Absolutely the best product I’ve purchased online!

I get duped into buying a lot of products online and most don’t work. This one actually does exactly what it says. The older I get the worse my sleep is but I know that Alpha Brain is there to help me get through the morning. I recommend this to anyone who wants a boost mentally and physically!

Not for me

My experience with taking AB was not good. I took 2 with food the first day and did not notice anything different in my energy level, cognitive abilities or mood. A few days later I took 4 AB and was sick for most of the day. An hour after taking it I threw up 4x over the next 2 hours. I had to lie down because I felt horrible. Not caffeinated shaky horrible but the same uneasiness. I guess AB is not for me. I wish it was but it's not so I'll just stick to coffee!

Truly helped strengthen my memory

I’ve been using Alpha Brain daily since i received my 30 pack supply. I haven’t been able to notice to much difference in my focus as i still find my mind all over the place when it comes to work and school. I want to try the 60 pack supply so i can dedicate a month to researching my own focus and memory capabilities. I’m a big fan of onnit and Joe Rogan. I want to believe this product is capable of amazing things i just believe the 30 pack supply isn’t enough to truly notice a difference in function.

Use it everyday

I use Alpha Brain everyday for a clear mind and also helps me rest at night. I take two evry night before I go to bed and wake up with a rested and clear mind. I can tell a huge difference if I do not take it so I make sure I always have plenty on hand.

No break would be better

I really enjoy using this product! My only disappointment is that there was such a pause between when I ran out of the trial and when I received the new bottle I paid for. I think it would have been better, for me at least, if there wasn’t a break between when I ran out of the trial and began using the paid for capsules. Otherwise, this product has really improved my ability to engage with people and quality of life! I highly recommend it!

It works..............Well!

I was skeptical that a product could really make me feel 'sharper', but Alpha Brian does that, especially when paired with New Mood at night. I was up with no foggy feeling and stay sharp all day long even if I am a littler tired. Although the product is quite expensive I am prioritizing how good I feel when taking Alpha Brain and got on a subscription plan for both Alpha and New mood.

Alpha Brain #1

It works

At first I never noticed the difference when I took this versus when I had not. This last weekend after a physically strenuous day and little sleep I took the daily dose and notice an almost immediate difference. I think this product works it is subtle enough though where you don't "feel" different, like you would if you took a high dose of caffeine.

Definitely provides a mental boost.

Tried this due to negative physical effects (heart racing)and zero mental effects of caffeine. Alpha Brain seems to provide a good mental boost with almost zero physical effects. I take only one pill before work. Possible it contributes to a very mild headache and I have some trouble falling alseep the day I take it. It's like my brain doesn't turn off.
