Love how this works to make me more focus.

[This review was collected as part of a promotion.] A very cost efficient product that will make you think more clearly and keep you focus on whatever you are doing. The taste is very good and the ingredients are great. It comes in a very neat bottle.

effect is not too strong

[This review was collected as part of a promotion.] I tried Alpha Brain. It helps me stay more focused and gives a sense of mental clarity. The effect is not too strong, but I noticed better attention and memory. I also like that it only requires one capsule a day

Thumbs up

[This review was collected as part of a promotion.] I like this alpha brain daily cognitive support supplement. It doesn't have a taste and not much of an odor. The bottle is easy to open. The price is expensive especially since it comes with 30 but you need to take 2 a day. It did give me clearer thinking. I do recommend this.

Clear Focus

[This review was collected as part of a promotion.] Always check with your doctor but this has helped me. I was skeptical but I do feel like I can focus without my brain wandering off to different distractions. Its a simple packaging the capsules are standard size. They work great worth a try.

Alpha Brain

[This review was collected as part of a promotion.] This vitamin is the ultimate way to get focused. And it’s caffeine free yes I’ll take that. The packaging is nice simple but nice. I think for the price it’s a good amount inside. Take it with a light meal and you’re ready for the day!!

Brain Waves

[This review was collected as part of a promotion.] Received from Influenster to sample and review. Easy to open bottle/ packaging. I really didn’t notice any taste and had no issues with it being swallowed. Looked up the price and I think it’s pretty reasonable and consider far value compared with similar products. I would buy other supplements from this brand.

Noticeable results!

[This review was collected as part of a promotion.] Whether it was placebo effect or not, I felt a noticed improvement in my focus and energy almost immediately! It seems to provide similar energy to an energy drink, but I never felt jittery. The pill is a bit on the larger side, but other than that, I have no complaints. I didn’t notice any taste, and I appreciate that the ingredients are vegan

Easy to swallow

[This review was collected as part of a promotion.] I love how this comes in easy to swallow capsules. It is easy to remember to take them as it is only to be taken once per day. Doesn’t seem to hurt my stomach at all which is a plus to me. Haven’t really noticed a difference in memory, but since I’ve only been taking it for a little under 2 weeks I believe it may take time to see full results.

Focus Without Caffeine – My Go-To for Productive D

[This review was collected as part of a promotion.] As a working mom, I often find myself overwhelmed with multitasking — work, home, kids, projects… Sometimes it felt like my brain just couldn’t keep up. ⠀ During especially busy periods, I decided to try Alpha BRAIN® by Onnit — and it truly made a difference. It helped me stay focused on what mattered most, finish tasks, and not miss important details. ⠀ I also really appreciated that the supplement is caffeine-free — that was important to me since I try to avoid stimulants. ⠀ Alpha BRAIN® helped me get into the right mindset when I needed it most and made me feel mentally sharp again. I’m very happy with it and will definitely use it during high-stress times.
