You want a product that allows effective electrolyte replenishment under any weather condition, any length of exercise, and any intensity of exercise. Hammer Nutrition Endurolytes Electrolyte Replacement Capsules, unlike any other pill, tablet, or premixed drink, are that product. Also, don't make the mistake of thinking that electrolytes = sodium. Sodium alone cannot and will not effectively replenish electrolyte needs and may cause more problems than it resolves. With Endurolytes you're assured of getting all the right minerals in exactly the right balance. Endurolytes comes in conveniently dosed capsules or powder form. You can swallow them, or open them and mix your own amount into your water bottle, whichever is most convenient for you
