Must have brain function booster

[This review was collected as part of a promotion.] Onnit Alpha Brain is really great supplement for brain cognitive functions like memory, reaction and focus. We were really pleasantly surprised to see how amazing supplements are added. For example, Cat’s Claw that is known for its immune boosting effects or variety of amino acids that our brain cells cannot function without.

Mental Clarity

[This review was collected as part of a promotion.] Very effective during study cramming for my upcoming test! Wish there were more for a longer trial to really test longevity of it. They are pretty expensive, but they work! No aftertaste, and they go down easy with any liquid!

Pricey with mild results

[This review was collected as part of a promotion.] I like the idea behind this product which is that it supports memory, promotes focus, promotes mental processing, helps with flow state (the feeling of being "in the zone" and is gluten and caffeine free, but I don't care for the high pricetag or the fact that two pills at a time is required for one dose and I only noticed vague results. I'm sure if I took more it would probably have a more prominent effect but I shouldn't have to exceed the recommended dose to experience decent results. I like that there's L-theanine as a main ingredient but I can take that for far cheaper on its own. I would recommend this to those looking for mild improvement in their focus and/or concentration and don't have a lot of distractions around themselves as it is, or those with a ton of money to burn and can afford the high cost of this product but aside from that I find it just okay.

No immediate changes of clarity for me

[This review was collected as part of a promotion.] I haven’t noticed any immediate changes after taking this supplement. I have been taking it for over two weeks now, so maybe it takes longer to go into effect. I did try taking it on an empty stomach, which was not a great idea. I highly recommend taking this product with food!

I tried Alpha BRAIN and overall, I liked it.

[This review was collected as part of a promotion.] I tried Alpha BRAIN and overall, I liked it. I could feel a noticeable boost in focus and mental clarity not long after taking it. It didn’t last the entire day for me, but it was enough to help me power through a few hours of focused work. I appreciate that it’s caffeine-free since I’m sensitive to stimulants. It’s a nice option if you’re looking for something to help you zone in without the jittery side effects of coffee or energy drinks.

Work okay

[This review was collected as part of a promotion.] I was super excited for these supplements!! I do notice a little bit of a difference when I take them! I feel like they helped me stay focused a little more than normal. I wouldn’t say it’s a drastic change though.

Great for focus and energy.

[This review was collected as part of a promotion.] These capsules are easy to swallow and I took 2 daily with lunch. They did seem to help with focus and energy during midday crunch when I tend to get tired and burned out. They come in a sleek, and easy to open bottle. I would prefer it to have a childproof lid. Overall, they work well for focus, memory and energy.

A must if you want more energy and memory back

[This review was collected as part of a promotion.] I am someone who likes to take vitamins that actual help me. With these vitamins I feel like I have more energy but also remember more than what I used to. It doesn’t taste like anything which make it easier for me to take them. Love that it comes in a capsule which is easier to swallow and also has amazing ingredients. You do get a lot in one bottle which will last a full month.

Alpha Brain

[This review was collected as part of a promotion.] I like the concept behind this supplement because I am all for increasing my mental clarity, focus, memory, and cognitive processing speed! I like the packaging. I only took 1 pill a day because the bottle only comes with 30 pills and I didn’t want to run out so fast.
