Made me feel sick

[This review was collected as part of a promotion.] I had high hopes for this product but unfortunately it didn’t live up to expectations. I only took one pill, after eating my breakfast. It was fine at first, I thought ok got a little spike of energy. But after that my body started to feel really weird. Then I got really nauseous. I felt off for the rest of the day. I did not have a good time at all. I’m giving it three stars because even though it didn’t work for me, I feel it could work for other people! One of the ingredients probably just disagreed with my body.

Brain. Focus

[This review was collected as part of a promotion.] This product is very clever. I’m definitely a person that needs help focusing as I have three children that pull me three different way ways. They taste like prenatal to me which is fine. The packaging is pretty cool. A great product. 8/10

Maybe not for me but would recommend everyone try

I've been taking two pills every morning for two weeks now (don't take it on the weekends as many reviews suggest to give yourself a bit of a break now and then). I start every weekday with fasted cardio and take the pills followed by a very light snack. You can feel the synapses firing up at the start of the day but I really haven't noticed a tangible difference in focus throughout the day. The most impactful result for me has been dreams, though. When I first got the bottle I popped just one pill about 3 hours before bed. I noticed I struggled to get to sleep that night (probably self-induced expecting a 'limitless' pill based on many other reviews). So I haven't taken except for in the mornings since then. However, I remember my dreams much better and they're freakishly vivid at times - like, sometimes I remember something happening then can identify that I actually dreamed it. That aspect is very cool but I can't endorse the current price tag for the limited benefits I've received after a couple weeks of regular use. Looks like it is a lifesaver for most, though so I recommend everyone give it a shot!

Mental clarity for those constantly on the go

[This review was collected as part of a promotion.] As a person who constantly finds themselves juggling the chaos of work along with everyday activities, Alpha Brain Memory & Focus has been a game-changer for me over these past weeks. The stress and sleep deprivation are daily struggles, but this supplement has allowed me to stay sharp, focused, and definitely alert at work and home when I needed it most. Whether it’s tending to the needs of family or customers, I’ve felt more mentally clear and on top of my game. I've experienced no jitters or crash—just a boost of energy and clarity. I’d recommend this product to anyone needing a mental boost during demanding times! It's time you invest in your personal health.

Keeps me focused and alert

[This review was collected as part of a promotion.] I've been using this ONNIT ALPHA BRAIN Memory & Focus supplement for the past few weeks, and I can truly say I feel much more focused and alert than usual. These capsules are easy to take and have no after taste. I like the packaging of this product it's very minimal. This product is budget friendly. I absolutely recommend this product.

Sick for hours

My partner has taken this supplement without negative reactions; however, it is worth noting that I puked on myself and in my car after taking this supplement. I took as directed with a light meal and was sick for hours. It definitely isn't for everyone. I even gave it a second chance and had the same results.

Alpha Brain

[This review was collected as part of a promotion.] Alpha BRAIN is a solid option for anyone looking to improve focus and memory without stimulants. After a few days, I’ve noticed better concentration and mental clarity. The natural, caffeine-free formula is a huge plus. Excited to keep using it and see how it works over time!

Okay

[This review was collected as part of a promotion.] I’m not a big fan of large pills but these were easy to take. Packaging was not hard to open. There was no bad taste. As for its effectiveness I didn’t notice much focus going on. I was hoping it would help me zero in on some tasks but I didn’t notice a difference. I might work for others as it does have great reviews.

If you are into vitamin enhancing supplements, you should try this product.

[This review was collected as part of a promotion.] The packaging of this product was secured. The taste definitely reminded me of multi vitamins. It is worth the price. The it took me a while to notice if it worked or not but I slowly start to notice things. I was a little more alert.
