EFX Sport Karbolyn
About this item
EFX Sports Karbolyn Fuel is a carbohydrate powder. Each scoop has 50 grams of carbohydrate and 200 calories, all from Karbolyn, which the label describes as a homopolysaccharide derived from potato, rice and corn. A 4.3 lb (1950 g) tub has about 35 to 39 servings, depending on flavor.
EFX describes Karbolyn as a performance carbohydrate and says it is absorbed about as quickly as dextrose. The label suggests one scoop in 16 ounces of water about 30 minutes before exercise. The tub carries the Informed Sport mark, and EFX says it is made in the USA.
We carry Blue Razz Watermelon, Cherry Limeade, Fruit Punch, Kiwi Strawberry, Lemon Ice, Neutral, Orange Shockwave and Strawberry. Neutral has no added flavor, so it mixes into a shake or other drink.
Pick up a tub at Elite Nutrition in Hoover or Vestavia Hills, just south of Birmingham. Not sure which carb supplement fits your plan? Ask our team.
