What's different?
Tailwind Nutrition Endurance Fuel declares 620mg sodium — more than Transparent Labs Hydrate (500mg). Transparent Labs Hydrate declares 250mg potassium — more than Tailwind Nutrition Endurance Fuel (180mg). Tailwind Nutrition Endurance Fuel declares 50g sugar — while Transparent Labs Hydrate declares none (0g). Transparent Labs Hydrate does not declare chloride, carbohydrates, calories in our source, so those cells stay blank rather than zero.
