Doesn't last very long

[This review was collected as part of a promotion.] I've been taking these pills for a few days now, each dose consist of 2 pills, which are easy to swallow and I take them in the morning after breakfast or after working out. They don't feel heavy on my stomach. I have noticed a slight change. They have helped me stay more focused on my work. Since I take 2 pills daily the bottle doesn't last very Long.

Life giving product at a true value for the member

Sam's Club friends. Always wanted to try Alpha Brain but was too cost conscious to pull the trigger until I saw it come to Sam's Club. It's got an awesome value vs. Onnit.com and excited to try it. I've taken it for 4 days now and wow. I never expected the focus and added energy that these pills have given me. Truly floored and worth the $57 investment. Bravo to the team who created this product and if you're like me and can get easily distracted...Alpha Brain is your next secret power. Run, not walk to Sam's Club and get an incredible product at a great value.

Great product!

[This review was collected as part of a promotion.] I love that this product has natural i gradients and is caffeine- free. No jitters or sweats. A great addition to my supplements as a busy working mom. Capsules are not huge and they digest smoothly. No upset stomach or nausea which is common for me.

👍🏻

[This review was collected as part of a promotion.] Excellent ingredients and it enhanced my alertness for my tests. I was able to study effectively, focus and retain information. I would make a repeat purchase. I had to consume it with food. I highly recommend.

They’re ok

[This review was collected as part of a promotion.] Not sure how I feel about these honestly. I didn’t notice much of a difference but maybe it’s due to the short duration of time that I took them. They may work with consistency but I don’t know. I will say they didn’t upset my stomach or cause any discomfort. No weird smells or anything either.

Thanks for leaving a review about your experience with Alpha Brain! We’re bummed to hear that you didn’t have the experience that you were hoping for. While we typically suggest trying out for 2 weeks to feel effects, being that we all have different needs, it's expected that we all respond to supplements a bit differently, and we're glad you gave it a shot.

Laser Focus

[This review was collected as part of a promotion.] I’ve been using this supplement daily and have noticed a real improvement in my focus. Working in an office requires a lot of mental clarity, and this has helped me to stay attentive and adapt to new responsibilities. Unlike other nootropics I’ve tried, it doesn’t make me feel jittery. I plan to continue purchasing and using long-term.

Amazing product. So thankful for it. I can finally

[This review was collected as part of a promotion.] For someone who struggles with paying attention to one task at a time, Alpha Brain has brought me back to earth and I am able to finish tasks in record time comparative to when I am not using it. There is no taste to the pills and no after taste once swallowed. The size of the pill is manageable as well. You definitely want to eat food prior to taking or else it will mess up your stomach. I love this product and cannot speak enough about it.

They're ok

[This review was collected as part of a promotion.] This supplement is good, I've had easy calm days without having hard time trying to stay focused throughout the day. Pill size is an the regular size. They don't have any bad smell, and they're tasteless pretty easy to swallow if you're used to taking vitamins/meds.
