EFX Sports Karbolyn is SUPERIOR to other carbohydrate powders. Karbolyn quickly fills your muscles with glycogen for maximum energy, performance, and recovery! It’s a slow-digesting carbohydrate that gives you more than 2 hours of cellular energy!

EFX Sports Karbolyn - The Best Fuel For Your Hardcore Workouts!

Most carbohydrate powders are not a good choice for quick glycogen loading or absorption of nutrients. These carbohydrate powders are processed, so they do not allow fast absorption. In comparison, Karbolyn uses a multi-phase “Enzymatic Milling Process” to reach optimal molecular size. This means Karbolyn is an advanced bio-engineered carbohydrate created for quick gastric emptying with no cramping or bloating.

Other companies make claims like ours, but only one company makes Karbolyn… EFX Sports!

Have you ever “hit the wall” during your workouts or athletic events? Your body uses up its fuel supply quickly. That means poor performance. One moment you’re at your best, and the next it's all you can do to complete your set. 

At a time like this, don't rely on dextrose, pasta, or any of the other inferior carbohydrate sources. Rely on EFX Sports Karbolyn and dominate your workouts!

Karbolyn - Fast Absorption, Long Lasting Energy!

EFX Sports Karbolyn absorbs 18.21% quicker than glucose! Also, it has an extended energy response, unlike glucose. Compare that to glucose which peaked at 30 minutes but began to drop off dramatically after that. Glucose is completely gone within 120 minutes.

Karbolyn peaked at 45 minutes and was active after 120 minutes. This means EFX Sports Karbolyn is a better choice for a rapid energy surge. It supplies enough cellular energy for an entire workout, athletic event, or endurance event.

Who Can Use EFX Sports Karbolyn?

Karbolyn is for bodybuilders, strength athletes, runners, cyclists, and CrossFit enthusiasts - anyone that wants optimal performance! It quickly fills your muscles with glycogen for ultimate endurance, performance, and recovery. It absorbs 18.21% faster without any crash or spike! We created Karbolyn with a “time-release” feature - it provides over 2 hours of cellular energy! We’re not talking about central nervous system stimulant-based energy, we’re talking about cellular energy. That’s a big difference! That’s the kind of energy that powers your muscles through their most brutal and demanding workouts. 

Karbolyn is an exclusive compound because of its molecular size and structure. Plus, it’s derived from potatoes, rice, and corn. Also, it comes in amazingly delicious flavors - including Cherry Limeade, Green Apple, Kiwi Strawberry, Orange, Strawberry, and Neutral. It’s zero-sugar, low-sodium, gluten-free, and mixes instantly. Just mix in one scoop with 14-16 ounces of water in your shaker cup and you’re all set! It will not clump or gel, and there’s no bloating or cramping. It’s also Informed-Sport Certified and Banned-Substance Free - and it’s manufactured by EFX – we control all production. Now that sounds like the perfect carbohydrate powder!
