Highly recommend

[This review was collected as part of a promotion.] The capsules are odorless and very easy to take, which is great for those who are sensitive to smells. After about two weeks of use, I’ve noticed an improvement in my focus , I feel more productive and less easily distracted. I haven’t seen a big change in memory yet, but one unexpected benefit is that I’ve had fewer headaches. I think I’ll need to continue using it for a longer period to fully experience all its effects. I plan to keep taking it and see how it goes.

Always Important to take care of your noggin!

[This review was collected as part of a promotion.] I originally opted into trying this brain supplement from Onnit because I’ve been mixing up my words a lot like no auto correct mistakes 100% me so I thought it would help me. However, I’m still having mistakes so I’m thinking it’s not the best for me. But, it doesn’t smell or taste bad in my opinion. You do need to make sure you consult your doctor first before taking especially if you are on medications or have any health issues.

No noticed improvements

[This review was collected as part of a promotion.] I took Alpha Brain for 30 days and did not notice any improvements in my focus or mental clarity. It did seem to make me nauseous a handful of times but most commonly it gave me horrible gas. This product is definitely not a good pick for myself.

Noticeable Mental Boost Without the Jitters

[This review was collected as part of a promotion.] I’ve been using Onnit Alpha BRAIN® for a few weeks now, and I can genuinely feel a difference in my focus and mental clarity—especially during long work sessions or creative projects. It’s not like caffeine where you get a jolt of energy; it’s more of a smooth, steady mental sharpness that helps me stay on task without distractions. I really appreciate that it doesn’t make me feel jittery or wired, and there’s no crash later in the day. It’s also nice to know the formula is stimulant-free and made with natural ingredients. I’ve found it especially helpful before presentations or intense writing sessions. The only reason I’m giving it 4 stars instead of 5 is the price—it’s a bit on the higher side for a supplement. Also, while I noticed benefits, I’d say results can vary depending on your baseline energy/focus levels. Still, if you're looking for a nootropic that gives your brain a gentle push without harsh side effects, Alpha BRAIN® is definitely worth trying.

Did not make me feel nauseous

[This review was collected as part of a promotion.] Took the pill with my breakfast the last week. I am glad it didn’t make me feel nauseated like other multivitamin pills do in the market. It did not leave a bad taste in my mouth. I hope that continued use will help improve focus.

Effective

[This review was collected as part of a promotion.] I tried this supplement and was initially skeptical, but it ended up being effective for me - though not a dramatic improvement. With continued use, it helped my memory and focus. The capsules are easy to take, it is both caffeine and gluten free.

Inaccurate Ingredients

[This review was collected as part of a promotion.] I haven’t found any good ingredients in them and there is no exact dosage, it’s not specified exactly how much of each substance I read the reviews, there are pros and cons, but I didn’t drink it, I didn’t risk it and try it. That’s why I’ll skip it

Decent nootropic

[This review was collected as part of a promotion.] It gives me a boost of energy. I did not see any difference in clarity, maybe because it’s just 30 capsules and not enough to elicit that outcome. It came packaged in an amber bottle and has not taste to it.

Great supplement for daily cognitive support!

[This review was collected as part of a promotion.] I love this Onnit Alpha Brain memory and focus supplement. It's daily cognitive support that includes great ingredients like L-theanine and Vitamin B6. You only need 2 capsules per day, which makes it easy to take. It's also caffeine free!
