Didn’t notice too much of a difference personally

[This review was collected as part of a promotion.] Onnit Alpha Brain powder has a decent taste and mixes well, but I didn’t notice a big difference in focus or clarity. It might work better for others, but for me, the effects were minimal. The flavor isn’t too bad and you get a good amount for the price.

effect is not too strong

[This review was collected as part of a promotion.] I tried Alpha Brain. It helps me stay more focused and gives a sense of mental clarity. The effect is not too strong, but I noticed better attention and memory. I also like that it only requires one capsule a day

Onnit AlphaBRAIN Memory Focus

[This review was collected as part of a promotion.] I like the newer packaging of this product. It has no taste because they are in capsule form Also it seems to be effective for me because it helps with memory, promotes focus, mental processing, helps with flow state (the feeling of being "in the zone") . Key Ingredients: •L-THEANINE •PHOSPHATIDYLSERINE •ALPHA GPC •HUPERZIA SERRATA EXTRACT •VITAMIN B6 “𝕀 𝕣𝕖𝕔𝕖𝕚𝕧𝕖𝕕 𝕥𝕙𝕚𝕤 𝕡𝕣𝕠𝕕𝕦𝕔𝕥 𝕗𝕠𝕣 𝕗𝕣𝕖𝕖 𝕗𝕣𝕠𝕞 @𝕀𝕟𝕗𝕝𝕦𝕖𝕟𝕤𝕥𝕖𝕣 𝕒𝕟𝕕 @𝕠𝕟𝕟𝕚𝕥 𝕚𝕟 𝕖𝕩𝕔𝕙𝕒𝕟𝕘𝕖 𝕗𝕠𝕣 𝕞𝕪 𝕙𝕠𝕟𝕖𝕤𝕥 𝕣𝕖𝕧𝕚𝕖𝕨.” @influenster #complimentary @onnit #getonnit #AlphaBRAIN #CognitiveEnhancement #Focus

Clear Focus Without the Jitters !

[This review was collected as part of a promotion.] I’ve been using Alpha Brain for a little while now and I’m really impressed! The ingredients are clean and natural — no weird stuff, which I love. The packaging looks nice and feels premium. Taste-wise, I tried the capsules so there’s no strong flavor, which is a plus for me. In terms of value, it’s a bit on the pricey side, but I think it’s worth it for the quality. Most importantly — it actually works! I feel more focused and clear-headed, especially when I have a busy day ahead. Definitely a great support for productivity.

Truly gives you more focus!

[This review was collected as part of a promotion.] The Onnit Alpha Brain works so well! It is super effective and truly helps me feel more alert. The ingredient quality is healthy and there is a mild taste from the capsule. The packaging makes it easy to use and safe from children. Truly worth the money!

Surprising supppement

[This review was collected as part of a promotion.] Alpha Brain helped improve my cognitive focus and increased the effectiveness of my study habits. No artificial taste was noted, and the capsules are easy to digest. Compared to other supplements on the market, this product balances cost and effectiveness very well.

Didn’t work for me

[This review was collected as part of a promotion.] This is the type of product I want to love more than I do. The Alpha Brain capsules are designed to help to promote memory, focus, and mental processing; however, I don’t feel like it achieved any of those claims for me. When taking these I didn’t experience any positive or discernible difference in regard to these areas. I really wanted this to work because it would be an amazing boost to my work and daily life if it did. I love that it is caffeine free and that I didn’t experience any negative side effects, but I really didn’t experience any benefits at all.

Not sure...

[This review was collected as part of a promotion.] From the research I did, this seems to be a good brand. The list of ingredients is good too. I didn't notice an improvement in my ability to remember things, but maybe I needed to take it longer? I'm not sure...

Not worth the money

[This review was collected as part of a promotion.] I in all honesty did not notice any difference and for the price of this product I really don’t think it’s worth it. It’s your average packing. The ingredients seem OK but I honestly don’t think this product works. They’re far better supplements for the money that they want for this.

Works

[This review was collected as part of a promotion.] This thing works. I took 2 with a light snack, and within 20 mins, I felt something. I was definitely focused! The one draw back for me was that my eyelids started twitching, which was annoying. The next few days I just took one and that seemed to be the better choice for my body. Doesn't have a taste, and it's your standard packaging. I don't think this will be a continuous supplement I take, but maybe when I'm having a deadly tough time focusing
