Bad Nausea

After a few hours after taking I had terrible nausea. I had to lay in bed the rest of the day and it didn’t go away until the next day. I took two capsules with a light meal, as directed…This was my first time trying and unfortunately I’m definitely not ever taking this again.

Supplement

[This review was collected as part of a promotion.] This supplement works wonders for my husband. It helps him focus on work without getting too distracted. I love that it's made with natural ingredients and the capsules are Tasteless. So far, it has no unusual side effects. Alpha Brain gives you better focus and more mental energy. This bottle has 30 units and is for men and women. It's designed for brain health. Its purpose is to help with mental agility and concentration. To see health improvements with supplements, you have to be consistent..

Cognitive support supplement by Onnit

[This review was collected as part of a promotion.] After a week of consistent use, here’s what stood out: ✔ No digestive issues – Easy to take with my morning meal. ✔ Vegetarian, gluten-free & caffeine-free – No jitters or crashes! ✔ Enhanced focus & productivity – I noticed an improvement in my ability to stay on task. ✔ Great for students & professionals – If you need a mental boost, this could be worth considering! I also liked the amber bottle design—a nice balance of function and aesthetics. Would I use this again? Yes!

A vitamin to help with brain focus

[This review was collected as part of a promotion.] I really liked the packaging and the taste was not bad. I did like that it had a lot of vitamins in it to help with brain focus. Unfortunately for me and it might not be for everybody but it made me very sick. I am not sure what was in it for me to be so sick to my stomach and it could have been too strong for me. I wish I could have kept taking it but I could not. I hope everyone else had positive results

Good but can make you dizzy

[This review was collected as part of a promotion.] So far I think it’s helped me with my focus but be warned you have to have a light meal with this. this made me a little dizzy because I didn’t have too much to eat and took with my regular supplements in the morning. Packaging is economical but not sure if I would spend full retail price on this supplement. 7:10 for me.

Truly gives you more focus!

[This review was collected as part of a promotion.] The Onnit Alpha Brain works so well! It is super effective and truly helps me feel more alert. The ingredient quality is healthy and there is a mild taste from the capsule. The packaging makes it easy to use and safe from children. Truly worth the money!

A product that's supposed to boost memory. The ing

[This review was collected as part of a promotion.] A product that's supposed to boost memory. The ingredients are high-quality, and the capsules are a normal size. I hope to benefit from it, even though I haven't had many effects so far. But that may still come. The taste is neutral.

Definitely notice a difference

I definitely notice a difference when my husband takes this every day as he gets a lot more done and his in a better mood. The only reason I give it for starters is because I haven’t heavily research the ingredients to know what long-term effects are. Also when he does not take it his motivation level goes back down again so unfortunately it’s probably not fixing the problem
