Nice

[This review was collected as part of a promotion.] Husband was a big fan. He said it was exactly what he has been hoping to find to help memory and acuity. Packaging is effective and I can't say taste was good or bad. We liked it and would buy again.

Eh

[This review was collected as part of a promotion.] I honestly don't feel any different. It's a bit of a bigger pill, which could be a problem for some people. It doesn't smell good, that's for sure. I don't know how I'm supposed to feel but I'm not noticing a difference unfortunately.

It seems like it is working

[This review was collected as part of a promotion.] Alright, so I've been taking this Alpha Brain for a bit and it is like hard to say if it's actually doing anything. I mean, I feel like my brain might be a little sharper, but it's tough to tell if it's just placebo or not. I've heard good things, so I'm sticking with it for now. So far no negative side effects.

Locked in

[This review was collected as part of a promotion.] There is a noticeable improvement in my focus when I take Alpha Brain. I am able to better concentrate on one project at a time. I am not distracted by things around me. Alpha Brain has been exceedingly beneficial in helping me get many of my deadline-oriented work done on time. I'd recommend it for anyone looking to lock their focus in.

Works but is too pricey

[This review was collected as part of a promotion.] So this is a pretty good supplement. I have felt a little more focused but I'm not sure if it's one I will continue to use. For the price I don't feel like you get enough of the product. I have found something similar that I will most likely start using.

Worth the try!

[This review was collected as part of a promotion.] ingredients and quality are great, I do think I would need to take it longer term to truly see if the effects are long lasting and if it is really effective. Has no taste and the capsule is easy to swallow. Pricing is on the higher end but reasonable.

Ok

[This review was collected as part of a promotion.] Hmmm…. I did not finish the bottle. I could not tell a difference. I’m not sure if you’re supposed to use it for so many weeks in order to see noticeable change. It’s a little expensive if you’re not noticing or seeing any benefits.

Pretty good

[This review was collected as part of a promotion.] The ingredients are good overall but I didn’t notice a huge difference after taking the supplements. I think as time goes on and with consistency, there would be more of a noticeable change as far as alertness, mental sharpness, etc. goes.

Easy to focus

[This review was collected as part of a promotion.] If anything, I wish it was at least a 30-day supply bottle. It's a 15-day supply if you have the recommended dosage. Very easy addition to your daily vitamin intake and no bizarre after taste. The pills are standard gel caps, but if you have issues with that, just split your dosage. Overall, it did help with my clarity and focus.

Thanks for taking the time to share your experience! We're sorry to hear that Alpha Brain wasn't the right fit for you.
