Really helps with focus!

[This review was collected as part of a promotion.] I’ve been using this for almost a month now and I’m really impressed with how much it’s helped with my focus! One of its main ingredients is an amino acid called L-theanine, which is known to support brain function. It also includes a short list of other supplements that support memory, focus and reaction time. I really like the fact that it’s caffeine and gluten free! The pills aren't that big and don't have a strong taste. The packaging is nice and the bottle is easy to store. Overall, I’m very satisfied with the results so far, I highly recommend you try this yourself!

Became little more concentrated

[This review was collected as part of a promotion.] I’ve been trying out it for a week now, hoping to boost my focus and mental clarity during busy days. The capsules are easy to take, and I really appreciate the fact that they use natural ingredients—no weird chemicals or caffeine jitters. I didn’t turn into a productivity machine, however I did notice a subtle improvement in my concentration, especially in the late afternoon when I usually start to lose steam. My thoughts felt a little more organized, and I didn’t reach for coffee as often. Overall, it’s worth trying if you’re looking for a natural nootropic to support focus and memory, just keep your expectations realistic.

Didn’t feel a change

[This review was collected as part of a promotion.] I didn’t feel great on this supplement. Stomach was a little upset and I didn’t feel a change in my focus. The pills were easy for me to swallow but just not something I would continue to buy in future.

Seem to work!

[This review was collected as part of a promotion.] I got these for my brother. He has memory problems from the way he was born. They seem to be working. The ingredients seem natural. I like the size of the bottle. They are a little bit expensive, but work much better than other memory vitamins we have tried.

Alpha Brain

[This review was collected as part of a promotion.] These Alpha Brain capsules are easy to take. I don’t notice much of a taste. It is caffeine and gluten free. Make sure you eat before taking these or you’ll feel lightheaded and nauseous. After taking these for a couple weeks I have noticed some changes. My mental clarity improved. I feel like everything was more clear. I was more focused and organized.

Focus fine

[This review was collected as part of a promotion.] These are great! They seem to work really well as I definitely feel like I am able to focus better and get more done. Don’t like the taste but it’s easy to get past. Definitely want to see how they work long term!

Stay focus !!!

[This review was collected as part of a promotion.] Perfect brain supplement to start your day! I’m definitely more alert and better able to focus for longer periods of time. I will definitely continue to take it. There is no scent or after taste. Good ingredients like vegetarian capsules. Small bottle.
