Nothing

I noticed no difference good or bad, I've been incorporating it into my daily routine. Sorry, you asked for it. It's it possible they just don't work for me? If course. They just might not be supplements I need.

I think It is a good product so far

Sometimes I feel like I am on top of the world and others I don’t feel much of a difference. Not sure what to attribute it to. I think I’m going to continue using it though for now

Thanks for giving Alpha Brain a shot and for sharing how it's going so far. Everyone's experience can be a bit different with a formula like this. It's formulated to help support memory, focus, and processing speed, and it can take some regular use to really feel these changes. We're happy to help with some supplement tips and/or to help facilitate a return if needed. You can email help@onnit.com if you need further assistance with your order!

It works, but I’ve had better cognitive supplement

First couple of days using this product, I could really tell that it was giving me a mental boost. Not sure if it’s a tolerance issue, but after about the 6 or 7th day the effects seemed to subside. I would purchase again if the price was lower.

Great product but didn’t work for me.

Started great but my body didn’t like something in the formula and I had the jitters. Grateful for the sample to know upfront if this was a product I could take long term. Sad I didn’t work for me.

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.

Gastric distress

I have been taking I capsule /day and while experiencing a little more clarity I have also been having gastric distress and expelling gas night and day. Can you speak to an ingredient in the Alpha Brain memory&focus that might be the problem?

I bought this 4 weeks ago and haven't noticed anything different. Maybe I was expecting too much but the reviews made it sound like they are the best thing since sunshine. They may be helping but I'm not sure. The reviews are Hiped up.

Meh

Not a huge difference in cognitive clarity. My focus was not improved after 2 weeks of constantly taking Alpha Brain. I felt the same effect from taking an L-Theanine supplement as I did with this, at 1/3 the cost.

Thanks for reaching out and leaving a review! Apologies that Alpha Brain did not work for you. Everyone reacts differently to supplementation, and it's not uncommon to have different experiences. Please note that this supplement's main focus is to help support memory, focus, and processing speed - sometimes it can take a few tries to notice these effects. That being said, if you are ever dissatisfied with your order, you can always contact our customer experience team for further assistance!

I felt nothing

I felt nothing. It did not help me focus, give me energy or anything in between. I figure it just doesn't work on me. Might work for others but not me
