Cognitive Support

[This review was collected as part of a promotion.] Just started taking it because I lost it, but looking forward to seeing how this works. The pills are not super huge and easy enough to swallow. We shall see.

Not good

[This review was collected as part of a promotion.] I didn’t see any changes or benefits from taking this. Maybe it needs more time for it to work but I wouldn’t recommend it. The capsule size is average.

We appreciate your feedback after trying our Alpha Brain, although so sorry it wasn't a great fit for you! Because everyone reacts differently to supplementation it's not uncommon to have different experiences. Please note that this supplement's main focus is to help support memory, focus, and processing speed - and sometimes it can take time to notice these effects. Regardless, glad you tried it out!

Really good for brain health

[This review was collected as part of a promotion.] This is really rude for your brain health.As the ingredients are really nice and it absorbs by your body.Really well. It does works the way it should, and it helps you focus.

Pretty helpful for focus

[This review was collected as part of a promotion.] Felt like I could focus better for the most part, noticed this within about a week of taking this. No negative reactions to the supplement, pretty happy with results this far

Sharp with quick recall.

After taking Alpha Brain, I felt sharper with better recall. I very satisfied and decided to take 1 capsule on the weekends so I don't have to start from zero every Monday. Unless there is a more economical way to remain sharp, please let me know but I will continue with what I've started until I hear otherwise. Thank you,

Caffeine free!!!

Best Product For Focus. I’ve used this product for physical fitness all the way to my ESports career and I gotta say it’s the greatest for people that either suffer from Caffeine intolerance or who want that extra boost while they chug down a can of your favorite sports drink, highly recommended!!!

No Noticeable Changes

I've been taking this product for just over two weeks now and besides a very slight energy increase, I've noticed nothing substantial. Sharpness and clarity have remained the same. I'm taking the recommended dosage of two caps per day, and feel that to take any more than that would be both unreasonable and costly.

I’ve had better nootropics

[This review was collected as part of a promotion.] I’ve had better memory & focus supplements so this one was just alright. I wouldn’t say it’s worth the price tag. It tastes like normal capsule supplements do, wasn’t delightful but wasn’t so bad I couldn’t stomach it. I don’t really like the design or packaging but it does seem this brand is more aimed towards men so maybe that is why? The good thing is that it does give you some brain energy but for me personally, it wasn’t anything like extraordinary. But everyone is different and I also do take other meds/supplements that it could’ve interfered with negatively.
