EFX Sports Karbolyn® Fuel, Kiwi Strawberry, 4 lb 4.8 oz (1,950 g)

EFX Sports Karbolyn® Fuel is a carbohydrate supplement powder designed for athletes seeking rapid energy and sustained fuel during training or events. Its key ingredient is Karbolyn®, a homopolysaccharide derived from GMO-free potato, rice, and corn, which the manufacturer states is clinically studied and enters the bloodstream faster than dextrose without causing bloating or crashes. The product is sugar-free, gluten-free, and stimulant-free, with a formulation intended to support glycogen loading and recovery.

Notably, EFX Sports manufactures its own products in-house, which they claim ensures purity and consistency, with each batch certified by Informed Sport for banned-substance testing. The Kiwi Strawberry flavor is part of a range that includes options like Blue Razz Watermelon, Cherry Limeade, and Neutral, available in 2.2 lb and 4.4 lb sizes. This variant uses sucralose for sweetness and is gluten-free.
