Great Product

I’ve been taking Alpha Brain for at least a year. I have tried other such products and the one thing I’ve noticed is there is no ingredient label on the box or bottle. If the manufacturer can’t tell you what’s in it, don’t buy it. What I see in Alpha Brain is what works for me. Also, don’t think 1 or 2 weeks for any of these products works, for some it takes longer. This is a great product for me and I have tried others.

So far so good-

[This review was collected as part of a promotion.] As I've aged, I have noticed a drop in my memory AND focus. I gave this a shot and although my focus is still an issue, I find myself saying "um what was I talking about?" a lot less. I do find myself to be a little jittery though so trying to work through that.

Aids flow state but needs consistent evidence

[This review was collected as part of a promotion.] It could be placebo but I did find that I was able to focus and get into a flow state easier when taking these! The capsule is rather large but there’s no noticeable taste so it’s not unpleasant to take. I’m interested to see if I feel any long term benefits with consistent use- the one caveat is that a full dosage is 2 pills so these probably won’t last one very long.

Great for focus!

[This review was collected as part of a promotion.] I have been taking these alpha brain pills daily, since I was sent to review them. The pills are packaged quite large, but it goes down easily, without any bitter taste. There’s 30 capsules in each bottle. I have noticed a change in my energy and focus, which I really like! I would buy a bottle to continue taking!

Actually focusing more

[This review was collected as part of a promotion.] this was a fun try! the after taste is a little strange but overall not bad. i do feel like i focus better during the workday while using this product. I wish the daily dosage was in one pill as that would be more cost effective

Alpha Brain 🧠

[This review was collected as part of a promotion.] I took this for almost half of a week but I started experiencing different symptoms. I felt like it was working after a few days but I did feel more thirstier than usual. It started making me lightheaded after the 3rd day and had to pause taking anymore. I started off taking 1 capsule even though the recommended dose is 2. I feel this Alpha Brain can be more effective on some people rather than others due to many factors such as size, gender and tolerance . I myself would not buy its again. The price ticket is slightly on the higher side but if it works for other individuals, than its worth it.

Thanks for giving Alpha Brain a shot and for sharing your experience! Everyone's experience can be a bit different with a formula like this. It's formulated to help support memory, focus, and processing speed, and it can take some regular use to really feel these changes. We suggest trying it for at least two weeks and if you still aren’t happy we can help with some supplement tips and/or to help facilitate a return if needed. You can email help@onnit.com for further assistance with your order!

Back for more

I tried this supplement for two months, and when my subscription ran out I tried another brand. I'm baaaaack! With Onnit, I felt immediate results, and actually couldn't wait to get back on it after my break with another product. Looking forward to the next two months of total memory and word recall!

Good so far

[This review was collected as part of a promotion.] These seem to be working a little so far. I’m a little more focused when doing things at work and putting things together at home. They don’t taste bad but there is a small after taste to me after I swallow. I would give it a try if you think you need it.

Great for focus without the jitters

[This review was collected as part of a promotion.] I’ve been taking Alpha BRAIN for a short time now and I can already notice a difference. It really helps me stay focused and clear-headed, especially during busy workdays or when I’m studying. I love that it’s caffeine-free — no jitters, no crashes, just steady mental clarity. The fact that it supports memory and helps with that “in the zone” feeling makes it perfect for productivity. I feel more organized and able to concentrate for longer periods. It’s still early days for me, so I’m curious to see how it works with longer use, but so far I’m impressed. Definitely a good option if you want a cognitive boost without relying on stimulants.

Good product

[This review was collected as part of a promotion.] Seems to be found exactly what it claims to do. I've been taking for several days, and I can already tell the difference . I can't taste an aftertaste, and a long as I drink plenty of water, they go down easy
