They are good

[This review was collected as part of a promotion.] For the value they are good and effective they don't have any taste or at least didn't find the package it's nice and the ingredients didn't read em I couldn't finish them I got an accident so I couldn't finish them

Meh save your money

[This review was collected as part of a promotion.] Grateful to have received this product to sample, however; I wouldn’t say I noticed much of a difference. Experienced minor but uncomfortable side effects (headache, nausea) and an unnoticeable difference after weeks of use.

Eh

[This review was collected as part of a promotion.] I honestly don't feel any different. It's a bit of a bigger pill, which could be a problem for some people. It doesn't smell good, that's for sure. I don't know how I'm supposed to feel but I'm not noticing a difference unfortunately.

Helped me get through the day!

[This review was collected as part of a promotion.] I was excited to try the Onnit Alpha Brain supplement, because I really needed it. My mom brain is getting worse every year. It's packed with Vitamin B, which helps tremendously. 2 capsules a day and you're set. Great product, you gotta give it a try!!!

Worst supplement I’ve ever tried!

I had an awful experience- this supplement made me extremely sick. I took 2 pills 8:30am with toast - 30 mins later explosive diarrhea. Shortly after that vomiting started and that continued on and off all day. I couldn’t work all I could do was lay in bed sick and nauseated. Attempted to drink some ginger ale around 7pm that night immediately made me throw up again. Will be throwing this away and never trying again - wasted my day - extremely upset at myself for taking this supplement without researching further. There are plenty of negative reviews I should have read before trying.

Alpha Brain Boost

[This review was collected as part of a promotion.] I’ve been testing it out a bit, and it’s pretty neat. The 30-capsule bottle is a daily cognitive supplement aimed at boosting focus, memory, and reaction time. I’ve noticed it helps me stay focused during work, especially on sluggish afternoons. No caffeine jitters, which is great since I’m sensitive to that. Memory feels a tad sharper, like recalling meeting details easier. Reaction time’s tricky to judge, but I feel more alert. Pills are easy to take, and the packaging looks nice. Worth a try if you can get it!

Great stuff for focusing

[This review was collected as part of a promotion.] Great ingredients and can’t wait to see how it helps with my memory but it has definitely helped with focusing already. It doesn’t have any taste or anything. The packaging is sealed well and I can’t wait to see if it does exactly what it says and helps me with my memory and to mentally focus more which is has helped with already. Great value overall and happy I was chosen to be apart of this campaign.

Great product, helps me stay focused

[This review was collected as part of a promotion.] Great product! I wish it came with more since you have to take 2 a day. I noticed a difference within a week of taking the meds. I felt like I was more focused and aware. I plan to continue taking these to see if I see a significant difference after a few months
