Not what I was hoping for...

My brother told me about it and bought two bottles one for himself and one for me. I gave it a shot about two months ago. I took it daily or ever other day just over a month. At first i didn't notice a thing. I figured it needed to build up in the system like some vitamins and mineral. After two weeks I noticed a little bit more clarity in my thought process, but nothing I would say made a major difference in my training or job. I was hoping for something that would push my mental clarity, focus, stamina and energy to a new limit to keep my crushing my day. I train in the gym 5 days a week at 4am for 1.5 - 2 hrs. Then, I work a very physical job as a gutter fabricator/installer, so running up and down 25 ft + ladder everyday with 30 lbs + of tools strapped to me. Then im in dad/husband mode the rest of the day. So, Im always looking for a supplement to give me just a little bit more everything. I keep my diet healthy and clean (no sugar, no processed foods, no alcohol or drugs), so maybe im just at my peak as it is thats why it didnt have my effect on me. It didnt make the cut for me, but in sure it works well for some people.

Best supplement

[This review was collected as part of a promotion.] The Onnit Alpha Brain supplement is a great addition to my routine. I was excited to try it for a week and was pleasantly surprised by the positive effects. I noticed a slight improvement in my focus and mental clarity after using it. The pill is easy to swallow, and the taste is pleasant. The ingredients are also good quality, and the packaging is sleek and attractive. I highly recommend this supplement to anyone looking to improve their mental clarity and focus.

Great for “Mom Brain”

[This review was collected as part of a promotion.] As a new mother, I was struggling with the mental sluggishness that came along with my adorable daughter. I run a business and am also a full time student. I needed to be back to operating at full capacity, and quick! This stuff helps me so much. I feel like I am even better than pre-baby 😀"

Effective and gentle

Alpha Brain Supplements

[This review was collected as part of a promotion.] Was not too familiar with these type of supplements until I received this product! I definitely needed a brain boost and help staying focused! These are easy to take and I honestly have noticed a difference in my memory and focusing. I would recommend these to anyone who could use a little brain support!

Not noticing much change

[This review was collected as part of a promotion.] My brain doesn't feel much different after taking these. I can't say for sure, but my focus and memory feel unchanged. There are only 30 capsules, and one serving is 2 capsules. This means this is only a 15-day supply; that's not a ton. The pills tend to get lodged in my throat even with water. They are relatively tasteless, and the ingredients don't seem all that bad. All in all, I'd rather go for a different approach when it comes to improving my brain function.

Didn't really feel anything

I didn't notice a difference when taking Alpha Brain. I even took 3 one time and didn't notice anything really. It may have provided a benefit in that I did really well on my exams while on Alpha Brain, but to be honest I'm unsure if the Alpha Brain actually helped as I studied pretty hard and prepared. My body is odd though because I've taken painkillers in the past and not felt anything.

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.
