Surprisingly effective

[This review was collected as part of a promotion.] I’ve been taking these once a day (typically in the morning with a yogurt) before work and have definitely noticed a difference in my daily alertness. I will admit I was skeptical about trying a product like this for the first time but am seeing the impact and will be incorporating into my daily routine.

Focus boost

[This review was collected as part of a promotion.] I’ve noticed better focus and memory. It helps me stay on task without distractions and recall info more easily. The energy is smooth, with no jitters or crashes. No side effects, just sharper mental performance. Definitely worth trying if you want to boost focus and clarity.

Works but bottle smells

[This review was collected as part of a promotion.] This Alpha BRAIN supplement claims to support memory, promote focus and mental processing, and help with flow state. I did not try this supplement daily. I only tried it on days that I felt my brain was a little sluggish or days that I knew I needed to be more focused. Yesterday, I needed to work on some spreadsheets. I took the recommended 2 capsules after lunch. I immediately felt my mind got clearer. I was able to focus better and was in the zone for a few hours. There is no caffeine, so this supplement will not keep you awake at night. The one thing I did not like about this supplement was the smell whenever I opened the bottle. I do not know how to describe it, but it is simply unpleasant. However, when I took out 2 capsules and smelled them, I could barely detect the smell, so it is either the bottle that stinks or all of the capsules together make the smell stronger. Despite its smell, I do recommend this supplement to anyone who needs help with focusing and mental processing. My memory is pretty good, so I cannot attest to if it helped with my memory.

Meh

[This review was collected as part of a promotion.] I liked the packaging and design of the label. It told you what you should expect to help with the supplement. I wish it had the ingredients listed. I have no idea what was in it based on the labeling. I did take them as directed for the whole bottle. The capsules did not have any strong taste. Also they did not cause me to feel nauseous or any negative way if I took them in an empty stomach or not. I did not notice any difference in my memory, focus, or anything like that.

Could be worth a try!

[This review was collected as part of a promotion.] This product was fine! I don’t notice much of a difference after taking it. That’s not to say it wouldn’t work for other people. I enjoy the branding and packaging. Taste isn’t notably bad for what it is either.

Good size and easy to swallow.

[This review was collected as part of a promotion.] The package is good, with a sealed top. The pills are of reasonable size and easy to swallow. They have no flavor or bad taste. I've been using this supplement for a couple weeks. I feel I'll need to utilize them for a few more months before I notice a significant impact. The quality of the product looks good and I will continue using them.

Good!

[This review was collected as part of a promotion.] I was a little skeptical at first, but Alpha Brain really surprised me. I don’t feel wired or overstimulated. I was just clear-headed and focused. It’s subtle, but I notice I’m quicker with recall and stay more locked in during meetings or deep work. It’s become my go-to on days when I need to be mentally sharp without relying on caffeine. Definitely worth trying if you’re looking for a natural boost in brain function.

No improvement

[This review was collected as part of a promotion.] I didn’t find this product improved much of anything after 30 days of taking it. It claims to promote mental clarity and help with focus and reaction time and I didn’t experience any of that. It doesn’t taste like anything which is good, but I definitely would not have purchased this product.

Subtle difference?

[This review was collected as part of a promotion.] I love the idea of Alpha Brain. I love the ingredients, and feel some subtle boost in attention and productivity. It's hard to discern if I'm experiencing a placebo effect or if this is making a big difference. I will continue using this product.

Good ingredients for brain function.

[This review was collected as part of a promotion.] This supplement has a good blend of ingredients known for supporting brain function and clarity. There was not an immediate feeling of "clarity" after using for a month. But there was not anything making me feel off when taking it. Capsules went down smoothly and no after taste.
