May hit each person differently.

[This review was collected as part of a promotion.] The package was eye catching. They didn't have a taste. The ingredients were a natural source. For value, I can't agree or disagree. I didn't notice a difference in memory or focus, but reaction time was on point. I'd be willing to try again for a longer period of time to see if there's any changes .

Great for clearing your mind

[This review was collected as part of a promotion.] I’ve been really liking this supplement. As someone who works from home a lot and has a job that requires a lot of mental capacity, this product has been life changing. It definitely has made me think clearly, even when I’m overwhelmed or if I’m having a long day. I have to say make sure you accompany this with a healthy meal. I did take this after having fast food and it did upset my stomach a bit. It’s a simple capsule so this product doesn’t really taste like anything and it’s easy to digest.

Waiting for results

[This review was collected as part of a promotion.] I haven’t really seen any changes yet, so this is why I reviewed this way. I do like that you get a lot in the bottle, and that it’s made with trustworthy ingredients! I just didn’t see a change for myself. I am continuing with them to see if anything happens. I do think the packaging is nice, and the taste is not bad

Thanks for reaching out and leaving a review! So sorry to hear that Alpha Brain did not work for you. Because everyone reacts differently to supplementation it's not uncommon to have different experiences. Please note that this supplement's main focus is to help support memory, focus, and processing speed - sometimes it can take time to notice these effects. That being said, if you are ever dissatisfied with your order, you can always contact our Customer Service team for further assistance!

Game changing product!

[This review was collected as part of a promotion.] I have been wanting to take Alpha Brain for a long time, thanks to the trials. I started taking the product and have been a loyal fan since then. I have had numerous traumatic brain injuries from martial arts, and college football, and the clarity that I get from the product is impressive. I like the product so much that I began taking Total Human because I feel like OnIt is very much on to something.

Great thing for busy days.

[This review was collected as part of a promotion.] I’ve been trying it for a few days. It works. I get better focus and energy. Perfect for busy days when you have a lot of things to focus. The label said it natural ingredients and no jitters like other supplements. Don’t use it too much or you can get a headache.

Alpha brain vitamin support

[This review was collected as part of a promotion.] These brain vitamins I call them work. they help you focus, they give you entry throughout the day. I feel better taking these than drinking a redbull through the day. They also help you think clear with memory focus. these vitamins actually do the trick. I recommend trying these to enhance your memory and gain focus.

Sharp Focus Without the Jitters!

[This review was collected as part of a promotion.] I’ve been using Alpha Brain for a few weeks now and have noticed a real improvement in my ability to focus, especially during long work sessions or when I need to stay mentally sharp. What I love most is that it doesn’t give me the jittery feeling that other nootropics or caffeinated products can cause. It feels more like a smooth, natural boost. I’ve also noticed a slight improvement in memory and reaction time, particularly when multitasking. The fact that it’s stimulant-free is a big plus for me. I take it in the morning with breakfast, and it kicks in gently within an hour. My only reason for giving 4 instead of 5 stars is the price—it’s a bit on the higher end for just 30 capsules, and I wish it came with a larger quantity for better value. Still, it’s a solid supplement if you’re looking for daily cognitive support!
