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.

Great supplement

[This review was collected as part of a promotion.] What an amazing supplement that truly provides amazing results! I wanted to use it for a while before I left a review. I can honestly say that I feel like I’ve had more mental clarity. I felt better mentally and my focus has been so much better.! The cast is definitely reasonable and no bad taste! Definitely going to be trying more of these in the future!

Had a terrible reaction!

Took this product and a couple hours later I was so sick. Nausea, vomiting, diarrhea, dizzy, increased heart rate, the list goes on. I looked online to see if anyone had a similar reaction and negative side affects seem to be quite common with Alpha Brain. I will never take this supplement again.

I think this stuff really works

[This review was collected as part of a promotion.] I have a friend that has been taking this product for a while now and she has recommended it to me several times. I’m so glad to receive this product and will start taking it after I finish a current supplement. She has told me that it is extremely effective. It helps her focus as well as recall things that have been a challenge for her. She says that her mummy brain has been repaired with this supplement. Packaging is nice as well as it is affordable.

Pretty good

[This review was collected as part of a promotion.] This actually works. Whatever is in this really helps my busy brain focus. I might actually go get it from a store because it works. It looks and taste like regular supplements so no comments about that.

Capsule

[This review was collected as part of a promotion.] This came with 30 capsules. Packaging was easy to open. According to instruction , gotta take 2 capsules daily. So it will last 15 days. Ingredient looks good. Since it’s a capsule it is easy to take.

Nice product

[This review was collected as part of a promotion.] I liked this product. I am a mom of 2 under 2 and my mind has really been all over the place lately. I don’t know if it’s a coincidence or not but I have been able to remember things better because I had been so forgetful. I also liked how it didn’t stink, most supplements stink.

Worth a try

[This review was collected as part of a promotion.] I did see a difference after a few days. I felt sharper, more aware, more alert. I do believe with consistent use, this product can seriously help with brain function. The capsule didn’t have a bad taste; no taste at all. Definitely worth a try.

Not bad!

[This review was collected as part of a promotion.] I am super unfocused all the time and these were great! The have organic ingredients to help you focus. They definitely do but it also made my slightly nauseated too. I’m thinking you might need to eat a large meal before taking it.
