Feel weird...

I haven't seen any other reviews about the pills making you feel weird. The 1st day I took 2 right after eating. A couple of hours later, I felt nauseous and light headed. It was so strange... I threw up a few times and that feeling was still in my gut. Didn't try again for a week. This morning I took 1 pill after a meal. I feel a little weird with an upset stomach. Nothing like the 1st time though. Thank goodness. Not sure if it's just my body rejecting these pills or what. I'm nervous to try another day. Maybe it'll get better? I can't handle it getting worse again. Anyone else feel this way?

👍👍

[This review was collected as part of a promotion.] By the first two weeks of using this, I could tell my focus and memory had improved. It was noticeable how much more I was retaining.the only thing I did notice when using this product is i felt a bit of tingling all over my face after a fever hours after taking it...but overall all is a good product...

Good for focus

[This review was collected as part of a promotion.] They were pretty good. There is no taste and no aftertaste. As far as focus, I would say they worked. The memory part my show after taking for a while, so I'm not doubting it. Would recommend. Had no side effects

Not my cup of tea

[This review was collected as part of a promotion.] The taste is okay , I personally don’t feel any different after taking this supplement. However most products recommend a continuous dose and over a period of time can feel the effects maybe that’s the case with this .

Focused, Alert, Amazing Dreams.

The title says it. This kicks me up to a higher level, maybe about 15-20% higher focus and alert. That with some green tea in the morning, I streamline through my day moving from one task to the next without hesitation. When its time for bed I know I'm in for an adventure. No lie, I seriously have action adventure movie type dreams where I'm trying to stop a bad guy even sometimes I'm being chased and constantly plotting my next move, just fun and sometimes weird. I haven't really noticed any change for me wit the new formula. I take 3 capsules in the morning and that's all I need. So I just want to say thanks for this product that for me has always worked in everyway that it is described.

Actually works!

[This review was collected as part of a promotion.] I’ve been using this for about a month now, and I’ve actually been noticing improvements in my focus and memory. Sometimes I feel a little groggy or have trouble remembering or even articulating things at work, but I’ve noticed since taking these supplements that I have a little more energy, my head is a little more clear, and I’m able to focus more. I’m hoping that with continued use, that I’ll see even greater improvements. I’ll definitely continue buying this because it’s priced fairly, the packaging is attractive, and above all, it works!

Meh, doesn’t beat a nap and Celsius energy drink

[This review was collected as part of a promotion.] Um, not sure what I am supposed to feel but mental clarity isn’t exactly it. Looking at the ingredients it is nothing harmful and caffeine free. Not really adding anything specific to my focus as well.

Thanks for leaving us a review about your experience with Alpha Brain! We’re bummed to hear that you didn’t have the experience that you expected while taking this product. We all respond to supplements differently, not only in how they affect us but how quickly they affect us. We definitely recommend taking the product at the recommended dose for a solid two weeks before deciding whether or not it’s working for you.

Great for focus

[This review was collected as part of a promotion.] These Onnit Alpha supplements are a good way to avoid caffeine and give yourself a boost for focus. It has Vitamin B6 and a blend of herbs (oat straw, bacopa leaves among others) that nurture your brain. So far it's been helping me with having that clarity through the day - the difference isn't night and day for me personally but I can see how this can help someone trying to find other ways besides caffeine to get things done and have some focus. The pills are standard sized and easy to swallow. Overall it's one supplement I would recommend to give a try! Thanks for sending me samples Influenster and Onnit.

Great for focus! Caffeine free

[This review was collected as part of a promotion.] “Your day is about to get a lot more focused.” Alpha brain has nutrients to help support cognitive function. I started pre-nursing school last week and I have been using this. It works great! It helps promote blood flow, aids in mental clarity, and is made of nootropics. This is a caffeine free formula and is very effective! I highly recommend this if you have trouble focusing!

Cognitive Support

[This review was collected as part of a promotion.] I started taking Onnit Alpha Brain daily supplements about a week ago. The idea of improving my memory and focus was beyond intriguing - and maybe too hopeful. It may just be me, but I didn't notice a dramatic difference. I received this product compliments of Influenster in exchange for my honest review. I will continue to take them until I finish the bottle. I want to be thorough in trying to support my memory and focus.
