This product is great for reduced brain fog and more mental clarity.

Love this product for it increased my cognitive function, memory and motivation to get my tasks done throughout the day. Definitely recommend to anyone looking to get an edge.

Great product. Would buy again.

Una amiga mía me la recomendó y me regalo 5 para probar y si me gustaron y por eso yo también pedí las mías

This is one of the best- it’s pricey for a reason. I’ve taken a lot of different ones. This one’s at the top.

I've supplemented with Gingko Biloba and Ginseng for about 25 years now. I struggled with energy and memory retention all throughout high school but it wasn't until after I graduated did I start trying supplements. Gingko Biloba alone had been extremely beneficial for memory recall but my energy level struggles at times. Two months ago, I began supplementing with "X" only adding 2 capsules per day to my supplementing regime & energy, focus & recall have seemed balanced since. The full dose is six capsules but I like to micro dose as much as possible. I haven't felt the need to take more than 2 capsules daily...

I am no stranger to the world of nootropics. And because of that, I've been in the habit of playing guinea pig on myself for years now with different formulas and stacks that I put together on my own. While this product is bit on the pricey side, especially when you're only getting a half month's worth, there is a massive difference between the "generic" ingredient and the trademarked ingredients in nootropics. For instance, there are many suppliers that you can find online that sell formulas with ingredients like ashwaghanda, L-theanine, huperzine-A etc....but this particular formula has the patented/trademarked versions for almost all, if not all, of their ingredients - and there are a LOT of ingredients. The reason that this is important is b/c supplements are not FDA regulated. The trademarks provide the consumer with some sort of peace of mind b/c trademarked ingredients typically undergo double blind placebo studies, they are "cleaner" (ie. no filler) and the manufacturing of said ingredients go through rigorous QA processes. Because of that, they are a little more costly. Also, there are 6 pills per serving, which is OMG, however, the ingredient list reads like my kids' Christmas lists, it's crazy. Everything is in here to deal with memory, focus, concentration, emotional stability, all with neuroprotective long-term benefits. I know it's expensive, I also thought like WOW at first, but I have stopped taking the gambit of all other nootropics I was consuming during the day, which equaled out to less than 2 bottles of this supplement per month. There are other great nootropics formulas online, feel free to go down that Reddit rabbit hole. This is the only one that I've come across that is all-inclusive and available on Amazon. Try and see what you think! Jar says it takes about 2 weeks to fully kick in -- I felt 1000% honed in by Day 5.

Awesome supplement to help me stay layered focused on my work. Highly recommend.

Supplement works without any side effects like being jittery. Helps concentration and focus!

I just received my first order and can already tell a difference. Within an hour and a half I AM CALMER!

The difference is palpable. I feel like i can take on more work and that the time is being used properly. I noticed a bigger difference after i finished my first bottle and recommend people that have difficult projects to try it out.

I absolutely loved xbrain. It has given me a competitive edge for work, and literally a blessing i look forward to taking every morning. Best nootropic on the market.

This product has helped tremendously with my productivity, focus, and mental clarity. I have found the missing link.

Great product have used for several weeks and works as advertised!

I have tried Alphabrain and Qualia, but noticed the biggest impact with X! I feel noticably sharper and have less issues staying focused while taking the product.

As someone with ADHD, I feel more focused when studying and less inclined to become distracted. With that being said, one still needs to exercise discipline consciously as nothing is a magic cure. However, I do feel that X Brain gives me an edge when I'm studying for the LSAT where I am more easily able to retain information and apply concepts to get a better quality of studying. 5/5 product in my opinion. I use X Brain in combination with Caffein/ Ashwagandha/ Tongkat Ali and Fadogia Agrestis. I believe this to be a great combo with X Brain.

Hi, this is my first day trying X. I'm looking forward to feeling the effects of X, and getting more done. I procrastinate allot, but I heard that X is good with helping with focus and productivity. I will write another review after a few days on X. Thank you for making such a well packaged product.

X has been a game changer in my life. I am a father of 2 kids who play multiple sports and a husband and engineer by day. I feel focused and better organized with my calendar. I feel more motivated to take on the day. X is daily part of my daily routine along with my multivitamin. I am a believer of peak performance with mind (learning) body (exercise) spirit (meditation) and loving and living a healthy lifestyle.
