Perhaps more time?

[This review was collected as part of a promotion.] So neither my husband nor I was impressed by these. We didn’t notice any changes in our memory, focus or reaction time. In fact, the time I thought I did, I only taken one capsule so I’m not sure that’s possible. I didn’t taste anything since these are in capsule form but I didn’t like that I need to take 2 daily. I needed to research the ingredients to truly understand what each blend contained. The packaging and branding it extremely attractive. I will say that these were not easy on my digestion. I felt a little nauseous twice after taking them. My husband did not feel any side effects at all. So it was a little disappointing. Perhaps they need time to build up in our system? I was under the impression that it was an immediate effect. I’d try other products just because my husband and I are curious about what else they have to offer and we love working out. So we will see. I’ll leave it up to you to try for yourself. I wouldn’t say they’re worth their value since we didn’t notice results. Thanks to Influenster and Onnit for the opportunity to try this one.

Sharp Focus Without the Jitters!

[This review was collected as part of a promotion.] I’ve been using Alpha Brain for a few weeks now and have noticed a real improvement in my ability to focus, especially during long work sessions or when I need to stay mentally sharp. What I love most is that it doesn’t give me the jittery feeling that other nootropics or caffeinated products can cause. It feels more like a smooth, natural boost. I’ve also noticed a slight improvement in memory and reaction time, particularly when multitasking. The fact that it’s stimulant-free is a big plus for me. I take it in the morning with breakfast, and it kicks in gently within an hour. My only reason for giving 4 instead of 5 stars is the price—it’s a bit on the higher end for just 30 capsules, and I wish it came with a larger quantity for better value. Still, it’s a solid supplement if you’re looking for daily cognitive support!

FOCUS

[This review was collected as part of a promotion.] Felt like this product was OK does keep you in a mental focus state especially when focusing on multiple tasks. It is effective and does work for multiple reasons. Doesn't have a taste to it but pills are a little big so if you have trouble taking pills maybe find a different route of taking them if this interests you.

Great supplement to boost focus, memory, and react

[This review was collected as part of a promotion.] I’ve been taking Alpha BRAIN daily and noticed a real improvement in my focus and mental clarity. The capsules are easy to take, the packaging looks great, and I appreciate the clean ingredient list. It helps me stay sharp during busy days and I love that it fits easily into my morning routine.

No results

[This review was collected as part of a promotion.] After using this product, I didn’t notice any positive results. The product doesn’t contain any dangerous ingredients, which is great. However, I didn’t notice any increased brain function. In fact, I started getting headaches. May or may not be related.

Good Focus

[This review was collected as part of a promotion.] I received this product free from ONNIT and Influensters for my honest review. Alpha Brain has been something I have enjoyed trying. It helps with focus throughout the day and I felt more alert. It did not make me feel weird like some supplements do, but it is a mild feeling of just being alert. They are easy to take and use and do not have to be taken daily or anything. I would recommend them just to have a little extra focus when needed.

part of my daily routine.

[This review was collected as part of a promotion.] Alpha Brain has become part of my daily routine.” I started taking Onnit’s Alpha Brain to help with mental clarity and focus during long workdays—and I can genuinely feel the difference. Within about a week, I noticed I was less scatterbrained and more in the zone, especially during meetings or deep work sessions. It’s not like a jolt of energy or a caffeine buzz—more like a subtle sharpening of your thoughts. I appreciate that it’s stimulant-free too, so there’s no crash. Definitely worth trying if you’re looking for a natural cognitive boost.

Alpha brain

[This review was collected as part of a promotion.] Was so excited for the opportunity to try this. It does give me increased focus without the crash of caffeine. I also sleep well in the evening after taking it. Overall, a great addition to my vitamins!
