Eh

[This review was collected as part of a promotion.] I honestly don't feel any different. It's a bit of a bigger pill, which could be a problem for some people. It doesn't smell good, that's for sure. I don't know how I'm supposed to feel but I'm not noticing a difference unfortunately.

Okay focus pills

[This review was collected as part of a promotion.] I have tried this for the last few days and the pills are easy to swallow. Not much taste to them. I think they have helped a little with my focus and attention at work and home but they are quite expensive.

Alpha Brain

[This review was collected as part of a promotion.] I received this Onnit Alpha Brain Supplement complimentary from Influenster in exchange for my honest feedback. This supplement helps to support focus, memory, and reaction time. This vitamin is also vegan, gluten free, and caffeine free. Which in time it helps with improvement of memory, focus, and cognitive skills. Directions say to take two capsules a day with a meal but the bottle only comes with 30 that lasts for only two weeks. If you don’t take the vitamins with a meal you will experience nausea and upset stomach. The value is good overall. There is no after taste when taking these pills.

DO NOT TAKE THIS

[This review was collected as part of a promotion.] This is an absolutely horrific product and if I didn’t have to review it I wouldn’t. I THOROUGHLY double and triple checked this product to make sure there were no allergens in this product as I have a SEVERE shellfish allergy. Seeing none I assumed it was safe to consume this product. I was wrong and a few hours later I started having a severe allergic reaction. I thankfully realized what was going on before I went into complete anaphylaxis but I still did miss an entire days work. DO NOT take this product if you have any kind of allergy as they couldn’t be bothered to properly note the allergens on either their website or their packaging. I’ll be pitching this product and advise you avoid it at all costs.

Focus up

[This review was collected as part of a promotion.] Used it for about a week,I think it’s working well I feel way more focused during my day to day , it does not taste like anything ; I pretty much just swallow it with water. The packaging is cool and attractive, the colors get your attention

Very good supplement for brain, memory, and focus.

[This review was collected as part of a promotion.] Ive been taking this @onnit Alpha Brain Helps Support Memory and Focus supplement that i got from @influenster for a while. The bottle looks so nice. After taking it for a while I noticed that my brain/ memory is getting better, i could focus on what i was doing, reading. I used to forget names and faces after i met them couple times, but now i could remember them all, my brain and my memory worked smoother and sharper. The ingredients are friendly to me, I didn’t have any problems with this supplement. Thank you so much @influenster and @onnit for giving me an opportunity to test this product. I definitely will buy it again for myself and my families.

Try this!

[This review was collected as part of a promotion.] I've been trying out Alpha BRAIN for memory and focus, and I wanted to share my thoughts so far. I'm still in the process of using it, but I've already noticed a few things. As someone who struggles with memory, finding something that could potentially help is a big deal for me. One of the first things I noticed is a slight improvement in my focus. I'm able to stay on task a bit longer without getting as easily distracted. It's not a huge change, but definitely noticeable. When it comes to memory, it's still early days, but I feel like I'm retaining information a little better than usual. I'm hoping that with continued use, I'll see even more improvement in this area. Overall, I'm optimistic about Alpha BRAIN. It's not a magic bullet, but it seems to be giving me a little boost in the right direction. I'm planning to keep taking it and see how it goes. For now, if you're looking for something to help with focus and memory, it might be worth giving Alpha BRAIN bt Onnit a shot.

My memory and focus improve tremendously!

[This review was collected as part of a promotion.] As a 37-year-old African American woman balancing life as a full-time teacher and a mom to a young child, mental clarity and focus are essential for me. I started using Alpha Brain hoping for a little boost—and I’ve genuinely noticed a difference. I feel more alert during my lessons, and it’s been easier to stay organized and present, even when the day gets hectic. It’s not a dramatic overnight change, but it helps me feel more on top of things without any crash or jitteriness. For me, it’s become a small but meaningful part of my daily routine !
