Great product

[This review was collected as part of a promotion.] I recently received Onnit Alpha Brain Memory and Focus and I am very happy with it. It is long lasting and it doesn't leave any bad aftertaste or give you an upset stomach. I also like that it is gluten free and caffeine free. I would definitely recommend this product.

More focused

[This review was collected as part of a promotion.] I’ve had a noticeable improvement in overall how I think and feel, with these, I feel more focused, my mind feels more clear, and overall, I feel more sharp. The price is up there, but I think it’s worth it. It took a good few weeks for them to fully take effect, but they’re easy to take, and work well!

Not worth the price

When I first started using alpha brain I did feel like I noticed an increase in focus and short term memory but after a few weeks i noticed no difference in days i took it vs days i dont and after a few days of non use felt like i had harder times focusing than i did before i started using the product. Could all be placebo could work but my body builds a tolerance. Not sure but I have canceled my monthly subscription because to me it dosnt seem worth it. Just my opinion

Hi Pat, Thanks for your feedback! Sorry to hear about your experience with Alpha Brain. Sometimes the body needs a break from supplementation. In theses cases, we recommend taking a week off to let your body reset. After a full seven days without Alpha Brain, try taking it again to see if that helps! Again, thanks for your feedback and #StayOnnit!

Ok

[This review was collected as part of a promotion.] I didn't really notice any effects from this product. That being said, with any supplement, you really need to take it for 90 days to get the full effect. It's seems to have quality ingredients. Packaged well, and has no smell or taste.

After two weeks,its giving *nothing*

[This review was collected as part of a promotion.] I’ve been taking this for a few weeks now and haven’t felt much of a difference in my mental performance. The taste isn’t horrible though and the smell isn’t too strong. I’ll probably finish the bottle and see if there is any compounds effects for using this product.

Will buy it again

[This review was collected as part of a promotion.] The package is nice. However, the lid is a little hard to tighten. I was afraid at first because I don’t know if it will have side affect. Luckily that this doesn’t give me any nausa or anything. I’m not sure that it will help me focus, but I think It would.

Seems good so far

[This review was collected as part of a promotion.] I recieved this complimentary from influenster in exchange for an honest review!! I not secure this has helped or not. But I did feel a bit more focused after taking them a couple days!! You get alot in the bottle, and even though the pills are big they're easy to swallow!!

Focus in a jar

[This review was collected as part of a promotion.] This is a wonderful caffeine free option to assist with better focus while I work. It does not have a taste and the pills go down easy. I used them for about 3 weeks so far and can notice an increase in productivity which I'm sure my job is excited about. Def worth a try if you're like me and you go in 20 directions each day!

Helps me get thru my day

[This review was collected as part of a promotion.] The Alpha Brain supplements from @onnit are just what I need at this stage in my life. I have so much going on between my kids, extracurricular activities and my full time job, that it can be hard to focus and get thru my tasks. Alpha Brain offers support for focus, memory and reaction time. These capsules are of average size and easy to take with my breakfast.

Sharp Focus, Rough Nights

[This review was collected as part of a promotion.] Tried Onnit Alpha Brain and was excited for a focus boost and it definitely delivered on that front. But, the downsides? Big ones for me. The "comedown" was rough—felt nauseous and it seriously messed with my sleep, waking me up every hour. Loved the focus, not the side effects.
