Must try!

[This review was collected as part of a promotion.] I’m usually skeptical about things like this, but I will say that they are very effective from day one! You stay completely focused and on task, with what you wanna get done! They don’t have a weird taste to them and you are definitely getting your moneys worth!

Great for working from home cognitive support.

[This review was collected as part of a promotion.] It’s a good product. I need memory and focus support for my job or else I feel very groggy and out of it and unable to complete tasks. This helps optimize memory and reaction time. It’s a vegetarian capsule and it’s easy to swallow. Doesn’t taste like anything and there doesn’t seem to be much of an aftertaste. Huge amount of vitamin B6 and other interesting/unique extracts.

Extreme focus!

[This review was collected as part of a promotion.] This supplement is good when you do need a day to focus! The only side effect I did have was a minor headache but my husband did get a headache and a little nausea. He did notice he was more focus at work! Just eat before taking and be aware of the potential side effects!

Great!

[This review was collected as part of a promotion.] So I’ve taken two capsules daily for a week so far and I already feel that it has made a difference in me focusing more! I am definitely interested to see if this continues to improve but so far I have no complaints!

Great product for all its promising potentials.

[This review was collected as part of a promotion.] Onnit Alpha BRAIN capsules are magical. I was quite surprised at how quickly and efficiently they started to work. I have noticed I am now able to focus much better and remember things with a great detail than before. It has also improved my reaction time. Not to mention, the packaging was certainly pleasing to eyes.

Good!

[This review was collected as part of a promotion.] I was a little skeptical at first, but Alpha Brain really surprised me. I don’t feel wired or overstimulated. I was just clear-headed and focused. It’s subtle, but I notice I’m quicker with recall and stay more locked in during meetings or deep work. It’s become my go-to on days when I need to be mentally sharp without relying on caffeine. Definitely worth trying if you’re looking for a natural boost in brain function.

Improve focus and memory...

[This review was collected as part of a promotion.] I received Alpha Brain in exchange for my honest opinion. Incentivized. After taking this for 2 weeks I have definitely noticed a difference in my focus and memory. It took about a week to kick in but after that I definitely feel a lot more focused. It has helped me feel more productive during the day. It is definitely a great motivational tool.

No improvement

[This review was collected as part of a promotion.] I didn’t find this product improved much of anything after 30 days of taking it. It claims to promote mental clarity and help with focus and reaction time and I didn’t experience any of that. It doesn’t taste like anything which is good, but I definitely would not have purchased this product.
