Brain food

[This review was collected as part of a promotion.] This product is difficult to review probably because results depend on your brain health in general. I didn’t notice any major change on my focus. What I find it is the packaging is pleasing. The product is easy to take and digest and does not leave any aftertaste. I will continue using it and see if it makes a difference.

Feeling settled

After months of feeling off, this changed the game. My mind kept spiraling therefore my feeling were, too. Within 40 minutes of taking the first pills I noticed a pivot. Mentally and emotionally, it was sooo amazing. I felt more at ease and calmer. But not calmer like when you feel lazy, nah, the opposite, you want to rule your day and are focused about it.

Life-Changing Focus and Clarity!

[This review was collected as part of a promotion.] I’ve been using Onnit Alpha Brain for a few weeks now, and the results have honestly exceeded my expectations. Within the first few days, I noticed a boost in my mental clarity, focus, and memory recall. Tasks that usually felt overwhelming became more manageable, and I found myself getting into a productive flow state much more easily. What I love most is that it’s stimulant-free, so I don’t get any of the jitters or crashes I’ve experienced with other nootropics or energy supplements. I feel sharp, alert, and clear-headed—without sacrificing calmness. The ingredients are clean and well-researched, and I appreciate that Onnit takes the time to back their formula with science. I take Alpha Brain before work or creative sessions, and it’s become a staple in my daily routine. If you’re looking for a natural way to boost brain function and mental performance, I highly recommend Alpha Brain. It’s worth every penny!

Not again.

[This review was collected as part of a promotion.] After finally finishing this bottle. I can say I’m not a fan anymore. At first it was very helpful maybe it was just something I got used too but I definitely wouldn’t recommend if it happened that fast. Taste was okay it didn’t taste like anything and it’s a good value for the capsules but it was not effective.

An excellent choice for memory and focus!

[This review was collected as part of a promotion.] Packaging is bold and stands out. No taste and capsules are easy to swallow. I love that the formula is caffeine free. This allows for more flexibility on how late in rhe day I can take this supplement.

Subtle focus boost

[This review was collected as part of a promotion.] I’ve been taking Alpha Brain for about 3 weeks now, and I can honestly say I notice a difference. Within the first few days, I didn’t feel much, but by week 2, I noticed I was staying more alert and organized. I could remember small things better, and I wasn’t zoning out as much. It’s not like caffeine where you feel a “kick”—it’s more subtle, like your brain just works a little smoother. I didn’t get any weird side effects. No jitters, no crashes, and no trouble sleeping. I even felt slightly more creative when brainstorming.

Unsure about the ingredients

[This review was collected as part of a promotion.] I tried the product for 2 weeks. So far, I haven’t seen any significant improvement on my memory and focus. I am, however, constantly worried about the legit of the product tho. The ingredient table is full of ingredients that I have never heard of, and it makes me feel like I am a guinea pig for a supplement created by an influencer

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!

This is great

[This review was collected as part of a promotion.] I was given this product for free in exchange for an honest review. I’ve been taking this for a few weeks now and notice some difference in my focus and improved memory. I can’t wait to see the results after a month!

Hard to say…

[This review was collected as part of a promotion.] It’s hard to say if this product helped me or not but I want to believe it did…it has ingredients I’ve never heard of like phosphatidylserine and ingredients I know we’ll like l-theanine and vitamin B6, so I am not really sure what everything really did…packaging could be smaller for the amount of product inside…

Maximum Brainpower

[This review was collected as part of a promotion.] I’ve been using Onnit Alpha Brain for a few weeks now, and I have to say, I’m liking it. This nootropic supplement has really helped improve my focus, mental clarity, and overall cognitive function. I work overnights in a low stimulation kind of job and it can be kind of drag. This definitely helps the night go by a bit better. I like that it doesn’t give me the jittery or crash feeling that some other supplements can. I would highly recommend it to anyone looking to boost their brain power, whether you're in a high-pressure job, studying, or just looking to stay sharp. It’s definitely a nice mental boost! @influenster #complimentary @onnit #getonnit
