Supercharger for my Brain

I work in a busy automotive repair business and my days are filled with really complex problems to solve. Alpha Brain helps me smash through road blocks and continue to work through technical issues to find a solution for my customers and team mates.

Not worth the money

[This review was collected as part of a promotion.] I in all honesty did not notice any difference and for the price of this product I really don’t think it’s worth it. It’s your average packing. The ingredients seem OK but I honestly don’t think this product works. They’re far better supplements for the money that they want for this.

Disappointed

I originally purchased this due to its advertisement and who endorsed this product. Even though I had high expectations, I felt the exact opposite affect than what was advertised. I felt cloudy, tired, distracted. It was the feeling that I was just waking up but this feeling did not go away, and was with me all day until this wore off in the afternoon. I am not sure if this was just because I did not give the Alpha Brain enough time to work, but enduring this anymore than two days would have put me at a disadvantage at work, which is not something that I can let happen. I would be curious to see why I was feeling these affects and if there would be anything that I could do differently in order to feel the affects of the advertised product.

Alpha BRAIN® boosts focus, clarity, and memory wit

[This review was collected as part of a promotion.] Alpha BRAIN® by Onnit has been a great addition to my daily routine. After a few days of consistent use, I noticed improved mental clarity and better focus during work and study sessions. It helped me stay sharp without any jitters or crashes, unlike some caffeinated alternatives. I also felt a subtle boost in memory retention and quicker reaction times. It’s a solid supplement for anyone looking to enhance cognitive performance naturally and stay on top of their mental game.

Interesting

[This review was collected as part of a promotion.] Gifted by Onnit & Influenster. Haven't tried these yet. Three kids in, mommy brain kicks in, and this is most helpful indeed. So much goes on. All at once or just in general, keeping track of everything and everyone. So many need my attention and focus.

Memory focus

[This review was collected as part of a promotion.] Review of Onnit Alpha Brain – Memory & Focus Onnit Alpha Brain is a popular nootropic supplement designed to enhance memory, focus, and cognitive function. After trying it, I noticed a slight improvement in mental clarity and concentration, especially during busy workdays. The blend of ingredients like Bacopa Monnieri and Alpha-GPC seems to provide a mild but noticeable boost in processing speed and recall. However, the effects aren’t instant or dramatic—it's more of a subtle enhancement over time. Some users may experience mild side effects like headaches or digestive discomfort, but I didn’t have any issues. While it’s a solid option for those looking to optimize mental performance, the price may be a concern for long-term use.

Sharper focus, more stamina !

[This review was collected as part of a promotion.] I received complimentary Alpha BRAIN by Onnit in exchange for my honest review. My husband has been wanting to try this supplement for a while so we both tested it. This product is awesome. It really helped me focus and move with ease finishing one task after another instead of my regular neurodivergent way of starting something then multitasking to the point I don’t even know where I started. I missed a couple days because I wasn’t feeling well and really noticed a difference in my lack of concentration, energy and over all mood. This product really helps me stay positive and in the moment with my young children as well. My husband loves this product. He has a stressful labor intense mentally challenging job, and after we finished our complimentary bottle he bought more in bulk. It’s THAT helpful at helping him navigate through his tasks.

Dreams improved 100%!!!

[This review was collected as part of a promotion.] I was incentivized with this complimentary item by Influenster and Onnit in exchanged for my honest review. I was shocked how much I was going to like these capsules. After I started taking them, my boyfriend asked how I liked them because he had heard Joe Rogan rave about Onnit on his podcast. I told him that although it does make my heart beat a lot faster at resting times, I was astonished about the affect it had on my dreams!!! Usually my dreams are cloudy or hazy and never make any sense. They are discombobulated and things morph from one thing to another. After taking this (1st night), my dreams were so clear visually as well as things were slowed down like as if I was watching a movie I had seen before and knew what was coming next. I rarely have lucid dreams but I felt very much in control of these ones. In turn, when I woke up, I felt much more relaxed and well rested. I took these pills with dinner so this reaction might correlate to them still being in my system when I went to bed. I’m going to try another bottle but this time, I’m going to take them in the morning and see if my dreams are as clear.

Don't be scared to try

[This review was collected as part of a promotion.] I take two of these in the morning every morning and they really do sharpen me up for the entire day. I feel more energetic and focused. I definitely notice an increase in my cognitive abilities. I can process information quicker and have a much easier time articulating myself in verbal conversations. It has increased my productivity at work by a noticeable amount. It kind of has the same effect as caffeine but without the jittery wired feeling I get when I drink coffee or an energy drink.

Not onnit

[This review was collected as part of a promotion.] I received this from Influenster for my review. First item that made me instantly sick and thought I’d have to go to ER. Took about a half day to feel back to normal after trying to rid it from my body.
