EFX Sports - Karbolyn Fuel Performance Carb - Neutral

WHAT IS THIS “PERFORMANCE CARBOHYDRATE” KARBOLYN®?
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. However,
they can also stimulate a strong “spike” and subsequent “crash” due to a rapid rise
and fall of insulin levels. 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, and can leave you feeling bloated and lethargic.*


KARBOLYN® DELIVERS THE BEST OF BOTH WORLDS
Karbolyn® is absorbed into the bloodstream like a simple sugar but without the
typical crash caused when your muscles run out of fuel. It has also been shown to be
absorbed as quickly as pure Dextrose (a simple carbohydrate). Yet, it still provides
sustained energy without “crashing”.*


DON’T TAKE OUR WORD FOR IT...WHAT DOES THE STUDY SAY?
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.
Data obtained from participants indicated that a simple sugar promoted a steep
drop and subsequent “crash” at a predictable point in time. Karbolyn® gave an
overall smoother decline in blood glucose level.*
