Nice brain boost

[This review was collected as part of a promotion.] As a 36 year old mom of two with a full time job I’m always feeling fuzzy in the brain. This supplement is just what I needed to give me a little extra umph to my day. I has no caffeine so no jitters, it has all natural ingredients to help my brain wake up. The bottles comes with a month supply.

When doubt turns to confidence!

I bought it thinking, well, what the heck, it can't hurt. I wasn't too sure about the first few days I used it. I was feeling good anyway but today, third day trying, it made a difference. I am in customer service and I have to be alert and articulate or the clients will eat me alive. LOL. I don't feel jittery and I am jazzed to keep taking calls, helping clients and am planning on cleaning out my fridge after work too. What? LOL

Helped me get through the day!

[This review was collected as part of a promotion.] I was excited to try the Onnit Alpha Brain supplement, because I really needed it. My mom brain is getting worse every year. It's packed with Vitamin B, which helps tremendously. 2 capsules a day and you're set. Great product, you gotta give it a try!!!

Gave me head rushes and upset stomach…

[This review was collected as part of a promotion.] This product I did not like. It caused extreme head rushes and it caused me to feel ill. The packaging was intriguing with the colors but overall I would not buy again. It didn’t have an aftertaste like some supplements I’ve tried which is nice. Price point was affordable.

Not effective

[This review was collected as part of a promotion.] This product had no effect on me, I didn’t notice an improvement in my memory or focus whatsoever. Maybe because I didn’t take it long enough or it just wasn’t effective in general. The pills were also a little big and uncomfortable to swallow but they had no bad taste or smell. If i had a bigger bottle sent maybe i would’ve felt the effects by now

Liking so far

[This review was collected as part of a promotion.] Love trying new vitamins love that these didn’t have a bad taste and they weren’t hard to swallow. These I have found have helped me think more quickly and stay focused on the task at hand. I plan to continue use and reap the benefits.

Very beneficial

[This review was collected as part of a promotion.] I have lots of stress in my life and I am constantly forgetting to do things. I have tried a lot of options and this supplement works. It takes time, but I felt better and remembered more than before I used it I can tell a difference in my thought processes. I am able to remember better. Meets all my expectations, plus a great value in comparison to other brands. I've been using them daily. The taste is very light. Nice packaging. Recommend highly.

Helps with focus!

[This review was collected as part of a promotion.] I don’t have the greatest memory and tend to forget things often. I needed something to help with that as well as my focus. I think these supplements do help with focus but I didn’t really see an improvement in my memory so overall. These don’t have a bad taste and are easy to swallow in my opinion. I think these are worth trying out!

Brain Gain!

[This review was collected as part of a promotion.] Get Onnit for memory and focus. I have been playing cognitive games this month as a focus on improving my brain health. Therefore, adding Onnit to my journey this month has definitely boosted my progress. Therefore bottle is easy to open without a strong taste. For the progress and improvement Onnit is worth it.

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 .
