Had some great focus days!

[This review was collected as part of a promotion.] I have really enjoyed trying my Alpha BRAIN supplements. The capsules are easy to swallow and they don’t upset my stomach at all. While it could be a coincidence, I’ve definitely noticed some very focused and productive days since I started taking them. I believe it would take consistent use over 4–6 weeks to really gauge any long-term improvements in brain or memory function, but so far, the experience has been a positive one. All in all, I think Alpha BRAIN is worth trying if you’re looking for a potential boost in focus and mental clarity.

Not a favorite

[This review was collected as part of a promotion.] I was skeptical to try this product at first because it was not FDA approved. When I first try it I didn’t see a difference. I do like that it doesn’t have caffeine but I would bragger take a natural supplement.

Works great! Go for it!

[This review was collected as part of a promotion.] I love the Alpha Brain Memory and Focus Support Dietary Supplement pills, as they work great and helps assist with mental focus and it’s one pill per day, so it’s worth it for helping your mental flow, so I highly recommend this to anyone who wants to try it! It worth the purchase as it’s not too expensive either!!

It works!

[This review was collected as part of a promotion.] I was not expecting much from this. After taking it every day for a few weeks now, I DO feel clearer and more focused. It used to take me a few hours to really hone in on a new project, but now I’m able to think about it and dive right in!

Would try again!

[This review was collected as part of a promotion.] I am one that does try to utilize supplements everyday - I have a regimen that covers most all items except for memory/cognition. After using this product for a couple of weeks I can say that I think in conjunction with my existing regimen my brain did feel a bit more focused . I did not notice an after taste and the only reason for 4 is that I prefer supplements that only require one tablet per day as I’m already taking 5 others daily, but this would be my only drawback.

Didn’t do much for me

[This review was collected as part of a promotion.] I did take these I didn’t notice much of a difference I did notice I spaced out a bit less but other than that didn’t do much overall for me. Personally I wouldn’t buy it again but they’re not bad it’s a medium sized pill so not hard to take. But just because they didn’t work for me doesn’t mean it won’t for you.

Easy to take

[This review was collected as part of a promotion.] While it’s difficult to generate a view of a supplement’s effectiveness in a short time, I am excited about this products claims! I can always use something to help with focus and memory. The pills are on the larger side but they don’t taste like anything and are easy to take. I’m excited to see the long term effects of these!

Sick for hours

My partner has taken this supplement without negative reactions; however, it is worth noting that I puked on myself and in my car after taking this supplement. I took as directed with a light meal and was sick for hours. It definitely isn't for everyone. I even gave it a second chance and had the same results.

Alpha Brain

[This review was collected as part of a promotion.] I’m well aware of this brand because of how popular it is. Simple, fool proof ingredients, affordable with a subscription and works well. You take 2 a day and get to your work! Packaged well and leaves you laser focused in getting your work done!
