Interested to try long term

[This review was collected as part of a promotion.] Packing was eye catching, and the ingredients seemed ok for consumption. The effectiveness seems to be expected, but I am sure results would be seen even more once taken consecutively for a longer period of time. No awful taste either!

Improved Focus & Memory

[This review was collected as part of a promotion.] So while I’ve only been taking these Alpha BRAIN supplements for about a week, I do feel more focused and more able to stick with one task as of late. I do feel a significant difference in terms of flow state and I have been struggling to remember things less than I had previously. I’m not sure how effective this will be in the long run, but as of now I’m content with them. A plus is also that while big, the capsule size is not huge and there is no bad smell to them.

Make sure to take with meal

[This review was collected as part of a promotion.] I love how it gives me energy without the rush from caffeine. Easy to swallow, great morning supplement. Do make sure you take it with meal, or at least some food, it does cause a little irritation if taken with empty stomach.

Great supplement

[This review was collected as part of a promotion.] It’s a caffeine-free supplement with ingredients like L-theanine, L-tyrosine, and vitamin B6, designed to support focus, memory, and reaction time. I appreciate the stimulant-free formula, but the pills are quite large and you have to take two daily. It’s also worth noting the claims haven’t been evaluated by the FDA. Overall, it seems like a well-formulated option if you’re exploring cognitive support. The price is a little bit high but you get 90 pillls. They do not have a taste.

Works great!

[This review was collected as part of a promotion.] These are effective for memory & focus support, which is really nice. They are affordable and obtainable. They come in a little resealable bottle. They don't have any particular taste, not a bad taste.

Looking forward to seeing some positive effects

[This review was collected as part of a promotion.] I've been taking this for about 3 weeks now, and so far, so good. I've not had any negative side effects so far. I am not experiencing any clarity and thought or anything else that's labeled on the package, but again it's only been 3 weeks, so I'm going to give it more time. I do like the packaging and the quality of the ingredients.

What I love the most: ✔ Noticeable boost in focus

[This review was collected as part of a promotion.] I’ve been using Alpha Brain by Onnit for a while now, and I can confidently say it’s a game-changer! As someone who needs to stay sharp and focused throughout the day, this supplement has truly helped me improve my memory and concentration. I feel more mentally clear and productive, especially during busy workdays.

Had a terrible reaction!

Took this product and a couple hours later I was so sick. Nausea, vomiting, diarrhea, dizzy, increased heart rate, the list goes on. I looked online to see if anyone had a similar reaction and negative side affects seem to be quite common with Alpha Brain. I will never take this supplement again.
