Clean ingredients.

[This review was collected as part of a promotion.] I was very pleased with Alpha BRAIN. The packaging is practical and elegant, the ingredients are high quality, the taste is mild, the effectiveness is noticeable within the first few days, and the price matches the benefits it delivers. An excellent choice for those seeking more focus and mental clarity.

Pretty solid

[This review was collected as part of a promotion.] For me personally 1 a day has worked great! I have really been having power performances at work and studying. The pill is flavorless and goes down easy! The package is great full of the details. All the ingredients seem meaningful with minimum fillers

Mind Crisp

[This review was collected as part of a promotion.] Very easy to swallow, I have taken 2 capsules daily for a week and my mind feels a bit more crisp. I will say, at 45 years old I have no issues with memory loss, so this may be more effective for some that do. Worth a shot.

Great product, helps me stay focused

[This review was collected as part of a promotion.] Great product! I wish it came with more since you have to take 2 a day. I noticed a difference within a week of taking the meds. I felt like I was more focused and aware. I plan to continue taking these to see if I see a significant difference after a few months

Get it!

[This review was collected as part of a promotion.] Thank you influenster and Alpha BRAIN. My husband and myself have felt improvement in our daily routine. We’re more alert and focused. We’re a family of seven so we’re always on our toes with our children. I recommend having a decent meal with water before taking the vitamin. If you don’t, you may experience stomach aches. The colors on the bottle are eye catching. Some of the ingredients in this supplement are L-THEANINE, ALPHA GPC, HUPERZIA SERRATA EXTRACT, and VITAMIN B6. The supplement is also caffeine free and gluten free! I included a picture of the nutritional label for more additional information. There’s no bad taste to this vitamin. I recommend this supplement in your daily routine!

mixed results

[This review was collected as part of a promotion.] Tried this for a mental boost, but results were mixed. I noticed a slight improvement in focus, especially during long work sessions. No jitters or crash, which was a plus. But the effects weren’t as strong or consistent as I hoped. Might work better for some than others.

review

[This review was collected as part of a promotion.] My husband was excited to try these, while the capsule is quite big.. there is no taste. After almost two weeks he started to feel a slight difference and he will continue taking them to feel better.

Its a 50/50 guys

[This review was collected as part of a promotion.] I did not feel any difference tell you the truth. I gave 3 star because there is a chance that it works but I didn’t take it long enough. So I didnt want to give maybe a great product, not enough points

Try for yourself I’m not sure

[This review was collected as part of a promotion.] This could be user error but I didn’t really feel an effect for this product. I mean it felt like I was taking a vitamin but not sure how it really helped. Slept a little better through the night so maybe that was it. Packaging is great.

Doesn’t work

I’ve been taking alpha brain for almost a month now. Absolutely no noticeable differences in my cognitive function. I’m in sales and was hoping this would give me even more of an edge. A cup of coffee has more benefit than alpha brain does. Save your money.

reply from Customer Experience

Thanks for leaving us a review about your experience with Alpha Brain! We’re bummed to hear that you didn’t have the experience that you expected while taking this product. We all respond to supplements differently, not only in how they effect us but how quickly they effect us. We definitely recommend taking the product at the recommended dose for a solid two weeks before deciding whether or not it’s working for you. After that time, if you’re still not feeling it, please feel free to reach out to us directly for further assistance.
