Hard Pass. Expected more from Onnit / Rogan

Mech. Can’t really tell any effects. Definitely not like all the commercials on social media. Was expecting just a little help but nothing. Won’t be buying again.

Alpha Brain is more important to me than coffee.

I've been an Alpha Brain user for over 3 years now. I have shot over 70 episodes of TV with Alpha Brain flowing through my body. I swear by its effect on my work.

Mehhhh... it's ok

This stuff is kinda hit and miss for me. Some days I take it and I get nothing. Other days I get so much energy I can't sit still or shut down for bed.

All day affect?

It definitely makes me feel better and more "with it" . Wish that would carry me through the day though. I take it in the morning. Definitely makes first things more coherent. Not sure if I should take it again in the afternoon though?

Clear headed

This is a purchase for my adult son. He has been using Alpha Brain and New Mood for almost two years. He says he feels happy and healthy and has a clear head when taking these supplements.

Clear mind, super focus

It really works. It doesn’t give you energy or anything like that. Just clears my mind and when I sit down to work, I’m all in. I’m able to focus and not get distracted. I’m obsessed.

Works well, the recommended dosage was a bit much.

This product is great! I ended up cutting the dosage in half bc it was a bit too much for me. I don’t metabolize so this is typical for me. I have felt more focused on projects and physically refreshed as I go through my day.

Alpha Brain

I have been taking this product for six months. I feel I have more mental clarity. I've been having a really productive year and I plan on continue taking this.

From a DPT

I definitely know if I haven’t taken it. It has helped me with studying for my Doctorate and I notice clarity when taking tests. answers come quicker and studying is easier to focus
