## Overview

EFX Sports Karbolyn Fuel is a fast-absorbing carbohydrate powder derived from potato, rice, and corn, designed for elite athletes seeking rapid muscle fuel and sustained energy without crashes. Clinically studied and triple quality-tested, this stimulant-free, gluten-free, and vegan-friendly formula supports peak performance, endurance, and quick recovery across all training phases.

## Description

Performance Carb. Energy. Endurance. Recovery. Gluten Free. 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.

## Features

- FAST-ACTING FUEL: Karbolyn is a clinically studied (with peer-reviewed, published research) carbohydrate supplement powder sourced from potato, rice, and corn. It’s specifically designed for elite athletes looking for a fast, safe, and effective way to quickly and easily load their muscles with lasting energy and promote faster recovery.
- PEAK PERFORMANCE: Karbolyn enters the bloodstream like a simple sugar, yet it still provides sustained energy without the crash. It's absorbed faster than dextrose, simple sugar, bread, rice, and other carbohydrate products. Enjoy pre, intra, or post training to maximize and maintain high-intensity training, power output, and increase muscle fullness & pumps.
- ALL CARBS AREN'T CREATED EQUAL: Unlike simple carbs that tend to cause a spike and crash or complex carbs that are slow to digest, leaving you feeling bloated and lethargic, Karbolyn combines the best of both by providing you with fast absorption and sustained energy without the bloating or crash. Plus, Karbolyn is 100% sugar-free, gluten-free, stimulant-free, and vegan-friendly.
- MANUFACTURED IN-HOUSE: EFX Sports is part of a very small, elite group of brands who actually make their own products. That’s why we guarantee Karbolyn always meets label claims and is 100% banned-substance free (certified by Informed Sport). With Karbolyn, you'll know you have a pure and potent carbohydrate product.
- 3X QUALITY TESTING: At EFX Sports, we proudly own every phase of the manufacturing process to ensure what's on the label is what's in the bottle...without question. In fact, every EFX Sports product must pass 3 critical quality checkpoints—before, during and after production.
