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. Review: منتج رائع - ممتاز Review: Phenomenal product - dissolves easily, tastes great - Dissolves very well compared to other brands. Flavor is fantastic (I went with kiwi strawberry.) Mix with a vanilla whey protein for a great post workout shake! ## 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B019STF652 | | Age Range Description | Adult | | Best Sellers Rank | #9,766 in Health ( See Top 100 in Health ) #63 in Endurance & Energy Consumables | | Brand | EFX Sports | | Brand Name | EFX Sports | | Color | Neutral - 2 Lb | | Container Type | Bottle | | Customer Reviews | 4.4 out of 5 stars 88 Reviews | | Diet Type | Gluten Free | | Dosage Form | Powder | | Flavor | Kiwi Strawberry | | Flavour | Kiwi Strawberry | | Global Trade Identification Number | 00737190002681 | | Item Dimensions | 12.4 x 12.4 x 19.4 centimeters | | Item Form | Powder | | Item Weight | 1 Kilograms | | Item dimensions L x W x H | 12.4 x 12.4 x 19.4 centimeters | | Item form | Powder | | Item weight | 1 Kilograms | | Manufacturer | EFX Sports | | Manufacturer Part Number | AAP113CK-1 | | Material Features | Gluten Free | | Model Name | Sports Karbolyn Fuel | | Model Number | 737190002681 | | Number of Items | 1 | | Primary Supplement Type | Karbolyn | | Primary supplement type | Karbolyn | | Product Benefits | Endurance | | Special Ingredients | Gluten Free | | Total Servings Per Container | 18 | | UPC | 737190002681 | ## Product Details - **Age range (description):** Adult - **Brand:** EFX Sports - **Flavour:** Kiwi Strawberry - **Item dimensions L x W x H:** 12.4 x 12.4 x 19.4 centimeters - **Item form:** Powder - **Item weight:** 1 Kilograms - **Package information:** Bottle - **Primary supplement type:** Karbolyn - **Product benefits:** Endurance - **Special ingredients:** Gluten Free ## Images ![Karbolyn Fuel | Fast-Absorbing Carbohydrate Powder | Carb Load, Sustained Energy, Quick Recovery | Stimulant Free | 18 Servings (Kiwi Strawberry) - Image 1](https://m.media-amazon.com/images/I/71OmtyH+inL.jpg) ## Available Options This product comes in different **Size, Flavor** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ منتج رائع *by S***D on 23 August 2025* ممتاز ### ⭐⭐⭐⭐⭐ Phenomenal product - dissolves easily, tastes great *by E***S on 12 June 2021* Dissolves very well compared to other brands.
