Appears good quality.

[This review was collected as part of a promotion.] Received Alpha Brain from Influenster for my honest opinion. The packaging is good and easy to access. The capsules are easy to swallow and don't have any bad smell or taste. They didn't cause me any negative side effects. I am not sure how to tell if they are effective. I think someone might need to take the supplement for longer. I would recommend giving it a try.

Onnit

[This review was collected as part of a promotion.] I love that it supports cognitive functions, including memory, mental speed, and focus. Which is super important. I would have to use longer to really see the results. But, so far it’s easy to swallow, and I’ve noticed I am more “in the zone” Will continue to take the rest of the bottle.

Seems to work well for me!

[This review was collected as part of a promotion.] So, what I like most is it does NOT seem to require taking it every day to see benefits. On a few days I woke up feeling less than well rested, I have taken it in the morning and felt more "on point" with clearer thinking about an hour after taking. No caffeine, so that's a plus!

Feel weird...

I haven't seen any other reviews about the pills making you feel weird. The 1st day I took 2 right after eating. A couple of hours later, I felt nauseous and light headed. It was so strange... I threw up a few times and that feeling was still in my gut. Didn't try again for a week. This morning I took 1 pill after a meal. I feel a little weird with an upset stomach. Nothing like the 1st time though. Thank goodness. Not sure if it's just my body rejecting these pills or what. I'm nervous to try another day. Maybe it'll get better? I can't handle it getting worse again. Anyone else feel this way?

Couldn't take

[This review was collected as part of a promotion.] I don't know what's in these that would cause a negative reaction but I could not take them. It took a few times to figure out that it was causing my skin to become all red and blotchy but when I stopped the blotchyness did too. I don't have any specific allergy that I know of related to its ingredients but it sure was something that caused it. So I can't provide any other details besides that.

Try it!

I can tell a big difference in my productivity after I take it in the morning. I can pivot from one thing to the other and keep going. I haven't really experienced that possibility in my daily life up till this point. Can't speak for everyone else, but it's definitely worth trying.

No bad taste at all

[This review was collected as part of a promotion.] Great packaging, it was completely sealed and a little difficult to open but that’s good. I didn’t feel any bad taste or bad after taste, just like a little herbal while you have it in your mouth. I do feel more focused.

Thank you

[This review was collected as part of a promotion.] Alpha Brain helped me feel a bit more focused and clear-headed, especially during busy days. I liked that it’s caffeine-free, so there were no jitters. However, the effects weren’t dramatic. Also, I wish the ingredient amounts were more transparent. Overall, worth trying if you're curious, but results may vary.

Effective!

[This review was collected as part of a promotion.] Great packaging detailing all the great benefits of the supplement, the capsules were easy to digest and had a neutral flavor. After being consistent with taking it per recommended dosis I did felt an increase in my productivity at work and remembering stuff I usually easily forget (like where I put my phone/keys/remote control)

ONNIT Alpha Brain – A Game-Changer for Focus and M

[This review was collected as part of a promotion.] I’ve been taking ONNIT Alpha Brain consistently and have noticed a real difference in my mental clarity and focus. It helps me stay sharp, especially when I’m juggling multiple tasks or absorbing a lot of information. I feel more alert and productive throughout the day—even during high-stress situations.
