They’re good

[This review was collected as part of a promotion.] They helped me a little, I’ve been used for a couple of days and I feel more focus and proactive. Not a big change but I think it’s progressive. Not taste at all which I love. Very goos ingredients and looks good quality

Works great!

[This review was collected as part of a promotion.] Been taking Alpha Brain for a few weeks now and I’m loving the focus boost! Great for productivity without the jitters. I take one before work or content planning, it really helps me stay sharp. No aftertastes and no nausea after taking these capsules

My favorite supplements

[This review was collected as part of a promotion.] I really love any supplements made by Onnit. These supplements really help for those days you feel groggy. Helps me keeps focused on my tasks ahead of me. Doesn’t take bad either as it’s in a capsule. It is a little pricey but totally worth it!

Quality

[This review was collected as part of a promotion.] I took a long time to review this product because I really wanted to see how much of an impact it can have. It has quality ingredients from a brand that is widely recognized in my opinion and I could see myself buying this again.

They work

[This review was collected as part of a promotion.] The pills are pretty big and the serving size is 2 pills so I don’t know how often I will take them just because they are hard to swallow. I will say I believe these are effective as I noticed I was more focused after taking them. It did make my teeth feel weird/it felt like I was noticing my teeth more. If there are days I need to focus more or I am feeling tired I will probably take these but these are definitely not an everyday supplement for me. My husband came to the same conclusion I did about them. Not a love but not a hate either!

Effective

[This review was collected as part of a promotion.] I have been taking this supplement for 1 week now, and I have noticed that my focus and memory have improved a lot. I am more attentive to small details that I could not focus on well before. I have not experienced any side effects, which is great. I really like that the supplement does not have caffeine as an ingredient because I prefer to avoid stimulants. I would recommend it.

I liked the product...until it nearly killed me

Took it or a week and had incredibly good focus after taking the supplements. However something did not mesh well with my own body chemistry and suffered a mild heart attack. I stay away from caffeine and alcohol. I'm 48 years old an a ex professional fighter. I'm doing OK now but I suggest seeking a Dr's advice before embarking on any supplemental journey.

No noticeable difference

[This review was collected as part of a promotion.] I took two pills a day for about two weeks and didn't notice even a slight difference with my memory or overall focus. I'm not sure how long you are supposed to take them but I finished the bottle with no results.

Thanks for leaving a review about your experience with Alpha Brain! We’re bummed to hear that you didn’t have the experience that you were hoping for. While we typically suggest trying out for 2 weeks to feel effects, being that we all have different needs, it's expected that we all respond to supplements a bit differently, and we're glad you gave it a shot. -- Cailee B.

Onnit

[This review was collected as part of a promotion.] I love that it supports cognitive functions, including memory, mental speed, and focus. Which is super important. I would have to use longer to really see the results. But, so far it’s easy to swallow, and I’ve noticed I am more “in the zone” Will continue to take the rest of the bottle.
