Great

[This review was collected as part of a promotion.] This is something that will help my husband out tremendously. In the days he remembers to take it he has reported feeling a bit more “in charge” of his thoughts. He hasn’t reported anything on taste.

Incredible

[This review was collected as part of a promotion.] Gifted by Onnit. I’ve been trying Alpha Brain for a few days now, and I’m pleasantly surprised by the results. These capsules are easy to swallow and don’t upset my stomach. I’ve noticed an improvement in my focus and mental clarity, especially during busy mornings when I need to stay productive. My memory also feels sharper, and my reaction time has improved when multitasking. It’s a great supplement if you want extra cognitive support throughout the day. I also appreciate that it’s designed to support focus, memory, and reaction time—all in one formula. Definitely worth trying if you want to boost your mental performance!

Stay on task

[This review was collected as part of a promotion.] I was excited to try these and I feel like they do work! I feel like I got a lot done and stayed focused, the down side is there are 30 capsules so you think you have a months worth of supplements but on the back of the bottle it says a serving size is 2 capsules a day. So you’re only getting about 2 weeks worth of supplements. It’s in a convenient capsule which makes it easy to take and has good ingredients I just wish it came with a least a months worth in one bottle

No bad taste at all

[This review was collected as part of a promotion.] Great packaging, it was completely sealed and a little difficult to open but that’s good. I didn’t feel any bad taste or bad after taste, just like a little herbal while you have it in your mouth. I do feel more focused.

My Brain is JACKED

While taking Alpha BRAIN the last few months I have not noticed any conscious differences in how I feel physically or mentally. What I have noticed is the following: First, when drinking a few cups of coffee in the morning and then taking the recommended dose of Alpha BRAIN in the early afternoon by evening my brain is so wired I cannot sleep at night. After doing some Googling I saw some recommendations by other users to take it in the morning with breakfast. I've switched to the recommended dose of Alpha BRAIN and one regular cup of coffee late morning to get back to sleeping regularly. If I drink extra coffee or miss taking Alpha Brain in the morning I take half the recommended dose...or sometimes skip it altogether if I haven't slept in 1-2 nights. Secondly, I've noticed changes in the way co-workers and upper management have responded to my work and within our recent interactions. Always felt like my efforts and overall body of work were under appreciated. I have a tendency to be too wordy and not straight to the point...not by design. I just freaking ramble. Looking at Joe Rogan's comments about formulating sentences better, faster has me wondering what the heck is up with my brain because as that's how I feel and I can see it in peoples reactions. I've never taken supplements before for for the purpose of being a nootropic. Doing some research I've noted that I'm already consuming things that are considered nootropics (caffeine, creatine). Based on the affects I've noticed in my interactions with others while taking Alpha BRAIN it will remain part of the arsenal. Cheers.

Brain Pills

[This review was collected as part of a promotion.] These pills are supposed to enhance brain function. I would say I did not notice much of a difference in my brain enhancement. The pill is very large. It does not have the greatest taste if you accidentally touch your tongue to it while trying to swallow. It has only a very mild odor, unlike some others that can be very fishy smelling. I did make sure to drink plenty of water with it. Sometimes it makes your tummy mildly upset. I don't think I would use this product in the future.

Great!

[This review was collected as part of a promotion.] I've been taking Onnit Alpha Brain for about a month now, and it's honestly made a big difference. My focus and mental clarity have noticeably improved—| feel more alert, less distracted, and better at remembering details. It's not like a caffeine rush, more of a smooth and steady boost that helps me stay in the zone. No jitters, no crash, just a clear head and better productivity. It's definitely earned a spot in my daily routine.

Helps me stay on task and focus on my daily goals.

[This review was collected as part of a promotion.] This didn't seem to have a bad taste like I expected. It definitely helps me focus on my daily tasks. The ingredients make me feel good about taking this. The packaging was appealing. The only thing I don't love is the cost.
