Thank you for giving me my life back..!!!

I've been in a slump for I'd say yrs. No drive, no energy,no anything. My life was just living in a daze all the time. I didn't want to do anything, go anywhere. After I started Alfha Brain, my while world changed. I found myself out of the house out in the garage working on my car doing the things I used to live. I feel sharper,mentally faster, just zoned in. It saved my life. I'm actually enjoying life again. Thank you Joe Rogan for giving me my life back..!!!

Impressive

This product is awesome. I was highly skeptical about it, but after the first dose of two capsules, I was very focused. Other stimulant focus supplements / beverages/ medicine give you a weird rush, hyperventalitve feeling that makes you feel awful. Alpha brain gave me a very focused mind state without feeling jittery. Beware to take witth a small snaxk or meal because it will give you a slight mental rush, but nothing as crazy as adderrall or red bull. The food just helps you keep securely grounded. I think this is the best nootropic out there because it's all natural and I have yet to hear raving reviews about a similar product. Lastly, my memory has improved tremendously; I'm able to finish my work faster without it and it makes my brain feel healthy. My brain somehow feels very strong and firm and gives me a strong push with anything I do. I have to thank The joe rogan experience because he always has good things to say about it during his podcasts and if anyone reading this is considering to buy this product, do it, you won't regret it.

Good stuff

[This review was collected as part of a promotion.] I like this supplement, but it seems like I have to be careful when I take them. If I take them late in the day I can’t fall asleep, guess my brain is working better then! 🤣🤣 I do feel like these help!

Improves memory and cognitive function!

[This review was collected as part of a promotion.] Have you tried Alpha Brain supplements yet? I had the pleasure of trying the famous Joe Rogan supplement for memory improvement and sharpness! Thanks to Influenster for sending me Onnit Alpha Brains supplements for free in exchange for my honest review. It’s one of the most effective supplements for cognitive performance. It supports memory, promotes focus mental processing and flow state. It’s caffeine and gluten free. I really saw improvement especially being a busy mom who is exhausted a lot. It keeps you alert and focused. To be honest I felt sharp and awake like when I drink my morning cup of coffee! I will keep trying it out and see if any changes occur!

it felt like a mild boost in focus and alertness,

[This review was collected as part of a promotion.] I tried Onnit Alpha Brain supplements after reading about their benefits. The product contains amino acids that support the release of dopamine and serotonin in the brain, which can help with focus and mental clarity. After taking it, I noticed a difference within about 15–20 minutes it felt like a mild boost in focus and alertness, making it easier to stay productive and engaged throughout the day. I liked that it didn’t make me feel jittery, just more sharp and centered. It’s an excellent option for anyone looking for a natural way to support brain function and maintain focus. I’ll definitely continue using it as part of my daily routine for mental clarity and productivity

No difference noted

[This review was collected as part of a promotion.] The packaging was normal and in a dark bottle to keep from sun damage. There was no taste which was good. The quality of the ingredients appeared to be of higher quality. While taking, I did not notice any difference which is why I won’t be continuing with this product.

Focoused and Clear

[This review was collected as part of a promotion.] I tried Onnit Alpha Brain because I wanted something to help with focus and memory, especially on busy days. Right away, I liked that it doesn’t have caffeine, so there’s no worry about feeling jittery or crashing later. After using it for a bit, I noticed I was able to stay more mentally “on” and focused, particularly when I had to juggle a lot of tasks or stay creative. The ingredients list is interesting that are meant to support brain health in a more natural way. For me, it gave a subtle but noticeable boost in clarity without feeling overstimulated. It’s not like a magic pill, but for days when I need to feel more mentally sharp, Alpha Brain has been a great addition. It’s worth trying if you’re

Caused loss of ability to speak and motor function

About an hour after I took the two capsules (as instructed by Onnit), I thought I needed to go to the hospital. I was trying to articulate something to my husband, and I could barely form a sentence (beyond frightening all on its own). Shortly after, muscles all over my body started to periodically twitch to the point where I needed to lay down in fetal position. When I tried to stand and walk, the effort felt enormous and I was afraid I would collapse. I eventually also experienced nausea. In a panic I researched reviews on the product and found many on various websites that said they experienced the same thing and that it will eventually subside, which is the only reason I didn't make my husband drive me to the ER. Instead of having the productive day I expected, I spent it trying to sleep it off. I'm not going to knock brain supplements because most are excellent, but the particular blend in Alpha Brain is extremely dangerous. If it were only myself that had this experience, I wouldn't say this, but the amount of people who are saying they had the same reaction is unacceptable. I do NOT recommend this product- what happened to me and many others is not normal, it's disabling and unsafe.
