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.

Noticeable improvement in focus and memory 👍

[This review was collected as part of a promotion.] After taking Alpha Brain for about two weeks, I feel more focused and mentally sharp throughout the day. It helps me stay productive without any jitters or crashes. The capsules are easy to take and gentle on the stomach. Definitely a great supplement if you need extra support for concentration and memory.

Grandma recommended

[This review was collected as part of a promotion.] I received this as a gift from Influenster, I personally did not use it, I gave it to my grand mother, she’s older, she says it works well, helps her to stay more focused. The taste isn’t bad at all, the packaging is secure so the pills inside can stay good for a long time, ingredients are super gentle, definitely a value for the money!

Mental Clarity

[This review was collected as part of a promotion.] By the first two weeks of using this, I could tell my focus and memory had improved. I was doing the same thing as far as work and reading, but it was noticeable how much more I was retaining. This is my first order and will continue to use this product.

No change for me while taking.

[This review was collected as part of a promotion.] I didn’t see any changes since taking this daily for the full 15 days. I was hoping to see some improvement in alertness but I regret to say I did not. I’m grateful the brand and Influenster allowed me to try out this product for free in exchange for my honest opinion. I did take these at night on one occasion and I couldn’t sleep that night, but I don’t know for sure if this product caused that or not. One positive about this item was that I didn’t see any ill effects from taking it, so I call that a win.

Focused

[This review was collected as part of a promotion.] I have been using this for a week now and I definitely can feel a difference. I feel a lot more focused. It’s easy to take and I feel he could value for the money at cost. The ingredient quality makes me feel like it’s safe to take as well .

Ok

[This review was collected as part of a promotion.] This is my first time trying this brain supplement. The taste isn’t really worth mentioning; it’s quite easy to take. I’ve taken it twice so far and feel normal. Maybe I’ll need to finish the whole box before I notice any effects. I’ll share more feedback once I’ve finished it.

Great product

[This review was collected as part of a promotion.] These supplements have been a game changer for me while studying and working because it has made it easier for me to focus. I tend to struggle focusing but after taking these supplements I don’t have that issue. Also I love how easy they are to take does not leave weird after taste.

Nausea and Dizziness

According to the reviews, there seems to be a certain subset of people who react badly to this product, and unfortunately I was one of them. I took two pills with a light meal around noon (as directed), and a few hours later I felt intense nausea, dizziness, light sensitivity, weakness, and general motion sickness whenever I looked at a screen. Napping and eating didn't help it very much. The symptoms finally went away around 1 in the morning when I was able to fall asleep. I don't know what neurons this supplement fired up in my brain, but they weren't the helpful ones lol. Completely ruined my day and I certainly won't risk taking it again.

No

[This review was collected as part of a promotion.] It works but it also makes you sick. I was really excited about this product because I wanted to boost my memory. It was fine going down but I felt nauseated most of the day after taken it. It doesn’t taste bad but I kept thinking I was going to vomit. I don’t recommend
