Great for clearing your mind

[This review was collected as part of a promotion.] I’ve been really liking this supplement. As someone who works from home a lot and has a job that requires a lot of mental capacity, this product has been life changing. It definitely has made me think clearly, even when I’m overwhelmed or if I’m having a long day. I have to say make sure you accompany this with a healthy meal. I did take this after having fast food and it did upset my stomach a bit. It’s a simple capsule so this product doesn’t really taste like anything and it’s easy to digest.

Get on it

[This review was collected as part of a promotion.] What a great natural alternative to chemicals. I am staying focused without harsh chemicals being put into my body. This is the first time using natural mushroom as a way to manage staying on track. A great value and simple packaging.

Waiting for results

[This review was collected as part of a promotion.] I haven’t really seen any changes yet, so this is why I reviewed this way. I do like that you get a lot in the bottle, and that it’s made with trustworthy ingredients! I just didn’t see a change for myself. I am continuing with them to see if anything happens. I do think the packaging is nice, and the taste is not bad

Thanks for reaching out and leaving a review! So sorry to hear that Alpha Brain did not work 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 - sometimes it can take time to notice these effects. That being said, if you are ever dissatisfied with your order, you can always contact our Customer Service team for further assistance!

Support your brain health

[This review was collected as part of a promotion.] Alpha Brain daily cognitive support supplement helps support my memory, focus and reaction time. It definitely has helped me focus while I'm at work a lot better. The capsules are not too big and easy to swallow.

Boost for the brain?

[This review was collected as part of a promotion.] This supplement made up of herbs, vitamins, and amino acids claims to enhance cognitive function improving your memory, focus, productivity and clarity. With products like this it’s always advisable to consult with your doctor especially when you have pre-existing conditions. There is no caffeine and it’s gluten free. The capsules are easy to swallow. I sometimes have difficulty focusing and this product did help me to be more alert and concentrate better after only a couple uses. Following the recommended dosage, I experienced nausea with a slight headache. I found taking 1 every other day works best for me. The cost for a month’s supply is pretty steep but will last longer by cutting the dose in half. I don’t know if I would purchase regularly because I’m not sure it’s 100% safe.

Not for me too much pseudoscience

[This review was collected as part of a promotion.] Definitely, not something. I am willing to try again when I first looked at the ingredients. I was kind of concerned. There's no studies that show this is actually effective, and it is not something that I would really chance.I tried it once and it gave me heartburn.

Focus has increased but no noticable change in mem

[This review was collected as part of a promotion.] Didn't have an after tastes like some supplements.. but I didn't notice much of a difference with my mommy memory... 🤦 Focus was definitely better but I was really hoping for the memory to improve... I'm only about 2 weeks in on using the product so maybe it will get better with time using it... But so far other supplements for memory that I've tried have had the same results... Not sure yet that I will grab another bottle for the memory part anyways..

Helps keep focus and concentration

[This review was collected as part of a promotion.] These supplements work well for me and help with my executive function and focus. They aren't too big so taking them isn't a hassle. Though, if you do struggle with pill taking I'd keep that in mind.

More focus

[This review was collected as part of a promotion.] I began taking the Onnit Alpha Brain supplement a couple of weeks ago and quickly noticed a difference with my brain processing. I have quite a bit of trouble focusing on one task at a time and noticed an immediate difference when completing a work project. I will keep taking this product!

Could be worth a try!

[This review was collected as part of a promotion.] This product was fine! I don’t notice much of a difference after taking it. That’s not to say it wouldn’t work for other people. I enjoy the branding and packaging. Taste isn’t notably bad for what it is either.
