Keeps my mind sharp

[This review was collected as part of a promotion.] Not only do I like the fact that the capsules are vegetarian but I like that they don't have an off putting taste or smell like some supplements do and they're super effective to the point that I found myself more focused and attentive and remembering a little bit more than usual

Good product!

[This review was collected as part of a promotion.] I recently tried Onnit Alpha BRAIN, and overall, it's a pretty remarkable supplement. It's designed to support cognitive function, and I noticed some improvements in my focus and mental clarity. However, I did experience some side effects that were a bit off-putting. While the benefits were evident, it's important to be mindful of how your body reacts. Despite this, for those looking to boost their brain power, Onnit Alpha BRAIN is still a solid option. Just be sure to consider and monitor any adverse effects. I would recommend trying it to see how it works for you.

Amazing for focus & clarity!

[This review was collected as part of a promotion.] Alpha Brain is awesome! I noticed a big improvement in focus and mental clarity within a few days. No jitters or crashes, just steady, clear thinking. Perfect for busy days when I need to stay sharp. Definitely recommend!

Worth a shot

[This review was collected as part of a promotion.] Packaging is simple, which I don't mind. It does seem to work, I didn't research the ingredients too much, but I felt fine taking them. I did take less than what it said to. Otherwise, I felt a little nauseous. Price is a little much, but it's worth it in the end if it works for you. It also doesn't have a taste, which is a big plus, I hate taking pills that leave a nasty taste in your mouth.

Great ingredients with caffeine

[This review was collected as part of a promotion.] I love me a brain supplement as i tend to forget so much and feel my mind set carry to much to elevate my brain and get things done. I love the natural herbal supplements capsules, i feel they are more effective than compressed pills. I love that it has caffeine and helps you focus and helps with memory. The ingredients are great it contains vitamins B6, L-tyrosine, L-theanine and other great ingredients to be effective.

Onnit alpha brain

[This review was collected as part of a promotion.] Received this Onnit Alpha brain supplement to try out complimentary of influenster. Bottle only comes with 30 capsules and directions are take 2 daily. That means I only used for 15 days and really not enough to see it truly works, unfortunately. Did not have any bad side effects, easy to swallow, no after taste. Would have needed to try out for at least 2 to 3 months sadly not enough product.

Who knows!

[This review was collected as part of a promotion.] On paper, these sound amazing but I just don’t think a single bottle holding 30 capsules at 2xday is enough for me to be able to make a statement as to their efficacy. What I CAN say is that the capsules are easy to swallow and don’t leave an aftertaste. Since they’re caffeine free, you don’t have to worry about any jitters nor do you have to change your normal caffeine intake which is always a win in my book. Did I suddenly have laser focus when tackling projects? Nooo. Did I manage to remember my parents’ anniversary day for a change? Also no. So take it with a grain of salt (or a pinch or two of it) and proceed at your own risk!

This one really works for me

[This review was collected as part of a promotion.] I've been taking these for a few weeks now and can really feel and see a difference. I'm more alert I can see to get things accomplished better I'm sleeping a full night and I'm not so lost feeling all the time. There's no nasty taste to this and no crazy side affects so I would recommend it to anyone whose on the fence about trying it out.

Memory enhancer

[This review was collected as part of a promotion.] This stuff seems to make me able to focus more than usual and my memory is improving. I've been using it for a month, now. No bad taste. I'm thinking I'll buy some more to see how I feel after 2 months!

Not worth the price

When I first started using alpha brain I did feel like I noticed an increase in focus and short term memory but after a few weeks i noticed no difference in days i took it vs days i dont and after a few days of non use felt like i had harder times focusing than i did before i started using the product. Could all be placebo could work but my body builds a tolerance. Not sure but I have canceled my monthly subscription because to me it dosnt seem worth it. Just my opinion

reply from Customer Experience

Hi Pat, Thanks for your feedback! Sorry to hear about your experience with Alpha Brain. Sometimes the body needs a break from supplementation. In theses cases, we recommend taking a week off to let your body reset. After a full seven days without Alpha Brain, try taking it again to see if that helps! Again, thanks for your feedback and #StayOnnit!
