Didn’t actually work for me

[This review was collected as part of a promotion.] I received this product complimentary from @Influenster and @onnit in exchange for my honest opinion. Alpha Brain by @onnit is a daily nootropic formula that comes in a bottle of 30 capsules, with the recommended dosage being two capsules every morning, according to the label. It’s marketed as a supplement that helps support memory, focus, and cognitive processing speed—essentially aiming to enhance mental clarity and promote the feeling of being “in the zone,” also known as a flow state. For those who are curious, it’s a caffeine-free blend made with ingredients known for their potential brain-boosting properties, including L-Theanine, Phosphatidylserine, Alpha GPC, Huperzia Serrata extract, and Vitamin B6. The formula is designed to deliver nutrients that may help create a more optimized environment for cognitive function without the crash or jitters that often come with stimulants. However, after trying it consistently, I personally didn’t experience any noticeable changes in how I felt mentally or emotionally. I was still tired, unfocused, and just as stressed as usual, so for me, it didn’t live up to the claims. That said, everyone’s body responds differently, so it may still be worth a try for someone looking for a stimulant-free option to potentially enhance their daily cognitive performance. #complimentary #getonnit @onnit @influenster

Thanks for leaving an honest review about your experience with Alpha Brain! We’re bummed to hear that you didn’t have the experience that you were hoping for. While we typically suggest trying out for 2 weeks to feel effects, being that we all have different needs, it's expected that we all respond to supplements a bit differently, and we're glad you gave it a shot. -- Cailee B.

Noticeable boost in focus, but not without downsid

[This review was collected as part of a promotion.] If you’re looking for a nootropic that supports focus, memory, and mental clarity without caffeine, Alpha Brain is worth trying — just be mindful of how your body reacts and whether the results justify the price for you.

A nice vitamin

[This review was collected as part of a promotion.] This is a nice vitamin and I feel pretty energized and alert when I take it. Not sure if it’s the whole reason but I feel good! They have a little bit of a strange taste but nothing crazy. At first my belly was a little off, but it’s all good now!

Excellent

[This review was collected as part of a promotion.] I really liked this supplement because it helped me with stress, it gives me peace of mind so I can think things through better, it helps me focus better, and at the same time, I stay active in my daily routine. I recommend it because it's been helpful and it's very good quality.

ONNIT Alpha Brain – A Game-Changer for Focus and M

[This review was collected as part of a promotion.] I’ve been taking ONNIT Alpha Brain consistently and have noticed a real difference in my mental clarity and focus. It helps me stay sharp, especially when I’m juggling multiple tasks or absorbing a lot of information. I feel more alert and productive throughout the day—even during high-stress situations.

Boost for your brain

[This review was collected as part of a promotion.] I received Onnit Alpha Brain from Influenster for free, and I’ve been testing it for a few days. It really helps me stay focused and mentally clear, especially when I’m filming or editing content. No crash or jitters like from coffee — just smooth, clean energy. So far, I’m loving the boost it gives to my daily productivity!

Made me ill

[This review was collected as part of a promotion.] I unfortunately can't say much about efficacy these since it made me extremely nauseated to the point where I had to lay down all afternoon and sleep it off. It made me so dizzy. Not sure why I had a bad reaction but I wouldn't risk trying it again. The ingredients seem okay. The pills were scent free, without a distinguishable taste. They were easy to take but pricey for 15 days of servings in a bottle.

Would not recommend

[This review was collected as part of a promotion.] The Alpha Brain supplement was a disappointment. I was able to get past the nausea by making sure to take it after a full meal. However I had to discontinue taking it, because it caused me to have uncontrollable eye spasms for hours after.

Good

[This review was collected as part of a promotion.] It really helps me stay focused and clear-headed. The taste is mild and easy to take, and I love the clean ingredients. The packaging looks great, and it’s definitely worth the price for the boost it gives!

More alertness on my new job

[This review was collected as part of a promotion.] Thank you Onnit and Influenster for letting me try these supplements for free. I took my sweet time trying them and it coincided with me getting a remote job online so I really took these supplements to the test. My new job involves being on the computer for hours and I used to easily get worn out and mentally tired from digital stimulation. After trying the Alpha Brain supplement within this month, I felt a bit more focused and alert, without any feeling of nausea or mental exhaustion. I think I found a new partner for my job. Thank you.
