Great product for the money.

[This review was collected as part of a promotion.] Nice size capsules, doesn't smell or taste like anything, which makes it easy to take. Came in very secure packaging. Great value for the money. Nice ingredients list, no harsh chemicals. The effectiveness is great, have only been taking for a little over a week, and can already see some improvement in my focus and memory.

Too strong for me

[This review was collected as part of a promotion.] Unfortunately this product didn’t work out for me. I had panic attacks all day when using it and felt like I couldn’t concentrate. I even tried only take one pill. Overall I think it’s too strong for me and might be better for others whose bodies adapt better to 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.

Great Supplement!

[This review was collected as part of a promotion.] After trying these for two weeks, I definitely have a better perspective of this supplement! I have felt more focused and have had a much easier time remembering things like names of new people I meet, which usually is a bit tough for me. The bottle is just a standard pill bottle, but the label has all the instructions and information you need. Aside from working well, the pills also, don’t have a bad taste the way that many supplements do. If you’re looking for something that may help you with your memory and focus, I think this is great value for your money.

Great product.

I love alpha brain. I have used it for over a year and enjoy the way it helps me and i offer it to coworkers all the time. For some a huge difference and for most a little difference throughout tbe shift. Me and my friends at work like it alot. We work night shifts in health care.

Alpha Brain

[This review was collected as part of a promotion.] I wasnt able to actually notice the difference i took them for a couple of days and i kept getting an upset stomach. I stopped just to make sure it wasnt a virus but i tried a second week and still the same i guess my stomach was sensitive to a certain ingredient. But aside from that i didn't feel jitters or and mood changes.

worth it

[This review was collected as part of a promotion.] truly helps with cognitive function, especially when working on complex projects or multitasking . i’ve noticed an improvement in memory recall and mental sharpness throughout the day . ingredients: i appreciate that it contains natural nootropics like Bacopa Monnieri and Alpha-GPC, which are known to support brain function . there are no stimulants like caffeine, so there’s no jittery feeling or crash . value: while it’s a bit on the pricier side, worth it

Good for your brain

[This review was collected as part of a promotion.] I’ve had a noticeable improvement in overall how I think and feel, with these, I feel more focused, my mind feels more clear, and overall, I feel more sharp. The price is up there, but I think it’s worth it. It took a good few weeks for them to fully take effect, but they’re easy to take, and work well!

Clear focus and mental boost without caffeine!

[This review was collected as part of a promotion.] I’ve always been curious about trying nootropic supplements, and I’m really glad I gave Alpha BRAIN a shot. I’ve been using it for a short time and already feel a difference. I’ve noticed I’m more alert, focused, and mentally clear, especially during long work sessions. I also really appreciate that it’s caffeine-free, since I’m trying to cut back on stimulants. It fits perfectly into my routine with no jitters or crash. l just a clean sense of clarity and concentration. I’m excited to keep using it and see how the benefits build over time!

Efficient booster with clean ingredients

[This review was collected as part of a promotion.] I personally found this product to be especially helpful on my burnout days. Didn’t have an odd after taste which is a huge plus for me and capsule supplements! It is on the pricier side but the ingredient selection makes it comparable.
