Doesn't work! Sorry!!

I do honestly think that the creators of this product are well intentioned. I am not sure if they de-amped the ingredients but 5 years ago when I tried it the results were palpable. I purchased this 5 days ago from Sprouts and I felt absolutely nothing. I understand if it takes 2 weeks to get the full effect, but honestly if I don't feel the effect right away, what is the point anyway? Best of wishes to those for whom it worked. But it didn't for me. I gave it away to my neighbor and he also felt nothing.

Thanks for sharing your experience! Sorry to hear you didn't enjoy the same you benefits you have in the past. Everyone can respond differently to a formula like this. Additionally, the needs and sensitivities of our bodies can also change over time, and it may just be that this product is no longer the best option for you like once was, but we appreciate you giving Alpha Brain another shot!

Good 👍

[This review was collected as part of a promotion.] The product has a sturdy and eye-catching design. The taste is easy to drink and doesn’t cause any discomfort when consumed. However, the price is relatively high compared to other brain supplements on the market. The product quality is quite good, showing noticeable effects after 1 to 2 weeks of use

Imported focus

[This review was collected as part of a promotion.] The supplement helped with better focus at work and since it is caffeine free it did not disrupt my sleep. It is packaged well in a dark bottle and has no taste. I received the product as part of influenster

Alpha Brain on an Artist Level

Being an artist that has to create sometimes multiple concepts on a daily basis it can get difficult to keep the creative juices flowing at times. I started trying Alpha Brain about a week ago, giving it some days off some days on to see the difference and I have to say so far I've actually noticed a huge difference in creativity on days I do take this supplement. I'm beyond amazed to find something like this that you can actually see the results immediately. It got to a point that I felt like I didn't want to put down a pen one day without picking up a brush and trying something else. Helped me focus more on detail and still have the creativeness to go deeper into my work. I'm hoping with more of this I can break the boundaries of my artistic abilities as I've been pushing to do for so long. This is an amazing product and will absolutely continue to share the experiences I have with everyone. A big thanks to a close friend that suggested I try this!!!

Alpha Brain boosts focus and clarity—clean, effect

[This review was collected as part of a promotion.] I’ve been using Onnit Alpha Brain for a little while now and I’m genuinely impressed with the results. It gives me a clean, focused mental boost without the jitters or crash you get from caffeine. I noticed improved concentration and mental clarity, especially during work or reading. The ingredient quality is top-notch—natural, well-researched, and caffeine-free, which I love. The capsules are easy to take, have no weird taste, and the packaging looks sleek and professional. While it’s a bit of an investment, the effectiveness makes it 100% worth it. If you’re looking for a reliable nootropic that actually works, Alpha Brain is a game changer!

Alpha Brain helps with focus, memory and reaction

[This review was collected as part of a promotion.] I received this complementary in exchange for my honest review. I love how ONNIT did it again with their amazing products. Alpha Brain is daily cognitive support which helped me stay focused on my tasks at hand. With continued use, this dietary supplement not only helps with focusing but also supporting memory and reaction time. I highly recommend this to anyone looking to get into the zone with this caffeine free blend of nutrients to help increase and improve cognitive functioning.

Just started taking them for the first time

[This review was collected as part of a promotion.] I received these pills, complementary from influencer from my honest opinion and I will have to say that I don’t really know how they’ve been effective just yet. I just started taking them and I just received them. The taste is not bad. The packaging is nice. The ingredients seems safe and clean and eco-friendly and I will highly recommend them.
