Amazing 100%

[This review was collected as part of a promotion.] Highly recommend Alpha Brain, definitely clears my fog. To the people who have experienced nausea, I did experience nausea for the first 2 days of taking AB, but I persisted and gave it one more go. On the third day it was like a switch was flicked, my focus arrived and the fog disappeared. Honestly, I recommend to push through the nausea - it goes away after a couple of days, presumably when your stomach adjusts, then it's smooth sailing & life changing. Cheers Onnit.

Waiting

[This review was collected as part of a promotion.] Alpha brain is easy to take. I’m not too sure if it’s working completely. I’m hoping I will know in another month or two after I buy another bottle. It seems like it has decently good ingredients, so hopefully it does help me feel more focused after a while.

Thanks for giving Alpha Brain a shot! 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 to get a good sense if it's a good fit for you or not!

It works but it makes you sick

This is my third bottle of alpha brain now and I love the benefits of it. My only issue is that while it helps with my mental clarity it makes me incredibly nauseous and I have thrown up a few times due to the pills. I feel the coating on the pills is part of the issue. I would recommend this to anyone who has a stronger stomach than I do because I really believe in the product.

We appreciate you taking the time to leave us this review! We're happy to hear that you're experiencing mental clarity while taking Alpha Brain! But, we're sorry to hear that you're experiencing nausea as well! To potentially alleviate this effect, you may consider taking just 1 capsule at a time and be sure that you're taking the product with food. The capsule itself is a standard vegetarian capsule, so unless there is a sensitivity there, this should not be the issue. Please feel free to contact our Customer Experience Team if you have any questions! You can reach us at 855-666-4899 or by email at help@onnit.com. Thank you!

Great energy boost!

[This review was collected as part of a promotion.] The bottle comes with 30 capsules. The serving size is 2 a day. So this lasted about 2 weeks. I did not notice a difference in my ability to concentrate. I did feel less tired throughout the day with work and school. I took it daily at 9 am with food. I got nauseated every afternoon around 2-4pm. (Not sure why, but it ended when I stopped taking the pills.)

Good for concentration

[This review was collected as part of a promotion.] I was hesitant to try this product after reading several reviews with negative reactions. I am a busy mom and don’t eat until midday so I waited to take the pills until then. I did notice a difference in my ability to focus but I can’t really tell the difference with memory. I plan to keep taking them to see if there is any additional improvement.

ONNIT ALPHA BRAIN

[This review was collected as part of a promotion.] I received this product free in exchange for my honest review. I was excited to try this product to help with memory and focusing. However, after using it for a few days, i started to get nausea and bad headaches, so I stopped using the product

Husband approved

[This review was collected as part of a promotion.] The only reason I am giving this product only 4 stars is simply because I haven’t had a long enough time to give an honest review if they have a long lasting or long term effect. They seem to be working well for my husband. He says they aren’t bad tasting and the packaging is super easy to read and very manly looking lol

Pricybit helpful

[This review was collected as part of a promotion.] value seems a little pricey. pill is a little big, not bad. The taste is great. i will say memory has improved beyond what a typical multi vitamin can provide. overall i would consider the product if it were a bit cheaper. Good packaging.

Worth Trying

[This review was collected as part of a promotion.] I recently tried this Onnit Alpha Brain Nootropic Brain Health Supplement - 30ct bottle. The packaging and bottle are nicely sealed to keep the supplement fresh. The capsules have no taste or scent and are easy to swallow. As far as effectiveness goes--they are definitely worth giving a try. I've read up on them and seen various results and outcomes. I didn't notice any negative impacts or side effects. I generally am a high stressed person with a high stress job and difficulty focusing. I've been taking them daily before work for a couple of weeks and do seem to notice slightly less stress and edge during my workday. I also seem more focused during the day. I didn't notice any change in memory.
