Foucus 🧠

[This review was collected as part of a promotion.] I got this awesome complementary Alpha BRAIN by Onnit. I started taking alpha brain and to my surprise it actually does work. Aside from the flavor it doesnt give me any jitters. I started noticing a difference the first week. My attitude and mental health improve, enough to lower my stress at work. Thoughts were a bit clearer and my focus was a tad sharper. Although the price is a bit up there i do not mind taking it again.

Improved focus

[This review was collected as part of a promotion.] I have been trying the Alpha Brain suppleme ts for a little over a week now. I do feel more focused with better energy. The ingredients are high quality, and there is very little taste. I will definitely continue using this product and update again further down the road.

Average

[This review was collected as part of a promotion.] Easy to read instructions. Pills were a bit large but didn’t affect taking. I didn’t notice a difference until the second week in. Just a bit more clarity my overall feeling changed I definitely had more clarity. I wouldn’t purchase again because the price point for the amount you get wasn’t for me. Packaging was great it gives all info in detail. Taste was ok I didn’t have an after taste come up so that’s a plus.

Nice presentation, but mild results

[This review was collected as part of a promotion.] I took it daily for 2 weeks, following the instructions. Unfortunately, I didn’t notice any improvement in focus, memory, or mental clarity — it honestly felt like I wasn’t taking anything at all. On the plus side, I had no side effects, and the capsules were easy to swallow. There was no unpleasant taste or aftertaste, and the smell was mild, which I appreciate. The packaging looks premium and well-designed, adding to the initial appeal. That said, the retail price feels too high considering the lack of noticeable effects. I was also unsure about the inclusion of cat’s claw — a traditional herbal extract that lacks strong scientific evidence for cognitive support. I appreciate the clean formula and good tolerability, but it simply didn’t work for me. Might be helpful for others, but I didn’t experience any noticeable results.

Focus and memory capsules

[This review was collected as part of a promotion.] Well I have only 2 weeks trying these capsules and so far I can say that if it has helped me to focus since lately I have been very distracted and if I have noticed that it helps me to focus more. for me I feel that if they are a little difficult to swallow but with enough water they pass, the price for what I have seen so far seems good to me I will continue taking them and see what more benefits they bring me

Onnit Alpha Brain

[This review was collected as part of a promotion.] I’ve been using Onnit Alpha Brain for a few weeks and have noticed a slight improvement in my focus and mental clarity, especially during work and reading. I like that it’s caffeine-free, so I don’t get jittery, and it’s easy to incorporate into my routine. That said, the effects aren’t dramatic, and results seem to vary from person to person. It’s worth trying if you’re looking for a mild cognitive boost, but manage your expectations.

Horribly SICK

I took two just before work at 3am. I drive a Ed garbage truck. I got to work and took off in my truck when I started to feel sick in my stomach. Ten minutes later I was puking in my lunch bucket. I headed back to the yard and tried to drive home but had to pull over several times due to the overwhelming feeling of almost passing out. I could have gotten a DUI according to the laws in Oregon. I was so sick and so tired I could barely walk and when I got home I went straight to bed and didn't wake up until 7 pm. I do not recommend this to anyone. It's a gamble not worth it.

Good

[This review was collected as part of a promotion.] I got this supplement from this app for free so I am not sure its price. I gave it to my dad and he said it helped him a lot. Yeah, he takes it around 10 days and stops it in 2 weeks then repeats the routine.
