It does work!!!!

This stuff really works. I could feel a difference within about 3 days. The cleaner your system is (no booze, cigs, garbage food) the better it will work. give it a try....

Didn’t work for me or hubby

Husband and I took the supplement for two months and both saw nothing different energy, wise or focus. For myself the only thing I noticed that changed was that I had a harder time going to sleep and staying asleep. Also, I sweat a lot more.

Maybe worked?

[This review was collected as part of a promotion.] Honestly didn’t notice much difference using this product, even using the full container. The smell isn’t awful but not super pleasant when taking.

We appreciate your feedback after trying our Alpha Brain, although so sorry it wasn't a great fit for you! Because everyone reacts differently to supplementation 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 - and sometimes it can take time to notice these effects. Regardless, glad you tried it out!

The results were almost instant!

I’m very happy with the results. I feel like my brain function is back to my early twenties, and I just turned forty. I’m excited to check out your other products as I build off of this momentum.

I started taking alpha brain 2 weeks ago and have thus far not felt any noticeable effects. I will finish out my purchase in the hopes I feel something.

Onnit Alpha Brain

This stuff is awesome! One of the best brain formulas I have ever tried. We are featuring it on an endcap in June and I can't wait to get the other kinds of Alpha Brain and try them. Truly an amazing formula. It kicks in right away, too.

Work your brain

The product works, but you have be proactive. While taking the product, I have decided to learn rap lyrics and remember them. I remember them faster and I also work my brain to remember numbers that I encounter at work.

Alpha Brain

I absolutely love it. I can definitely tell a difference in mood and motivation. I'm 55 and in menopause and this has helped with memory, mood, and procrastination.

Not sure its helping other than giving money away.

Perhaps in not taking it right but I'm not feeling a benefit, I'm still finding it hard to be motivated anymore than i previously was. Let me know if you have any advice PLEASE!

Thanks for taking the time to share your experience so far! Being that we're all unique individuals, it's expected that we have a range of responses, since supplementation is not one size fits all. Sometimes it can take a few tries to notice these effects. Experimentation is key! Please note that this product is meant to help support memory, focus, and processing speed. 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!
