Made me nauseous

[This review was collected as part of a promotion.] I was given Aloha Brain by Onnit for free from #influenster in exchange for my honest review. I like that the product is caffeine and gluten free. I followed the daily recommended dosage and it made me nauseous. I can not confirm if the product did or did not enhance memory as I was consumed with a side effect of nausea. Maybe if I cut the dosage in half I would have had better results.

Like to see more studying

[This review was collected as part of a promotion.] ONNIT Alpha Brain Supplement I have taken this for the past two weeks and really can’t say I’ve felt any different. Of course, I will continue to take and test out, but no real changes thus far. I will say, I am the perfect candidate, as I am currently in my last semester of school and need all of the focus I can get. 👩🏼‍⚕️ 🩺 Would love to see additional studies from this brand as well.

to improve your memory and have more focus on your projects

[This review was collected as part of a promotion.] I gave it as a gift to my husband so he could try it. He really likes this brand. He needed something because he felt tired at work, couldn't stay focused on projects and forgot things easily. He said that the supplement helped him to be more focused, his memory improved and his mood is also better. He feels more willing to focus on his projects. This supplement has a good price and practical packaging to take anywhere. We recommend the product.

It’s alright

[This review was collected as part of a promotion.] First time trying a supplement to support memory and focus. It is interesting to see how a supplement can promote concentration and mental processing. I look up the ingredients and found, as claimed, that this supplement includes L-Tyrosine-known to promote calm and focused state, L-Tyrosine-promotes alertness and motivation, and Phosphatidylserine-support memory, stress relief and ability to focus. The list continues on with more ingredients that you can look up for your own research. I generally have issues with focusing as I tend to get distracted and work on something else. Overall, i recognize that my level of focus has somewhat improved while working. However, I think these type of supplements still need more study and research to evaluate and measure their true effectiveness.

Try it!

I can tell a big difference in my productivity after I take it in the morning. I can pivot from one thing to the other and keep going. I haven't really experienced that possibility in my daily life up till this point. Can't speak for everyone else, but it's definitely worth trying.

Not exactly what I was hoping for.

[This review was collected as part of a promotion.] I was super excited to try this out; but unfortunately it didn't deliver the results I was hoping for. The only thing I really noticed a change in was I felt a little more alert. But not moreso than intaking caffeine without the jitters. It absolutely could be that this just doesn't work for everyone; because it unfortunately did not work for me.

Kinda work

[This review was collected as part of a promotion.] I have been using this Alpha Brain Daily Cognitive Support for 2 weeks now and slightly feel the difference. The Nootropics really work. Being multi tasks, this helps with my focus. I am sleeping better.

Can't wait to try them.

[This review was collected as part of a promotion.] I haven't got to try them yet but hopefully they work. It did take a while to get here but finally got them. I hope they do exactly what they are suppose to. Packing was great was not damaged. The quality was great, along side of the value for money as well. Haven't got to taste yet.

Helps focus but restless sleeps

[This review was collected as part of a promotion.] I’ve been taking Alpha Brain for about 30 days now. I do feel like I’ve been able to focus better which is good but I have also noticed I have a much harder time falling asleep at night. Usually I’m in bed no later than 10pm and this past month I’ve not been able to fall asleep until 1am. Nothing else has changed in my diet and I’ve been taking this in the AM so I’m not sure if it’s Alpha Brain causing this or just something else. I’m not under and unusual stress so I know it’s not that. I’ll say if you struggle with focusing this does help but if my sleeping issues lately are due to this I probably wouldn’t suggest it. I won’t know for sure is the sleeping issues is due to this until probably a few days. I took my last one today.
