[This review was collected as part of a promotion.] I'm not really sure how to feel about it so that makes me think that it's not really doing anything? It obviously has a funky taste just like any vitamin but I'm not really feeling any effects. I don't really have any clarity and I would have no idea how much this cost but I definitely wouldn't purchase this in the future. I gave two stars because it didn't have any negative side effects and maybe the ingredients can help other people just not my brain.

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, if you need further assistance you can always reach out to our Customer Service team at help@onnit.com, they'd be happy to help further! -- Cailee B.

It works!

[This review was collected as part of a promotion.] I was not expecting much from this. After taking it every day for a few weeks now, I DO feel clearer and more focused. It used to take me a few hours to really hone in on a new project, but now I’m able to think about it and dive right in!

Improves memory and cognitive function!

[This review was collected as part of a promotion.] Have you tried Alpha Brain supplements yet? I had the pleasure of trying the famous Joe Rogan supplement for memory improvement and sharpness! Thanks to Influenster for sending me Onnit Alpha Brains supplements for free in exchange for my honest review. It’s one of the most effective supplements for cognitive performance. It supports memory, promotes focus mental processing and flow state. It’s caffeine and gluten free. I really saw improvement especially being a busy mom who is exhausted a lot. It keeps you alert and focused. To be honest I felt sharp and awake like when I drink my morning cup of coffee! I will keep trying it out and see if any changes occur!

[This review was collected as part of a promotion.] Pretty nice vitamin supplement. It helps me a lot with my memory loss and my lack of focus. I take it daily every morning. It doesn’t taste like anything, so you don’t have to worry about a flavor as you swallow. Nicely packaged.

Great ingredients with caffeine

[This review was collected as part of a promotion.] I love me a brain supplement as i tend to forget so much and feel my mind set carry to much to elevate my brain and get things done. I love the natural herbal supplements capsules, i feel they are more effective than compressed pills. I love that it has caffeine and helps you focus and helps with memory. The ingredients are great it contains vitamins B6, L-tyrosine, L-theanine and other great ingredients to be effective.

Placebo?

[This review was collected as part of a promotion.] Got to try these focus pills from onnit and im not syre if they fully helped or had more of a placebo effect on me. I do have times where I can walk away from my desk and forget to finish working, but when I took these i "knew" I needed to focus. I did get more done, but not a huge jump in productivity.

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 to receive the full benefits! Please feel free to reach out to our customer service team if you have any questions!

Get it!

[This review was collected as part of a promotion.] Thank you influenster and Alpha BRAIN. My husband and myself have felt improvement in our daily routine. We’re more alert and focused. We’re a family of seven so we’re always on our toes with our children. I recommend having a decent meal with water before taking the vitamin. If you don’t, you may experience stomach aches. The colors on the bottle are eye catching. Some of the ingredients in this supplement are L-THEANINE, ALPHA GPC, HUPERZIA SERRATA EXTRACT, and VITAMIN B6. The supplement is also caffeine free and gluten free! I included a picture of the nutritional label for more additional information. There’s no bad taste to this vitamin. I recommend this supplement in your daily routine!
