Great for focus

[This review was collected as part of a promotion.] I got to try Onnit Alpha BRAIN thanks to Influenster, and I’m really impressed! It helps with focus, mental clarity, and memory without any jitters or crashes. I feel more alert and can concentrate better throughout the day. If you’re looking for a natural way to boost your brainpower, I’d definitely recommend giving it a try!

[This review was collected as part of a promotion.] @influenster @onnit #complimentary #AlphaBRAIN #CognitiveEnhancement #Focus #GetOnnit Excellent product. I have been taking it for 6 months now. The craving for sweets has disappeared, the skin has become clean, smooth, and I definitely have more energy.

It works

I bought about a month ago. I am a 50 year old. I run moderately. I took the product religiously for the first ten days. While running I noticed my focus very in tuned. I stopped taking and started to watch my mind wonder as I was on my runs. About 4 days of getting back on Alpha Brain, my focus is back and longer runs are possible. Thank you.

Worked a little bit - but not for me

[This review was collected as part of a promotion.] Received a bottle of Onnit Alpha Brain to review courtesy of Influenster. The packing was nice. Aesthetically pleasing. Bottle was easy to read and not overloaded with information. Dosage, ingredients and general info; typical and standard but color and text was nice. Looked like a good bottle. The product itself, I'm not too sure. It supposedly is supposed to support improved focus and mental clarity. I'm not too sure if it could have been placebo as I did feel a little bit more focused, alert and clear-headed after taking. However the effects didn't last too long and after regular use, I didn't see too much of a difference. I do however acknowledge that there are many other factors that influences how noticeble effects could be. On days that I particularly needed mental performance, it seemed to help somewhat. On days I didn't - didnt know any major effects. If anything, it may have been more subtle. Overall, nothing life changing. Helped to concentrate on tasks and be more focused with less distractions. I did feel like maybe it helped with memory. I was studying for some exams and while taking this product, I felt like I was able to recall more information more than usual. But again, that could have possibly been a coincidence. I didn't see too much of an energy boost but I did feel less tired than normal. I did feel like my sleep quality was improving whole taking this product. Overall, I feel like this product may have worked but not like I was hoping it would. Perhaps it would work on others more sensitive to the ingredients and or others that metabolizes the product in a different way. For me, it was nice to try but the value was not there. I didn't notice any major benefits that would justify using this regularly or paying for it. However, I would recommend to try it and see for yourself on how useful it may be!

Your changes killed your product

We started purchasing and using Alpha Brain 3 or 4 years ago, and we found it extremely beneficial. A bit over a year ago, you announced that you had changed the formula. Well, ever since then, we've noticed no benefit from it whatsoever, and will no longer purchase your product.

Helps clear my mind

[This review was collected as part of a promotion.] (I received this item free in exchange for an honest review) I like the packaging. It’s straightforward and to the point. there is no taste and I would say it started working after about 30 minutes. I took it with a small meal as recommended. As far as the experience, for me it gave me a clear mind feeling which I appreciated as someone with rushing thoughts constantly. Otherwise I didn’t really feel any different. I can’t say if it helped me focus tbh but I still like it. I took it more to help me remember things.

Small capsules packing a mighty punch

[This review was collected as part of a promotion.] These small capsules pack quite a punch. The ingredients are healthy and the packaging is perfect. I find myself to be more focused when I take these capsules. I have not experienced any side effects after taking these capsules

Nice

[This review was collected as part of a promotion.] Onnit’s Alpha BRAIN is a supplement designed to purportedly enhance cognitive function. It comes with a free trial and money-back guarantee for first-time users. Users should consult with a registered dietitian or brain specialist before purchasing this product, though I found it to be a helpful aid for mental clarity, productivity and focus. Ingredients good for health , taste good , pakaging clean .
