Alpha BRAIN® boosts focus, clarity, and memory wit

[This review was collected as part of a promotion.] Alpha BRAIN® by Onnit has been a great addition to my daily routine. After a few days of consistent use, I noticed improved mental clarity and better focus during work and study sessions. It helped me stay sharp without any jitters or crashes, unlike some caffeinated alternatives. I also felt a subtle boost in memory retention and quicker reaction times. It’s a solid supplement for anyone looking to enhance cognitive performance naturally and stay on top of their mental game.

Focus & Energy Boost Without the Caffeine

[This review was collected as part of a promotion.] I've been taking Alpha Brain for about a week and have enjoyed the boost of focus and energy that it gives you. The capsules are easy to take and don't have any weird taste. Good option to check out if you are looking for a caffeine-free focus or energy booster.

alpha brand

[This review was collected as part of a promotion.] Useful for daily cognitive support as it helps to focus and memory as well as reaction time. Is usually taken to capsule with the light meal. Does not have any smell and it just swallowed it with water.

Thanks for reaching out and leaving a review! So sorry to hear that Alpha Brain did not work for you. Because everyone reacts differently to supplementation it's not uncommon to have different experiences. Please note that this supplement's main focus is to help support memory, focus, and processing speed - sometimes it can take time to notice these effects. That being said, if you are ever dissatisfied with your order, you can always contact our Customer Service team for further assistance!

Worth giving it a go

I have completed my first three weeks. To summarise, I am satisfied it has had a positive effect in improving focus, sharpness and memory recognition and recall. Note - I am a 22 y/o male at 77kg/179cm, I work out 5 days a week and I sauna 3 days a week. I drink alcohol on weekends. Focus: I noticed within my first week I was able to knock out mundane tasks at work with ease, freeing up my time to actively find more work. Memory: subjectively I haven't noticed anything out of the ordinary, although I have noticed that I haven't had any moments where I have struggled to remember anything that should be easily recalled. Dreams: The amount of dreams I've had have increased slightly and when I dream I notice that they are very visual. I note that I wake at 5.00am so sometimes I miss the opportunity to enjoy a full REM state. Overall, I have noticed that my lowest point of concentration and focus has been at a higher point than usual. Still early days and I look forward to seeing how I go after my first bottle is finished

I don’t think it works

[This review was collected as part of a promotion.] I feel like the ingredients are not in large enough quantities to have an effect. Also you have to take two at a time. The packaging is easy to open it doesn’t have a taste. The FDA doesn’t regulate supplements so I don’t think it’s the best. Please like if this helps

Good ingredients

[This review was collected as part of a promotion.] I have tried other supplements from this brand, and have been happy with those, so I was pleased to start taking these. I have been taking these for a short while, so I can't give a long term use result. As for the time I have been taking these I do see myself being more focused during certain tasks, but cannot say whether it is from these supplements or a combination of these and others I take. Time will tell

Easy to swallow and effective

[This review was collected as part of a promotion.] My husband and I both started taking one pill to try out. We noticed results on the same day. My husband shot an amazing score on the golf course. I accomplished the most I have in a day as far as doing house chores efficiently. It is easy to swallow and does not have a thick outer coating. There is no flavor or weird tasting burps. The packaging is convenient and easy to open.

Doesn't work for me.

[This review was collected as part of a promotion.] I am sorry to say but these did not work for me. I don't know what this brand puts in their products but this is the second product I have tried and nope not for me. Something in them makes me lightheaded and nausea.

Give it a try

[This review was collected as part of a promotion.] I received the Onnit Alpha brain memory and focus daily cognitive support dietary supplement 30 capsules from Influenster for free an exchange from my honest review of the product. I love that the supplement is gluten, free and caffeine free. The pills are very easy to take and does not leave a bad aftertaste. It absolutely helps with my mom foggy brain and I have more energy. I can definitely see a change and I will be purchasing this in the future. I definitely would recommend it to anyone to try it.

Pretty helpful

[This review was collected as part of a promotion.] So far, this feels effective. The taste isn't too bad, and the ingredients are great. It has a vegetarian capsule, so it could appeal to those who do not use meat based products.the label gives all the info needed. So far, I like them !
