Helped me stay on task

[This review was collected as part of a promotion.] This product surprised me. It is very effective helping me stay more focused and on task. The ingredients are safe. It doesn’t have an aftertaste. Easy to handle. It is definitely worth a try for those that tend to jump from one thing to another without finishing anything really!

Natural, stimulant-free focus

[This review was collected as part of a promotion.] I received Onnit Alpha BRAIN supplements from Influenster to review. They are being modeled by my sun Bushy 🌞😺 but they are strictly for human use only. I've been taking Onnit Alpha BRAIN supplements for a few weeks and have noticed some improved focus and mental clarity. I like that it helps me stay sharp without the jittery feeling that often comes with drinking caffeine. It’s also nice that it's stimulant-free and made with natural ingredients. The capsules are a tad large, and it's a little pricey, so the suggested two capsules a day from a bottle of 30 capsules only covers about 2 weeks but overall, it seems to be a decent product.

Alpha Brain works great at improving mental clarity and focus

[This review was collected as part of a promotion.] Onnit Alpha Brain works great at improving cognitive focus and function. Increases memory and focus. Promotes mental clarity and productivity as well. It takes about a hour or two to kick in and start working. If you’re looking for a boost in mental clarity and focus I’d suggest giving these a try.

It does nothing for me.

I've been taking Alpha Brain for over a week and it could be a placebo for all I know. I don't notice any changes in mental speed or clarity, memory or . . . anything. I went in open minded and I really wanted to like and trust this product, but I just don't feel anything whatsoever from it. And it's ridiculously expensive for nothing pills.

Great but a little pricey

[This review was collected as part of a promotion.] Its actually considered a good product. It has no taste and odor when you take it. It actually support my brain. I stay awake in the morning without coffee because of it. So i think it works. However, it think it is alittle pricey when it comes to supplement. Overall 4/5z

Okay so far!

[This review was collected as part of a promotion.] I’m not sure if they are really working but they make me feel more energized and there is a lot in the bottle. There is no taste so that’s a good thing, I would have to use longer to see actual results.

Clearer focus!

[This review was collected as part of a promotion.] These capsules really seem to give me energy in the morning since starting these! I can tell a difference- I am a 34 year old woman who is active but has fallen into a slump of low energy- but since taking these I am not falling asleep at work. As of right now, I’d recommend this to anyone looking to boost overall daily performance.

Caffeine free

[This review was collected as part of a promotion.] One of the standout benefits is the improvement in my memory recall I feel more clear-headed and able to retain information better. I also appreciate that it’s made with natural ingredients and is caffeine-free, making it a great option for daily use.

Helps with Focus

[This review was collected as part of a promotion.] I feel like it’s not as effective as I’d want. This could be my fault because I forgot to take daily. So if it needs to be taken consistently that’s on me. I could tell a small difference but for the price I would expect it to better. Taste free and great quality ingredients!

Thanks for taking the time to share your experience! We're sorry to hear that Alpha Brain wasn't the right fit for you. It's expected that we have a range of responses since supplementation is not one size fits all. Sometimes it can take a few tries to notice these effects. Experimentation is key! That being said, we would never want you to feel stuck with a product that didn't meet your expectations, and if you reach out to our Customer Service team, they'd be happy to help further!

No Difference

[This review was collected as part of a promotion.] I’ve been taking these daily for over a week now. I haven’t felt or noticed any difference. The packaging is nice and I’m sure it’s a great product for some people, but it definitely doesn’t work for me.

Thanks for giving Alpha Brain a shot and for sharing your experience! Everyone's experience can be a bit different with a formula like this. It's formulated to help support memory, focus, and processing speed, and it can take some regular use to really feel these changes. We suggest trying it for at least two weeks and if you still aren’t happy we can help with some supplement tips and/or to help facilitate a return if needed. You can email help@onnit.com for further assistance with your order!
