Much More Focused

[This review was collected as part of a promotion.] I am pleased with these vitamins. I was able to tell a difference in how much more I was focusing on my tasks during work, since I noticed I was much more productive. They do not have a taste and can be taken after eating a meal. The packaging is a good size and enough comes in the bottle.

Amazing stuff.

I bought the Memory & Focus product over a year ago and really noticed a difference. I'm now 68 and before taking this, I was having trouble even with short term memory - something my mother had for a while before she passed away (at 94). I have another natural memory product from one of my doctors but it doesn't help with focus. Recently I stopped taking Alpha Brain when I ran out and thought I would see if I really needed it. YES I DO! What a difference. Back on the stuff again and feeling like "I'm Baaaaack!" and ready to live a fuller life.

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!

Didn't really feel anything

I didn't notice a difference when taking Alpha Brain. I even took 3 one time and didn't notice anything really. It may have provided a benefit in that I did really well on my exams while on Alpha Brain, but to be honest I'm unsure if the Alpha Brain actually helped as I studied pretty hard and prepared. My body is odd though because I've taken painkillers in the past and not felt anything.

Promising nootropic

[This review was collected as part of a promotion.] It seems like a promising nootropic! I like that it could affect acetylcholine positively but there is not enough info whether the amount included is healthy or a little negligent. But with nootropics, the efficacy wears off so overall, it seems like a good blend but it would be nice to see studies support the efficacy of this product.

Not for me

[This review was collected as part of a promotion.] I can't say this was particularly effective for me. Everyone is different and for me, it made me feel sick. The ingredients seem good and there was no weird taste. A decent value and the packaging was good. But I couldn't take it past the first day due to feeling sick.

Not for sensative stomachs

[This review was collected as part of a promotion.] I'm sure it's not the product itself and is just me but this upset my stomach pretty bad. I tried it with food in the morning and at night and also with just water. It still tore my stomach apart. There is no taste to this product that would be offputting. I read through the ingredients and nothing in it would push me to think anyone would have an issue. I'm sure the product is great and many people would benefit from it. I just unfortunately couldn't get past the stomach issue.

Focus, memory and reaction time

[This review was collected as part of a promotion.] Influenster and Onnit sent me this product for free in exchange for my honest opinion. Alpha Brain Daily Cognitive Support. Take two dietary supplements daily to help support focus, memory and reaction time.

They are Ok

[This review was collected as part of a promotion.] These did nothing for me. Literally. But for my sister who is one year older than I am (in her 30s) she said that she thinks these helped her be productive. She didn’t experience any side effects or any boost of energy. The capsules are easy to digest. The only con of this is that they can easily be mistaken for another supplement so you have to be careful with that.
