Support daily task

[This review was collected as part of a promotion.] I've been taking Onnit Alpha Brain for a week now, and I’m pretty impressed. The boost in focus and mental clarity is noticeable, especially when I’m tackling challenging tasks. I also appreciate that it doesn't come with the jittery side effects some other nootropics do. The only downside is the price—it’s a bit on the higher side. Overall, it’s a solid supplement and definitely worth trying if you’re looking to enhance your cognitive performance.

It will make you feel sick.

[This review was collected as part of a promotion.] I wanted to like this product a lot, but the truth is another one. The pills are huge, and the recommended dose is 2 every day with light meal. They made me feel so sick. After 1 hour, I started feeling a headache, and then, by time passed, it got worse with nauseas, almost throwing up. I definitely do not recommend this product.

Memory

[This review was collected as part of a promotion.] I received this product for free from Influenster and Alpha Brain in exchange for my honest opinion of the product. I am in my postpartum stage and these pills have helped me a lot with my concentration and memory. It’s a big bottle that can last you a long time. So I recommend trying them.

Help cognitive support

[This review was collected as part of a promotion.] I've been trying them for a week now and they are easy to swallow and digest. What I like most is that they are caffeine-free and that the ingredients they contain help with memory and focus, in addition to helping with cognitive support.

Works

[This review was collected as part of a promotion.] Having 2 toddlers at home and working full time can be challenging. We are often tired and have a hard time focusing. This product definitely helps with that!! It makes me feel more focused and less tired.

So far so good

[This review was collected as part of a promotion.] I received this Onnit Alpha Brain Supplement free for review. I have been taking it for a little over 2 weeks now. I have not noticed a huge difference but I have noticed a better ability to focus. The directions say that you can double your dose after time so I'm going to give that a try and see how well it works on the memory and reaction time. I plan to try this product for over a month and purchase another bottle so I can see!
