Great product

[This review was collected as part of a promotion.] I am obsessed with all things health related especially my brain so I was excited to try this. I have been taking as directed for the last few weeks and I feel more focused. My memory seems better too! The pills don’t have any kind of after taste. I do try to eat healthy and I wouldn’t try to use these as any substitute for eating right but I would recommend trying these if you feel foggy and unfocused.

It worked but gave me acid reflux

I had done a 1 week trial with no issues, so I bought a 90 pill bottle. After about 2 weeks I started noticing that I was having trouble swallowing and was having terrible acid reflux. Stopped taking the pills for 2 weeks and acid reflux was gone, so I tried taking the powder out of the capsules, to see if the capsule was the cause. 3 days in and started having difficulty swallowing again so had to stop. Going to try the instant now. When I was taking, it worked great, but cant take it in the pill form.

Alpha BRAIN

[This review was collected as part of a promotion.] My mom used this product before I tried it. It worked great for her in supporting her memory and mental clarity. The cognitive support ingredients with L-Theanine, Vitamin B6, Alpha GPC and Phosphatidylserine help build an environment where the brain can function in all its cycles, supporting mental clarity. Use Alpha Brain to help you focus better and be more productive

It works

[This review was collected as part of a promotion.] I have been using alpha brain by enjoy now for 2 years. At first I didn’t think it worked. So I stopped taking it. In a few days I noticed I was having a harder time recalling things . Got back on it and sure enough, there was a change. I highly recommend. It is a little on expensive side. Worth it to me . I take every morning

Like it alot.

I've been taking this product for a little over a month and I am enjoying the benefits. I work as an EMT full time, and the I can tell a difference in my reaction time, and how quickly I can wake up from a deep sleep. I took a star away because of the price, at about a dollar a pill it would have to be the first supplement I drop if money were to get tighter.

So far so good

[This review was collected as part of a promotion.] I tried Alpha Brain to help with focus and mental clarity. I liked that it doesn’t have caffeine, so I didn’t feel jittery. It helped me stay more focused during work and gave me a clearer head. I did notice some mild side effects like a slight headache the first couple of days, but it went away. The capsules are easy to take, but it’s a bit pricey compared to other supplements and doesn’t taste weird. It does work for short terms of focus since I have not been taking them too long!

Not for me

[This review was collected as part of a promotion.] I unfortunately can’t give a review as to how this supplement worked as it made me incredibly ill. I made sure to take it with food as stated on the bottle. I ended up throwing up multiple times and laid out on my couch for the whole day.

Immediate results!!!

From the first time I took this supplement I noticed an immediate reaction. I took them a few hours before bed time and during my dream cycle I was immersed in an ocean of rapid dreams! It was like watching a hundred movies all at once! Once I awoke I felt fully rested but a little dazed. With in the next 15 days, in which I've been taking them in the mornings, I've had increased focus and I feel much more clear! I look forward to the rest of the month and beyond. You owe it to yourself to try this supplement!
