Would not recommend

[This review was collected as part of a promotion.] I would never personally recommend these. After about 2 hours of taking the pills, I became extremely sick. Nausea with a headache for most of the day. I could not eat and the only thing that slightly helped was a short nap and Advil.

Seemed okay would need to take longer for full use

[This review was collected as part of a promotion.] This was a pretty good supplement I feel like I would have needed to take it for longer to be able to give it a full review. It did help a bit with focus and cognition but I didn't see a lot of change.

Alright

[This review was collected as part of a promotion.] Honestly, I did not notice a difference in cognition when using the supplements. Perhaps I just need to give it longer. There was only a 2 week supply in the bottle anyhow. I like the ingredients and how they combine herbs for both relaxation and focus. The supplements are a large capsule size, which made swallowing them hard sometimes. Not bad tasting good bang for your buck.

Appears good quality.

[This review was collected as part of a promotion.] Received Alpha Brain from Influenster for my honest opinion. The packaging is good and easy to access. The capsules are easy to swallow and don't have any bad smell or taste. They didn't cause me any negative side effects. I am not sure how to tell if they are effective. I think someone might need to take the supplement for longer. I would recommend giving it a try.

Clarity

Like with others that have reviewed this, it takes a couple days to identify the effects. The first thing I noticed was clarity, your mind seems to open up and able to take more in, process information more efficiently. The 2nd thing I noticed was In conversations around the office, my ability to converse seems more fluid and flows with ease. I put Alpha Brain to the test in a job interview. I took two pills an hour before the interview, the interview lasted 2 hours and I felt mentally on point the whole time, never missed a beat with answers and after a intense hour of being drilled I was able to fire back questions with ease and turn the interview around them. I have a 2nd interview this week and will definitely be arming myself with Alpha Brain for round 2.

Helps Focus the Mind

[This review was collected as part of a promotion.] Focusing and staying on task aren’t easy these days. Our brains are trained for distraction and short clips of something interesting. This supplement can assist with refocusing to where our minds need to be. Each bottle has 30 standard sized, easy to swallow capsules and serving size is 2 capsules - so it’s a 15 day supply - if you were going to take this every day. The ingredients are supposed to help “build an environment to optimize cognitive function” and help with focus, memory, flow and reaction time, according to the bottle. I like that these capsules do not contain caffeine. But, they do contain some very helpful ingredients that I’m familiar with including Vitamin B6, L-Tyrosine, L-Theanine, and Cat’s Claw Extract. I didn’t experience any adverse side effects from these capsules. They definitely help by supplementing your body with the right nutrients, but it’s not a Eureka moment either. Regardless, I think they work and they’re beneficial and something I would continue to use.

Makes you feel ready to go

[This review was collected as part of a promotion.] So this was definitely an interesting supplement to try and it was actually cool to see the effects. As long as I took this with some form of a meal I don’t feel nauseous so that’s definitely something I saw noticed best for me. You feel most aware and focused throughout the day and it works so quickly! Within 15 min I’m feeling ready to take on any task….there is no taste so that’s a plus on my side and I haven’t had any burps with awkward taste HA! The packaging is simple to the point of making it seem like the light in the dark foggy tunnel or maybe I’m overthinking it…but it’s great to give you a boost specially on days when sleep hasn’t been on your side.

My memory and focus improve tremendously!

[This review was collected as part of a promotion.] As a 37-year-old African American woman balancing life as a full-time teacher and a mom to a young child, mental clarity and focus are essential for me. I started using Alpha Brain hoping for a little boost—and I’ve genuinely noticed a difference. I feel more alert during my lessons, and it’s been easier to stay organized and present, even when the day gets hectic. It’s not a dramatic overnight change, but it helps me feel more on top of things without any crash or jitteriness. For me, it’s become a small but meaningful part of my daily routine !

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.
