Not sure...

[This review was collected as part of a promotion.] From the research I did, this seems to be a good brand. The list of ingredients is good too. I didn't notice an improvement in my ability to remember things, but maybe I needed to take it longer? I'm not sure...

Focused!!!

[This review was collected as part of a promotion.] I received this the other day and have only been taking for about a week. I do feel more focused and stimulated mentally. My mind feels a little less boggy and has a little more clarity with my thought process. I look forward to seeing how the rest of the trial goes.

awesome stuff. would recommend!

I bought this stuff thanks to joe rogan and i'm a sceptic. after the first dose I was feeling ON POINT & FULL of energy. I was rushing around getting it done son, but not in a illicit drug style or over hyperactive state just sharp and clear. Honestly the 2nd day I took em before work with some breakfast (9am) and that day was a positive and fun day. I also worked like a champion(construction). from then on it was smooth sailing until now.. that Im out and need more haha. so yeah It worked for me. love it. thanks guys!

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.

review

[This review was collected as part of a promotion.] My husband was excited to try these, while the capsule is quite big.. there is no taste. After almost two weeks he started to feel a slight difference and he will continue taking them to feel better.

Supporting memory, focus, and reaction time

[This review was collected as part of a promotion.] Thanks to Influenster and Onnit for this Alpha Brain product. This dietary supplement helps support focus, memory, and cognitive processing speed. It's caffeine-free, making it suitable for those who are sensitive to caffeine. You can start with one capsule and increase to two daily.

Clear Focus Without the Jitters !

[This review was collected as part of a promotion.] I’ve been using Alpha Brain for a little while now and I’m really impressed! The ingredients are clean and natural — no weird stuff, which I love. The packaging looks nice and feels premium. Taste-wise, I tried the capsules so there’s no strong flavor, which is a plus for me. In terms of value, it’s a bit on the pricey side, but I think it’s worth it for the quality. Most importantly — it actually works! I feel more focused and clear-headed, especially when I have a busy day ahead. Definitely a great support for productivity.

Worth the try!

[This review was collected as part of a promotion.] ingredients and quality are great, I do think I would need to take it longer term to truly see if the effects are long lasting and if it is really effective. Has no taste and the capsule is easy to swallow. Pricing is on the higher end but reasonable.

Mind Crisp

[This review was collected as part of a promotion.] Very easy to swallow, I have taken 2 capsules daily for a week and my mind feels a bit more crisp. I will say, at 45 years old I have no issues with memory loss, so this may be more effective for some that do. Worth a shot.
