Focus Flair

[This review was collected as part of a promotion.] I was gifted this product in exchange for my honest review but all opinions are my own. I was initially a little worried by the size of the supplement, but it went down easily and didn’t upset my stomach. I tried it with coffee and without, and definitely felt like with a cup of coffee it was a good combo.

Brain focus and helps a good amount

[This review was collected as part of a promotion.] Would take alone in days you need focus and get things done has helped a great amount when taken with other vitamins cause cause mind to spiral or stomachaches but nothing extreme I’m a big fan of the packaging simple and neutral tones won’t look hideous next to other things

Brain power

[This review was collected as part of a promotion.] Easy to read packaging. I believe that they do help with some mental focus. I only took them on days I was needing a little extra at work. I didn’t “taste” them, I just swallowed the pills and moved on. I would recommend

Focus on you

[This review was collected as part of a promotion.] I received this product from influenster and Alpha Brain for my honest review. Added this vitamin to my daily intake and worked immediately. I drank it with lots of water and next thing I knew my will to focus was better and I felt great. I do reccommend drinking lots of water as it can make you feel a bit dehydrated.

help memory

[This review was collected as part of a promotion.] If you're like me after having kids and getting older ,you're forgetting things and not staying as focused as you were years ago. This is what you have been looking for, skip the energy drinks and the crashing effects of other supplements, THIS right here is ALL you need! This helps support memory loss, promotes focus, promotes mental processing, and helps you feel like you're in the ZONE. This is a caffeine free product. I've been taking this for a week and a half now, and I noticed a difference the first day I took it. I highly recommend switching to this product.

Booster for focus

[This review was collected as part of a promotion.] As a techie, I spend a lot of time on screens. I tried Onnit Alpha Brain capsules with breakfast, and they moderately boosted my focus and senses. While not groundbreaking, it reduced my need for coffee. Occasionally, I experienced mild headaches, but nothing alarming.

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!

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 .

Improves Performance - must take with a heavy meal

[This review was collected as part of a promotion.] The AlphaBrain vitamins are small and easy to use. I would recommend taking these with a heavy meal, as not doing so made me quite sick. The product did work for me and gave a boost I needed throughout the work day.
