Engaging in conversations with great focus!

I started simple...taking one in the morning. Just to see how it would affect me. I was cleared headed, speaking more eloquently, and engaging in conversations with people much more intelligent than me and holding my own in the conversation! I started taking more in the afternoon and experienced some very interesting dreams as well.

Alpha Brain Is Next Level

Dude. I can catch everything, my whiskey fell off the top of my fridge and I caught that and prevented a bottle from breaking without even realizing what I was doing. Locked in at all times, and I’m better at video games. Totally worth all the money.

Couldn’t get past the vitamin smell and taste

[This review was collected as part of a promotion.] Unfortunately I couldn’t get past the smell of these to use them regularly. Vitamins and supplements are hard for me to take due to the taste and smell and these were the same. I was really looking forward to trying, but just wasn’t able to.

Thanks for leaving a review about your experience with Alpha Brain! We’re bummed to hear that you didn’t have the experience that you were hoping for. Being that we all have different needs, it's expected that we all respond to supplements a bit differently, and we're glad you gave it a shot. -- Cailee B. ONNIT Customer Service Associate #getonnit

Alpha Brain is incredible!

Alpha brain has changed the game. I am sharper, more alive, more aware, and more in tune with my surroundings and my responsibilities. I am a drummer, and Alpha Brain has taken my playing to the next level. My shows have never been better.My precision has increased dramatically. I know 100% that it's not placebo. This supplement is expensive.... but well worth it in my opinion. If you are on the fence, give it a try!

The love of my life!

Love this stuff!!! The clarity to problem solve is amazing! My house is really clean and I’m more organized. I’m a 73 woman and feeling 30 years younger! I’m trying to convince everyone I know to try it and giving out samples. My 75 year old husband sees a real difference in concentration when he shoots trap.! For Pete sake just this stuff! Also upgraded to Total human!

Sudden hot flashes

Definitely felt more productive after starting but then I suddenly was having hot flashes that came and went about 10 in a 24 hour period. I’m 49 so I just thought that I was starting menopause but when I stopped taking the Alpha Brain they went away but it took about 3 days. Haven’t had any hot flashes since then. Maybe it’s a coincidence but I’m not going to take them again and find out because hot flashes suck.

Effectiveness

Joe Rogan put me on to this. No lift off. No drop. Focus. Appetite suppression. Very mild but effective. I recently got sober and my productivity over the last 2 months have been 2x-3x. Even started working out again. Mood enhancer but mild. Better overall thoughts. Healthier thinking. Will be purchasing more.

No energy change, but definitely a change overall

I was hesitant at first but am definitely pleased. The product at first seemed like there was no jolt or change in my energy. I continued to take it 2 weeks in I was losing weight with little to no change really. Then the mental processing and motivation to do stuff changed. Now don’t get me wrong, I still had no amp up in energy but I was focused on whatever task was in front of me and determined to get it done. Definitely keeps you going.

Really wanted this to work!

Honestly I never really felt a difference. I really wanted to give this a shot. I work full time and go to school full time s I’m very busy and could of used some energy and focus. I just didn’t get what I was looking for. Hopefully you have another product that could help.

We appreciate you taking the time to leave some feedback! Sorry to hear that Alpha Brain Instant didn't benefit you. Every person reacts differently to supplementation, and 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 - and we recommend giving it a full two weeks. That being said, if you are ever dissatisfied with your order, you can always contact our support team for further assistance!

Its ok , thanks

[This review was collected as part of a promotion.] I’ve been using Alpha BRAIN and noticed improved focus and mental clarity without feeling jittery. It helps me stay alert and productive throughout the day. Easy to take and works well for daily use. Easy use and after drink its ok no problem
