Terrible sickness

Just took my first 2 doses this morning. I did have it with food.. excited to start my Friday. I had every intention on going to the gym later but 40 mins after taking this supplement I got so nauseous. It’s been 2 hours & I’m drinking ginger tea, I have 2 toddlers I need to care for and this has got to be the worst day of my life. ): Seriously regret taking this supplement

Thank you

[This review was collected as part of a promotion.] Alpha Brain helped me feel a bit more focused and clear-headed, especially during busy days. I liked that it’s caffeine-free, so there were no jitters. However, the effects weren’t dramatic. Also, I wish the ingredient amounts were more transparent. Overall, worth trying if you're curious, but results may vary.

Great for focus and memory

[This review was collected as part of a promotion.] I like this Alpha Brain, since I became a mom I was constantly forgetting everything and not being focused on my regular duties. Now I can feel like my brain is coming back to the senses little by little. Since I'm not a big fan of big pills I break them and dilute them in my orange juice or beverage.

Great!

[This review was collected as part of a promotion.] Was super excited to try these brain vitamins out. I started taking them last week when I received them and I do feel like I notice a difference. I feel more focused during the day and not as tired. I’m going to continue taking them to see if I continue to see improvements. Super easy to take and don’t have a weird taste. Made up of natural ingredients and also super affordable.

Memory Supplement

[This review was collected as part of a promotion.] I have been searching for a memory and focus supplement for a while, so I was really excited to try this one. I noticed a subtle difference, but it wasn’t significant, so I’d say it’s not essential after all.

Not bad

[This review was collected as part of a promotion.] I love the packaging. It is also nice that it has ingredients that actually help with memory such as amino acids, B6, and other herbal extracts. Although i havent really seen much with my memory or focus

Love it

[This review was collected as part of a promotion.] This nootropic supplement helps with focus and mental clarity. I notice that on days I take it, I feel more dialed in and less scattered, especially during work or reading sessions. It doesn’t give a jittery or overstimulated feeling like coffee sometimes does, which I appreciate. That said, the effects aren’t super dramatic—it’s more like a subtle boost rather than a night-and-day difference. Also, it seems to work better when taken consistently rather than expecting immediate results. It might not be for everyone, but for me, it’s been a nice little addition to my routine.

I like the ingredients

[This review was collected as part of a promotion.] Packaging is great. The pil is easy to swallow. Ingredients are natural and like that. It has aftertaste, but it is not too bad. At this time, it is too early to say if it is effective, but i am hopeful.

On the struggle bus?

[This review was collected as part of a promotion.] If you feel like you’re on the struggle bus some days like me this may help! I struggle with not being able to concentrate and focus on tasks at times and it feels like nothing helps me stay in the zone to complete them. I really like that this nootropic doesn’t have any caffeine so it doesn’t make me feel jittery or keep me awake if I take it in the afternoon. Because the serving size is taking 2 pills per day this bottle of 30 capsules will only last 2 weeks. I suppose if you plan to only take it very short term that is ok but I would have preferred a bottle that actually lasts an entire month.
