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.

Doesn't seem to do much

Alpha Brain did not appear to have much if any of the effects that they claim. I dont know if it takes longer to get into your system or what, but it does not do much in my opinion as of yet.

Thanks for leaving us a review about Alpha Brain! We all respond to supplements differently, not only in how they affect us but how quickly they affect us. We definitely recommend taking the product at the recommended dose for a solid two weeks before deciding whether or not it’s working out. After that time, if you’re still not feeling it, please feel free to reach out to us directly for further assistance.

The “FOG” has lifted!

I do not feel like I am in a fog and am able to remember “the little things” without having to make a list anymore or remember where I put that list after I made it!

Alpha Brain

This product is unbelievable, my wife had an immediate change for the better. Her low moods lifted and is a changed woman, much more happy and loving. I am super motivated at work with bundles of energy. I wish I found this product earlier in life.

Great product!🌟

Just a great product. Has many benefits. The best benefit of using this product is ur ability to pull information out of your brain. Also helps with retaining information.

Need More Time?

I was intrigued to try it out, but admittedly didn't notice any sort of difference/improvement from this product. Perhaps it's one of those that needs more time to take effect?

Thanks for leaving a review! We're bummed to hear that Alpha Brain has not worked for you so far. Please note that this supplement's main focus is to help support memory, focus, and processing speed, and it can take some regular use to really feel these changes. We definitely recommend taking the product at the recommended dose for a solid two weeks before deciding whether or not it’s working for you. That being said, if you are ever dissatisfied with your order, you can always email our customer experience team at help@onnit.com for further assistance!

Alpha Brain for a more alert brain!

Alpha Brain has been impactful for me; clear mind, improved recall and greater alertness. Chronologically, being on the more "mature" side, perhaps the positive effect is more pronounced.

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.

Refund request.

I have been meaning to apply for a refund. I haven’t felt any benefit from this product, and would be ok with receiving store credit. The majority of pills are still left. I can return it.

Hi Fraser! Sorry to hear if you didn't experience the results you expected with Alpha Brain! If you just took the product a couple times and noticed some difference, it may be beneficial to try for at least a solid two weeks before you decide whether or not it's working! For some people, they can tell a change after the first dose, but many others needs a little bit more time to see a difference! If you need further assistance please reach out to us directly.

Improvement with just 1 pill and soon 2 a day.

I felt like this product helped with my cognitive thinking and I will continue to try it taking only 1 pill to start. I will make change over to 2 pills soon and see how it effects my thinking and energy levels. Love it so far. Thanks
