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!

Great

[This review was collected as part of a promotion.] I’ve been trying Onnit Alpha Brain for the past few weeks and have some positive impressions to share. First off, the packaging design is very sleek and professional. The dark tones combined with clean branding give it a premium and trustworthy look — it immediately feels like a product made for high-performance individuals. In terms of effectiveness, I started to notice a difference after about a week of use. My mind felt clearer, focus improved, and I was able to stay mentally sharp even during long hours of work. One thing I really appreciate is that the product supports memory and cognitive function without any noticeable jitters or crashes.

Alright

[This review was collected as part of a promotion.] Honestly, I did not notice a difference in cognition when using the supplements. Perhaps I just need to give it longer. There was only a 2 week supply in the bottle anyhow. I like the ingredients and how they combine herbs for both relaxation and focus. The supplements are a large capsule size, which made swallowing them hard sometimes. Not bad tasting good bang for your buck.

Dials You In

[This review was collected as part of a promotion.] I received this product from Influenster to review. I was skeptical about it and thought it would be a placebo but they’ve been working great. They are tasteless pills will all natural ingredients and I have been focused with all of my work and studies much more recently ever since I started taking the pills.

Not for me

[This review was collected as part of a promotion.] I was super excited to try this supplement as I struggle with both memory and focus. Sounds perfect, right? Unfortunately this had the opposite effect on me. This made me feel more confused and foggy. The capsule are rather large making them a bit difficult to swallow. I did give it 2 stars because it is well packaged and seems to be well formulated, just not for me.

Good for memory

[This review was collected as part of a promotion.] This is a great supplement if you struggle with memory and focus. I have my husband take it as he has been complaining lately that his memory isn’t as good as it used to. Serving size is 2 capsules and very easy to swallow.

The brain boost you need!

[This review was collected as part of a promotion.] I don’t know if it’s placebo or not, but I seem to get more things done after taking these supplements! I have to take them with food, otherwise they make me a bit nauseous. But they do appear to give me a boost in productivity.

Boosting Focus and Memory: A Week in the Life of a Busy Student and Mom

[This review was collected as part of a promotion.] As an IT student and a mother of a toddler, my days are filled with constant mental juggling. The cognitive load is intense—whether I’m remembering network ports, studying for exams, or keeping up with my little one’s energy levels. I decided to try Alpha Brain to see if it could help me manage everything a bit better. After just one week of taking the supplement, I can honestly say that while it hasn’t turned me into a superwoman, it has made a noticeable difference. I’m retaining more information during study sessions, and I’ve found it easier to stay focused on tasks until they’re completed—no small feat when you’re constantly being pulled in different directions. I researched every ingredient in Alpha Brain before starting it, and I was impressed by the science behind them. Each component is designed to strengthen brain function, and so far, I’ve felt the benefits. I would definitely recommend Alpha Brain to students, professionals, or anyone who needs to be at the top of their mental game.

Definitely gives more focus!

[This review was collected as part of a promotion.] I received this product as a sample to try in exchange for my honest review. First this product is super easy to take- its not a huge capsule so it goes down fairly easily. There is no taste which is a huge plus! I do feel more focused when i take it! All in all i believe this to be a good product and i will consider purchasing once my sample runs out!
