Great supplement

[This review was collected as part of a promotion.] I like that this doesn’t leave me feeling jittery. I like that it helps keep me sharp throughout the day. I’ve been able to cut back on caffeine a little bit during the day which has been nice. Sleep seems better at night. There is no gross taste after taking them. They seem like a great quality and value. The packaging is fine for a supplement.

Highly recommend for anyone looking to sharpen the

[This review was collected as part of a promotion.] I've been using Onnit Alpha Brain for a few weeks now, and the difference in my mental clarity and focus is incredible. Tasks that used to take me hours now feel easier and more streamlined. I love that it’s made with natural ingredients and doesn’t give me the jitters like other supplements. Highly recommend for anyone looking to sharpen their mind and boost productivity!

Alpha Brain

[This review was collected as part of a promotion.] Packaging it came in tight sealed great bottle appeal information easy to read it's been a few weeks taking them, but I can't say I have noticed it big change, but I will continue to use and re update my review. Pills are a good size easy to swallow them

Great product!

[This review was collected as part of a promotion.] I’ve been using Alpha Brain for a few weeks now, and overall I’m pretty impressed. I mainly wanted something to help with focus and mental clarity without relying on caffeine, and this definitely delivered. I notice I stay sharper during long work sessions, and my thoughts feel a bit clearer, especially in the mornings. It’s not like some magic pill where you feel superhuman, but it does give a noticeable boost in concentration. The fact that it’s stimulant-free is a big plus for me since I don’t like the jittery feeling I get from other supplements.

Yack Attack

I followed the directions, had 2 pills after a light meal. Within 30 minutes I started feeling queazy, a bit dizzy and my stomach started doing circles. Very similar to feeling drunk. I was at work so after three trips to the bathroom had to call it day and head home. About two hours after taking the product I yacked my face off.

My wife and I are subscribers for life!

[This review was collected as part of a promotion.] My wife and I were listening to Rogan talking Nootropics and didn’t give it much thought until we both noticed recognizable decline in getting out our words and organizing our thoughts. We started Alpha Brain and since then we are clearer and can organize our thoughts so much better. We are subscribers and will continue to be for the considerable future.

Works wonders

[This review was collected as part of a promotion.] The neurotypical formulation is very effective, it’s caffeine free and improves your mood and helps focus. It has a good taste, quality ingredients and comes in a cute packaging . It’s so worth the hype and the price. I use it during my exams and it definitely helps I recived this product for free in exchange for a honest review.

Excellent

[This review was collected as part of a promotion.] Very satisfied with this product. I really needed it and will buy it again. From the start, you can see the results; I feel more focused. I recommend it for new moms; our brains will thank us for it.

No difference in mental clarity

[This review was collected as part of a promotion.] I used the Onnit Alpha brain for two weeks. I started out with one a day then went to two a day for the 4th-14th days. Unfortunately I did not notice a difference in focus or anything. It did upset my stomach when I went to 2 capsules so I’m not sure that it is a good choice for me. The bottle also only lasts for about two weeks if you take it as recommended, so it’s not a great value. Pretty expensive for me to try it for longer. I didn’t notice a taste or aftertaste so that’s always a plus.

Brain health

[This review was collected as part of a promotion.] I received this product for free in exchange for my honest review. I am using Onnit Alpha Brain supplement to help with my memory, concentration, and thinking time. The key ingredient is an amino acid L-theanine. It contains a few other ingredients that can play a role in neuro-transmission and brain cell health. So far I haven't had any side effects from it. I do feel a slight improvement in my focus and work efficiency. I haven't noticed a big difference in my memory at this time. I am happy to continue using this and see if I can gain some long-term benefits.
