Quicker reactions and more alert - they work!

[This review was collected as part of a promotion.] I was a little weary of trying a new supplement, as I have a handful of ones I take already. I was pleasantly surprised to feel more energetic and aware after taking these. I even felt like my reaction time on the volleyball court was a bit quicker. I had seen many ads saying how great these are - so I’m glad I got to try them. I will keep using them for a few more months, especially as I go back to school for more masters credits. I would recommend trying these to see if they work for you too!

Effective & Help with clarity and focus

[This review was collected as part of a promotion.] These capsules have really helped me with my focus and clarity. I feel more clear-headed since taking them and am able to zero in on tasks and listen more effectively in conversations as well. I do wish it was a longer supply, with 30 capsules only good for 15 days, but still a solid product with a good value for your money.

I like it!

[This review was collected as part of a promotion.] I tested them! The excellent composition and quality of the ingredients gave good results. They are effective. The taste is not unpleasant at all, and the size is convenient for drinking. Stylish and convenient packaging. And most importantly, good value for money.

👎🏽

[This review was collected as part of a promotion.] I had high hopes for Onnit Alpha Brain, but unfortunately, it didn’t work out for me. After just a few days of use, I started experiencing severe headaches and nausea, which only got worse the longer I took it. Instead of boosting my cognitive function as advertised, it left me feeling drained and on edge. I tried reducing the dosage, but the side effects persisted. For the price and the promises, I expected much better results. Sadly, this supplement did more harm than good for me. Would not recommend.

Works!

[This review was collected as part of a promotion.] Ok! When I first started this product, I was skeptical but it is actually effective! Packing is great and I like the natural ingredients too. No taste and great value in my opinion. I feel more alert.

The Only supplement that improve focus and Mental

[This review was collected as part of a promotion.] I've been using rhis Alpha Brain supplement for a few weeks now, and I’ve noticed a significant improvement in my focus, memory recall, and mental clarity throughout the day. I take it in the morning with breakfast, and within about 30–45 minutes, I feel more mentally organized and alert, like my thoughts are firing more smoothly. I also noticed better dream recall when I take it consistently. Of course, individual results may vary, but for me, Alpha Brain delivers on its promise of cognitive enhancement without the crash and I do not mind the tast of it. Highly recommended if you're looking for a clean, effective brain booster.

Easy to swallow and effective

[This review was collected as part of a promotion.] My husband and I both started taking one pill to try out. We noticed results on the same day. My husband shot an amazing score on the golf course. I accomplished the most I have in a day as far as doing house chores efficiently. It is easy to swallow and does not have a thick outer coating. There is no flavor or weird tasting burps. The packaging is convenient and easy to open.

Results vary. Read ingredients and effects.

[This review was collected as part of a promotion.] I tried Alpha Brain for better focus, energy, and overall well-being. The first day, I made sure to eat a good breakfast before taking the supplement. It does not have any flavor to the capsule. The bottle had a child safety lid to keep keep kids safe. I felt the effects fairly quickly. My energy was very high, and my focus was sharp. My stomach, however, didn't agree. The next day, I did not take a dose. I felt VERY tired and lethargic all day.

5 days in...

I have been on alpha brain for about 5 days now and this is what I've noticed... Before I started I was not one for remembering dreams and I now have very vivid dreams that I recall frequently. I wouldn't call them "lucid" but they are easier to recall and very specific. As far as increased focus and cognitive function I can't say that I've noticed a drastic change. I noticed more of a change in my focus when I was supplementing krill oil and an EPA extract but I did not have the dreams like I do with alpha brain. I bought the double pack so I will see where I am at in a couple weeks but for right now, placebo effect or not, I think the dreams alone are worth the purchase!

Alpha Brain Cost

[This review was collected as part of a promotion.] This was highly promoted by a big-time Podcaster, so imagine getting my hands on it for review. I was so hyped to see if this would assist with focus. In my time, I did notice I was more awake and attentive. This is a major plus in my area of work and greatly appreciated. I haven't noticed any bad symptoms, so that's a plus. Im highly sensitive to anything, so also another good note. However, for the dosage vs. little quantity for the cost, it is too high to keep up

Thanks for giving Alpha Brain a shot and for sharing your experience! Everyone's experience can be a bit different with a formula like this. It's formulated to help support memory, focus, and processing speed, and it can take some regular use to really feel these changes. We suggest trying it for at least two weeks and if you still aren’t happy we can help with some supplement tips and/or to help facilitate a return if needed.
