Ok

[This review was collected as part of a promotion.] I had to give this one a lot of time to see if it worked. Ingredients are okay. This was a good size. It didn't make me feel weird or anything, but I drink coffee and can't tell the difference. It's not great, but not bad. Complimentary of influenster.

Saved my life

I have dealt with severe brain fog my whole life. I was desperate to gain focus and memory. I have been on it for 3 months and I saw a huge difference.. by the 2nd day of use I had no brain fog at all and my memory was noticbly better. I will use this for the rest of my life. I really can't recommend this product enough. Thank you onnit

Waiting for results

[This review was collected as part of a promotion.] I haven’t really seen any changes yet, so this is why I reviewed this way. I do like that you get a lot in the bottle, and that it’s made with trustworthy ingredients! I just didn’t see a change for myself. I am continuing with them to see if anything happens. I do think the packaging is nice, and the taste is not bad

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!

Caffeine free supplements that work!

[This review was collected as part of a promotion.] Onnit’s Alpha Brain supplements are great for improved focus and mental clarity, memory recollection, while also being caffeine free. I do recommend testing out a smaller dosage first as there are some side effects (I experienced a bit of nausea). Also, make sure you are not taking this on an empty stomach!

✅ 1. It's a nootropic supplement Alpha BRAIN is d

[This review was collected as part of a promotion.] I've been using Alpha BRAIN for a while now and have really enjoyed it. I love that it's made with naturally sourced ingredients and that it's focused on supporting functions like focus and mental clarity. What I appreciate most is that it hasn't caused me any discomfort and is easy to incorporate into my daily routine. I will definitely continue using it and would recommend it to anyone looking for a supplement to support their daily mental activities.

Focoused and Clear

[This review was collected as part of a promotion.] I tried Onnit Alpha Brain because I wanted something to help with focus and memory, especially on busy days. Right away, I liked that it doesn’t have caffeine, so there’s no worry about feeling jittery or crashing later. After using it for a bit, I noticed I was able to stay more mentally “on” and focused, particularly when I had to juggle a lot of tasks or stay creative. The ingredients list is interesting that are meant to support brain health in a more natural way. For me, it gave a subtle but noticeable boost in clarity without feeling overstimulated. It’s not like a magic pill, but for days when I need to feel more mentally sharp, Alpha Brain has been a great addition. It’s worth trying if you’re

Caused loss of ability to speak and motor function

About an hour after I took the two capsules (as instructed by Onnit), I thought I needed to go to the hospital. I was trying to articulate something to my husband, and I could barely form a sentence (beyond frightening all on its own). Shortly after, muscles all over my body started to periodically twitch to the point where I needed to lay down in fetal position. When I tried to stand and walk, the effort felt enormous and I was afraid I would collapse. I eventually also experienced nausea. In a panic I researched reviews on the product and found many on various websites that said they experienced the same thing and that it will eventually subside, which is the only reason I didn't make my husband drive me to the ER. Instead of having the productive day I expected, I spent it trying to sleep it off. I'm not going to knock brain supplements because most are excellent, but the particular blend in Alpha Brain is extremely dangerous. If it were only myself that had this experience, I wouldn't say this, but the amount of people who are saying they had the same reaction is unacceptable. I do NOT recommend this product- what happened to me and many others is not normal, it's disabling and unsafe.

I’m not sure it did anything

[This review was collected as part of a promotion.] Tried Alpha Brain for a month hoping for laser focus and mental clarity… but honestly? My brain stayed on the same frequency 😅 Did it hurt? No. Did it help? Ehh, not really. Not sure I’d recommend 🧠

Great product

[This review was collected as part of a promotion.] I was hoping to find something to help me keep the daily focus that I need to run my small business. It has done everything I hoped for… plus a huge extra unforeseen bonus. I got for great value, I love the taste. Natural ingredients and love the packaging. I will get again
