Great mental booster

As someone who has used Alpha Brain for several years, it really is a help with my focus and creativity. Would recommend for anyone needing assistance with their concentration.

Definitely works as intended!

Honestly I was skeptical about purchasing this. But I’m glad I did and noticed results quickly. Everything just seemed very fluid and easier to grasp. Will continue to purchase from here on. Thanks

Not great.

After taking it made me feel dizzy and very uncomfortable. Took it three days to see if maybe it was just for the first time taking it but that feeling did not go away.

Alpha Brain rough on gut

This stuff was rough on my gut. Made me dizzy too. I don't have any food allergies or sensitivities so it was really surprising. Took a few days break and tried again not realizing the connection and it happened again.

I can talk!

Definitely helps me feel more alert and articulate. Can recall my vocabulary much more easily, which helps a lot at work when I am talking to groups of people.

Honest Review

I don't feel any different than when I was not using this product. I was hoping it would keep me focused and give me energy and help memory but I'm just not seeing it. Been on it for over a month now.

Made me sick

It made me sick. I took two and two hours later was fighting down nausea for seven hours. Unwell for two or three days. Only choosing "one week" of use because there's no option for one time only. Was refunded.

Unfortunate

I have noticed absolutely no difference. I would like to try more, but I ran out and it is too expensive to get more at this time. I follow Onnit and members and their journeys pretty closely, so this was very unexpected.

It works for me

So far I feel a huge difference in focus and memory. I'm quicker to snapping out of being lost in thought and I'm able to tackle multiple tasks at work without get flustered.

Read the whole review not just the stars.

Just didn't work for me. I got a weird brain that's why I'm looking at nootropics. It was like drinking a strong cup of coffee for me. I just need to hit different pathways. Don't let my review stop you from trying it though. Everyone is different.
