It works

I tried switching to another product and quickly noticed that it was not comparable. I have returned to using Alpha Brain daily.

A product that works.

After 3 weeks of taking "Alpha BRAIN" I notice more clear thinking and memory. I recommend this product to everyone I care about.

Get. This. Product.

Great product. Keeps me mentally sharp and focused. I 100% notice the difference on alpha brain vs not on alpha brain.

Placebo

Not much difference after taking it for 15 days, seems like a placebo that’s there to make you think it doing a lot if you believe in it

Thanks for giving Alpha Brain a shot and for sharing your experience! 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. That being said, if you still aren't feeling it after 2 weeks of regular use, let us know! We're happy to help with some supplement tips and/or to help facilitate a return if needed. You can email help@onnit.com for further assistance with your order!

Love and hate

I love e mental boost I get from alpha brain, but the shipping has been a painful process. My last order took 8 days to even ship.

Awesome product

Awesome product, you should get the 30 pack and see if you like it and then go to the 90 for cost savings.
