Great for brain power

[This review was collected as part of a promotion.] These Alpha Brain pills really work for mental acuteness and clarity! I have been taking before work and there’s no bad aftertaste, and it does make a difference in my focus. I would recommend, and they’re good value for money.

Worth a try!

[This review was collected as part of a promotion.] This was packaged very well. I actually had a hard time opening it because it was sealed very well. It did not help my memory as much as I was hoping, but I did notice a little difference with my focus. It is a bit large but I was able to swallow it after a few tries. Hoping others will have more success with it!

No effect at all!

I heard about this product from Joe Rogan. I bought two bottles of this stuff. After going through them, I can say there was no change in memory or focus. This is nothing more than placebo pills. I'm embarrassed to have wasted so much money for nothing.

Didn’t Notice a Difference

[This review was collected as part of a promotion.] I gave this supplement to my husband to try since he studies a lot and sometimes has a hard time focusing. He took it consistently as directed, but unfortunately, he didn’t feel any noticeable difference in focus, memory, or overall mental clarity. It might work better for others, but in his case, it didn’t seem to have any real effect. Still, we appreciated that the ingredients are natural and that it’s an easy supplement to take daily. The pills don’t have any flavor, which I think a pro, but for the price we expected to have better results.

Decent product

[This review was collected as part of a promotion.] Great packaging, there is no burp back taste wise. They don't really taste like anything. Clear easy to swallow capsules. I have noticed a little bit of a difference during the work week. More focus and more alert. I would recommend trying. But don't think I would continue taking these.

Not enough time to know for myself

[This review was collected as part of a promotion.] This is a Joe Rogan product, with a huge marketing push associated with his podcast. I tried my best to evaluate and try this supplement without considering the background and ownership. I received a 30 day supply and have completed my month of 'testing.' Before and during this trial I read about the experiences of others. There are two reasons for my 3/5 stars. First, I didn't see much of a result, of any. To be fair, I don't think 30 days is long enough to evaluate. The other reason for my rating is because of the high number of users who reported negative side effects. Supplements like this are not evaluated by the FDA, so of course we take reviews with a grain of salt. Salt. Just because someone got a headache doesn't mean it was because of this, etc. I will also disclose that I'm not a huge fan of supplements and prefer to do things like get sleep, stay hydrated, eat well, and be mindful. I think those things can affect us the most. However, if you find yourself in need of focus, it may be worth trying these out. They are more expensive than some others on the market, and you're paying for the name behind it.

NON EFFECTIVE

I purchased a 30 count bottle of Alpha Brain hoping from the great reviews that I would feel more alert and ready to go. After the 2 weeks were up, I felt literally nothing different. I was hoping to take these and like the reviews say, be focused and alert more than usual, but they had no effect.

Thanks for reaching out and leaving a review! Apologies that Alpha Brain did not work for you. Everyone reacts differently to supplementation, and 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 a few tries to notice these effects. That being said, if you are ever dissatisfied with your order, you can always contact our customer experience team for further assistance!

Whether I’m trying to stay productive, remember ta

[This review was collected as part of a promotion.] I’ve been taking Onnit Alpha BRAIN for a little while now, and it’s made a noticeable difference in my focus and mental clarity. What I love is that it’s caffeine-free, so I don’t get any jitters or crashes — just a calm, clear mind. It’s helped me stay more mentally sharp, especially when I have a lot on my plate. Whether I’m trying to stay productive, remember tasks, or just focus better throughout the day, Alpha BRAIN really supports that. It promotes memory, focus, and mental processing, and I’ve definitely felt more “in the zone” when I take it regularly. If you’re looking for something to help your brain work better without the side effects of stimulants, this is a solid option!

It’s good to try.

[This review was collected as part of a promotion.] I’ve been taking this since I received it from Influenster. I feel like I could stay focus a bit better for a long session, other than that I can’t tell anything more cuz it’s not too long since I used them.
