UPC: 737190002032
EFX Sports Karbolyn Fuel is a carbohydrate supplement powder designed to provide rapid and sustained energy for athletic performance and recovery. 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 a sugar crash. The product is formulated to support glycogen loading before, during, or after intense training sessions.
This product is notable for its manufacturing process: EFX Sports produces it in-house, which they claim ensures label accuracy and purity, with each batch third-party tested and certified by Informed Sport for banned substances. It is sugar-free, gluten-free, and stimulant-free, with the Neutral variant containing no added flavors or sweeteners. Available in multiple flavors like Blue Razz Watermelon and Fruit Punch, it comes in 2.2 lb and 4.4 lb sizes, with the Neutral option specifically noted for stacking with other supplements.
