Onnit ALPHA BRAIN® – No Noticeable Effects

[This review was collected as part of a promotion.] I received these products for free from Influenster and brand(s) in exchange for my honest review. I wanted to like ALPHA BRAIN®—the ingredient list is impressive, with well-known nootropics like bacopa, cat’s claw, and Alpha-GPC. However, after taking it consistently for a few weeks, I didn’t notice any real difference in focus, memory, or mental clarity. No side effects, but also no noticeable benefits. It may work for others, but for me, it felt like a well-formulated supplement without the promised results.

Maybe truly intended for males only

[This review was collected as part of a promotion.] Ok I understand that this brand is mostly target audience for males however I still tried the product. It wasn’t my fave. The supplements made me feel dizzy and in a way foggy minded (maybe this supplement is only meant for males?!) I took one supplement a day and still didn’t like it. It’s intended for two supplements a day but I couldn’t bring myself to do so. I was very excited to try but disappointed

Ok

[This review was collected as part of a promotion.] I like the idea of this pill. And I know that its effects are kinda unproven. But I was really hoping it would. And it didn't. I didn't notice any improvements. But I also didn't notice any worsening.

Definitely worth it.

[This review was collected as part of a promotion.] Alpha Brain has genuinely exceeded my expectations, delivering a remarkable boost in my cognitive function! From the moment I started taking it, I've noticed a significant improvement in my focus and mental clarity, making complex tasks feel more manageable and less daunting. This supplement has become an indispensable part of my daily routine, helping me to stay sharp and on top of my game. I'm particularly impressed by the sustained energy and heightened concentration Alpha Brain provides without any jitters or crashes, which is a common issue with other supplements. It truly feels like my brain is firing on all cylinders, allowing me to tackle creative projects and analytical challenges with renewed vigor and efficiency. The natural ingredients provide a sense of reassurance, knowing I'm supporting my brain health in a positive way. In conclusion, I wholeheartedly recommend Alpha Brain to anyone looking to enhance their cognitive performance and unlock their full mental potential. It's a game-changer that has positively impacted my productivity and overall mental well-being. This supplement is an absolute must-try for students, professionals, or anyone seeking to elevate their cognitive abilities—you won't be disappointed!

I forgot to take it regularly

[This review was collected as part of a promotion.] Not sure the value of this is worth it. The bottle i received had 15 days' (30 capsules) worth of "treatement" . Funny thing is I've forgotten to take it many days so I'm probably not getting the benefits.

Thanks for giving Alpha Brain a shot and for sharing your experience! Everyone's experience can be a bit different with a formula like this. It's formulated to help support memory, focus, and processing speed, and it can take some regular use to really feel these changes. We suggest trying it for at least two weeks and if you still aren’t happy we can help with some supplement tips if you email help@onnit.com for further assistance with your order! -- Cailee B.

Really expensive

[This review was collected as part of a promotion.] For the price, you only get 15 days worth (2 capsules daily, 30 total) which is pretty expensive in my opinion. I like the ingredients, though. I can’t tell if it’s a placebo or not, probably works best if I take them for more than 15 consecutive days, but I can’t afford to keep buying them.

Thanks for taking the time to share your experience! We're sorry to hear that Alpha Brain wasn't the right fit for you. 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! That being said, we would never want you to feel stuck with a product that didn't meet your expectations, and if you reach out to our Customer Service team, they'd be happy to help further!

Help me stay super focused

[This review was collected as part of a promotion.] This Alpha BRAIN supplement from Onnit is just magnificent. Ever since i started taking this my reaction time has been quicker, i’ve been way more focused, and my memory has been improving. They come in a nice little bottle, containing 30 capsules, at least for the size I got. They have no taste, which is perfect, and they work fast. I noticed effects not long after taking them. You need to try these if you haven’t already!
