[This review was collected as part of a promotion.] I definitely notice improved focus and mental clarity, especially during busy workdays or study sessions. It doesn’t make me jittery like coffee, which I really appreciate. The capsules are easy to take, and I like that it’s made with natural ingredients. That said, the effects aren’t super dramatic—it’s more like a subtle sharpening of focus. Price is a bit high, but if you’re looking for a clean mental boost without stimulants, it’s worth a try!

My honest opinion

[This review was collected as part of a promotion.] I received this product for free from Alpha Brain and Influenster for my honest opinion. Think this product can be effective if taken daily for me I was not actually using it like recommended to receive the full effect. The taste is not bad and I feel that it is a good quality and cost. The packaging is nice and th3 black stands out to me.

"30 count" is 2 a day, so just 15 days worth...

I just got the bottle in the mail yesterday and I realized that it says serving is 2 pills A-day. So they say 3rd account on the website right and you've just assumed with common sense that that's 30 days worth one month of supply, Which is what most pills and supplements are; a 30 day bottle. This product came in a tiny bottle with 30 count but the bottle was less than half full. I went to all of my other supplements that I take for everything else and they are all at least overhalf whole when you get them. This is incredibly frustrating as and as a first time customer I feel like I'm being tricked, I think this is A gimmick and a scam to get you to give up your money. It would be a different story if they said it was a 15 day supply or a 30 day supply, but instead they say 30 count or 60 count. Too many companies spend time and effort to trick and mislead their own customers. I find this a huge turn off. Also I'm not sure how you could even evaluate a product in 15 days to decide whether or not you want to keep giving them your money... My intuition is telling me that there is no magic pill for anything in this world at all. This is no exception. Otherwise the bottle wouldn't be LESS than half full with a 30ct that last only 15 DAYS!!....

Thanks for taking the time to give us this feedback, and we'd be happy to provide some insight here! Alpha Brain comes in two sizes, 30ct and 90ct. The supplement facts on the product page shows a suggested max daily serving of 2 capsules. However, since everyone will respond differently to this product, not everyone will need to take 2 capsules to feel the benefits. Alpha Brain doesn't have to be taken everyday, and can simply be taken on an as-needed basis when you need a little extra boost in focus! Two weeks is about the general time frame to start feeling any benefits, if being taken daily. That being said, if you still aren't feeling it after 2 weeks of regular use, let us know! We're happy to help with some supplement tips and/or to help facilitate a return if needed. You can email help@onnit.com for further assistance with your order!

Good stuff

[This review was collected as part of a promotion.] This is a product to help with memory. It’s a mix of vitamins in a typical vitamin packaging which is nice. Swallow right away for no taste. I would say this is definitely giving the vitamins needed but you can’t get missed memories back so don’t be confused!

Interesting product! Need more research data!

[This review was collected as part of a promotion.] I received OnnitAlpha Brain from Influenster for free in exchange for an honest review. This nootropic formula is designed to support memory, focus, and mental clarity, and has sold over 7.5 million bottles, which speaks to its popularity. The formula is caffeine-free, making it suitable for those who are sensitive to stimulants or prefer to avoid caffeine altogether. Alpha Brain promotes the production of alpha brain waves and supports the levels of the neurotransmitter acetylcholine, which are both essential for cognitive function. However, despite the promising claims and the positive feedback from others, my experience with Alpha Brain has been less remarkable. I haven’t noticed any significant changes in my cognitive performance. The capsules are small and can swallow easily. Research on Alpha Brain, including a double-blind, placebo-controlled study, suggests that it may enhance verbal memory and executive function in healthy adults. While these results are encouraging, it's important to note that individual responses to nootropic supplements can vary. The results experienced by others may not be the same for everyone. Additionally, more research is needed to fully understand the long-term effects and overall efficacy of Alpha Brain. Given this, while Alpha Brain appears to be a promising product, I’m hesitant to recommend it at this time. It’s worth considering, but I believe more research data is necessary to better understand its impact, particularly over the long term.

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!

NAUSEA, HEADACHE AND VOMIT

First day Took two capsules with coffee and ritz crackers, started feeling nauseous after 30 min or so and mild headache started and it got worse. Vomited on third hour, felt like my gut was about to come out. Second day, took two after lunch. Started feeling nauseas after 30 min, had headache all day. Third day, didn't take any but still have nauseas feeling. Threw it in the trash. Not for me. Label says to try it at least 2 weeks. NOPE.

Game changer

[This review was collected as part of a promotion.] I have found Alpha Brain to be amazing and truly allows me to perform to my full potential, primarily at work where I’m required to multi-task between a variety of departments. I shift gears throughout the day and require almost total recall of facts and figures, and having just turned 65, AB makes a huge difference. Seems to only take about 2-3 days to kick in. My son uses it now and it has changed his life for the better. Please don’t forget to eat something first!!

Mental clarity and on point focus

Trying this product after listening to the JRE i wont go back. Feeling so stable and on point from taking these tablets in the morning. In combination with upping the dosing of Omega 3 and Vitamin D from listening to JR and Dr. Rhonda Patrick. You guys are the best for information coming from Australia these tablets are really expensive compared to pretty much every other supplement so thats why it isnt a 5 star review. Getting this product onto Australian shelves and 1/2 the price would be ideal

Not sure it does anything

[This review was collected as part of a promotion.] So I started by taking the recommended dosage and felt nauseous for hours. I tried again a few days later with half a dose and felt fine. Easy to use if you can swallow pills and has no taste. Not sure if I noticed any real difference in my cognitive abilities but will continue to use until the bottle is out just in case.
