No side effects. Noticeable Results.

Excellent product! I got the free trial as I was skeptical given the mixed reviews. I did notice a big difference day after day of taking it. I have had no side effects. I even tried skipping random days to really get a good comparison and noticed tremendous improvements in my productivity and focus when taking alpha brain.

Headaches gone.

I used to get a lot of tension headaches, especially when my girlfriend talks nonstop to me and I just want a break sometimes. This definitely helped reduce it it seems. As for focus and memory, in still not sure though. I will have to keep using and see.

Alpha brain

I have noticed that I seem to be able to focus on a task more clearly than before taking alpha Brain. I'm actually only taking half the dose. So overall I can tell a difference. I've been taking it for about a week and a half. Would like to try some more onnit free trial products.

Not sure it’s worth the money…

Honestly me and my buddy both have not felt or seen any effects or improvements. We’ve both been taking it for several months with no improvements that we can tell. I know supps can affect different people differently so give it a test run yourself if you’re curious but we haven’t seen anything. Both M 40+.

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.
