It’s good

I can recall information more easily, and I feel more mentally clear and alert. The supplement has also helped me stay focused during long work hours.

Probably not my first pick

[This review was collected as part of a promotion.] I think this is pretty spendy for what it is. It didn’t really taste like any thing. You probably have to take this for a long time to see a difference you probably would have to do extensive research on the product to understand the ingredients. The packaging is nice.

Alpha brain vitamin support

[This review was collected as part of a promotion.] These brain vitamins I call them work. they help you focus, they give you entry throughout the day. I feel better taking these than drinking a redbull through the day. They also help you think clear with memory focus. these vitamins actually do the trick. I recommend trying these to enhance your memory and gain focus.

More Research Needed

I'd like to see an additional study done with alpha brain regarding the body's adaptation to taking it. The ingredients do what Onnit claims they do, and that is backed up by clinical research. However, I would like to see a study completed in which baseline levels (prior to alpha brain usage) of cognitive function are measured, then alpha brain is implemented just as it was in the pilot study, but then discontinue use of alpha brain and measure cognitive effects the following week, month, and year. A comparison of these performances would provide valuable information about how your body adjusts to the stimulus of Alpha brain, particularly Huperzia serrata in the long term, as it has been suggested that your body down-regulates its natural production of acetylcholine in response to prolonged usage if Huperzia serrata. If this is the case, regardless of how many precursors the body is supplied with, your cognitive performance will (theoretically) return to baseline while still taking the product and potentially drop below the original baseline level of cognitive function if the product is withdrawn (similar to anabolic steroid users who quit using steroids and experience a rebound drop in testosterone). I believe this research would prove valuable to customers and enable them make a more informed decision.

Sharp Focus Without the Jitters!

[This review was collected as part of a promotion.] I’ve been using Alpha Brain for a few weeks now and have noticed a real improvement in my ability to focus, especially during long work sessions or when I need to stay mentally sharp. What I love most is that it doesn’t give me the jittery feeling that other nootropics or caffeinated products can cause. It feels more like a smooth, natural boost. I’ve also noticed a slight improvement in memory and reaction time, particularly when multitasking. The fact that it’s stimulant-free is a big plus for me. I take it in the morning with breakfast, and it kicks in gently within an hour. My only reason for giving 4 instead of 5 stars is the price—it’s a bit on the higher end for just 30 capsules, and I wish it came with a larger quantity for better value. Still, it’s a solid supplement if you’re looking for daily cognitive support!

No more mental fog!

[This review was collected as part of a promotion.] This is a great supplement for anyone needing an energy boost! Taking care of a toddler is no joke, and I was relying on caffeine! These are caffeine free, with great ingredients, and no bad taste. No more mental fog! Try some today!

Keeps you sharp and focused without the jitters—pe

[This review was collected as part of a promotion.] Onnit Alpha Brain is a solid brain-boosting supplement that helps with focus, mental clarity, and memory. You don’t get the jittery feeling like with caffeine, but you still feel more alert and sharp. It’s especially handy during long workdays or when you need to stay locked in. Results vary, but for many people, it really does give your brain a nice edge.
