Great brain booster

[This review was collected as part of a promotion.] I really like that this supplement works for helping me stay focused without having to use caffeine, which I already get enough of. It's very nice to have a supplement that also helps with memory so I feel like I'm doing my best to keep my brain vibrant and healthy. The capsules themselves are fairly easy to swallow with water, as they're what I see as an average size.

Great daily cognitive support!

[This review was collected as part of a promotion.] Onnit Alpha Brain is a standout dietary supplement that has enhanced my focus and mental clarity. I did not notice any difference right away so I continued to take them. However, after several days the cognitive boost and improved memory recall were noticeable. The capsules are easy to take, and I also appreciate the natural ingredients. If you're looking for a supplement to sharpen your mind, Alpha Brain is worth trying!

Brain help

[This review was collected as part of a promotion.] Love that it helps with the brain & memory something I tend to need help with. They don’t leave a nasty vitamin taste which i love. You take 2 capsules daily & it comes with 30 pills so a 2 week supply.

My personal experience

I’ve been taking nootropics for a while now and I was excited to try the highly recommended alpha brain, ordered it on subscription base to get a discount and mostly because I figured it was a good supplement due to all the reviews, the first day I took two capsule which is the recommended dose and I felt pretty alright, went and worked out and felt fine, then afterwards started to feel nauseous and dizzy, and it felt like my head was getting hot, had to lie down for a while. Figured it was something else, then the next day I took two capsule again with food and 30 min later I felt nauseous and dizzy again, and really out of it. The next day I didn’t take it at all and I felt fine, THEN the day after that I took only one capsule and felt sick again, for some reason this stuff makes me feel sick and the only focus I had was on not dying lol. Maybe it’s just me though, according to most of the reviews this product works great. Just not for me I guess

[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.

No smell, no taste

[This review was collected as part of a promotion.] I’m gonna take those vitamins for about a month and I have not seen any significant improvement in my brain functionality. Not sure if I just need more time or is it just doesn’t work . On the positive side the pills are nice size and easy to swallow with no unpleasant smell or taste.

No Adverse Effects

[This review was collected as part of a promotion.] Alpha Brain Supplements from Onnit Labs have Vitamin B6, amino acids, and other herbal extracts that help with memory. My memory has suffered as I age. You take 2 capsules a day with a meal. I can’t really tell whether they are working yet but I have not had any adverse effects. I look forward to seeing the improvement to my mental clarity by continued use.

Alpha brain review

[This review was collected as part of a promotion.] Thanks influenster for sending me Alpha brain supplements in exchange of my honest review. Alpha Brain definitely helps me maintain focus and gives a good energy boost. I'll continue to buy it. No negative side effects for me and definitely helps me focus and get work done. Normally I’m very easily sidetracked but not anymore! Start a task-end a task.

Really Works!

At first I couldn’t really tell, but after taking it regularly a couple of days I started to notice my mental math was not only more accurate it was actually quicker, it honestly surprised me. I do plan on adding this supplement as a staple to my daily routine.
