Alpha brain supplement

[This review was collected as part of a promotion.] I took these for about a week and I did notice that I felt more alert at work. It was a nice feeling. I feel like I would buy these again and keep taking them to see how they are long term. They are a good value the ingredients are good, and the pills were easy to swallow with no taste/after taste.

It is advisable to attempt.

[This review was collected as part of a promotion.] The product's packaging is aesthetically pleasing, featuring a combination of black and gold accents and clear labeling. While dietary supplements can have varying degrees of effectiveness, I did not personally experience significant benefits from this particular product. I prefer supplements that are tasteless, and while the ingredients in this product are of good quality, the price point is somewhat high.

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!

👎🏽

[This review was collected as part of a promotion.] I had high hopes for Onnit Alpha Brain, but unfortunately, it didn’t work out for me. After just a few days of use, I started experiencing severe headaches and nausea, which only got worse the longer I took it. Instead of boosting my cognitive function as advertised, it left me feeling drained and on edge. I tried reducing the dosage, but the side effects persisted. For the price and the promises, I expected much better results. Sadly, this supplement did more harm than good for me. Would not recommend.

Brain Boost

[This review was collected as part of a promotion.] I’ve been using Alpha BRAIN for a few weeks and noticed better focus and mental clarity, especially without the jitters since it’s caffeine-free. It’s a bit pricey and doesn’t list exact ingredient amounts, but it’s been a solid boost on busy days.

Not for me

[This review was collected as part of a promotion.] When this finally came in, I waited for the following day to take it so that I had plenty of time to try it out before going to bed. At first, I didn’t feel any difference. It’s easy to take. 2 pills a day with a light meal. I only took 1 to see how I would feel. Again, I didn’t feel anything. So I did a second day. My eyes started twitching. It was like that all day and all night. I stopped taking it to reset my body. I even made sure to get plenty of sleep. And eventually it got better. I figured I would give it a try again. And yet again, it made my eyes start twitching. I’m not for sure what is going on. But I’ve never had problems with my eyes before. And I had researched the ingredients before taking it. And it seemed like they were fine. I hope this works for others. But It’s definitely not for me.

Great focus and productive!

[This review was collected as part of a promotion.] This is the first time I've tried Alpha Brain after hearing about it from so many people. I absolutely am having a great experience with it. My focus is fantastic. I feel great, and am getting everything done in a timely manner. I highly recommend this. Using instead of an energy drink.

Really works !!

[This review was collected as part of a promotion.] I had heard great things about this product before so I was excited to try it. I really liked the fact that it helps you concentrate and anything that helps support memory is a must for me ! There are so many reasons to try this and I really think you’d enjoy !!

2 week supply

[This review was collected as part of a promotion.] It’s hard to know how effective these pills really are because they only last for two weeks. You have to take two pills a day so this is a very expensive package for you to be taking consistently. I do like that they don’t include caffeine in the ingredients list.

Great supplement!

[This review was collected as part of a promotion.] This is a great product if you are looking for a supplement to help you focus more! I’m not gonna lie, the pills are a bit large, but if you can get past that, this supplement has helped me with focus and memory. I love the daily nootropic formula because it assists me with my mental clarity and helps me get in the zone to focus to increase my cognitive processing speed! Recommend!

Not for me

[This review was collected as part of a promotion.] I can't say this was particularly effective for me. Everyone is different and for me, it made me feel sick. The ingredients seem good and there was no weird taste. A decent value and the packaging was good. But I couldn't take it past the first day due to feeling sick.
