Unfortunately not for me

[This review was collected as part of a promotion.] I was very excited to try these however I feel a little queasy taking these. I would advise to take with a meal. They are supposed to make you alert and help with brain functions. I do feel alert however i dont tend to like supplements that make my heart race. Not for me.

Nice!

[This review was collected as part of a promotion.] These onnit Alpha Brain supplements come in some pretty slick packaging. They’re easy to take and don’t have a nasty after taste. They’re easy don’t smell. Overall pleased with the product. Waiting to see if they help with “mom brain”

OMG, ruined me!!

Day 1, about 4 hours after I took my first dose with a light meal, i was hit with horrible nausea, thought i was gonna hurl, and i was at work!! then came the worst gas ever...by the time i made it home, my body totally purged itself from the back end for like 2 hours. i thought i had food poisoning, didn't connect it with AB...by the time I went to bed & the next morning I felt great. Day 2, exactly the same thing happened, so i figured it was AB, and after reading lots of reviews, i see that it was. Didn't take it for 2 days, felt fine. Took it again just to make sure, WHAM, exactly the same symptoms. This is not worth it, especially for the $$. And my diet is pristine, i'm very healthy for my age, am a regular at crossfit, have never had a reaction to any supplement...i canceled my trial, will not be purchasing any more stuff. but i love Joe Rogan (heard about it on his podcast)

Alpha BRAIN® helps me stay on top of everything, e

[This review was collected as part of a promotion.] As a busy mom, staying focused can be a challenge – especially with toys everywhere and kids running around 😅 Alpha BRAIN® has been a game changer! I love that it’s caffeine-free but still helps me stay sharp, clear, and productive throughout the day. Definitely adding this to my daily routine!

Use alpha brain to focus at home and work

[This review was collected as part of a promotion.] Wow alpha brain really does clear up my perimenopause fog! I find i can focus longer on my computer and doing tasks around the house in the morning. Its easy to swallow 2 pills per day to see results within a week.

Avoid this

[This review was collected as part of a promotion.] This product is honestly not very good, I think this is a reach to clean up past reviews and even a lawsuit claiming it doesn’t work. Which I would have to agree with. Someone else I shared with got a headache and 0 benefits that it claims.

Thanks for taking the time to share your experience! We're sorry to hear that Alpha Brain wasn't the right fit for you. It's expected that we have a range of responses since supplementation is not one size fits all. Sometimes it can take a few tries to notice these effects. Experimentation is key! That being said, we would never want you to feel stuck with a product that didn't meet your expectations, and if you reach out to our Customer Service team, they'd be happy to help further!

Mental Focus On Point

[This review was collected as part of a promotion.] I've been using Onnit Alpha Brain for a few years now along with my husband, and when I take it I always notice a real improvement in my focus and mental clarity. It helps me stay sharp during work and feel more mentally organized throughout the day. I also like that it's made with natural ingredients and doesn't give me any jittery side effects like some other supplements. The packaging is simple but attractive to both men and women. They are fairly tasteless in my opinion. Overall, it’s been a helpful addition to my daily routine, and I’d recommend it to anyone looking for a little cognitive boost.

Here’s my take

[This review was collected as part of a promotion.] Key Ingredients: 1. **L-Theanine & L-Tyrosine**: These amino acids are known to help with relaxation and stress reduction, while promoting focus and mental clarity. 2. **Alpha-GPC**: A source of choline, a compound that supports brain health, cognition, and memory. 3. **Huperzine A**: Derived from a plant, this ingredient is believed to help with memory retention by inhibiting the breakdown of acetylcholine, a neurotransmitter involved in learning. 4. **Bacopa Monnieri**: An herb traditionally used to enhance memory and cognition over time. 5. **Oat Straw**: Known for its potential to support mental clarity and reduce stress. ### Effectiveness: **Pros:** * Many users report an increase in mental clarity, focus, and memory after taking Alpha Brain, particularly for short-term tasks and productivity. * The combination of ingredients works well for cognitive enhancement without the jittery side effects often associated with stimulants like caffeine. * It's well-suited for people who need to be alert and clear-headed, whether at work, studying, or engaging in creative projects. **Cons:** * Some users may experience mild side effects like headaches or digestive issues, especially if taken in high doses. * It takes time to feel the effects — you may need to take it consistently for a couple of weeks before noticing a significant improvement in cognitive function. * Price could be a downside for some, as it’s on the higher end compared to other nootropic supplements. ### Final Thoughts: Alpha Brain has earned a solid reputation in the nootropic world due to its combination of well-researched ingredients and lack of strong stimulants. While the benefits are more noticeable with long-term use, it can certainly help improve focus and mental clarity for those seeking cognitive support. If you're looking for a supplement that delivers gradual, sustained cognitive benefits without overstimulating your system, Alpha Brain could be a good fit. However, if you’re on a budget or looking for faster results, you might want to explore other options.

Sharper Focus and Clarity

[This review was collected as part of a promotion.] ONNIT Alpha Brain supplements deliver on their promise. I'm impressed by the high ingredient quality, clearly listed and natural. While there's no taste as it's a capsule, the sleek, professional packaging is great. I find the value excellent given the noticeable cognitive boost. It truly enhances focus and mental clarity. A highly effective supplement for daily mental performance!

Helps your focus and memory!

[This review was collected as part of a promotion.] These brain supplements are great for daily intake. You will notice a real boost in focus, memory, and mental clarity. They help me stay sharp and productive without the crash. Bottle comes in a 30 day supply and they’re capsules, so no nasty vitamin taste. Great for work or study!
