Helps Support Mental Clarity

[This review was collected as part of a promotion.] I like how these help restore my focus and mental clarity. They contain L-theamine, and amino acid that helps me concentrate better. I take them every day to help me be more productive and accomplish my tasks. I like that they are in capsule form and easy to take. I don't notice any taste when I take them with water. They come in an easy to open bottle.

Looking to continue seeing the use

[This review was collected as part of a promotion.] Excited to continue using. I love taking supplements to help myself. These have little to no taste and it’s quite tolerable. I will say looking at it it’s quite pricey but I hope it continues to do what it claims to so I can buy it myself after this is done.

No smell, no taste

[This review was collected as part of a promotion.] I’m gonna take those vitamins for about a month and I have not seen any significant improvement in my brain functionality. Not sure if I just need more time or is it just doesn’t work . On the positive side the pills are nice size and easy to swallow with no unpleasant smell or taste.

Good option to have?

[This review was collected as part of a promotion.] Honestly my husband didn’t notice any significant change in anything after taking this supplement. It doesn’t taste like anything , the pill is a normal sized pill ( not hard to swallow ) . The packaging is average. Overall you don’t lose anything from taking it? But I also wouldn’t go out of my way to buy it again.

Great vitamins for the brain.

[This review was collected as part of a promotion.] These are absolutely effective. They work amazing and the ingredients are top tier. The packaging is easy to understand and it's a great price. You don't really taste them cause you swallow them whole so it's easy as ever to use.

The packaging is great and it’s easy to take. I ha

[This review was collected as part of a promotion.] I’ve been trying it for a few days now. The packaging is great and it’s easy to take. I haven’t noticed major changes yet, but I’m curious to see how it works over time. I like that it’s caffeine-free and targets focus, memory, and reaction time—hoping to feel the full effect soon!

Good

[This review was collected as part of a promotion.] Great product my husband has been using this he said it’s been helping it’s his memory and he can focus a little better so I guess it’s working at least for him! He said it had a little bit of a bad taste but taking it with something to drink helps!

Huge fan!

[This review was collected as part of a promotion.] I am a huge fan of Alpha Brain and the truth is I need to increase the amount I purchase. I buy it every few months and it makes a huge difference in my cognition and communicative skills. I would love to take it every day if I could.

Seem to be helping

[This review was collected as part of a promotion.] This is a product I received for free from @Influenster and @onnit in exchange for my honest review. Well, I don’t know much about the ingredients that are in here however they do seem to be effective. The packaging is pretty. I don’t notice any weird taste or anything which is nice and then they aren’t really any more expensive than any other supplements.
