When you’re grinding through an ultramarathon, halfway through an Ironman, or hammering out a ride, one thing can make or break your performance, fuel. Not just any carb will do, you need fast energy that won’t spike, crash, or wreck your stomach at any point in your race. That’s where Karbolyn® comes in.

This isn’t your standard sports drink sugar or maltodextrin. Karbolyn® is a patented performance carbohydrate designed to absorb as fast as simple sugars but deliver the steady, sustained energy of complex carbs. In other words it acts quick, lasts long, is and easy on your gut.

What Is Karbolyn?

Karbolyn® is an engineered carbohydrate derived from potato, rice, and corn using a unique enzymatic process. This process rearranges the starch molecules into a form (like a train) your body absorbs rapidly without bloating or digestive distress. Think of it as a high performance carb that combines the best of both worlds:

• Fast acting like simple sugars for quick energy delivery.
• Sustained release like complex carbs to keep your glycogen levels stable.

Originally developed for athletes to carb-load efficiently, it’s now used by endurance runners, cyclists, triathletes, and anyone who needs reliable energy over long training sessions or races.

Why Karbolyn® Beats Ordinary Carbs

1. Super fast absorption without the crash
   In a head-to-head study, Karbolyn® was absorbed 18% faster than glucose but unlike glucose, it didn’t create a sharp blood sugar spike followed by a crash. Instead, energy levels stayed elevated for up to two hours perfect for long-duration performance.

2. More power than waxy maize or maltodextrin
   Compared to other “fast carbs,” Karbolyn® delivers longer-lasting energy. A 50-gram serving fueled workouts for roughly an hour, while 100 g extended that boost to nearly two hours, all without stomach discomfort.

3. Stable blood sugar for consistent output
   Even in pre-diabetic test subjects, Karbolyn® kept blood glucose levels steady and avoided prolonged highs, critical for endurance athletes who need smooth, reliable power instead of peaks and dips.

4. Clean, versatile, and athlete-safe
   1. Sugar-free, gluten-free, stimulant-free, vegan-friendly
   2. Mixes easily, no clumping or bloating
   3. Informed-Sport certified — trusted for drug-tested athletes

How to Use Karbolyn®

Karbolyn® is about as versatile as it gets. You can mix it as needed for the effort, distance, carb/hour, body size, etc.

• Before workouts
• During workouts
• After workouts

It’s highly soluble, so you can sip it during your event without stomach issues, a major win for runners and cyclists who know how punishing mid-race gut problems can be.

The Balanced View

Some athletes argue that whole-food carbs (like oats, potatoes, or bananas) can fuel endurance just as effectively and they’re right if you’ve got time to digest. Karbolyn’s strength is speed, predictability, and convenience. It’s engineered to do in minutes what whole foods might take hours.

Bottom Line

If you train or race for hours at a time, Karbolyn® is a powerful tool to keep you moving strong and steady. It loads fast, fuels long, and won’t wreck your gut. Whether you’re an elite endurance athlete or simply serious about performance, Karbolyn® delivers clean, reliable energy when you need it most.
