with.

Focused

[This review was collected as part of a promotion.] I would use again, I felt like I noticed a difference a couple of days in. I felt like it helped me focus more. The capsule was on the larger side so that is the only negative.

Hi there, Thanks so much for giving Alpha BRAIN a try! If the capsule size is a bit tough to manage, one option is to carefully open the capsule and mix the contents into a small amount of water or a smoothie. Some people find that works a lot better for them. You might also want to check out Alpha BRAIN Instant, which is a powder you mix with water, same great formula, just in a drinkable format. Appreciate you sharing your experience!

Good supplement for light and progressive focussin

[This review was collected as part of a promotion.] I tried Alpha BRAIN and noticed a slight improvement in focus and mental clarity. It’s easy to take, but the results are mild and not immediate..

Didn’t work for me

[This review was collected as part of a promotion.] I didn’t see a difference when taking these. I was really hoping to see a difference but unfortunately I didn’t. Now that’s not saying it won’t work for someone else.

Thanks for leaving a review about your experience with Alpha Brain! We’re bummed to hear that you didn’t have the experience that you were hoping for. While we typically suggest trying out for 2 weeks to feel effects, being that we all have different needs, it's expected that we all respond to supplements a bit differently, and we're glad you gave it a shot. -- Cailee B.

Not a fan

[This review was collected as part of a promotion.] I tried the Onnit Alpha BRAIN supplement for several days, but didn’t feel much more focused than usual. It made me feel somewhat jittery and not quite like myself. Would not recommend.
