Good ingredients

[This review was collected as part of a promotion.] I’m pretty skeptical on supplements so I can’t trust it in just a month of trying it, however I do like the ingredients in it. It has no taste which I like, I do feel more clarity but I don’t know if it is from it yet or just knowing I’m taking in good ingredients. Will be trying out for a couple more months

reply from Onnit Customer Service

Thanks for reaching out and leaving a review! So sorry to hear that Alpha Brain did not work for you. Because everyone reacts differently to supplementation 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 - sometimes it can take time to notice these effects. That being said, if you are ever dissatisfied with your order, you can always contact our Customer Service team for further assistance!

Caused loss of ability to speak and motor function

About an hour after I took the two capsules (as instructed by Onnit), I thought I needed to go to the hospital. I was trying to articulate something to my husband, and I could barely form a sentence (beyond frightening all on its own). Shortly after, muscles all over my body started to periodically twitch to the point where I needed to lay down in fetal position. When I tried to stand and walk, the effort felt enormous and I was afraid I would collapse. I eventually also experienced nausea. In a panic I researched reviews on the product and found many on various websites that said they experienced the same thing and that it will eventually subside, which is the only reason I didn't make my husband drive me to the ER. Instead of having the productive day I expected, I spent it trying to sleep it off. I'm not going to knock brain supplements because most are excellent, but the particular blend in Alpha Brain is extremely dangerous. If it were only myself that had this experience, I wouldn't say this, but the amount of people who are saying they had the same reaction is unacceptable. I do NOT recommend this product- what happened to me and many others is not normal, it's disabling and unsafe.

Takes time

[This review was collected as part of a promotion.] This product works but it takes time to work. It's best if you take it every day for the effects to work with your body. It calms your mind when you're busy so that way you focus on one thing at a time. The taste isn't bad and no funny after taste.

Okay

[This review was collected as part of a promotion.] I recently tried ONNIT Alpha Brain, and I have to say, I'm impressed! This dietary supplement is designed to support memory and focus, and I definitely noticed a difference during my daily tasks. The capsules are easy to swallow, and I appreciated that they contain natural ingredients. After taking Alpha Brain for a few weeks, I felt more alert and able to concentrate for longer periods. It seemed to help with my clarity of thought, especially when I was working on complex projects. I also liked that it didn't give me the jittery feeling that some energy supplements do. Overall, I would recommend ONNIT Alpha Brain to anyone looking to enhance their cognitive function in a natural way!

Great ingredients with caffeine

[This review was collected as part of a promotion.] I love me a brain supplement as i tend to forget so much and feel my mind set carry to much to elevate my brain and get things done. I love the natural herbal supplements capsules, i feel they are more effective than compressed pills. I love that it has caffeine and helps you focus and helps with memory. The ingredients are great it contains vitamins B6, L-tyrosine, L-theanine and other great ingredients to be effective.

Boost Your Focus and Memory with Alpha BRAIN

[This review was collected as part of a promotion.] I’ve always been looking for a way to improve my focus and memory, as my daily life is filled with tasks and responsibilities that require maximum concentration. That’s why I decided to try Onnit Alpha BRAIN, and so far, I’m very satisfied with its effects. Since incorporating it into my routine, I’ve noticed greater mental clarity and better performance in my daily activities. I love that its formula is caffeine-free and that its ingredients are designed to naturally optimize cognitive function. I had high expectations because I needed real support to boost my productivity, and I feel that Alpha BRAIN is helping me stay focused and organized. I will definitely continue using it.

WORKS!

[This review was collected as part of a promotion.] I can honestly say that I feel more focused and mentally prepared for the day after taking this supplement for over a month. I would and did buy more to keep it in my body. Wish they had a jumbo bottle haha.

Great product

[This review was collected as part of a promotion.] This is such a great product in theory but I’m not sure if it states what it says it does. So far I haven’t noticed anything different aside from taking the supplement but maybe I just have to give my body some time to adjust to it.
