The ingredients of CLAREX are formulated in precise amounts to run this major bioenergy pathway in your body. This cycle can run infinitely as long as there are the right ingredients added to it. Hans Krebs won the Nobel Prize for this work. Since this is how your body is designed to work, you get a clean, productive feeling when you take CLAREX.


Act on your neuroreceptors, which can be saturated or depleted. This is why you feel the crash and also why you need to consume more of it over time for it to work. It leaves you with an unnatural feeling, either when you are on it, or after you take it.

  • The origins of Clarex

    I created CLAREX seeing deconditioned patients in the hospital. We successfully treated these patients with IV medications and nutrients. I thought, 'I work insanely long shifts. I could use some of that. Wouldn't it be great in a tablet form for anyone to use?' Thus CLAREX was born. I hope you find it helpful to your daily routine as well as times when recovery is needed."

  • How to use

    Take one serving daily in the morning AND
    Take one serving as needed at least 6 hours later
    < 150lbs one serving = 1 tablet
    > 150lbs one serving = 1-2 tablets


  1. I go to school, drink coffee in the morning, and have trouble staying alert in the afternoon and I am 165 lbs.

    Take 1-2 Clarex tablets at 8 AM with your coffee and when you want to be alert in the afternoon, take 1-2 Clarex tablets at 2 PM or afterwards. Unlike caffeine, Clarex will not affect your ability to sleep.

  2. I went to the annual holiday party and had one too many. I heard Clarex helps with post-celebration recovery, but I am not a regular Clarex user. I weigh 120 lbs.

    Take 1 Clarex in the morning with a large glass of water. Clarex increases productivity, especially when your body needs recovery. Alcohol inhibits the Krebs cycle and Clarex gets it back going. The water helps with rehydrating your body.

  3. I drink Red Bull in the morning, can I take Clarex?

    Yes, you can take Clarex. You can take Clarex with any caffeinated product since it does not have caffeine and has a different mechanism of action.

CLAREX allows me to take in my day and all the comes with it one task at a time. With so much input coming from so many direction, having CLAREX clarity helps me answer the day’s questions one at a time.

"The life of a musician is not always glamorous as it’s made out to be. Lots of late nights of packing up equipment on the road turn into early morning drives to the next state. Whether I need to focus after a long night on tour, or meet a 9 a.m. deadline after a show, CLAREX helps me power through and get it all done."

"Clarex is legitimately a dose of cognitive clarity. I have been diagnosed with ADHD, and was prescribed medications to help me with my studies. These medications became problematic for my active and healthy lifestyle as my appetite and sleep schedule were both distorted. These days, I take a couple of Clarex in the morning and I’m good to go for the whole day. I can nap between classes and eat properly after working out or surfing. I find that Clarex gives me the additional focus and mental clarity that helps me streamline my busy collegiate life. I feel much healthier now that I am taking Clarex."

”As a former competitive body builder and working professional, I had tried everything, trying to reach that extra edge. Pre-workout energy drinks would work for short periods of time, and then drop me, mid task. I tool Clarex with my energy drinks and Immediately noticed and increase in focus and cognitive thought. It was an amazing feeling. I told all of my lifting buddies and work associates. CLAREX! where were you 10 years ago? I have an increased quality of life because I can now look at that day knowing that focus is one tablet away. I want to meet the guys that invented this stuff. Thank you for the clarity.”

"I’ve been taking Clarex for nearly a month and have seen some significant improvements in my overall well-being. I have struggled to find the quintessential work life to pay the bills and mortgage while maintaining an active, healthly lifestyle. Now that I’m working in Boston and am commuting from out of state (Rhode Island), I experience long exhaustive days. I take Clarex daily (sometimes twice) and have found it gives me the cognitive focus without the crash of caffeine pills and energy drinks. I can even savor some of the edge for a work out at the gym when I get home, knowing too that what I’m taking is completely composed of natural ingredients. It’s not the ultimate happy pill, don’t think one exists, nor should it, but Clarex comes honestly close to achieving that."

"I consider myself a very active person. When I was running 3-4 times a week training for a marathon and working full time as a nurse practitioner in the stressful hospital environment, I was feeling tired and mentally exhausted. In my profession, I need to constantly stay focused and think clearly. A friend of mine told me about Clarex. At first I was skeptical because occasionally I would take vitamins or supplements but never felt like they made a difference. Then I tried Clarex. Right away I felt a difference. I am able to stray sharp, with a mental clarity that is noticeable and my memory is also greatly improved. I work out in the morning, take my Clarex then enjoy a productive busy work day, knowing that the supplement I'm taking is all natural and enables me to live a healthy active lifestyle with a clear mind."

"I'm not one to push a product but what I've found is that Clarex gives me the edge I need to concentrate. I'm 48 and five years ago I had major heart surgery. One of the complications that resulted from the surgery is that I suffer from major depression. I'm now coming out of that depression, thank God. I still have some concentration issues stemming from it and this is where the Clarex comes in. When I know beforehand that concentration is going to be an issue I pop two of them and go about my business. It's not until after I finished the task at hand that I realized I was clear and focused throughout the project. It doesn't matter if I'm cross country skiing for fitness, performing difficult navigation planning or even in a job interview. It just seems to help. I welcome this with all that is me. I can't speak for anyone else but I will tell you it works for me. I'm now a new loyal customer."
