Elite athletes know they must push harder and harder to achieve the highest levels of performance. When it comes to Sports Drinks, they need the one that's Formulated To Win! — Karbolyn Hydrate. Our researchers have developed what they believe is the perfect formula to help athletes rehydrate, fight fatigue, and quickly restore critical electrolytes.*

Athletes need real fuel, not sugar, for sustained energy and endurance. Karbolyn Hydrate is sugar-free, yet it can power you through the most grueling workout, competition, or anything that requires extended energy at peak levels.*

Maximum performance requires maintaining a proper balance of key electrolytes, such as sodium and potassium. Unfortunately, other drinks include too much sodium which can disrupt vital potassium levels. But not Karbolyn Hydrate! It contains a precise ratio of the 4 electrolytes (Sodium, Potassium, Magnesium, and Phosphate) critical to sports performance and recovery.

So grab a cup or shaker and find out why Karbolyn Hydrate is Formulated To Win!*

don’t hit the wall, break through it with Karbolyn

Have you ever experienced “hitting the wall” while training or participating in your favorite sport? When your body runs out of fuel too soon, it literally goes into ‘survival mode’, killing your performance when it counts the most. One moment you are performing at your peak, and the next minute you can hardly walk or move. It’s an athlete’s worst nightmare! Strength and performance athletes have been searching for the perfect “fuel” to help them achieve sustained optimal performance in the gym and on the field. Thanks to Karbolyn, that search is finally over.*


Karbolyn represents the dawn of a new era of carbohydrate supplementation. Derived from potato, rice and corn, this fast-acting, long-lasting, high-performance compound offers the best of both simple and complex carbohydrates.

Simple carbohydrates have the ability to enter the bloodstream quickly. This may be good for a quick burst of energy but not for sustained endurance.

Complex carbohydrates do provide sustained endurance. But, they are slow to digest, leaving you feeling bloated and lethargic.

KARBOLYN delivers the best of both worlds

Karbolyn is absorbed into the bloodstream like a simple sugar. It has also been proven to be absorbed as quickly as pure Dextrose (a simple carbohydrate). It still provides sustained energy!*

don't take our word for it. what does the data say?

KarboLyn Study Data
Re: IRB No : 29443/1; KL-001
Study: July 2014–March 2015

The Clinical Study sought to document whether or not KarboLyn has a positive and sustainable impact on blood sugar levels in normal adults during aerobic activity. A total of 24 male and female adults were randomized to receive 50 grams of either KarboLyn or a sugar drink (dextrose). Blood was drawn before and during the two hour study, according to the protocol, and physiological responses were recorded.

Data Obtained From Participants Indicated that a simple sugar promoted a steep drop (defined as a drop of more than 10 points or greater than 1 mg/dl of glucose per minute, or more) at a predictable point in time.

KarboLyn gave an overall smoother decline in blood glucose level.*

This study was funded by a Grant from the Montana Board of Research and Commercialization Technology.


Complex carbohydrates do provide sustained endurance. But, they are slow to digest, leaving you feeling bloated and lethargic.


However, Karbolyn uses a proprietary multi-stage “Enzymatic Milling Process” to reach optimal molecular size. This yields a superior carbohydrate for quick gastric emptying without any side-effects (such as stomach bloating or cramping) that is rapidly absorbed into the bloodstream.

Fast burning carbs with electrolytes that works great. Taste just like Lemon Lime Gatorade. Mixes and tastes great with vanilla protein. Wish there was an unflavored version.
