A combination of maltodextrin and fructose is commonly used when making higher-carbohydrate endurance drinks. The ideal formulation depends on your target carbohydrate intake and individual tolerance.
While a traditional 2:1 glucose-to-fructose ratio has been the standard for decades, recent groundbreaking research from Massey University changed the game. The study showed that a 1:0.8 maltodextrin-to-fructose ratio significantly increases total carbohydrate oxidation efficiency and comfort compared with other ratios.
