Get ready for a focus day

[This review was collected as part of a promotion.] It’s here!!! That good vitamin that will give you a boost to your day. There’s absolutely no taste. You will need to take a lot of water with it and after taking it for about 5 days you will have a better feeling and sense of what you are doing on your daily tasks. I certainly recommend, the bottle is small and can carry it with you any where you go.

Focus

[This review was collected as part of a promotion.] This is a pretty decent supplement! I noticed that I could focus more on stuff I was doing rather than getting side tracked while taking this. I was a little nervous because of the ingredients but I didn’t have any bad side effects. Didn’t taste bad and was able to take it without any issues! Great value and packaging for the price! I probably wouldn’t buy it again though.

Sharp

[This review was collected as part of a promotion.] This supplement has been around for a while so I was excited to get to try it. It’s definitely effective, as I felt very focused while using it. The down side is I got a headache which may have resulted from dehydration, so make sure you drink lots of water! It’s a bit pricey as the serving size is only 15 per bottle. The capsules have no taste, and the container is definitely packaged nicely!

Focused

[This review was collected as part of a promotion.] Definitely worth the money spent. I however was able to test and review this amazing supplement for free thanks to Influencter and Onnit! Definitely recommend for persons of the neurodivergent type. So you know it works wonders for me! Stay focused and remember to keep your mind prepared.

Very excited to try these

[This review was collected as part of a promotion.] I have been using these supplements for just over a week now. I didn't notice anything out of the ordinary the first few days as expected, but have seen some slight improvements now that they have been in my system for awhile. Overall, I feel like I am more alert throughout the day. I am more focused with the task at hand. Now, I can't say for sure that it is directly related to these supplements or the fact I made changes in my personal life. I am not a scientist and not 100% sure exactly what is in this product, but I do love the fact that there is no caffeine in the ingredients. I will continue to use as I still have about half of the bottle left and who knows, maybe I will see more of certain increase when it comes to my memory and focus.

Lots of vitamins in this supplement that support brain health

[This review was collected as part of a promotion.] I have been taking this for about a week. I have not really noticed a difference other than gives me a little energy. They have no taste and contain several vitamins. If nothing else they seem to be a healthy supplement!

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, we would never want you to feel stuck with a product that didn't meet your expectations, and if you reach out to our Customer Service team, they'd be happy to help further!

Alpha brain vitamins

[This review was collected as part of a promotion.] To be honest I have noticed a difference yet in taking these But I have not always remembered to be consistent and I don't know if it's supposed to cause instant results or over time. I did see some people reported getting upset stomach or other symptoms and it didn't affect me negatively in any way. There was no aftertaste or anything like that. I will probably keep taking them until I finish the bottle to see if I notice any additional change but so far I probably wouldn't buy them again

Thanks for sharing your experience after trying Alpha Brain! Everyone's experience can be a bit different with a formula like this. It's formulated to help support memory, focus, and processing speed, and it can take some regular use to really feel these changes. We suggest trying it for at least two weeks to give it a fair shot!

Amazing focus

[This review was collected as part of a promotion.] Clearer Focus Without the Jitters I’ve been using Alpha Brain for a few weeks, and I’ve noticed a real improvement in my focus and mental clarity. It doesn’t give a caffeine-like buzz, but I feel more alert and organized—especially during work or mentally demanding tasks. What I like: No crash or jitters Subtle but noticeable improvement in memory recall. Helps me stay sharp during long days. Some value for money, great packaging

Memory Aid After Breastfeeding: A Work in Progress

[This review was collected as part of a promotion.] I started taking these supplements to support my memory and focus after breastfeeding my baby. For those who don’t know, this period can be extremely depleting for nursing mothers, often leading to memory issues. I’ve been taking them for a week now, and to be honest, I haven’t noticed a big difference yet—maybe a slight improvement in focus. But memory problems still persist. I’ll continue taking them and hope for better results. The bottle is convenient, the tablets are easy to swallow, and they don’t have a strong smell, which I really appreciate
