Give time for them to take effect.

[This review was collected as part of a promotion.] I’ve gotten to test these Onnit supplements that are to help focus, support better memory and just help give a little extra boost. I will say, I believe that I’m still in the process of my body getting used to the tablet and it does seem to help with the memory fog a bit so I will continue to take them and update after a few more weeks. Ingredient wise, it seems that the tablets are packed with a lot of good vitamins. I would take precautions if you’re already taking supplements (just not to get some vitamins way above the threshold) but no nasty taste and pretty easy to swallow.

Works for me

I purchased Alpha Brain in order to sharpen my focus while I do estimates for my construction company. For those of you who bid work, you know how painful mistakes can be. I didn't think it was working until I realized that I do about 50% more estimates while taking Alpha Brain as when I don't. I don't get a buzz or anything like that but I am obviously more focused based on my productivity. Thumbs up

My brain is now Alpha

[This review was collected as part of a promotion.] The concept of this supplement is really cool. It helps you focus without caffeine. Making you an alpha. Or as my kids would say, sigma. The packaging is great. Standard vitamin packaging, but using a dark bottle. Which I’m guessing keeps everything fresh. If you want to have the brain of an alpha, or just better mental clarity and focus, this is for you.

I loved

[This review was collected as part of a promotion.] I’ve been using Alpha BRAIN by Onnit for the past few weeks and honestly, I’m impressed. I’ve noticed a real difference in my ability to stay focused and clear-headed, especially on busy or mentally draining days. It’s not some magic pill, but it definitely gives me that extra mental edge — whether I’m working, planning, or just trying to stay sharp. Also feels like my memory recall and reaction time have improved a bit too. Definitely staying in my routine for now.

Easy to take no unpleasant side effects

[This review was collected as part of a promotion.] This alpha brain daily cognitive support supplements really help support memory and focus for me. I like that you only take 2 a day and it lasts all day. There are no bad side effects after I take them.

Love it

[This review was collected as part of a promotion.] I’m a mom of three and my brain is always tired. Alpha Brain helped me feel more focused and clear during the day. It’s not magic, but it does make a difference. I only take it when I’ve had some rest — otherwise, it can feel a bit strong. Great for busy, tired moms like me!

Onnit alpha brain

[This review was collected as part of a promotion.] Received this Onnit Alpha brain supplement to try out complimentary of influenster. Bottle only comes with 30 capsules and directions are take 2 daily. That means I only used for 15 days and really not enough to see it truly works, unfortunately. Did not have any bad side effects, easy to swallow, no after taste. Would have needed to try out for at least 2 to 3 months sadly not enough product.

saved my butt!

I bought this initially for the dream state aspect, but when I took it the first time it made me way more creative on the bass. I actually made something instead of just playing what the greats do. The dreams are pretty fun too. I take this before my wednesday classes at Central Michigan University because I'm learning from 2 to 7:30 so I need the focus. I recently had an exam and the info that I retained from taking alpha brain literally saved my butt from failing. Wish it was cheaper so I could give it to some college students to try it!

Pretty helpful

[This review was collected as part of a promotion.] So far, this feels effective. The taste isn't too bad, and the ingredients are great. It has a vegetarian capsule, so it could appeal to those who do not use meat based products.the label gives all the info needed. So far, I like them !
