No change

[This review was collected as part of a promotion.] I received this product for free in exchange for my honest review. This supplement is suppose to improve your memory and focus but I didn’t find any change after trying it for 3 weeks. I’m not sure if I wasn’t on it for long enough or if it simply doesn’t work.

Thinking it may work better if taken longer

[This review was collected as part of a promotion.] I received these vitamins complimentary from Alpha and Influenster in exchange for my honest review. I can't say I noticed too much of a difference taking these for one month but I suppose I did notice a little more focus. I honestly just didn't notice too much of a difference personally and they are on the pricier side so I wouldn't repurchase.

I focused really well

[This review was collected as part of a promotion.] I really liked this supplement formula, it’s only 15 servings in there but I do think I was much for focused while taking these, I felt like I was able to achieve more of my chores without getting distracted as easily

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.

Didn't Work For Me

[This review was collected as part of a promotion.] I tried using this about 10 (ten) days ago. I have always struggled with focus and concentration. I also have difficulty with my memory at times. I was very excited to try this product. Unfortunately I did not notice any change or difference in my focus, concentration or memory. I did not notice any cognitive changes. This product did not work for me.

Super Effective

I used both the capsules and the powder in the packets alternating both ever other day and found out that each day I did take it I could focus andrember little details but that it was nothing like caffeine at all. On the days I didn't take it I fell back into my routine of being distracted and unorganized. So for. This product was very effective . So I bought more of it and each time I take it it remained effective

Will purchase again

[This review was collected as part of a promotion.] Using it every day! Great product that’s helped me more so than any other supplement. Not like this one thing solves everything but it’s a good boost for mental focus and energy. Not a big after taste either.

Memory and Focus

[This review was collected as part of a promotion.] I received this product from Influenster and Onnit for free in exchange for my honest review and opinion of the product. Hoping this will help with my memory. I've gotten to the stage in my life where I forget what I'm wanting to say mid sentence and why I got up to go in the other room. It's too early to tell yet, I'll keep you updated!
