It didn’t work for me

[This review was collected as part of a promotion.] Unfortunately, it didn’t work for me. It caused me nausea. It’s a pretty big pill and I read ingredients prior to taking. I didn’t feel any different and the kind of nausea it caused won’t let me take it again.

Helps me stay more alert

[This review was collected as part of a promotion.] I've been taking this daily in the morning along with my multivitamin. It has vitamin B6 and L-theanine and other ingredients known to support focus and memory. I have been taking these for a few weeks now and I feel like I am more alert at work. I recommend giving these a try!

Tore my stomach up

[This review was collected as part of a promotion.] This made me so sick. I took it with a protein bar cause it said take with a light breakfast and it was bad. Made me throw up and nauseous. I do not recommend. Everything I ate that day went right through me too. Do not recommend.

🧠

[This review was collected as part of a promotion.] I received this product from Influenster in exchange for my honest review. I pills themselves are you typical material and size, taste was about the same as any other vitamin pill you might take. I like how clean these ingredients were and felt that it did improve my focus

Good so far

[This review was collected as part of a promotion.] It’s only been a short time of me taking these, so I can’t fully speak to their effectiveness. However, I take creatine from this same brand and really like it. I have high hopes for this product - more soon 🥳

Effective for Focus and Mental Clarity

[This review was collected as part of a promotion.] I’ve been using Onnit Alpha BRAIN for a few weeks now, and I’m genuinely impressed by the results. I noticed improved mental clarity and focus throughout the day, especially during work or when trying to stay on task. It didn’t make me feel jittery like some other supplements — it’s a clean and smooth mental boost. I also appreciate that it uses natural ingredients and is caffeine-free, which makes it great for those who are sensitive to stimulants. It worked best for me when taken consistently, so I’d recommend giving it a full week or two to really feel the effects. Perfect for anyone needing help with concentration, memory, or mental energy — especially students or professionals. I’d definitely buy it again!

Pretty helpful

[This review was collected as part of a promotion.] So far, this feels effective. The taste isn't too bad, and the ingredients are great. It has a vegetarian capsule, so it could appeal to those who do not use meat based products.the label gives all the info needed. So far, I like them !

Just kinda ehh

[This review was collected as part of a promotion.] I'm not sure that this memory and focus supplement did anything at all. I definitely didn't notice any spectacular results. There weren't any adverse effects of taking it either though. Just kinda ehh

You may not notice a difference right away

You will need to take these for at least a week for this to work. After my first week, I did not think it helped much. Then I decided to skip a day. It was certainly noticeable that whole day. I work from home and found myself easily distracted, tired, and not motivated to accomplish much. I resumed taking them again the next day and have been a fan ever since. I get far more accomplished in less time than before.

Subtle Boost — Still Unsure About Long-Term Effect

[This review was collected as part of a promotion.] Tried Alpha Brain for a couple of weeks — not a dramatic change, but I do feel a bit more focused, especially in the morning. No side effects so far, which is a big plus. I’m not sure yet if it’s worth the price long-term, but it’s a nice little boost for now.
