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 | B07NQMLYMQ | | ASIN | B07NQMLYMQ | | Age Range Description | Adult | | Best Sellers Rank | #8,471 in Health & Household ( See Top 100 in Health & Household ) #5 in Sports Nutrition Post Workout & Recovery Products | | Brand Name | EFX Sports | | Container Type | Bottle | | Customer Reviews | 4.9 4.9 out of 5 stars (80) | | Date First Available | February 14, 2019 | | Diet Type | Vegan | | Dosage Form | Powder | | Flavor | Rainbow Candy | | Item Form | Powder | | Item Weight | 2.17 kg | | Manufacturer | All American Pharmaceutical | | Manufacturer | All American Pharmaceutical | | Manufacturer Part Number | AAP113RC-2 | | Material Features | Gluten Free, Sugar Free, Vegan | | Number of Items | 1 | | Package Dimensions | 10 x 6.02 x 5.91 inches; 4.78 pounds | | Primary Supplement Type | Carbohydrates | | Product Benefits | Energy Management | | Special Ingredients | Gluten Free | | Total Servings Per Container | 37 | | UPC | 737190006535 | | Unit Count | 68.8 Ounce | ## Product Details - **Age Range (Description):** Adult - **Brand:** EFX Sports - **Diet Type:** Vegan - **Flavor:** Rainbow Candy - **Item Form:** Powder - **Item Weight:** 2.17 kg - **Primary Supplement Type:** Carbohydrates - **Product Benefits:** Energy Management - **Special Ingredients:** Gluten Free - **Unit Count:** 68.8 Ounce ## Images ![- Karbolyn Fuel | Fast-Absorbing Carbohydrate Powder | Carb Load, Sustained Energy, Quick Recovery | Stimulant Free | 35 Servings (Rainbow Candy) - Image 1](https://m.media-amazon.com/images/I/61oBn5q2fAL.jpg) ## Available Options This product comes in different **Size, Flavor** options. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/142574868-karbolyn-fuel-fast-absorbing-carbohydrate-powder-carb-load-sustained-energy](https://www.desertcart.tn/products/142574868-karbolyn-fuel-fast-absorbing-carbohydrate-powder-carb-load-sustained-energy) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-10-13*
