Good brain supplement

[This review was collected as part of a promotion.] I’m so happy to get this brain supplement to support my brain. It contains 30 capsules for 30 days. To me, this capsule is a little bit bigger than others, so considering to take a lot of water. It’s taste ok, not as much hard.

You have to understand your body

All people that say that they got sick is very understandable. When you take alpha brain, the compounds clean your body from all the bad things and the body immediately goes into safe mode so it shuts some things down, thats why you lose energy and get tired because the body needs that energy to clean your body, just like it happens when you get fever. Aha! So... what you should have done is just to continued to take them and I know for some people its not easy but thats just the way you have to do to get clean if you had some rough years...

great supplement

[This review was collected as part of a promotion.] I was very skeptical about the claims when I first tried it, but I'm a full believer now. I feel more focused and calm. A great supplement for busy people who could use some improved focus and memory.

Seems like a lot of hype

Genius marketing and incredible website sold me on it but the product did not deliver. Been taking it for a week and I'm very disappointed, all this did was give me multiple unpleasant dreams that were slightly easier to recall. Snack on walnuts and blueberries for the mind, get into meditation for enhanced dreaming. Thought this would be a nice addition but it was not.

Surprised with the result

[This review was collected as part of a promotion.] I don’t trust magic pills that help you focus or give you energy. But they have surprised me, I have already been taking them for two weeks and I think they have made a lot of difference, they help me to hang myself in what I do during the day and to rest at night, they do not have any strange flavor, and their ingredients are fine.

Good

[This review was collected as part of a promotion.] Works as described - hard to put it into words exactly, but I would say it definitely makes me more alert during the day without being overwhelming. It took maybe 1-2 weeks before the effects weren't distracting, but now that I'm used to it, I can definitely see myself keep taking it. Bonus is that it helped me move away from drinking coffee, which was something I had been trying to quit for a while.

Too soon to judge, for me

Started in August and didn’t notice any significant improvements, so took a pause when the bottle finished in the hope that when I decide to continue (now), I’ll be able to notice a change. Have an order for 3 bottles, roughly 3-months, so I’ll know more then.

Thanks for giving Alpha Brain a shot and for sharing your experience! Everyone's experience can be a bit different with a formula like this. It's formulated to help support memory, focus, and processing speed, and it can take some regular use to really feel these changes. We suggest trying it for at least two weeks and if you still aren’t happy we can help with some supplement tips and/or to help facilitate a return if needed. You can email help@onnit.com for further assistance with your order!

Seems to be working

[This review was collected as part of a promotion.] I've been taking this for a little while now and I have noticed a difference in my ability to focus on things for longer periods of time. I usually get distracted easily. I'm gonna keep taking it for a while to see how much more improvement I can see.

Verdict is still out.

[This review was collected as part of a promotion.] The verdict is still out here. Tried out for the first time last week. Honestly? I dont feel a big difference yet. But not every supplement kicks in right away, and I know consistency matters. I’m giving it some time and seeing how it fits into my routine. I'm keeping up the hope!

May help

[This review was collected as part of a promotion.] This supplement actually does help you focus. I was surprised when I noticed how I was going through my day at ease and with an open mind. It’s capsules that you can take every morning to really get your mind into things.
