Great to improve memory

[This review was collected as part of a promotion.] I received this free complimentary product from influencer I don’t have much problems with the memories, but it’s good to take them to prevent any potential loss of memories that comes with certain age. I start taking one by one and while I did not notice my major changes I felt more focused. My mind was sharper as well.

Nice formula

[This review was collected as part of a promotion.] Actives in formula seem to have a sinergetic effect, I do like the fact that is has L-Theanine which works great for me. Makes me feel calm and make it way easier to focus. Packaging looks sturdy and description of product is accurate.

Really works!

[This review was collected as part of a promotion.] Product ws great, helped me to focus better during the day. It did not leave a bad taste and I didn't have trouble swallowing the tablets. Overall it was a great product to try and I will be purchasing them in the future.

Great ingredients!

[This review was collected as part of a promotion.] I was so excited to try this because I have a hard time concentrating on tasks lately, so Im thrilled to see if this helps me. I like that it doesn’t have caffeine so I can still take it in the afternoon. I also enjoy that it doesn’t really have a taste and its easy to ingest. The only thing I noticed was that my stomach was a little bit upset after taking it the first time, but it didn’t really happen again.

No difference

I work 14hrs to 16+hrs a day for 14 days straight. I tried this for two months hoping it would help increase my focus during those long hours. I experienced no improvement during those couple months. I'mback to the reliable excessive amount of caffeine to keep me going.

Very effective

[This review was collected as part of a promotion.] I use this Alpha brain dietary supplements for about three weeks once a day and I already can see a difference! I’m more focused, concentrated during my study and working. Also this supplement helps support the memory. Good ingredients, easy to use and nice results!

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.

Great for dreaming!

It took a while, I'd say about 2 weeks to kick in. After the first 2 weeks (I take the recommended 2 capsules 5 days a week) I noticed I wasn't as "foggy". And I have to say, I dream EVERY single night now (used to be MAYBE once a week) and I can remember most of my dreams!! I can't say it's life changing, maybe I could dose up. But it's deffinatly doing something cognitively little by little. I'm going to try Black Label and I'll give my opinion on the difference!

No jitters, No crash

[This review was collected as part of a promotion.] Okay, so I’ve been trying out Onnit Alpha Brain for the past few weeks, and I have to say… I’m honestly impressed. 🤯✨ I was a little skeptical at first, but this stuff actually helps me stay locked in and focused — especially when I’ve got a million tabs open (literally and mentally 😅). No jitters, no crash, just clean mental energy and better clarity throughout the day. Whether I’m working, creating content, or just trying to stay on top of my game, Alpha Brain has become a go-to in my daily routine. If you’re looking for a little brain boost, this might be your new secret weapon. 🧠💥

Sometimes works

[This review was collected as part of a promotion.] I didn’t take it consistently — just on days when I knew I’d be mentally maxed out. Think: heavy workloads, creative projects, or when I had to pretend to be highly functional on little sleep. On those days, I sometimes felt more focused and clear-headed, but it wasn’t life-changing. I didn't have any noticeable side effects, but individual results can vary.
