Effectiveness

I’m an aircraft structure technician that uses computers to assist me in overhauling sheet metal components, I day trade stocks, and also enjoy playing competitive online games. I believe this has improved my ability in these but also any aspect of my life, the difference is slight but noticeable and effective. Brings clarity when trying to problem solve and create a plan.

Get yourself some Alpha Brain!

I highly recommend Alpha Brain! I’m a very scatter brained person that has a hard time sitting behind a desk. With the onset of Coronavirus, this has been my new reality. Alpha Brain has given me the ability to sit behind my desk for 8-9 hours and power through the work in front of me. I feel more focused, engaged and creative! This product is worth the cost.

Great product, highly recommend.

Im normally not one to review a product. This honestly might be my first, but I do truly believe in and enjoy the benefits of taking Alpha Brain. I take it Monday through Friday as I’m a college student and find it much easier to focus in my classes and complete tasks throughout the day. Not only does it help me with productivity and focus, but I also feel a sense of elevated mood through the day and feel that even conversations and interactions with others are easier and more enjoyable. Highly recommend.

Helps me stay sharp!

I first heard about Alpha Brain on Joe Rogan’s Podcast a long time ago, and finally, around about March of this year I decided to give it a shot. I just started a new job at a customer service center for an insurance company and there was a lot of training ahead involving stuff I’ve never learned before. Alpha Brain helped me tremendously! I was able to stay focused all day and retain all the information. I still take it every day before work because I talk to around 50-60 different people a day, and I stay sharp and am able to assist them without any sudden “brain farts”.

True Gut Relief

[This review was collected as part of a promotion.] I was skeptical at first. I've tried a few probiotics over the years, and they mostly felt like I was just spending money on hope. This one, however, was different. The First Few Days: I have to be honest—the first three days weren't miraculous. I felt some extra rumbling and gurgling in my stomach. I think that was just my body getting used to the new ingredients. It wasn't painful, but it was noticeable. It was a sign that things were actually changing, not just passing through. The Real Change (Week One Onward): After that adjustment period, everything went smoothly. The first thing I noticed was how much flatter my stomach was. My usual afternoon bloat, the kind that makes me feel like I have a basketball under my shirt, was greatly reduced. That alone was a win.But the biggest change was regularity. Before, my routine was unpredictable, which created stress in the mornings. With this supplement, I found a steady rhythm. It made me feel lighter and less sluggish overall. The "Extra" Factor: I really believe the combination of bacteria, fungi, and especially the digestive enzymes is what makes this work better than other brands. I could eat things that used to upset my stomach—like certain fibrous veggies—without as much impact. It felt like my entire digestive system was working at its best, instead of struggling through every meal. If I had to sum up my experience in one word, it would be "relief." It's not just that my digestion improved; it's the mental relief of not constantly worrying about gas, bloating, or needing to find the nearest bathroom. It's a real improvement in how I feel every single day.

So far so good…

I’ve used this for about three weeks now in an attempt to help me lose the brain fog that is associated with recovery after a major valley fever infection has cleared up (along with a lot of other stuff like more meditation and reading, increased cardio…). It has for sure had mental effects because I’m dreaming more vividly but also have more trouble remembering them than usual (weird considering the nature of the supplement, but it’s a clear mental performance difference so worth mentioning), but in daily life I do feel like I’m getting more done that requires mental acuity. I mention the dream thing first because it was more immediate, and made it seem to me like the waking effects were less likely to be placebo. Anyway, it’s pricey but if you can afford it I would recommend giving this a try - I first did a free two week sample offer and then ordered it in bulk to save a bit since it seemed to be working.

Great for both work and music

Alpha brain helps me be more productive and focused at work without all the negative affects of other stimulants. But I think it’s even more helpful when I’m playing shows. I’m able to be more present and feel in a flow state with alpha brain. Highly recommended.

Monica S

I'm not a person to ever leave bad reviews but when I take Alpha Brain my heart starts pumping and I start getting a little bit of anxiety and I don't know if this helps but I start drinking water then I get extremely sleepy. I am a newly widow and when I seen the add for Alpha Brain I was hoping that it would help me because I'm depressed and have to force myself out of bed every day but it does not give me the effect that Alpha Brain is promoted it is suppose to do.

No noticeable effects what so ever

Bought the Twin pack offer, Started with 2 pills the first day, nothing, tried 3 pills the next day, as I am also over 200 pounds which the bottle suggests, still nothing, One Saturday i tried 4 pills at once, again nothing. And by nothing, there was no effect on my "bouncing around the room" thoughts, no ability to focus better. I mean no tingling, no upset stomach, no racing heartbeat, no sweating, didn't make me dizzy. It was as if i really didn't take anything at all, except the gag reflex trying to swallow three horse pills at the same time, I listened for about 3+ years of the effects, and people complaining about how the earlier formula was better, and Praise from celebrities, and the extensive podcasts over this product, but to not feel anything ........ I really feel like a sucker for falling for the hype.
