Brain power

[This review was collected as part of a promotion.] Easy to read packaging. I believe that they do help with some mental focus. I only took them on days I was needing a little extra at work. I didn’t “taste” them, I just swallowed the pills and moved on. I would recommend

Sick, nauseous, dizzy

[This review was collected as part of a promotion.] I received this product for free from Influenster in exchange for my honest review. Wow this is the worst supplement I have ever taken. I took 2 capsules (the serving size) after a *light meal* as recommended, and about an hour later I was feeling dizzy, nauseous, and sweating. Multiple times I felt like I was going to throw up but luckily didn’t. After taking them (which was my fault for not doing enough research) I found others have felt similar side effects after taking them for the first time. It took about 5 hours and a good night sleep for me to feel back to normal again. Safe to say I will be discontinuing my use of them. They didn’t taste like anything, and the packaging seemed to be appropriate for the contents inside; it also seems to be very pricey for only 30 capsules. I am glad they work for others, but just be careful and aware of the potential side effects it may have for you.

Not really feeling any different

[This review was collected as part of a promotion.] I’ve been having trouble focusing lately, so I was glad to try this product out, but I haven’t noticed any real difference in my memory or focus. Of course I will continue using this product to see more of a difference long term, but as of right now I don’t notice any difference.

Fine, I guess

[This review was collected as part of a promotion.] Decent supplements. No caffeine in the ingredients, so those sensitive to it won't have to worry. It didn't have any discernable taste, and the 30 capsules last 15 days, so I couldn't really judge if it was effective when added into my usual routine.

Promotes cognitive functioning.

[This review was collected as part of a promotion.] Was excited to try this product. It is supposed to support cognitive functions, memory, mental speed and focus. Tried this during Ramadan fasts and felt like there was some boost in cognitive function while fasting. Perhaps longer term use would unveil more pronounced effects. The pills are large and are supposed to take 2, there is however no taste or any aftertaste.

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.

I do not see a difference in performance

[This review was collected as part of a promotion.] I don't know much about the ingredients in this product, but I was excited to try a caffeine-free cognitive support supplement. This product promises to help with mental clarity, memory, and focus. I have tried it for about a week but have not noticed a difference in my performance. Maybe it takes longer for this product to start working, I'm not sure. On a positive note, I haven't noticed any adverse effects while taking this supplement.

Normal

[This review was collected as part of a promotion.] I’ve already been trying this product once a day for a week, and I haven’t noticed any significant difference. Maybe I should use it for longer or before doing a specific activity so that I can notice the effect.

Sharp Mind, but Upset Stomach: Alpha BRAIN Review

[This review was collected as part of a promotion.] I received Alpha BRAIN from Influenster to try and give my honest feedback. The supplement is widely known for its effectiveness in supporting focus and mental clarity, and I noticed a boost in cognitive function after using it. The ingredient quality seems solid, with a blend of well-known nootropics that target various aspects of brain health. The packaging is sleek and professional, which adds to the overall appeal of the product. When it comes to value for money, Alpha BRAIN® is on the pricier side, but considering the potential cognitive benefits, it might be worth it for those who prioritize mental performance. However, I did experience one downside: the supplement gave me nausea after taking it. This could be a personal reaction, so I plan to try it again after eating to see if it helps. The taste isn’t particularly pleasant either, but it’s manageable since it’s in capsule form. Overall, Alpha BRAIN shows promise in boosting brain power, but the nausea was a drawback for me. Hopefully, taking it with food will make a difference.

It’s ok

[This review was collected as part of a promotion.] I’m a person that it’s always moving around and doing a lot of stuff at the same time but also tends to forget everything. I tried this to see how it works I did get more focus while taking them. Didn’t like the after taste but it’s ok because it’s natural.
