Great cognitive support supplement

[This review was collected as part of a promotion.] I have been using Alpha Brain for about a month now and I can genuinely tell a difference. I have more energy, and am more focused through the day. Also do not seem to forget things like I used to. Easy to take, just one pill a day and contains healthy, natural ingredients. Must try if you suffer from cognitive issues.

Focused, Clear, and Ready to Go!

[This review was collected as part of a promotion.] These capsules have helped me stay on task longer, recall things more easily, and feel mentally sharper, especially during long work days, or when I feel exhausted. The packaging is easy to open, and the bottle feels high quality. I have not noticed any taste, which is a bonus. I also love that it supports reaction time, perfect for anyone who wants to stay sharp and alert without the crash that comes from caffeine-heavy alternatives. Highly recommend if you’re looking for that extra edge in your daily performance.

Alpha brain is amazing

[This review was collected as part of a promotion.] Packaging was great. Most vitamins have a nasty taste but not these they go down smooth and seem to be packed with amazing ingredients Day one of taking them but so I’m no sure how well they work yet but focus work has been a breeze

Strong smell make, it hard to swallow

[This review was collected as part of a promotion.] I tried these daily supplement for a few days. Tell the truth, it very hard to swallow and it has this rusty smell. I haven’t seen any difference so can’t really say it’s working or help with my memory. Maybe has to take more to see the result.

Not my favorite

[This review was collected as part of a promotion.] I am 42 years old, so I need brain support vitamins. I have tried a couple of different products. This one is not my favorite. Somehow, this one gives me a heartburn, especially when I take it at night time.

Game changing product!

[This review was collected as part of a promotion.] I have been wanting to take Alpha Brain for a long time, thanks to the trials. I started taking the product and have been a loyal fan since then. I have had numerous traumatic brain injuries from martial arts, and college football, and the clarity that I get from the product is impressive. I like the product so much that I began taking Total Human because I feel like OnIt is very much on to something.

Promising nootropic with a smooth focus boost—4 /

[This review was collected as part of a promotion.] I’ve been taking Onnit Alpha BRAIN for a week now, and I appreciate its clean, caffeine-free formula and sturdy packaging. The capsules are easy to swallow, and I’ve noticed a gentle lift in focus during my study and work sessions. It’s still early to judge memory support, so I’m giving it 4/5 stars and will reassess its effectiveness in a few more weeks.

They work

[This review was collected as part of a promotion.] The pills are pretty big and the serving size is 2 pills so I don’t know how often I will take them just because they are hard to swallow. I will say I believe these are effective as I noticed I was more focused after taking them. It did make my teeth feel weird/it felt like I was noticing my teeth more. If there are days I need to focus more or I am feeling tired I will probably take these but these are definitely not an everyday supplement for me. My husband came to the same conclusion I did about them. Not a love but not a hate either!

You may not notice a difference right away

You will need to take these for at least a week for this to work. After my first week, I did not think it helped much. Then I decided to skip a day. It was certainly noticeable that whole day. I work from home and found myself easily distracted, tired, and not motivated to accomplish much. I resumed taking them again the next day and have been a fan ever since. I get far more accomplished in less time than before.

When doubt turns to confidence!

I bought it thinking, well, what the heck, it can't hurt. I wasn't too sure about the first few days I used it. I was feeling good anyway but today, third day trying, it made a difference. I am in customer service and I have to be alert and articulate or the clients will eat me alive. LOL. I don't feel jittery and I am jazzed to keep taking calls, helping clients and am planning on cleaning out my fridge after work too. What? LOL
