Effective, high-quality, great for focus. 🌸

[This review was collected as part of a promotion.] I appreciate the complimentary from @Influenster and @onnit for the supplement. I’ve been familiar with Onnit for a while, as my husband has taken several of their supplements before and has always been very satisfied with the quality. When we decided to try Onnit Alpha BRAIN, he was the first to test it, and he definitely noticed the benefits. He felt more focused and mentally sharp, especially during tasks that required a lot of concentration. Seeing his results, I was even more intrigued. Onnit has a great reputation for using high-quality ingredients, and Alpha BRAIN lives up to that standard. It’s a solid choice for anyone looking to support cognitive function without relying on caffeine. Definitely worth trying if you want a natural boost in focus and mental clarity!

Great product

[This review was collected as part of a promotion.] This is such a great product in theory but I’m not sure if it states what it says it does. So far I haven’t noticed anything different aside from taking the supplement but maybe I just have to give my body some time to adjust to it.

alpha brand

[This review was collected as part of a promotion.] Useful for daily cognitive support as it helps to focus and memory as well as reaction time. Is usually taken to capsule with the light meal. Does not have any smell and it just swallowed it with water.

Thanks for reaching out and leaving a review! So sorry to hear that Alpha Brain did not work for you. Because everyone reacts differently to supplementation it's not uncommon to have different experiences. Please note that this supplement's main focus is to help support memory, focus, and processing speed - sometimes it can take time to notice these effects. That being said, if you are ever dissatisfied with your order, you can always contact our Customer Service team for further assistance!

Results may vary

[This review was collected as part of a promotion.] The capsules are easy to take and didn’t cause any side effects for me, but may result to varying from person to person. The ingredients are well-researched. It’s a bit pricey, however worth to try if you are curious about nootropics.

Great energy boost!

[This review was collected as part of a promotion.] The bottle comes with 30 capsules. The serving size is 2 a day. So this lasted about 2 weeks. I did not notice a difference in my ability to concentrate. I did feel less tired throughout the day with work and school. I took it daily at 9 am with food. I got nauseated every afternoon around 2-4pm. (Not sure why, but it ended when I stopped taking the pills.)

Onnit Apha Brain is the best

[This review was collected as part of a promotion.] Alpha Brain is a popular nootropic supplement designed to enhance cognitive function, improve memory, and boost mental performance. Developed by Onnit Labs, it's gained significant attention in the nootropic community .Improved Focus and Concentration.Alpha Brain's blend of ingredients, including Alpha-GPC and Huperzia Serrata, aims to enhance attention and concentration. Enhanced Memory and Learning*: Elements like Bacopa Monnieri may aid in memory formation and improve learning abilities. Mental Performance Under Stress .Ingredients like L-Theanine, renowned for its calming effects, can assist individuals in maintaining cognitive performance during stressful situations. My experiences vary, those improved focus, memory, and mental clarity. However, it's essential to consult with a healthcare professional before starting any new supplement regimen.

Caffeine-free focus

[This review was collected as part of a promotion.] My first usage impression is very positive. The combination of the ingredients looks very compatible with my lifestyle and diet and the fact that it doesn’t contain caffeine is a plus. The other thing that makes it a good supplement is no added sugars or other components. I like how it makes me feel like I slept my 8h and be active throughout the day. The number of capsules to take per day is just 2 and is perfect. I like it!

Decent product

[This review was collected as part of a promotion.] This definitely helps focus and mood. Its a mild increase in both not too much. 2 pills are necessary to feel the full effect especially if youre already tired. Impressive packaging and for the price a decent product. No taste but the ingredients are of quality. @influenster #complimentary @onnit #getonnit #AlphaBRAIN #CognitiveEnhancement #Focus

It’s ok

[This review was collected as part of a promotion.] Onnit Alpha Brain is a decent nootropic supplement, but the results were somewhat mixed for me. It claims to enhance focus and mental clarity, and while I did notice a slight boost in concentration, it wasn’t as significant as I had hoped. The effect was subtle, and there were days when I didn’t feel much of a difference at all. The capsules are easy to take, and I appreciate that the formula is made from natural ingredients. However, the price is on the higher side, especially given the inconsistent results. It might work better for some people, but for me, it didn’t fully live up to the hype. Three stars.
