## Features

- FAST-ACTING FUEL: Karbolyn is a clinically studied (with peer-reviewed, published research) carbohydrate supplement 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 Fuel always meets label claims and is 100% banned-substance free (certified by Informed Sport). With any EFX Sports product, you'll know that you're getting a pure, potent, and safe 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.
