NutrID Electrolytes is specially developed for two purposes. In the first place, when using the NutrID Kerosine / KerosineRS+, add the electrolyte powder to the water bottles in order to keep the fluid and salt balance in the body right when rinsing with water after a Kerosene shot. Secondly, the use of the NutrID electrolytes has been developed to ‘load’ the electrolytes/salts in the two days before the race. Similar to the pre race carb loading. All this plays a role in long endurance sports events (in the heat) where a lot of fluid and salt loss plays a role. Think of half or full distance triathon, (ultra) marathon, cycling classic or MTB marathon.
